Description

[Technical Field]

[0001] The present disclosure relates to a body-worn item, a method for manufacturing the body-worn item, and a method for reading identification information. [Background technology]

[0002] Conventionally, identification information for identifying a product has been attached to manufactured and sold products. By using the identification information, it is possible to manage, for example, the manufacturing information, design information, shipping information, sales information, usage history, and failure history of the product.

[0003] In recent years, it has become possible to manufacture products using three-dimensional additive manufacturing, allowing products to be manufactured and sold according to individual user specifications. When manufacturing products using three-dimensional additive manufacturing, after the product is formed, there are post-processes such as removing support members, separating excess material, cleaning, drying, UV irradiation, heat curing, polishing, and coating, followed by quality inspection. In this situation, it is important to properly manage each product and improve so-called traceability.

[0004] For example, the product provision system described in Patent Document 1 can provide a product desired by a user by accepting user customization of the 3D model data when manufacturing a three-dimensional object based on 3D model data selected by the user using a three-dimensional lamination method. Customization involves adding characters such as a name, a message, a place of purchase, a purchase date and time, and individual identification information to any position in the 3D model data, and adding these characters to the surface or interior of the product (three-dimensional object) to be provided, thereby ensuring the traceability of the product (three-dimensional object).

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2019-207557 Summary of the Invention [Problem to be solved by the invention]

[0006] However, in Patent Document 1, since identification information is directly added to the surface or inside of the provided product (three-dimensional object), there is a risk that the original appearance and functionality of the product (three-dimensional object) may be impaired. For example, in the case of products worn by users, such as clothing, footwear, and accessories, it is particularly important to ensure the original appearance and functionality of the product.

[0007] Therefore, the present disclosure aims to provide a body-worn item that can be appropriately managed using identification information while maintaining the original appearance and functionality of the product, a method for manufacturing a body-worn item, and a method for reading identification information attached to such a body-worn item. [Means for solving the problem]

[0008] One aspect of the present disclosure is a body-worn item that is used by fitting it along a part of the body, and includes an identification information section that is provided inside the body-worn item and that displays identification information that identifies the body-worn item on at least a part of it, and a connection section that connects the inside of the body-worn item to the identification information section.

[0009] Another aspect of the present disclosure is a method for reading identification information of a body-worn item, which involves capturing an image of an identification information section of the body-worn item, searching a database in which identification information presented by the identification information section and an image of the identification information section are stored in association with each other, obtaining an image of the identification information section from the database that is similar to the image of the captured identification information section, and determining that the identification information associated with the obtained image of the identification information section is the identification information presented by the image of the captured identification information section.

[0010] Yet another aspect of the present disclosure is a method for manufacturing a body-worn item to be used to fit a part of the body, comprising: preparing first shape data relating to the shape of a main body of the body-worn item; preparing second shape data relating to the shape of an identification information section provided inside the main body of the body-worn item and displaying identification information that identifies the body-worn item in at least a portion of the section; preparing third shape data relating to the shape of a connection section that connects the inside of the body-worn item to the identification information section; generating fourth shape data relating to the shape of the body-worn item by trimming the inside of the first shape data and adding the second shape data and the third shape data; and simultaneously molding the main body of the body-worn item, the identification information section, and the connection section based on the fourth shape data using a material that will form the main body of the body-worn item so that the identification information section becomes part of the main body of the body-worn item. [Effects of the Invention]

[0011] According to the present disclosure, there are provided a body-worn item that can be appropriately managed using identification information while maintaining the original appearance and functionality of the product, a method for manufacturing a body-worn item, and a method for reading identification information attached to such a body-worn item.

[0015] [First embodiment] The body worn products according to the embodiments of the present disclosure (body worn products 100 (FIG. 1) and body worn products 200 (FIG. 2A) described below) are body worn products 100 and 200 that are used by fitting them along a part of the body, and include identification information sections 110 and 210 that are provided inside the body worn products 100 and 200 and that display identification information for identifying the body worn products 100 and 200 on at least a part of the identification information sections, and connection sections 120 and 220 that connect the inside of the body worn products 100 and 200 to the identification information sections 110 and 210. In the following description, footwear 100 and an insole 200 are used as examples of the body worn products 100 and 200.

[0016] [Footwear and insole configuration] FIG. 1 is an external side view showing an outline of footwear 100 (body wearable item) according to an embodiment of the present disclosure.

[0017] 1, footwear 100 (body worn item) includes an identification information unit 110 and a connection unit 120. Identification information unit 110 is provided inside footwear 100, and at least a portion of it displays identification information that identifies footwear (body worn item) 100. Connection unit 120 is configured to connect the inside of footwear (body worn item) 100 with identification information unit 110.

[0018] In the following description, an example will be described in which, in the footwear 100 according to this embodiment, the identification information unit 110 is provided inside the footwear main body 102, and the connection unit 120 is configured to connect the inside of the footwear main body 102 and the identification information unit 110. That is, in the following description, an example will be described in which the footwear 100 is composed of the footwear main body 102, the identification information unit 110, and the connection unit 120. The footwear main body 102 is a part of the footwear 100 that defines the general shape of the footwear 100. As will be described later, in this embodiment, shape data of the footwear 100 is generated by cutting out a portion of the shape data of the footwear main body 102, and adding shape data corresponding to the shape of the identification information unit 110 and shape data corresponding to the shape of the connection unit 120 to the cut-out portion, and the footwear 100 can then be molded using, for example, a three-dimensional additive manufacturing method based on the generated shape data of the footwear 100.

[0019] Footwear 100 configured from footwear main body 102, identification information unit 110, and connection unit 120 is merely an example, and footwear 100 according to the present embodiment may further include other components. Furthermore, footwear 100 may be configured to be formed by combining identification information unit 110 and connection unit 120 with one or more other components instead of footwear main body 102. In other words, in the following description, an example is given in which footwear 100 is configured from footwear main body 102, identification information unit 110, and connection unit 120, but embodiments according to the present disclosure are not limited to this and may include other aspects as long as they do not deviate from the scope of the claims.

[0020] Footwear 100 is manufactured by using the above-described shape data to form footwear main body 102, identification information section 110, and connection section 120 together using, for example, a three-dimensional lamination method. Examples of the forming method include a material extrusion method such as FDM (Fused Deposition Modeling), a photolithography method such as DLP (Digital Light Processing), SLA (Stereolithography), LCD (Liquid Crystal Display), powder bed fusion method such as SLM (Selective Laser Melting), EBM (Electron Beam Melting), and inkjet printing, and an appropriate method may be used depending on the shape, function, design, and material of footwear main body 110 to be manufactured.

[0021] The connection portion 120 connects the footwear main body 102 and the identification information unit 110. In the example shown in FIG. 1 , for example, a plurality of beam-shaped members 120B (120B-1, 120B-2, 120B-3, 120B-4, 120B-5, and 120B-6) are provided as the connection portion 120. Of the plurality of beam-shaped members 120B, the beam-shaped members 120B-1, 120B-2, and 120B-3 are configured to connect the front portion 102F of the footwear main body 102 in the foot length direction to the identification information unit 110, and the beam-shaped members 120B-4, 120B-5, and 120B-6 are configured to connect the rear portion 102R of the footwear main body 102 in the foot length direction to the identification information unit 110. That is, for cross section 104F of the front portion 102F, the identification information unit 110 is connected to the footwear main body 102 by connecting portion 120 so that beam-shaped members 120B-1, 120B-2, and 120B-3 connect cross section 104F and the identification information unit 110, and for cross section 104R of the rear portion 102R, beam-shaped members 120B-4, 120B-5, and 120B-6 connect cross section 104R and the identification information unit 110.

[0022] The identification information section 110 may have, for example, a two-dimensional code in which the identification information of the footwear 100 is encoded. Other examples of the identification information section 110 will be described later.

[0023] It should be noted that the three-dimensional lamination method may be used to form not only the footwear 100 (the entire footwear) as shown in FIG. 1, but also an insole, which is a part of the footwear.

[0024] 2A is an external perspective view showing an overview of insole 200 (body-worn item) according to one embodiment of the present disclosure. As shown in FIG. 2A, insole 200 (body-worn item) includes identification information section 210 and connection section 220. In the following description, an embodiment of the present disclosure will be exemplified in which insole 200 is composed of insole body 202, identification information section 210, and connection section 220.

[0025] The insole 200 is manufactured by molding the insole body 202, the identification information section 210, and the connection section 220 together using a three-dimensional lamination method.

[0026] 2A , for example, a plurality of beam-shaped members 222B (222B-1, 222B-2, 222B-3, 222B-4, 222B-5, and 222B-6) are provided as the connecting member 220. Of the plurality of beam-shaped members 222B, beam-shaped members 222B-1, 222B-2, and 222B-3 are configured to connect a front portion 22F of the insole body 202 in the foot length direction to the identification information section 210, and beam-shaped members 222B-4, 222B-5, and 222B-6 are configured to connect a rear portion 202R of the insole body 202 in the foot length direction to the identification information section 210.

[0027] FIG. 2B shows an example of the identification information section 210. FIGS. 2A and 2B illustrate a case where the identification information section 210 is provided on a cross section of the insole 200. As shown in FIG. 2B, the identification information section 210 may be, for example, a regular pentagonal or rectangular geometric shape 212g-1 and a geometric shape 212g-2, a character 212c, or a combination of a geometric shape and a character. Other examples and combinations of the identification information section 210 will be described later. Note that, hereinafter, the geometric shape 212g-1 and the geometric shape 212g-2 and the character 212c shown in FIG. 2B are also collectively referred to as the identification information structure 212.

[0028] The footwear body 102 and the insole body 202 are shaped, for example, from 3D model data based on scan data of the user's foot, and are shaped to fit the shape of the user's foot.

[0029] The identification information unit 110 and the connecting unit 120 are simultaneously molded together with the footwear main body 102. Here, "simultaneously" includes the period during which the footwear main body 102 is molded, and "simultaneous molding" refers to the footwear main body 102, the identification information unit 110, and the connecting unit 120 being completed together in a single molding run. The identification information unit 110 includes identification information that identifies the footwear 100. Note that in this embodiment, the identification information presented by the identification information unit 110 may have a size and resolution that can be recognized by the naked eye, or may have a size and resolution that cannot be recognized by the naked eye but can be recognized as an image by a computer, for example.

[0030] The identification information portion 110 and the connection portion 120 may be formed from the same material as that forming the footwear main body 102, or may be formed from a different material and / or a different color than that forming the footwear main body 102.

[0031] Similarly, the identification information portion 210 is simultaneously molded together with the insole body 202 and includes identification information that identifies the insole body 202. The connecting portion 220 connects the insole body 202 and the identification information portion 210. The identification information portion 210 and the connecting portion 220 may be molded from the same material as that used to mold the insole body 202, or may be molded from a different material and / or a different color than that used to mold the insole body 202.

[0032] <Identification information> In this embodiment, the identification information provided by the identification information unit 210 may be associated with at least one of manufacturing information related to the manufacturing process of the body-worn items (footwear 100 and insole 200) and user information related to the user of the body-worn items. Fig. 3 is a diagram for explaining information managed in the footwear 100 or insole 200 according to one embodiment of the present disclosure. As shown in Fig. 3, the footwear and insole manufactured using the three-dimensional layering method are delivered to the user through steps S302 to S320.

[0033] In step S302, the user, for example, visits a store equipped with a 3D scanner and scans their footprint. Here, customer information, including the user's name, address, contact information, age, and gender, as well as the user's footprint, the scan date and time, and the scan data, are recorded. In step S302, further physical information related to the body that may affect changes in the product due to use may also be recorded. For example, the recorded information may include information on the user's height, weight, gender, and / or the size or shape of the body part corresponding to the product, movement habits, etc. Information on movement habits may include, for example, information on walking or running habits (e.g., pace, stride width, pronation angle and type, ground contact type, foot pressure, etc.). If the product is a shoe or insole, the size or shape of the body part corresponding to the product may include, for example, foot size, arch size, width or height, foot shape, etc.

[0034] Furthermore, when a user orders a product, product information regarding the product type, product shape, color, etc. may be included in the recorded information. For example, the user inputs the product type (model), product shape, and / or color of a desired product using a terminal installed in a store or a terminal such as the user's smartphone. Here, the desired product may be a product that the user intends to order (including a product that the user intends to actually order and a product that the user intends to order). Furthermore, the product shape and color may be set in detail for each product and product part. Furthermore, the product information is not limited to information that is intended to be ordered, but may also include preference information including the user's preferred product type (model), product shape, and / or color.

[0035] The product desired by the user may be a custom-made product, a product manufactured in small lots, or a product manufactured in large quantities and sold commercially.

[0036] In step S302, the user may, for example, visit a store that has a 3D scanner installed to scan their footprint, or may participate in a sales promotion event and scan their footprint. Alternatively, the user may scan their footprint at home using a smartphone or the like. In this way, the location where the footprint is scanned is not limited, and the footprint may be scanned at a suitable location according to the user's preference and convenience.

[0037] In step S304, a homologous modeling process of the user's footprint is performed based on the scan data acquired in step S302. Here, homologous model data is generated as a three-dimensional image of the user's footprint.

[0038] In step S306, footwear or insoles that fit the user's foot shape are designed based on the homologous model data generated in step S304. Here, 3D model data of the user's footwear or insoles is generated, and information about the creator of the 3D model data is also recorded. Information and versions of the system, software, and hardware used may also be recorded. Note that if the 3D model data is generated automatically, the creator need not be recorded. Customer preferences, intended use, and custom design information may also be recorded. If previous 3D model data exists, updates may also be recorded. Furthermore, specification information about the product, such as the shape or material of the product, type, intended use, or last (shoe mold), may also be recorded. Here, type may be information about any of insoles, shoes, and sandals, for example. Use may be information about a specific sport or activity, such as running, walking, soccer, or tennis. Last may be information about the last on which the product was designed, particularly, for example, whether an existing product last was used or whether a last tailored to the user's foot shape was used.

[0039] In step S308, footwear or insoles are modeled using a three-dimensional additive manufacturing method based on the 3D model data generated in step S306. Here, information regarding the modeling date and time, materials used, modeling conditions, modeling location, device serial number, and modeling technician is recorded. The materials used are information regarding the materials used to model the footwear or insoles using a three-dimensional additive manufacturing method, and may include, for example, information regarding the type, weight, and material lot of the material. The modeling conditions may include information regarding the three-dimensional additive manufacturing method (modeling device) used to model the footwear or insoles, the production lot, and the like.

[0040] In step S310, post-processing is performed on the footwear or insole printed in step S308. Post-processing may include, for example, peeling the footwear or insole printed in step S308 from the platform, cleaning off excess resin, post-curing, removing support material, polishing, and coating. Here, information about the date and time of post-processing, process time, processing conditions, and processing personnel may be recorded. Processing conditions may include, for example, information about the equipment, tools, heating temperature and time, and coating materials used in post-processing, or information about the environment and product conditions obtained during manufacturing.

[0041] In step S312, a quality check is performed on the footwear or insole post-processed in step S310, where information about the date and time of the check, the person in charge of the quality check, the quality inspection results, the weight, and other product characteristics are recorded.

[0042] The information recorded in steps S306, S308, S310, and S312 may be information automatically acquired from the device that performed the process, or may be information input by the operator.

[0043] In step S314, the footwear or insoles that have undergone the quality check in step S312 are shipped, and the shipping date and time are recorded.

[0044] In step S316, the footwear or insoles shipped in step S314 are received, for example, by the purchaser, and the date and time of receipt is recorded.

[0045] In step S318, the user uses the footwear or insole received in step S316. Here, the start date and time of use of the footwear or insole, the usage history date and time, and the end date and time of use are recorded. The start date and time of use and the end date and time of use may be input by the user, for example, via a dedicated application installed on a smartphone, or may be acquired and recorded by other means. The usage history date and time is a history of use of customer service, etc., and may be input by customer service or the user along with the details of the use. Note that the usage details may be, for example, information regarding the usage situation that affects changes in the product due to use. For example, it may include information regarding the frequency of use of the product by the user, the usage time, the usage intensity, the usage distance, the road surface conditions at the time of use (e.g., concrete, dirt, grass, tartan, etc.), etc. Regarding the usage time, for example, the start date and time of use, the usage history date and time, and the end date and time of use are recorded. The start date and time of use and the end date and time of use may be input by the user, for example, via a dedicated application installed on a smartphone, or may be acquired and recorded by other means. The usage history date and time is a history of using customer service, etc., and may be entered by customer service or the user along with the details of the use. If the product is a shoe or insole, the usage details may include, for example, information about the frequency, duration, intensity, etc. of walking or running.

[0046] In step S320, the user discards the footwear or insole used in step S318. Here, the date and time when the user discards the footwear or insole is recorded. The discard date and time may be input by the user as described above, or may be obtained and recorded by other means.

[0047] In this way, the information and data generated, acquired, and recorded in each series of processes are managed by being linked to, for example, identification information (control number) corresponding to the user's footwear main body 102 or insole main body 202. That is, information including customer information and manufacturing information (manufacturing process information) related to the footwear 100 or insole 200 is managed collectively using the identification information (control number). This ensures traceability that enables information related to the footwear 100 or insole 200 to be tracked based on the identification information (control number).

[0048] Because the identification information (control number) is included in the identification information section 110 (identification information section 210) formed together with the footwear main body 102 (insole main body 202), it is possible to reduce the possibility of discrepancies occurring in the association between the identification information (control number) and the footwear 100 (insole 200). For example, based on the identification information (control number), users and manufacturers can easily check the customer information and manufacturing information (manufacturing process information) described above for the footwear 100 (insole 200) corresponding to the identification information (control number).

[0049] The identification information (control number) may be assigned, for example, when the 3D model data is generated in step S306. If the identification information (control number) is assigned in step S302, the product and the customer are linked, making it possible to link who selected or purchased what model, with what footprint. If the identification information (control number) is assigned in step S304, a model is created from the footprint at that time, making it possible to understand in step S306 why the user selected or purchased this model. If the identification information (control number) is assigned in step S306, the manufactured model is linked to the product.

[0050] The identification information (control number) may be composed of, for example, letters, numbers, symbols, etc., and may be recorded in a database so as to link each piece of information and data. Furthermore, the identification information (control number) is not limited to being composed of letters, numbers, symbols, etc., but may also be composed of, for example, Braille, barcodes, two-dimensional codes, geometric shapes, or other unique shapes that conform to any rule. The identification information may also include at least one of barcodes, two-dimensional codes, letters, geometric shapes, and combinations of two or more of these. The identification information may also include not only the control number, but also the actual size of the footwear or insole, the user's name, etc.

[0051] Furthermore, for example, image information may be used as the identification information. For example, the identification information units 110 and 210 may be configured to present identification information generated by, for example, selecting an image of a user's choice and converting the selected image into a binary image.

[0052] Furthermore, the manufacturing information associated with the identification information provided by the identification information units 110 and 210 may include information that is commonly assigned to a plurality of footwear 100 and insoles 200 manufactured in the same lot.

[0053] Furthermore, for example, in the above steps S308, S310, S312, S314, etc., photographs may be taken of the manufacturing process of the product, etc., and the captured images may be stored in a database, etc. For example, such captured images may be stored in association with identification information, and the captured images may be confirmed based on the identification information when confirming information on the manufacturing process after shipping, etc.

[0054] For example, a two-dimensional code may be used as the identification pattern representing the identification information held by the identification information unit 110 and the identification information unit 210. The two-dimensional code used as the identification information in this embodiment may be generated by combining multiple rectangles, or may be generated by combining multiple squares, for example.

[0055] In addition, in this embodiment, the shape indicating the identification information may be, for example, a rectangle, a square, a polygon (e.g., a pentagon), a circle, an ellipse, a parallelogram, a cross, an L-shape, or a chord shape.

[0056] The footwear 100 and insole 200 according to this embodiment may be formed, for example, with a three-dimensional structure. FIG. 4 shows a perspective view of an example of a unit lattice structure LS of the three-dimensional structure that constitutes the footwear 100 and insole 200. As shown in FIG. 4 , in this embodiment, the three-dimensional structure that constitutes the footwear 100 and insole 200 may have a three-dimensional lattice structure, such as a lattice structure in which branched unit lattice structures are periodically arranged. The unit structure of the lattice structure shown in FIG. 4 is formed, for example, with branched structural components having a diameter d, and the dimensions of one unit lattice structure in the X, Y, and Z directions are, for example, Lx, Ly, and Lz. The footwear body 102 of the footwear 100 according to this embodiment and the insole body 202 of the insole 200 may be formed, for example, with the unit lattice structures illustrated in FIG. 4 periodically arranged.

[0057] Fig. 5 shows an enlarged cross section of a portion of insole body 202 where identification information unit 210 is provided. As shown in Fig. 5, for example, of unit lattice structures LS1, LS2, LS3, LS4, LS5, and LS6, identification information unit 210 is connected to LS2, LS3, LS5, and LS6 via beam-like members 222B-1, 222B-2, 222B-3, and 222B-4 of connecting portion 220. Similarly, footwear 100 shown in Fig. 1 may be configured such that identification information unit 110 is connected via connecting portion 120 to some of the unit lattice structures that make up footwear body 102.

[0058] 2A , for example, when the identification information unit 210 is provided in a planar manner on the cross section of the insole 200, and if a unit lattice structure exists on the same plane, the identification information unit 210 may be connected to the insole main body 202 via a beam-like member 222 with respect to such a unit lattice structure on the same plane. Also, when a unit lattice structure does not exist on the same plane as the plane on which the identification information unit 210 is provided, for example, the identification information unit 210 may be connected to the insole main body 202 via a beam-like member 222 with respect to a unit lattice structure existing in front of and / or behind the identification information unit 210 (in the +Y direction and / or the −Y direction in FIG. 2A ). Furthermore, the identification information unit 210 may be connected to the insole main body 202 via a beam-like member 222 with respect to both a unit lattice structure on the same plane as the plane on which the identification information unit 210 is provided and a unit lattice structure existing in the +Y direction and the −Y direction of the identification information unit 210. As a result, in either case, the identification information unit 210 can be fixed to the main body unit 202 by being integrally connected to the unit lattice structure surrounding the identification information unit 210. Similarly, the identification information unit 110 of the footwear main body 100 can be fixed to the main body unit 102 by being connected via beam-shaped members 122 to a unit lattice structure that exists on the same plane as the plane on which the identification information unit 110 is provided, or to a unit lattice structure that exists in the +Y direction and / or the −Y direction of the identification information unit 110.

[0059] In this embodiment, the identification information held by the identification information units 110 and 210 may be shaped as a three-dimensional structure exhibiting at least one of a barcode, a two-dimensional code, a character, a geometric shape, and a combination of two or more of these. That is, in this embodiment, for example, the identification information units 110 and 210 may be shaped by forming at least one three-dimensional shape of a barcode, a two-dimensional code, a character, a geometric shape, and a combination of two or more of these using a three-dimensional lamination method.

[0060] In the present embodiment, the identification information units 110 and 210 may be provided by forming at least one of a barcode, a two-dimensional code, characters, a geometric shape, or a combination of two or more of these on the surface of the plate-like member. For example, characters, symbols, etc. may be provided in a convex or concave shape on the surface of the plate-like member.

[0061] When a shape, symbol, letter, etc. that presents identification information is provided on the surface of a plate-like member, for example, the shape, symbol, letter, etc. that presents identification information is formed on one surface of a rectangular plate-like member. Alternatively, the surface on which the shape, symbol, letter, etc. that presents identification information is formed is not limited to one surface of the plate-like member, and the shape, symbol, letter, etc. that presents identification information may be provided on two or more surfaces.

[0062] Furthermore, shapes, symbols, letters, etc. that represent the identification information may be formed in the form of holes (punching) that penetrate from one surface of the plate-like member to the opposite surface.

[0063] The shape of the plate-like member that constitutes the identification information section 110 is not limited to a rectangular plate, but may be, for example, a circular, elliptical, oblong, or other polygonal plate.

[0064] Furthermore, in this embodiment, the identification information units 110 and 210 may be shaped so that two or more of barcodes, two-dimensional codes, characters, geometric shapes, and combinations of two or more of these are spaced apart by a predetermined distance or more and are present inside the body wearable products 100 and 200. An identification information structure 212 constituting the identification information unit 210 in this case will be described with reference to Figures 6, 7, 8, and 9.

[0065] 6 and 7 show an example of an identification information structure 212 provided on the insole body 202 according to this embodiment. Also, Fig. 8 and Fig. 9 show an example of an identification information structure 912 provided on the insole body 902 of a comparative example.

[0066] As shown in FIG. 6, in this embodiment, the identification information structures 212 (geometric identification information structures 212-g1, 212-g2, 212-g3 and character identification information structure 212-c5) are spaced apart by a predetermined distance or more. With this configuration, in the insole 200 according to this embodiment, it is possible to suppress a decrease in the shape and functionality of the insole 200 due to the spacing of the identification information structures 212, as will be described later. Furthermore, this configuration also makes it relatively easy to read the identification information presented by the identification information unit 210.

[0067] 8 , the geometric identification information structures 912-g1, 912-g2, 912-g3, and 912-g4 and the character identification information structure 912-c5 are shaped to overlap one another. For example, when the identification information structures 912 overlap with no spacing between them, as in the insole body 902 of the comparative example, the overlapping portions of the identification information structures 912 form a high-density structure, which may reduce the shaping ability of the insole body 902 during manufacturing and the functionality of the manufactured insole body 902. Similarly, when the spacing between the identification information structures 912 is less than a predetermined distance, this may reduce the shaping ability of the insole body 902 during manufacturing and the functionality of the manufactured insole body 902, as in the insole body 902 of the comparative example. Furthermore, when the identification information structures 912 are formed to overlap each other, as in the insole 902 according to the comparative example, it may be difficult to read the identification information presented by the identification information section 910. Therefore, in this embodiment, the identification information structures 212 may be arranged at least a predetermined distance apart.

[0068] 6, for example, distances D12, D23, and D34 between geometric identification information structures 212-g1, 212-g2, 212-g3, and 212-g4 of the identification information structure 212 may be configured to be greater than distance D45 between the geometric identification information structure 212-g4 and the character identification information structure 212-c5. In the example of Fig. 6, the character 212-c1 has more space inside than the geometric shapes 212-g1, 212-g2, 212-g3, and 212-g4, so that the identification information presented by the identification information structure 212 can be read even if the distance to the other identification information structures 212 is relatively short.

[0069] It should be noted that, in the insole 200 according to this embodiment, the identification information structures 212 may be spaced further apart, not limited to the example shown in Fig. 6. For example, as shown in Fig. 7, the distances D23 and D34 between the geometric identification information structures 212-g2, 212-g3, and 212-g4, and the distance D45 between the geometric identification information structure 212-g4 and the character identification information structure 212-c5 may be configured to be larger than those shown in Fig. 6.

[0070] 7, none of the identification information structures 212 may extend beyond the contour C2 of the insole main body 202. For example, as shown in FIG. 9, in the insole main body 902 of the comparative example, the identification information structures 912-g2, 912-g3, 912-g4, and 912-c5 partially extend beyond the contour C9 of the insole main body 902. In this case, when the identification information section 910 provided on the insole main body 902 is read, it is possible that a structure or pattern other than the identification information structures 912-g2, 912-g3, 912-g4, and / or 912-c5, which is formed at a position where the identification information structures 912-g2, 912-g3, 912-g4, and / or 912-c5 are expected to be formed, may be read. Furthermore, when reading the identification information section 210 provided on the insole body 902, if an attempt is made to read the identification information structure 912 formed within the outline of the insole body 902, it may be possible that, for example, some of the identification information structures 912-g2, 912-g3, 912-g4, and 912-c5 formed beyond the outline cannot be read.

[0071] Structures or patterns other than the read identification information structures 912-g2, 912-g3, 912-g4, and / or 912-c5 cannot be determined to match the structures or patterns of the identification information structures 912-g2, 912-g3, 912-g4, and / or 912-c5 stored in a database or the like along with images of structures or patterns that present identification information in association with individual information, etc., and therefore, it is possible that the desired identification information of the insole main body 902 cannot be confirmed. Similarly, if only a portion of the identification information structures 912-g2, 912-g3, 912-g4, and 912-c5 that extend beyond the contour can be read, it is possible that it will be impossible to determine whether the structures or patterns match the structures or patterns of the identification information structures previously stored in a database or the like. Because this can make it difficult to read the identification information presented by the identification information unit 910, as in the insole main body 902, in this embodiment, the identification information structure 212 may be shaped so as not to extend beyond the contour C2.

[0072] 10A, 10B, and 10C, an example of a connection method for connecting the identification information units 110 and 210 to the three-dimensional lattice structures that make up the footwear main body 102 and the insole main body 202 using the connection units 120 and 220 in this embodiment will be described. Figures 10A to 10C are enlarged cross-sectional views of a portion of the insole main body 202 that illustrate a method for connecting the identification information units 110 and 210 to the footwear main body 102 and the insole main body 202.

[0073] First, as shown in Fig. 10A, a plurality of points representing the outline of the identification information structure 212 constituting the identification information section 210 and a plurality of points representing the outline of the three-dimensional lattice structure LS (three-dimensional lattice structures LS1, LS2, LS3, LS4, LS5, and LS6) constituting the insole body 202 are generated in a cross section. For example, as shown in Fig. 10A, ten points Pg1, Pg2, Pg3, Pg4, Pg5, Pg6, Pg7, Pg8, Pg9, and Pg10 are generated on the outline of the identification information structure 212-g1. Furthermore, four points PL11, PL12, PL13, and PL14 are generated on the outline of the three-dimensional lattice structure LS1. Similarly, five points PL21, PL22, PL23, PL24, and PL25 are generated on the contour of three-dimensional lattice structure LS2, four points PL31, PL32, PL33, and PL34 are generated on the contour of three-dimensional lattice structure LS3, five points PL41, PL42, PL43, PL44, and PL45 are generated on the contour of three-dimensional lattice structure LS4, eight points PL51, PL52, PL53, PL54, PL55, PL56, PL57, and PL58 are generated on the contour of three-dimensional lattice structure LS5, and six points PL61, PL62, PL63, PL64, PL65, and PL66 are generated on the contour of three-dimensional lattice structure LS6. For simplicity, the reference symbols indicating the points are omitted in Figures 10B and 10C.

[0074] Next, as shown in Fig. 10B, the distances between all points generated on the contour of the identification information structure 212 and all points generated on the contour of the three-dimensional lattice structure LS are calculated. Of the distances calculated in this manner, Fig. 10B illustrates distances D3-11, D3-12, D3-13, and D3-14, which are distances between point Pg3 on the contour of the identification information structure 212-g1 and four points PL11, PL12, PL13, and PL14 on the contour of the three-dimensional lattice structure LS1.

[0075] Next, as shown in Figure 10C, for each point Pg1, Pg2, Pg3, Pg4, Pg5, Pg6, Pg7, Pg8, Pg9, and Pg10 on the contour of the identification information structure 212-g1, the closest point PL on the contour of the three-dimensional lattice structure LS is determined, and a connection portion 220 is formed to connect the determined point PL to each point on the contour of the identification information structure 212-g1. As shown in FIG. 10C , for example, for each of points Pg1, Pg2, Pg3, Pg4, Pg5, Pg6, Pg7, Pg8, Pg9, and Pg10 on the contour of the identification information structure 212-g1, the distance D1-24 between point Pg1 and point PL24 of the three-dimensional lattice structure LS2, the distance D2-22 between point Pg2 and point PL22 of the three-dimensional lattice structure LS2, the distance D3-22 between point Pg3 and point PL22 of the three-dimensional lattice structure LS2, the distance D3-22 between point Pg4 and point PL57 of the three-dimensional lattice structure LS5, The distance D4-57 between point Pg5 and point PL57 of three-dimensional lattice structure LS5, the distance D5-57 between point Pg5 and point PL57 of three-dimensional lattice structure LS5, the distance D6-62 between point Pg6 and point PL62 of three-dimensional lattice structure LS6, the distance D7-61 between point Pg7 and point PL61 of three-dimensional lattice structure LS6, the distance D8-61 between point Pg8 and point PL61 of three-dimensional lattice structure LS6, the distance D9-32 between point Pg9 and point PL32 of three-dimensional lattice structure LS3, and the distance D10-32 between point Pg10 and point PL32 of three-dimensional lattice structure LS3 are shortest. Therefore, the connection portion 220 is formed so as to connect these closest points together.

[0076] 10A to 10C may be executed when generating shape data for the connection portion 220 on the shape data used to shape the insole 200. 10A to 10C have been described using the insole 200 as an example, but in this embodiment, the connection portion 120 (shape data for the connection portion 120 and / or shape data for the footwear 100 including the shape data for the connection portion 120) may also be generated for the footwear 100 using a similar method.

[0077] In the above description with reference to Figures 10A to 10C, an example is given in which the connection part 220 is formed by calculating the Euclidean distance, but the connection part 220 in this embodiment is not limited to this and may be formed by evaluating the distance between two points using other calculation methods such as the Manhattan distance or the Chebyshev distance.

[0078] 10A to 10C , a case has been exemplified in which the distance on the cross section shown in FIG. 10A to 10C is calculated, and the connecting portion 220 is provided so as to connect the vertices where the distance between the identification information structure 212 and the three-dimensional lattice structure LS on the cross section is shortest. However, this is not limited to this. For example, a connecting portion 220 may be provided to connect the identification information structure 212 to a three-dimensional lattice structure LS that does not exist on the cross section on which the identification information structure 212 is formed. In this case, the distance between the three-dimensional lattice structure LS and the identification information structure 212 may be calculated by a method similar to the method described above with reference to FIG. 10A to 10C , and the connecting portion 220 may be provided. For example, when the identification information structure 212 is formed on a cross section (XZ cross section) orthogonal to the Y direction, the connecting portion 220 may be formed on the XZ cross section and / or on a plane (YZ plane) orthogonal to the XZ cross section, or on any other plane intersecting the XZ plane other than the YZ plane.

[0079] 11 shows the relationship between the identification information section 210 and the connection section 220 in a cross section in the foot length direction (a cross section perpendicular to the Y direction, i.e., a cross section parallel to the X and Z directions) in the insole 200 according to this embodiment. As shown in Fig. 11, in this embodiment, for example, the beam-like member 222 of the connection section 220 may be formed so as to connect the identification information section 210 to the three-dimensional lattice structure LS on the cross section CS2 adjacent to the cross section CS1 in the Y direction from the cross section CS1 on which the identification information section 210 is formed.

[0080] In addition, in the above description, an example has been given in which the identification information portion 210 is formed on a cross section of the insole 200 in the foot width direction (a cross section perpendicular to the Y direction, i.e., a cross section parallel to the X and Z directions), but the cross section on which the identification information portion 210 is formed is not limited to this. In this embodiment, for example, the identification information portion 210 may be formed on a cross section in the foot length direction (a cross section perpendicular to the X direction, i.e., a cross section parallel to the Y and Z directions).

[0081] In this embodiment, the connecting portion 220 includes a plurality of beam-like members, each of which may be solid or hollow and have a cylindrical, rectangular, truncated conical, or irregular cross-section cylindrical shape. Figures 12A to 12E show perspective views of examples of the shape of the connecting portion 220 in this embodiment. As shown in Figures 12A, 12B, 12C, 12D, and 12E, the shape of the connecting portion 220 may be, for example, a solid cylindrical, hollow cylindrical, solid or hollow rectangular prism (e.g., a hexagonal prism), solid or hollow truncated cone, or irregular cross-section cylindrical.

[0082] 13A to 13D, examples of the shape of the beam-like member 222 of the connecting portion 220 will be described. As shown in FIG. 13A, in this embodiment, the beam-like member 222 may be formed as a surface that connects, for example, the identification information structure 212 and the three-dimensional lattice structure LS. In this case, as shown in FIG. 13A, the connecting portion 120 may have two beam-like members 122-c1 and 122-c2 that have partially curved surfaces, and may be configured to connect any two end points PL-1 and PL-2 of the three-dimensional lattice structure LS to the identification information structure 212. In another embodiment, for example, the beam-like members 122-c1 and 122-c2 shown in FIG. 13B may have a portion 122-m12 that is connected in part, and may be configured to connect each of any two end points PL-1 and PL-2 of the three-dimensional lattice structure LS to one point on the identification information structure 212.

[0083] In this embodiment, the connecting portion 120 may have rod-shaped beam members 122-s1 and 122-s2 as shown in Figures 13C and 13D. Also, as shown in Figure 13C, for example, some of the multiple beam members 122 may have bent portions 122-b2.

[0084] As shown in Figures 13A and 13B, the beam-like members 122-c1 and 122-c2 are formed as surfaces connecting the identification information structure 212 and the three-dimensional lattice structure LS, which allows, for example, the thickness of the beam-like members 122-c1 and 122-c2 to be relatively small and the strength to be increased. Furthermore, the rod-shaped beam-like members 122-s1 and 122-s2 shown in Figures 13C and 13D make it easier to ensure continuity during the formation of the beam-like structure and allows for greater freedom in shape. Furthermore, by using the rod-shaped beam-like members 122-s1 and 122-s2, for example, it is possible to relatively increase the amount of void space within the footwear 120 including the beam-like members 122-s1 and / or 122-s2. This allows, for example, liquid to flow relatively easily into the interior of the footwear 100 or the like, making it easier to clean the footwear 100 or the like.

[0085] In addition, in this embodiment, the location of the identification information unit may be visually recognized from the exterior. That is, in this embodiment, a position indicating unit having a shape indicating information about the location where the identification information units 110 and 210 are provided inside the body worn item (footwear 100 and insole body 202) may be provided on the outer surface of the body worn item.

[0086] As will be described later, in this embodiment, the identification information presented by the identification information units 110 and 210 is read by reading the identification information units 110 and 210 of the footwear 100 and the insole 200. By providing the position indicating unit on the outer surface of the footwear 100 or the insole 200, it is possible to ascertain the position where the identification pattern is embedded when reading the identification pattern by a CT scan or the like. Note that the position indicating unit may be provided, for example, on the footwear 100 in a part other than a part that contacts the ground when the product is used, or on the surface of the footwear 100 and the insole main body 202 in a part other than a part that comes into contact with a part of the user's body, and at least one geometric shape indicating the direction or position of the identification information units 110 and 210 may be formed on the outer surface together with the shape of the product. This makes it possible to prevent the markings provided by the position indicating units from disappearing due to friction or other factors when the body wearable items 100 and 200 are in use, even if the position indicating units are provided on the outer surfaces of the body wearable items 100 and 200.

[0087] For example, the position presenting unit may be provided in an upper portion when provided in footwear 100. The upper portion has little or no contact with the ground or with parts of the user's body when footwear 100 is in use, and therefore the position presenting unit can indicate the direction and position of identification information unit 110 even when footwear 100 is continuously used.

[0088] In this embodiment, an example of the shape formed and used as the position presenting unit may be, for example, an arrow shape. For example, the position presenting unit may be formed so that the tip of the arrow-shaped position presenting unit indicates the position where the identification information unit 210 is formed. Alternatively, the position presenting unit may be formed so that the direction of the arrow presented by the position presenting unit is the direction in which the identification information unit 210 is formed (for example, a direction parallel to the cross section where the identification information unit 210 is formed or a direction perpendicular to the cross section where the identification information unit 210 is formed).

[0089] In addition, in this embodiment, the position presenting unit may be triangular or polygonal, and in these cases, the position presenting unit may be arranged so that, for example, the vertex of the triangle or the point where two straight lines intersect on the polygonal line indicates the direction or position of the identification information unit 210.

[0090] A method for reading the identification information units 110 and 210 according to this embodiment will be described with reference to Fig. 14. The method for reading the identification information units 110 and 210 according to this embodiment involves capturing images of the identification information units 110 and 210 of the body-worn items (footwear 100 and insole 200), searching a database in which the identification information presented by the identification information units 110 and 210 and images of the identification information units 110 and 210 are stored in association with each other, obtaining images of the identification information units 110 and 210 similar to the captured images of the identification information units 110 and 210 from the database, and determining that the identification information associated with the captured images of the identification information units 110 and 210 is the identification information presented by the captured images of the identification information units 110 and 210. Fig. 14 is a flowchart showing the method for reading the identification information units 110 and 210 according to this embodiment.

[0091] 14, first, images of the identification information units 110 and 210 are taken (S1402). For example, if the identification information units 110 and 210 are formed on the cross sections of the footwear 100 and the insole 200, images can be taken using a scanner for computed tomography (CT) used in industrial applications.

[0092] In the process of reading the identification information units 110 and 210 according to this embodiment, for example, if a position presenting unit (e.g., position presenting unit 292 (position presenting units 292a, 292b, 292c, 292d, and 292e)) is provided on the outer surface of the body worn products 100 and 200, the position presenting unit 292 may be read first before capturing an image of the identification information units 110 and 210 (S1402). After the position presenting unit 292 is recognized, the identification information units 110 and 210 may be captured based on information relating to the orientation and position of the identification information units 110 and 210 provided by the position presenting unit 292. Furthermore, before the position presenting unit 292 is read, it may be determined whether or not the position presenting unit 292 is provided on the outer surface of the body worn products 100 and 200.

[0093] For example, the position presenting unit such as the position presenting unit 292 may be visually confirmed by the user. Alternatively, the position presenting unit such as the position presenting unit 292 may be confirmed by analyzing captured images of the body-worn devices 100 and 200 using a computer, or by shape recognition using laser irradiation of the body-worn devices 100 and 200.

[0094] Furthermore, when the identification information units 110 and 210 are imaged using a scanner for computed tomography, for example, in the case of footwear 100, a cross section perpendicular to the bottom surface of footwear 100 that comes into contact with the ground when footwear 100 is used (for example, a cross section parallel to the XZ plane or a cross section parallel to the YZ plane when the foot length direction is defined as the Y direction) may be imaged multiple times at different positions (different positions in the X and / or Y directions). Alternatively, for example, a cross section parallel to the bottom surface of footwear 100 (for example, a cross section parallel to the XY plane) may be imaged multiple times at different positions (different positions in the Z direction).

[0095] In addition, in this embodiment, when the body-worn products 100 and 200 are imaged, for example, images may be taken from various angles to obtain multiple images, and the identification information units 110 and 210, which will be described later, may be read based on the multiple images obtained. Alternatively, the body-worn products 100 and 200 may be scanned with a laser to read their shapes, thereby confirming the identification information units 110 and 210.

[0096] In this embodiment, a two-dimensional image may be generated from the body-worn products 100 and 200, and the images of the identification information units 110 and 210 and the identification information presented by the identification information units 110 and 210 may be read based on the generated two-dimensional image. For example, the identification information units 110 and 210 may be read based on a two-dimensional shadow image formed by irradiating the body-worn products 100 and 200 with light. Alternatively, the images of the identification information units 110 and 210 and the identification information presented by the identification information units 110 and 210 may be read based on a two-dimensional stamp image formed by applying a coloring material such as ink to a portion of the body-worn products 100 and 200 (for example, the heel portion of the footwear 100) and imprinting the portion to which the coloring material has been applied on a recording medium such as paper.

[0097] Next, a database in which the identification information presented by the identification information units 110 and 210 and images of the identification information units 110 and 210 are stored in association with each other is searched, and images of the identification information units 110 and 210 similar to the captured images of the identification information units 110 and 210 are obtained from the database (S1404). Note that, for example, when an identification information reading device is used in performing the method for reading the identification information units 110 and 210 according to this embodiment, the database may be stored in a storage unit included in the identification information reading device, or may be stored in a database external to the identification information reading device, and information used in performing the method for reading the identification information units 110 and 210 may be obtained by accessing the database using the identification information reading device.

[0098] In this embodiment, for example, the similarity between the images of the identification information sections 110 and 210 stored in a database and the captured images of the identification information sections 110 and 210 may be calculated, and if it is determined that the similarity is equal to or greater than a predetermined threshold, the image may be acquired. The similarity may be calculated, for example, by comparing the frequency of pixel values ​​of each image using a known method for calculating the similarity between images. Furthermore, in this embodiment, if there are multiple images whose similarity is equal to or greater than a predetermined threshold, multiple images may be acquired.

[0099] In this embodiment, for example, the pixel values ​​constituting the captured image of the identification information units 110 and 210 are compared with the pixel values ​​constituting the image of the identification information units 110 and 210 obtained from the database, and the image of the identification information units 110 and 210 obtained from the database in which the difference in pixel values ​​between the two images is small (for example, the image in which the difference in pixel values ​​between all pixels constituting the captured image of the identification information units 110 and 210 and the corresponding pixels in the image of the identification information units 110 and 210 obtained from the database is smallest) may be determined to be the image having the identification information presented by the identification information units 110 and 210 that are being captured.

[0100] Next, it is determined that the identification information associated with the acquired images of the identification information sections 110 and 210 is the identification information presented by the captured images of the identification information sections 110 and 210 (S1406). Note that, for example, as described above, if there are multiple images whose similarity is equal to or greater than a predetermined threshold and multiple images are acquired, it may be determined that the identification information associated with one of the multiple images is the identification information presented by the captured identification information sections 110 and 210.

[0101] For example, when multiple cross-sectional images taken at different positions as described above are obtained, the cross sections in which the identification information sections 110 and 210 are formed may be identified among the multiple cross-sectional images by comparing the multiple cross-sectional images with images of the identification information sections 110 and 210 obtained from a database.

[0102] [Second embodiment] Hereinafter, a method for manufacturing the body wearable products 100 and 200 according to the embodiments of the present disclosure will be described.

[0103] The manufacturing method of the body-worn products 100 and 200 (footwear 100 and insole 200) according to the embodiment of the present disclosure is a manufacturing method of body-worn products used to fit a part of the body, and includes preparing first shape data relating to the shape of the main body of the body-worn products 100 and 200, preparing second shape data relating to the shape of identification information units 110 and 210 that are provided inside the main body (footwear main body 102 and insole main body 202) of the body-worn products (footwear 100 and insole 200) and that display identification information that identifies the body-worn products (footwear 100 and insole 200) on at least a part of the body-worn products, and preparing connecting units 120 and 22 that connect the inside of the body-worn products (footwear 100 and insole 200) to the identification information units 110 and 210. Third shape data relating to the shape of 0 is prepared, and fourth shape data relating to the shapes of the body-worn items 100 and 200 is generated by trimming the interior of the first shape data and adding the second shape data and the third shape data. Based on the fourth shape data, the main body of the body-worn items 100 and 200 (footwear main body 102 and insole main body 202) is molded simultaneously with the identification information units 110 and 210 and the connection units 120 and 220 using a material for molding the main body of the body-worn items 100 and 200 (footwear main body 102 and insole main body 202) so that the identification information units 110 and 210 become part of the main body of the body-worn items 100 and 200 (footwear main body 102 and insole main body 202).

[0104] FIG. 15 is a flowchart showing a method for manufacturing the body wearable devices 100 and 200 according to an embodiment of the present disclosure.

[0105] 15, first shape data relating to the main body (footwear main body 102 and insole main body 202) is prepared (S1502). In this embodiment, the body wearable products 100 and 200 are manufactured using, for example, a three-dimensional layering method, and the first shape data may be, for example, shape data that can be formed by the three-dimensional layering method. Note that other shape data, such as second shape data, third shape data, and fourth shape data described below, may also be shape data that can be formed by the three-dimensional layering method.

[0106] Next, second shape data relating to the shapes of the identification information units 110 and 210 is prepared (S1504). That is, second shape data relating to the shapes of the identification information units 110 and 210 are prepared, which are provided inside (for example, on cross sections of) the main bodies (footwear main body 102 and insole main body 202) of the body-worn items (footwear 100 and insole 200) and which present, at least in part, identification information for identifying the body-worn items (footwear 100 and insole 200).

[0107] Next, third shape data relating to the shapes of the connecting parts 120 and 220 is prepared (S1506). That is, third shape data relating to the shapes of the connecting parts 120 and 220 that connect the inside of the body wear item (footwear 100 and insole 200) to the identification information parts 110 and 210 is prepared.

[0108] Next, the interior of the first shape is trimmed, and the second shape data and the third shape data are added to generate fourth shape data (S1508). That is, the interior of the first shape data is trimmed, and the second shape data and the third shape data are added to generate fourth shape data relating to the shapes of the body worn items 100 and 200. In this embodiment, for example, portions corresponding to the portions where the identification information units 110 and 210 are to be formed may be cut out from the first shape data so that the identification information units 110 and 210 are formed on the cross sections of the footwear main body 102 and the insole main body 202. For example, as shown in FIG. 1, the footwear main body 102 may be cut out between the front portion 102F and the rear portion 102R so that the front portion 102F and the rear portion 102R can be clearly seen. Furthermore, for cross section 104F of front portion 102F and cross section 104R of rear portion 102R, connecting portion 120 may form shape data (fourth shape data) that exhibits a shape that is connected to footwear main body 102 so that beam-shaped members 120B-1, 120B-2, and 120B-3 connect cross section 104F to identification information unit 110, and beam-shaped members 120B-4, 120B-5, and 120B-6 connect cross section 104R to identification information unit 110.

[0109] Next, the footwear main body 102, the insole main body 202, the identification information units 110 and 210, and the connecting units 120 and 220 are simultaneously formed (S1510). That is, based on the fourth shape data generated in S1502 to S1508, the main bodies of the body worn products 100 and 200 (footwear main body 102 and insole main body 202), the identification information units 110 and 210, and the connecting units 120 and 220 are simultaneously formed using the material for forming the main bodies of the body worn products 100 and 200 (footwear main body 102 and insole main body 202) so that the identification information units 110 and 210 become part of the main bodies of the body worn products 100 and 200 (footwear main body 102 and insole main body 202).

[0110] As described above, the body wearable products 100 and 200 having the identification information sections 110 and 210 can be manufactured by the manufacturing method for the body wearable products 100 and 200 according to the embodiment of the present disclosure.

[0111] In the present embodiment, the identification information units 110 and 210 and the connecting units 120 and 220 may be formed from the same material as the footwear main body 102 and the insole main body 202. By forming them from the same material, it is possible to reduce the impact of the identification information units 110 and 210 and the connecting units 120 and 220 on the original appearance (design, etc.) and functionality of the footwear main body 102 and the insole main body 202. Furthermore, because the identification information units 110 and 210 and the connecting units 120 and 220 can be assimilated into the footwear main body 102 and the insole main body 202 in terms of appearance, it is possible to reduce the sense of incongruity caused by the identification information units 110 and 210 and the connecting units 120 and 220.

[0112] It should be noted that the identification information units 110 and 210 and the connecting units 120 and 220 are not limited to being made of the same material as the footwear main body 102 and the insole main body 202. For example, they may be made of a different material as long as the material can reduce the impact on the original appearance and functionality of the footwear main body 102 and the insole main body 202, as described above.

[0113] Furthermore, the identification information units 110 and 210 and the connection units 120 and 220 may be shaped in the same color as the footwear main body 102 and the insole main body 202, or in a different color, as long as this reduces the sense of incongruity relative to the footwear main body 102 and the insole main body 202.

[0114] The connecting portions 120 and 220 may have a diameter of, for example, 1 mm or more so as to prevent the identification information portions 110 and 210 from being accidentally torn off.

[0115] Furthermore, in the process of preparing the second shape data relating to the shapes of the above-described identification information units 110 and 210, for example, when a user presents a desired shape, second shape data having the presented shape may be prepared. For example, when a user presents a favorite image or photo, second shape data having a shape including the image or photo may be generated.

[0116] <Processing Procedure> An example of the shape data generation process for footwear 100 executed in this embodiment will be described with reference to Figs. 16A to 16C. Figs. 16A to 16C are diagrams showing an overview of the shape data generation process according to this embodiment. The shape data generation process for footwear 100 shown in Figs. 16A to 16C relates to shape data generation process that allows for easy molding using a three-dimensional lamination method or the like based on the shape data (third shape data) of connection portion 120. Figs. 16A to 16C describe the shape data generation process for footwear 100 as an example, but the shape data generation process shown below can also be applied to the shape data generation process for other body articles, such as insoles 200.

[0117] First, with reference to FIG. 16A, an example of the process for generating shape data for footwear 100 executed in this embodiment will be described. As shown in FIG. 16A, first, product-related information is input (S1602). In this embodiment, for example, information regarding the type of product (type information) may be input as product-related information. For example, if footwear 100 is manufactured as a body-worn item, the information regarding the type of product may be information such as "sandals." Alternatively, if the user desires running shoes, information such as "running shoes" may be input.

[0118] Next, a position where the identification information is to be embedded is determined (S1604). That is, a position where the identification information section 110 is to be formed is determined on the footwear main body 102. The position where the identification information is to be embedded may be a predetermined position, such as the heel portion of the footwear main body 102 or a predetermined position from the forefoot portion of the footwear main body 102 (for example, a position 80% of the length of the footwear main body 102 in the foot length direction (Y direction) from the forefoot portion).

[0119] Next, shape data is generated for the identification information section 110 that represents the identification information to be assigned to the footwear 100 (S1606). For example, second shape data is generated, which is shape data corresponding to a two-dimensional code or the like that represents the identification information. At this time, as described above with reference to Figures 7 and 9, the second shape data may be generated so that the identification information structure 112 of the identification information section 110 does not extend beyond the outline of the footwear body 102.

[0120] Next, product shape data is generated (S1608). That is, shape data of the footwear 100 including the identification information section 110 (fourth shape data in this embodiment) is generated based on shape data determined by the type of product (first shape data in this embodiment), shape data representing the identification information (second shape data in this embodiment), and shape data of the connection section 120 (third shape data in this embodiment).

[0121] Next, the generated shape data is output (S1610).

[0122] In this manner, the process of generating shape data for the footwear 100 in this embodiment is executed.

[0123] Next, another example of the process for generating shape data for the footwear 100 executed in this embodiment will be described with reference to Fig. 16B. The process for generating shape data for the footwear 100 shown in Fig. 16B differs from the process for generating shape data for the footwear 100 described above with reference to Fig. 16A in that information related to the user's movements and the equipment used to model the body-worn product 100 is also input, and shape data for the footwear 100 is generated based on the input information related to the user's movements and the equipment used to model the body-worn product 100.

[0124] As shown in FIG. 16B, first, information related to the product is input (S1622). In this embodiment, the information related to the product may include, for example, information about the type of product (type information), information about the usage mode (information about the user's movement or the user's tendency to move), and information about the equipment used. The information about the type of product may be, for example, information that the product is a sandal when footwear 100 is manufactured as a body-worn item. The information about the usage mode may be information about the user's movement mode or the user's tendency to move, for example, information about the ground contact method when the user uses footwear 100. For example, the information may be information that the forefoot contacts the ground when using sandals, which are the body-worn item to be manufactured. In other words, the information may be information about the usage mode of the user who uses the manufactured product.

[0125] Furthermore, the information about the equipment to be used is information about equipment that can be used to manufacture the footwear 100, and may be information about a 3D printer, for example, when manufacturing the footwear 100 using a 3D printer or the like by three-dimensional additive manufacturing. At this time, the user may select the equipment to be used to model the footwear 100 from among a plurality of candidate equipment to be used. For example, a list of multiple equipment with different modeling methods may be displayed to the user, and the user may select the equipment they wish to use from the list. Alternatively, for example, a list of multiple equipment with the same modeling method (e.g., multiple equipment with the same manufacturer or model) may be displayed to the user along with information such as whether it is usable, whether it is broken, and whether it is in use, and the user may determine the equipment to be used by selecting an equipment that is not broken and not in use.

[0126] Next, a movement tendency is determined (S1624). The user's movement tendency may be, for example, information regarding the ground contact method when the user uses the footwear 100. The ground contact method when the footwear 100 is used may be, for example, information regarding the position where the user using the footwear 100 contacts the ground when using the footwear 100. In the example shown in FIG. 16B, for example, information that the user using the footwear 100 contacts the ground with the forefoot is input as the ground contact method.

[0127] Note that the user's usage style of the footwear 100 varies depending on the user's movement patterns and the position where the footwear touches the ground, and therefore the parts of the footwear 100 that are susceptible to deformation and wear may vary depending on the user. If the identification information unit 110 is provided in a part of the footwear 100 that is susceptible to significant deformation, the identification information unit 110 may be subjected to repeated large loads while the user is running, etc., and may undergo irreversible deformation. Such deformation may make it difficult to read the identification information presented by the identification information unit 110.

[0128] Furthermore, for example, the information regarding movement tendencies may include information regarding walking or running tendencies (for example, step rate, stride width, pronation type, and ground contact type). When a user runs while wearing footwear 100, they may run using different running styles, such as a forefoot running style, a heel strike running style, and a midfoot running style. These different running styles result in different positions on footwear 100 that are subjected to load.

[0129] Next, the type of product is determined based on the input information (S1626). For example, the type of product may be determined based on the input information on the type of product, movement tendency, or equipment used. For example, it is determined that sandals S1 will be manufactured as the product. Note that by determining the type of product, the shape data of the footwear 100 before the shape data of the identification information unit 110 (i.e., the second shape data) and the shape data of the connection unit 120 (i.e., the third shape data) are added is determined. Therefore, in this process, first shape data, which is the shape data of the footwear main body 102, is generated. Note that the shape data of the footwear main body 102 may be stored in a storage unit included in a device such as a computer that executes the shape data generation process. Alternatively, the shape data of the footwear main body 102 may be stored in a database or the like external to the device such as a computer that executes the shape data generation process and acquired from the database.

[0130] Next, the position where the identification information is to be embedded is determined (S1628). That is, the position where the identification information section 110 is to be formed on the footwear main body 102 is determined. The position where the identification information is to be embedded may be determined based on, for example, the input information related to the ground contact method. For example, the position where the identification information is to be embedded is determined to be in an area other than the area where the footwear comes into contact with the ground.

[0131] Next, the equipment to be used and the manufacturing method are determined (S1630). For example, based on the input information on the equipment to be used and the corresponding manufacturing method, it is determined that the equipment that can be used to manufacture the footwear 100 is the 3D printer P1.

[0132] Next, the minimum thickness that can be produced by the determined equipment to be used is determined (S1632). For example, information on the minimum thickness that can be produced for candidate equipment to be used, such as multiple 3D printers, may be stored in advance in a lookup table or the like, and the stored minimum thickness information may be acquired for the equipment to be determined to be used. For example, if 3D printer P1 is used as the equipment to be used, information that the minimum thickness that can be produced by 3D printer P1 is T1 may be acquired.

[0133] The minimum thickness will be described with reference to Figures 17A and 17B. Figures 17A and 17B are schematic perspective views of a shape formed by a 3D printer using a three-dimensional deposition method, for explaining the minimum thickness.

[0134] As shown in Fig. 17A, a structure 900 having a plate-shaped portion P92 with a height H2 is printed using a 3D printer P1. At this time, if the thickness T2 of the plate-shaped portion P92 is smaller than a predetermined thickness (minimum thickness T1), it may be possible to print only up to a height H4, which is smaller than H2, as shown in Fig. 17B. The lower limit of the thickness T2 at which the desired height H2 can be printed corresponds to the minimum thickness T1.

[0135] Next, shape data of the connection portion 120 is generated based on the determined minimum thickness (S1634). For example, when a cylindrical connection portion is to be formed as the connection portion 120, shape data of the connection portion 120 is generated such that the diameter of the cross section is larger than the minimum thickness so that the thickness is larger than the minimum thickness. By generating the shape data of the connection portion 120, the third shape data in this embodiment is generated.

[0136] As with the connection section 120, the identification information section 110 may also be configured so that shape data (second shape data) is generated that makes the minimum thickness greater than T1.

[0137] Next, shape data is generated for the identification information section 110, which represents the identification information to be assigned to the footwear 100 (S1636). For example, second shape data is generated, which is shape data corresponding to a two-dimensional code or the like representing the identification information. At this time, similar to the process of generating the shape data for the footwear 100 shown in FIG. 16A, the second shape data may be generated so that the identification information structure 112 of the identification information section 110 does not extend beyond the outline of the footwear body 102, as described above with reference to FIGS. 7 and 9, etc.

[0138] Next, product shape data is generated (S1638). That is, shape data of the footwear 100 including the identification information section 110 (fourth shape data in this embodiment) is generated based on shape data determined by the type of product (first shape data in this embodiment), shape data representing the identification information (second shape data in this embodiment), and shape data of the connection section 120 (third shape data in this embodiment).

[0139] Next, the generated shape data is output (S1640).

[0140] In this manner, the process of generating shape data for the footwear 100 in this embodiment is executed.

[0141] As described above for S1602 shown in FIG. 16A and S1622 and S1626 shown in FIG. 16B, in this embodiment, preparing the first shape data includes obtaining type information regarding the type of body wear item.

[0142] As described above for S1622, S1624, etc., generating the fourth shape data involves acquiring usage mode information relating to the usage mode of the body-worn item, and determining the position to trim the interior of the footwear main body 102 based on the usage mode information. In the above example, the type of body-worn item is footwear 100, and the usage mode information includes information relating to the area of ​​the footwear that comes into contact with the ground when the footwear is in use. In this embodiment, determining the position to trim includes determining an area other than the area that comes into contact with the ground as the position to trim.

[0143] Furthermore, as described above for S1636 etc., generating the fourth shape data, which is the shape data of the footwear 100, includes determining the cross section (cross sections 104F and 104R (Figure 1)) in which the identification information section 110 is formed by adding the shape data (second shape data) of the identification information section 110 inside the footwear main body 102, and adding the second shape data, which is the shape data of the identification information section 110, and the third shape data, which is the shape data of the connection section 120, to the first shape data, which is the shape data of the footwear main body 102, so that the identification information section 110 and the connection section 120 are positioned within the outline of the footwear 100, which is a body-worn item, (or the outline of the footwear main body 102) in the cross section (cross sections 104F and 104R (Figure 1)).

[0144] As described above with reference to S1622, S1626, S1632, etc., in the process of generating shape data in the manufacturing method of footwear 100 according to this embodiment, information on the equipment used is input. That is, in this embodiment, generating the third shape data includes obtaining equipment information on the equipment used to manufacture the body wear item (footwear 100), which includes information on the minimum dimensions that the equipment can manufacture, and setting the size of connection portion 120 in the third shape data to be equal to or larger than the minimum dimensions.

[0145] Next, another example of the process for generating shape data for footwear 100 executed in this embodiment will be described with reference to Fig. 16C. The process for generating shape data for footwear 100 shown in Fig. 16C differs from the process for generating shape data for footwear 100 described above with reference to Fig. 16B in that, for example, the process for determining the position at which identification information unit 110 is to be built and the process for determining the minimum thickness of the equipment used to shape footwear 100 are performed in parallel.

[0146] As shown in FIG. 16C , first, information related to the product is input (S1662). In this embodiment, the information related to the product may include, for example, information about the type of product, information about the usage mode (information about the user's movement or the user's tendency to move), information about the equipment used, and identification information to be presented by the identification information unit 110. For example, the information about the type of product may be "sandals," the information about the usage mode may be information that the forefoot touches the ground when the user uses the footwear 100, and the information about the equipment used may be information that the footwear is a 3D printer. Furthermore, for example, the user may input a two-dimensional code image as identification information to be presented by the identification information unit 110.

[0147] Next, determination of the product (S1664), determination of the built-in position based on the tendency of movement (S1666), determination of the minimum thickness of the device used (S1668), and generation of shape data of the identification information section (S1670) may be executed. At this time, determination of the product (S1664), determination of the built-in position based on the tendency of movement (S1666), determination of the minimum thickness of the device used (S1668), and generation of shape data of the identification information section (S1670) may be executed in parallel.

[0148] The product determination (S1664) may be performed based on information about the type of product input by the user, for example, similar to S1626 (FIG. 16B).

[0149] The determination of the embedding position based on movement tendency (S1666) may be based on information regarding the ground contact method, etc. input by the user, similar to S1624 and S1628 (Figure 16B), and the position at which the identification information is embedded may be determined to be in an area other than the area where the user comes into contact with the ground when using the footwear 110, so that deformation of the identification information unit 110 is suppressed when the user uses the footwear 100.

[0150] Determining the minimum thickness of the equipment to be used (S1668) may be similar to S1630 and S1632 (Figure 16B), for example, by determining the equipment to be used (e.g., 3D printer P1) based on information about the equipment to be used input by the user, and determining the minimum thickness T1 that can be produced using the determined equipment to be used.

[0151] In generating shape data for the identification information section (S1670), for example, shape data (second shape data) representing identification information such as a two-dimensional code may be generated, similarly to S1636 (FIG. 16B). For example, if the user inputs shape data such as a two-dimensional code in S1662, shape data for the identification information section 110 may be generated that includes image data of the two-dimensional code input by the user. Alternatively, if the user has not input information related to identification information, new shape data for the identification information section 110 may be generated that includes identification information generated based on information related to the user or manufacturing.

[0152] Next, similarly to S1638 and S1640 (FIG. 16B), product shape data is generated (S1672), and then the generated shape data is output (S1674).

[0153] In addition, the product determination (S1664), the determination of the built-in position based on the movement tendency (S1666), the determination of the minimum thickness of the equipment to be used (S1668), and the generation of shape data of the identification information section (S1670) may all be executed in parallel, or only some of them may be executed in parallel.

[0154] 18A and 18B, and 19A to 19C, a further example of the process for generating shape data for footwear 100 executed in this embodiment will be described. FIG. 18A is a diagram illustrating an overview of the process for generating shape data according to this embodiment. The process for generating shape data for footwear 100 shown in FIG. 18A relates to a process for generating shape data that can reduce the impact on the functionality of footwear 100 caused by the position at which identification information section 110 is formed. As with FIGS. 16A to 16C, FIGS. 18A and 18B, and 19A to 19C will describe the process for generating shape data for footwear 100 as an example. However, the process for generating shape data described below can also be applied to the process for generating shape data for other body-worn items, such as insoles 200.

[0155] In the manufacturing method of the body worn article (footwear 100) in this embodiment for evaluating such functionality, determining the cross section includes determining the cross section in the first shape data so that the cross section is located at a position corresponding to a first predetermined percentage of the foot length of the footwear in the foot length direction, in a direction from the heel of the footwear 100 toward the toe, along the foot length direction of the footwear 100; generating fourth shape data includes generating provisional shape data by adding second shape data and third shape data to the first shape data so that the identification information section 110 is formed on the determined cross section; and evaluating the functionality of the footwear formed based on the first shape data and the provisional shape data. and numerically analyzing the functionality of the footwear (100) formed based on the provisional shape data, determining whether the functionality of the footwear (100) formed based on the provisional shape data is equal to or less than a second predetermined percentage of relative error with respect to the functionality of the footwear formed based on the first shape data as a result of the numerical analysis, outputting the provisional shape data as the fourth shape data if it is determined that the functionality of the footwear (100) formed based on the provisional shape data is equal to or less than the predetermined percentage of relative error, and changing the position of the cross section in the first shape data if it is determined that the functionality of the footwear formed based on the provisional shape data exceeds the predetermined percentage of relative error.

[0156] 18A, first, shape data (first shape data) of the footwear main body 102 is acquired (S1802). For example, as described above with reference to FIG. 16B, shape data of a sandal is acquired as the shape data of the footwear main body 102.

[0157] Next, an initial position for forming the identification information portion 110 is determined (S1804). The initial position may be set to a position 10% in the direction from the heel toward the toe. Note that the initial position may be determined according to another predetermined value or by another method.

[0158] Next, the identification information structure 112 of the identification information part 110 is determined (S1806). For example, as shown in Fig. 18A, a two-dimensional code is determined as the identification information structure 112. Also, shape data (second shape data) of the identification information part 110 having the shape of the identification information structure 112 is generated.

[0159] Next, shape data (third shape data) of the connection portion 120 is generated (S1808).

[0160] 18B, a method for generating shape data (third shape data) of the connection portion 120 will be described. In this embodiment, the shape data of the connection portion 120 may be generated by a method similar to the method described above with reference to FIGS. 10A to 10C.

[0161] As shown in FIG. 18B, first, data 110d of the cross-sectional shape in which the identification information section 110 is formed and beam shape data 102d of the footwear main body 102 to which the cross-sectional shape is connected are acquired (S1842).

[0162] Next, for the cross-sectional shape 110d, virtual division lines (straight lines Lx1, Lx2, Lx3, Lx4, Lx5, Lx6, and Lx7 parallel to the Z direction, and straight lines Lz1, Lz2, and Lz3 parallel to the X direction) are set at equal intervals, and the coordinates n of the intersections are calculated. i (x i ,y i ,z i) (i is an integer equal to or less than the number of intersections) is obtained (S1844). The virtual dividing line may be set, for example, on the main surface of the cross-sectional shape. For example, if the cross-sectional shape is parallel to the XZ plane, multiple straight lines parallel to the X direction and multiple straight lines parallel to the Z direction may be set as virtual dividing lines.

[0163] Next, in the beam shape data, the coordinates v of the lattice point on the surface opposite to the cross-sectional shape on which the identification information portion 110 is formed are calculated. j (x j ,y j ,z j ) (j is an integer equal to or less than the number of lattice points) is obtained (S1846). In this embodiment, the footwear 100 is, for example, a sandal, and may be formed by a 3D printer and configured with a three-dimensional lattice structure. As shown in FIG. 18B, in the beam shape, the three-dimensional lattice structures are arranged at equal intervals, and the lattice points, which are the vertices of each three-dimensional lattice structure, are positioned at equal intervals (for example, at equal intervals in the X direction and the Z direction).

[0164] Next, at each intersection point n of the cross-sectional shape i and each lattice point v on the opposite surface of the beam shape j For example, as shown in FIG. 18B, the Euclidean distance between the two points may be evaluated according to the following formula 1.

number

[0165] Next, the closest points (calculated distance d ij The shape data (third shape data) of the connection portion 120 is generated so that the points (points for which the lattice point distance is smallest) of the cross-sectional shape are connected (S1850). Note that the acquisition of the coordinates of the intersection points in the cross-sectional shape and the acquisition of the coordinates of the lattice points in the beam shape may be performed simultaneously in parallel, or one may be performed before the other.

[0166] In this embodiment, the connecting portions 120 and 220 can be generated in various shapes, as illustrated with reference to Figures 12A to 12E. For example, the connecting portion 120 formed in a hollow shape (e.g., Figure 12B) may be used when the strength of the connecting portions 120 and 220 does not need to be strong, such as in footwear 100 or insole 200 where the user is expected to move with a relatively low exercise intensity, such as walking. This makes it possible to reduce the weight of the footwear 100 and insole 200 formed with the connecting portions 120 and 220 formed in a hollow shape.

[0167] Furthermore, for example, connecting portion 120 formed in the shape of a truncated cone or a variable cross-section cylinder (FIGS. 12D and 12E, respectively) may be used in cases where connecting portions 120 and 220 are required to be relatively strong and not tear, such as in footwear 100 or insole 200 where the user is expected to perform relatively high-intensity exercise such as running. In this case, for example, the cross-sectional areas of the portions of connecting portions 120 and 220 connected to identification information units 110 and 220 and the portions connected to footwear main body 102 and insole main body 202 can be particularly large, thereby increasing the strength of connecting portions 120 and 220.

[0168] 18A, provisional product shape data is then generated (S1810). In the shape data (first shape data) of the footwear main body 102, a portion of the shape data of the footwear main body 102 that corresponds to the determined initial position is trimmed, the shape of the identification information unit 110 is provided in the trimmed portion, and provisional shape data (provisional fourth shape data) of the footwear 100 is generated so that the identification information unit 110 is connected to the footwear main body 102 by the connection unit 120.

[0169] Next, the functionality of the footwear 100 modeled using the provisional shape data of the footwear 100 is evaluated (S1812). In this embodiment, the functionality of the footwear 100 modeled using the provisional shape data of the footwear 100 is evaluated by numerically analyzing the functionality in comparison with footwear modeled based on the shape data (first shape data) of the footwear main body 102 before the shape data of the identification information unit 110 and the connection unit 120 is added. For example, quantitative evaluation values ​​are calculated for multiple functions of the footwear 100, and these functions are compared with footwear modeled based on the first shape data. Note that the functionality may include, for example, the cushioning, fit, breathability, stability, flexibility, and safety of the footwear 100.

[0170] In this embodiment, the evaluation of the functionality of the footwear 100 may also take into consideration the user's intended use of the footwear 100, since the functions required of the footwear 100 differ depending on the type of exercise performed by the user. The intended use of the footwear 100 may be the type of exercise performed by the user while wearing the footwear 100, such as running, basketball, walking, mountain climbing, tennis, soccer, etc. Furthermore, in the evaluation of functionality in this embodiment, the user's movement tendencies, user preferences, etc. may also be taken into consideration.

[0171] Next, the relative error for the functionality is calculated (S1814). For example, the relative error for one or more functions is calculated.

[0172] If the relative error is 10% or more, the position where the identification information unit 110 is provided is corrected (S1816). For example, the position is corrected to a position further from the heel toward the toes. In this embodiment, the position is corrected to, for example, the position shown in the following equation 1. For example, starting from n=1, if the relative error in the evaluation of functionality is 10% or more at the position set the first time (i.e., the initial position, which is 10% from the heel toward the toes as described above), the position is corrected to 10+10*1=20%.

[0173] Thereafter, the process returns to the step (S1808) of generating the shape data (third shape data) of the connection portion 120, and then the above steps S1810 to S1814 are repeated until the relative error becomes less than 10%.

[0174] If the relative error is 10% or more, the molding angle of the connection portion 120 is subsequently evaluated based on information on the manufacturing method, etc. (S1818).

[0175] Here, with reference to FIG. 19A, the printing angle of the connection portion 120 in this embodiment will be described. FIG. 19A shows an enlarged view of the identification information structure 212-g1, each connection portion 220, and a portion (the lower right portion in FIG. 10C) of the three-dimensional lattice structure LS described above with reference to FIG. 10C. In this embodiment, the printing angle refers to the angle between the connection portion 120 and the side 112s to which the connection portion 120 is connected in the identification information structure 112. For example, as shown in FIG. 19A, the printing angle of the connection portion 120-1 and the printing angle of the connection portion 120-2 are the angle De1 between the connection portion 120-1 and the side 112s1 of the identification information structure 212 and the angle De2 between the connection portion 120-2 and the side 112s2 of the identification information structure 212.

[0176] 19A, the shape angle is determined and evaluated. In this embodiment, for example, it is evaluated whether or not there are any connecting portions 120 whose shape angle is 90° or less.

[0177] If there is a connection portion 120 whose shape angle is 90° or less, the connection portion 120 is deleted (S1820). For example, as shown in Fig. 19B, a connection portion 120-1 whose shape angle De1 is 90° or less is deleted.

[0178] After the connection portions 120-1 whose modeling angle De1 was 90° or less are deleted, the process proceeds to S1822, where product shape data (fourth shape data in this embodiment) is generated (S1822). Note that, if there are no connection portions 120 whose modeling angle is 90° or less in S1818, the process proceeds to S1822 without deleting the connection portions 120. That is, based on the shape data of the footwear main body 102 (first shape data in this embodiment), the shape data presenting the identification information (second shape data in this embodiment), and the shape data of the connection portions 120 (third shape data in this embodiment), shape data of the footwear 100 in which the identification information portion 110 is provided at the formation position corrected by the connection portions 120 (fourth shape data in this embodiment).

[0179] Next, the generated shape data is output (S1824).

[0180] As a result of the above, shape data of the footwear 100 having the identification information section 110 and the connection section 120 is generated, taking functionality and design into consideration.

[0181] Next, another example of the process for generating shape data for footwear 100 executed in this embodiment will be described with reference to Fig. 19C. The process for generating shape data for footwear 100 shown in Fig. 19C differs from the process for generating shape data for footwear 100 described above with reference to Fig. 18A in that, for example, the process for determining the position at which identification information unit 110 is to be built and the process for determining the minimum thickness of the equipment used to shape footwear 100 are performed in parallel.

[0182] 19C, first, information related to the product is input (S1902). In this embodiment, similar to S1662 (FIG. 16C), the information related to the product may include, for example, information on the type of product, information on the usage mode (information on the user's movement or tendency of the user's movement), information on the equipment used, and identification information to be presented by the identification information unit 110. For example, the information on the type of product may be information that the product is a sandal, the information on the usage mode may be information that the forefoot of the user is in contact with the ground when using the footwear 100, and the information on the equipment used may be information that the user is a 3D printer. Furthermore, the user may input, for example, a two-dimensional code image as identification information to be presented by the identification information unit 110.

[0183] Next, product determination (S1904), determination of built-in location based on movement trends (S1906), determination of minimum thickness of device used (S1908), and generation of shape data for identification information section (S1910) may be performed simultaneously in parallel, for example, as in S1664, S1666, S1668, and S1670 (FIG. 16C), respectively.

[0184] Next, provisional shape data (provisional fourth shape data) of the footwear 100 is generated using the method described above with reference to S1810, S1812, S1814, and S1816 (Figure 18A), etc., and the functionality of the footwear 100 formed using the generated provisional shape data of the footwear 100 is evaluated.Based on the results of the functionality evaluation, the built-in position of the identification information unit 110 is corrected as necessary, and shape data (third shape data) of the connection unit 120 is regenerated (S1912).

[0185] Next, unnecessary connecting portions 120 are deleted based on the evaluation results of the modeling angles of the connecting portions 120 by the methods described above with reference to S1818 and S1820 (FIG. 18A) and FIGS. 19A and 19B (S1914).

[0186] Next, similarly to S1822 and S1824 (FIG. 18A), product shape data is generated (S1916), and then the generated shape data is output (S1918).

[0187] In addition, the product determination (S1904), the determination of the built-in position based on the movement tendency (S1906), the determination of the minimum thickness of the equipment to be used (S1908), and the generation of shape data for the identification information section (S1970) may all be executed in parallel, or only some of them may be executed in parallel.

[0188] The above method also generates shape data for footwear 100 having identification information section 110 and connection section 120, taking functionality and design into consideration.

[0189] In this embodiment, the building angles De1 and De2 are evaluated as described above. At this time, in the manufacturing method for footwear 100 according to this embodiment, generating the fourth shape data includes measuring the connection angle (building angle De1 and building angle De2) of connection portion 120 relative to identification information section 110 at the position where connection portion 120 is connected to identification information section 110, determining whether the connection angle is equal to or less than a threshold angle (e.g., 90°), and deleting connection portion 120 from the fourth shape data if the connection angle is equal to or less than the threshold angle.

[0190] In the shape data generation process described with reference to FIGS. 16A to 16C, 18A and 18B, and 19A to 19C, the influence of the identification information unit 110 on the functionality and shapeability of the footwear 100 provided with the identification information unit 110 has been primarily considered. However, instead of or in addition to the functionality and shapeability, the readability of the identification information unit 110 may also be evaluated. That is, the readability of the identification information units 110 and 210 may be evaluated using the method for reading the identification information units 110 and 210 according to the present embodiment described above with reference to FIG. 14. For example, the evaluation may be based on whether or not the identification information presented by the identification information units 110 and 210 can be correctly read. If the identification information presented by the identification information units 110 and 210 cannot be correctly read, for example, the positions at which the identification information units 110 and 210 are provided may be changed in the shape data of the footwear 100 or insole 200 to be formed.

[0191] Furthermore, the manufacturing process for the body worn products 100 and 200 according to this embodiment is not limited to the method described above, and for example, the shapeability, functionality, and readability may be evaluated in an order different from that of the above-described exemplary embodiment. That is, the manufacturing method for the body worn products 100 and 200 according to this embodiment (the manufacturing method for the footwear 100 and the insole 200) may include checking the influence of the identification information units 110 and 210 on the shapeability of the footwear 100 and the insole 200, checking the influence of the identification information units 110 and 210 on the functionality of the footwear 100 and the insole 200, and checking whether the identification information presented by the identification information units 110 and 210 can be read. Furthermore, in the manufacturing method for the body worn items 100 and 200 according to this embodiment, if the effect on the shapeability of the footwear 100 and insole 200 does not satisfy predetermined conditions, if the effect on the functionality of the footwear 100 and insole 200 does not satisfy predetermined conditions, or if the identification information presented by the identification information units 110 and 210 cannot be read, the shape of the identification information units 110 and 210 may be changed, and the shape data (fourth shape data) of the footwear 100 and insole 200 may be updated based on the shape data (first shape data) of the footwear main body 102 and the insole main body 102 and the shape data (second shape data) of the changed identification information units 110 and 210.

[0192] In the manufacturing method of the body worn articles 100 and 200 according to the present embodiment (the manufacturing method of the footwear 100 and the insole 200), the generation process of the shape data (fourth shape data) of the footwear 100 and the insole 200 may be executed by, for example, a computer used as a shape data generating device. For example, a program for executing the shape data generation process is stored in a storage device included in the computer, and the processor included in the computer executes the program stored in the storage device included in the computer, thereby realizing the above-mentioned shape data generation process.

[0193] The program can be stored in a storage medium, which may be a non-transitory computer-readable medium. The non-transitory storage medium is not particularly limited, and may be, for example, a USB memory or a CD-ROM.

[0194] [Hardware configuration of the shape data generation device] Next, an example of a hardware configuration in which the shape data generating device is realized by a computer 800 will be described with reference to Fig. 20. Fig. 20 is a diagram showing an example of a hardware configuration of the computer 800.

[0195] As described below, the shape data generation device 800 according to this embodiment includes a memory for storing information (e.g., programs and various data) and a processor that operates based on the information stored in the memory. The functions of each unit of the processor may be implemented by individual hardware components, or may be implemented by integrated hardware components. The processor may be, for example, a CPU. However, the processor is not limited to a CPU; various types of processors, such as a graphics processing unit (GPU) or a digital signal processor (DSP), may also be used. The processor may also be an ASIC hardware circuit. The memory may be, for example, a semiconductor memory such as a static random access memory (SRAM) or a dynamic random access memory (DRAM), a register, a magnetic storage device such as a hard disk drive, or an optical storage device such as an optical disk drive. For example, the memory stores computer-readable instructions, and the functions of each unit of the shape data generation device are realized by the processor executing these instructions. The instructions may be instructions from an instruction set constituting a program, or instructions that instruct the hardware circuit of the processor to operate.

[0196] As shown in FIG. 20, a computer 800 includes, for example, a processor 802, a memory 804, a storage device 806, an input I / F unit 808, a data I / F unit 810, a communication I / F unit 812, and a display device 814.

[0197] Computer 800 may be, for example, a server computer, a personal computer (e.g., desktop, laptop, tablet, etc.), a media computing platform (e.g., cable, satellite set-top box, digital video recorder, etc.), a handheld computing device (e.g., PDA, email client, etc.), or any other type of computing or communications platform.

[0198] The processor 802 is a control unit that controls various processes in the computer 800 by executing programs stored in the memory 804 .

[0199] The memory 804 is a storage medium such as a RAM (Random Access Memory), etc. The memory 804 temporarily stores the program code of the program executed by the processor 802 and data required when the program is executed.

[0200] The storage device 806 is a non-volatile storage medium such as a hard disk drive (HDD), flash memory, etc. The storage device 806 stores an operating system and various programs for realizing the above-mentioned configurations.

[0201] The input I / F unit 808 is a device for receiving input from a user. The input I / F unit 808 is, for example, a keyboard, a mouse, a touch panel, various sensors, a wearable device, etc. The input I / F unit 808 may be connected to the computer 800 via an interface such as a USB (Universal Serial Bus).

[0202] The data I / F unit 810 is a device for inputting data from outside the computer 800. The data I / F unit 810 is, for example, a drive device for reading data stored in various storage media. The data I / F unit 810 may be provided outside the computer 800. When the data I / F unit 810 is provided outside the computer 800, the data I / F unit 810 is connected to the computer 800 via an interface such as a USB.

[0203] The communication I / F unit 812 is a device for performing data communication via a network such as the Internet, either wired or wirelessly, with a device external to the computer 800. The communication I / F unit 812 may be provided outside the computer 800. When the communication I / F unit 812 is provided outside the computer 800, the communication I / F unit 812 is connected to the computer 800 via an interface such as a USB.

[0204] The display device 814 is a device for displaying various types of information. The display device 814 is, for example, a liquid crystal display, an organic EL (Electro-Luminescence) display, a display of a wearable device, or the like. The display device 814 may be provided outside the computer 800. When the display device 814 is provided outside the computer 800, the display device 814 is connected to the computer 800 via, for example, a display cable. Furthermore, when a touch panel is adopted as the input I / F unit 808, the display device 814 may be configured as an integral part of the input I / F unit 808.

[0205] The program for generating shape data according to this embodiment, or a part thereof, may be stored in a computer-readable storage medium such as the storage device 806 and provided. The storage medium storing the program may be a non-transitory computer-readable medium. The non-transitory storage medium is not particularly limited, and may be, for example, a USB memory, a CD-ROM, or the like.

[0206] Alternatively, the program for generating the shape data according to this embodiment may be provided from outside the shape data generating device via a communication network to which the shape data generating device is connected.

[0207] Note that these physical configurations are merely examples and do not necessarily have to be independent. For example, the shape data generation device according to this embodiment may include an LSI (Large-Scale Integration) in which the processor 802 and the storage device 806 are integrated.

[0208] Furthermore, the shape data generating device is not limited to the above-described configuration, and may be configured such that some or all of the functions of the shape data generating device are executed by another information processing device.

[0209] In the above-described embodiments, the identification information units 110 and 210 are provided inside the footwear 100 and the insole 200. However, in other embodiments, the identification information units 110 and 210 may be provided, for example, on the outer surfaces of the footwear 100 and the insole 200. When the identification information unit 110 is provided on the outer surface of the footwear 100, the identification information unit 110 may be provided, for example, in a manner that avoids a portion of the footwear main body 102 that comes into contact with the ground or the foot. In other words, the identification information unit 110 may be provided in a portion of the footwear 100 other than a portion of the footwear 100 that comes into contact with the ground or a portion of the footwear 100 that comes into contact with the foot of the user when the footwear 100 is in use.

[0210] If the identification information unit 110 is provided on the bottom surface of the footwear 100, there is a possibility that the identification information unit 110 will rub against the ground and wear away when the footwear 100 is used. Furthermore, if the identification information unit 110 is provided on the outer surface of the footwear body 102 corresponding to the portion that comes into contact with the user's leg, there is a possibility that the identification information unit 110 will wear away due to contact with the user's leg. As a result, there is a possibility that the identification information presented by the identification information unit 110 will become unrecognizable due to damage, loss, or the like.
