Description

[Technical Field]

[0001] The present disclosure relates to body wear and footwear manufacturing methods. [Background technology]

[0002] Conventionally, manufactured and sold products are assigned identification information to identify the product. By using the identification information, it is possible to manage, for example, the product's manufacturing information, design information, shipping and sales information, and even its usage history and failure history.

[0003] In recent years, it has become possible to manufacture products using three-dimensional additive manufacturing, and products tailored to individual user specifications are now being manufactured and sold. When manufacturing products using three-dimensional additive manufacturing, after the product is formed, there are processes such as removing support members, separating excess material, cleaning, drying, UV irradiation, heat curing, polishing and coating, as well as quality confirmation. 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 provides the product desired by the user by accepting customization by the user for 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 purchase location, 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 inside of the product (three-dimensional object) to be provided, thereby ensuring the traceability of the product (three-dimensional object). [Prior art documents] [Patent documents]

[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, an object of the present disclosure is to provide a method for manufacturing body wear and footwear that can properly manage products using identification information while maintaining the original appearance and functionality of the products. [Means for solving the problem]

[0008] One aspect of the present disclosure provides a body-worn product, the body-worn product comprising: a body-worn product main body; and an information display unit that is simultaneously molded with the body-worn product main body and has a connecting portion that connects to the body-worn product main body. The information display unit includes identification information that identifies the body-worn product main body.

[0009] According to this aspect, the information display unit is simultaneously molded together with the body-worn item main body, has a connecting portion that connects to the body-worn item main body, and further includes identification information that identifies the body-worn item main body, so that the body-worn item can be properly managed using the identification information while maintaining its original appearance and functionality.

[0010] One aspect of the present disclosure provides a footwear manufacturing method for manufacturing footwear made of a three-dimensional additively manufactured object. The footwear manufacturing method includes simultaneously molding, on a platform, an information display unit having a connecting portion that connects to the footwear main body, together with the footwear main body. The information display unit is molded to include identification information that identifies the footwear main body, and / or is printed or processed to include the identification information after the information display unit is molded.

[0011] According to this aspect, the information display unit has a connecting portion that connects to the footwear main body and is simultaneously molded with the footwear main body. The information display unit is molded to include identification information that identifies the footwear main body, and / or is printed or processed to include the identification information after the information display unit is molded, so that the footwear can be properly managed using the identification information while maintaining the original appearance and functionality of the footwear.

[0013] Preferred embodiments of the present disclosure will be specifically described below with reference to the accompanying drawings. Note that the embodiment described below is merely a specific example for implementing the present disclosure and is not intended to limit the scope of the present disclosure. Furthermore, to facilitate understanding of the description, the same components in each drawing will be denoted by the same reference numerals whenever possible, and duplicate descriptions may be omitted.

[0014] <One embodiment> [Footwear and insole configuration] 1 is a perspective view showing an outline of footwear 100 (body-worn item) according to an embodiment of the present disclosure. As shown in FIG. 1, footwear 100 (body-worn item) includes a footwear body 110 (body-worn item body), a sign 120 (information display unit), and a connecting unit 130.

[0015] Footwear 100 is manufactured by using a three-dimensional lamination method to form footwear body 110, markings 120, and connecting portion 130. Examples of the manufacturing method include a material extrusion method called FDM (Fused Deposition Modeling), a photolithography method called DLP (Digital Light Processing), a stereolithography method called SLA (Stereolithography), an LCD (Liquid Crystal Display), a powder bed fusion method called SLM (Selective Laser Melting), an EBM (Electron Beam Melting), and an inkjet method, and an appropriate method may be used depending on the shape, function, design, and material of footwear body 110 to be manufactured.

[0016] 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.

[0017] 2 is a perspective view showing an outline of an insole 200 (body-worn item) according to one embodiment of the present disclosure. As shown in FIG. 2, the insole 200 (body-worn item) includes an insole body 210 (body-worn item body), a sign 220 (information display section), and a connecting section 230.

[0018] The insole 200 is manufactured by forming the insole body 210, the markings 220, and the connecting portion 230 using a three-dimensional lamination method.

[0019] The footwear main body 110 and the insole main body 210 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.

[0020] The marker 120 is simultaneously formed together with the footwear main body 110. Here, "simultaneously" includes the period during which the footwear main body 110 is formed, and "simultaneous formation" means that the footwear main body 110 and the marker 120 are completed together in a single formation. The marker 120 includes identification information that identifies the footwear main body 110.

[0021] The connecting portion 130 connects the footwear body 110 and the marker 120 together.

[0022] The markings 120 and the connecting portions 130 may be made of the same material as the footwear main body 110, or may be made of a different material and / or a different color than the material as the footwear main body 110.

[0023] Similarly, the markings 220 are simultaneously formed together with the insole body 210 and include identification information that identifies the insole body 210. The connecting portion 230 connects the insole body 210 and the markings 220. The markings 220 and the connecting portion 230 may be formed from the same material as that used to form the insole body 210, or may be formed from a different material and / or a different color than that used to form the insole body 210.

[0024] [Identification information] 3 is a diagram illustrating information managed in footwear 100 or insole 200 according to an embodiment of the present disclosure. As shown in FIG. 3, footwear and insoles manufactured using the three-dimensional layering method are delivered to a user through steps S110 to S200.

[0025] In step S110, the user may, for example, visit a store equipped with a 3D scanner and scan their footprint, or scan their footprint at home using a smartphone. Here, customer information, including the user's name, address, contact information, age, gender, and purchase history, as well as the user's footprint, the scan date and time, and the scan data, are recorded. Additionally, physical information that may affect changes in the product due to use may also be recorded. For example, the information may include the user's height, weight, gender, the size or shape of the body part corresponding to the product, and information about movement habits. Information about movement habits may include, for example, information about walking or running habits (e.g., cadence, 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, and foot shape.

[0026] Furthermore, when a user orders a product, product information such as product type, product shape, and color may be recorded. For example, the user inputs the product type (model), product shape, and 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 has actually ordered and a product that the user is considering ordering). 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 for ordering, and may also include preference information including the user's preferred product type (model), product shape, and color.

[0027] 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.

[0028] In step S120, a homologous modeling process of the footprint of the user is performed based on the scan data acquired in step S110. Here, homologous model data is generated as a three-dimensional image of the footprint of the user.

[0029] In step S130, footwear or insoles that fit the user's foot shape are designed based on the homologous model data generated in step S120. 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. 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 insoles, shoes, or sandals, for example. Use may be information about a specific sport or activity, such as running, walking, soccer, or tennis. Last information may be information about the last on which the product was designed, particularly whether an existing product last was used or whether a last tailored to the user's foot shape was used.

[0030] In step S140, footwear or insoles are modeled using a three-dimensional additive manufacturing method based on the 3D model data generated in step S130. Here, information on the modeling date and time, materials used, modeling conditions, modeling location, device serial number, and modeling technician is recorded. The materials used are information on the materials used to model the footwear or insoles using a three-dimensional additive manufacturing method, and may include, for example, information on the type, weight, and material lot of the material. The modeling conditions may include information on the three-dimensional additive manufacturing method (modeling device) used to model the footwear or insoles, the production lot, and the like.

[0031] In step S150, post-processing is performed on the footwear or insole printed in step S140. Post-processing may include, for example, peeling the footwear or insole printed in step S140 from the platform, cleaning off excess resin, post-curing, removing support material, polishing, and coating. Information about the date and time of post-processing, process time, processing conditions, and processing personnel is 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.

[0032] In step S160, a quality check is performed on the footwear or insole post-processed in step S150, where information such as the date and time of the check, information about the person in charge, the quality inspection results, the weight, and other information about the product characteristics are recorded.

[0033] The information recorded in steps 130, 140, 150, and 160 may be information automatically acquired from the device that performed the process, or may be information entered by the operator.

[0034] In step S170, the footwear or insoles that have undergone the quality check in step S160 are shipped, and the shipping date and time are recorded.

[0035] In step S180, the footwear or insoles shipped in step S170 are received by, for example, the purchaser, and the date and time of receipt is recorded.

[0036] In step S190, the user uses the footwear or insole received in step S180. 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 via, for example, 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, this may include information regarding the frequency of use of the product by the user, the usage time, the usage intensity, the usage distance, and the road surface condition at the time of use (e.g., concrete, dirt, grass, tartan, 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 via, for example, 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, and intensity of walking or running.

[0037] In step S200, the user discards the footwear or insole used in step S190. 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.

[0038] In this way, the information and data generated, acquired, and recorded in each series of processes are managed by being linked to identification information (control number) corresponding to the user's footwear main body 110 or insole main body 210. In other words, information including customer information and manufacturing information (manufacturing process information) related to the footwear main body 110 or insole main body 210 is managed collectively using the identification information (control number). This ensures traceability, allowing information related to the footwear main body 110 or insole main body 210 to be tracked based on the identification information (control number).

[0039] Because the identification information (control number) is included in the mark 120 (mark 220) formed together with the footwear main body 110 (insole main body 210), there is an extremely low possibility of discrepancies occurring in the correspondence between the identification information (control number) and the footwear main body 110 (insole main body 210). For example, based on the identification information (control number), users and manufacturers can easily confirm the above-mentioned customer information and manufacturing information (manufacturing process information) for the footwear main body 110 (insole main body 210) corresponding to the identification information (control number).

[0040] The identification information (control number) may be assigned, for example, when the 3D model data is generated in step S130. Alternatively, the identification information (control number) may be assigned in step S110 or step S120 before the sign 120 (sign 220) is formed. If the identification information (control number) is assigned in step S110, the product and the customer are linked, making it possible to link who made what footprint and what model. If the identification information (control number) is assigned in step S120, a model is created from the footprint at that time, making it possible to understand in step S130 why this model was chosen. If the identification information (control number) is assigned in step S130, the manufactured model is linked to the product.

[0041] 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, or unique shapes that conform to any rules. Furthermore, the identification information may be composed not only of a control number, but also of the actual size of the footwear or insole, the user's name, etc. Furthermore, the identification information (control number) may hold, for example, the evaluation results of environmental indicators obtained by an environmental impact assessment system. Environmental indicators may be derived based on, for example, at least one of carbon dioxide emissions, land and soil impacts, fossil fuel use, mineral and metal use, water use, freshwater ecosystem impacts, nutrient emissions to freshwater systems, acidification impacts, nutrient emissions to marine systems, nutrient emissions to terrestrial ecosystems, photochemical ozone emissions, respiratory impacts, radioactive emissions, carcinogenic emissions, non-carcinogenic toxic and deleterious emissions, and ozone depletion impacts.

[0042] [Connection between the insole body and the sign] Next, the connecting portion between the insole main body 210 and the marker 220 will be described in detail using the insole main body 210 and the marker 220 as an example. The insole main body 210 and the marker 220 may be connected in a physically continuous state, or may be connected in a string-like state.

[0043] The physically continuous state means that a part of the insole body 210 and a part of the marker 220 are continuous and directly connected. In other words, the marker 220 includes a connecting portion that is the part that is connected to the insole body 210.

[0044] The state of being connected in a string-like manner means that the insole body 210 and the marker 220 are connected via a string-like connecting part that is thinner than the marker 220. A specific example will be described below.

[0045] FIG. 4A is a diagram showing how the marker 220 is connected to the insole body 210 via multiple (here, two) connecting portions 230A. As shown in FIG. 4A, the two connecting portions 230A are configured to connect the heel portion of the insole body 210 to both ends of the marker 220, respectively. While it is possible to connect the insole body 210 and the tag marker 220 using a single connecting portion, the provision of multiple connecting portions 230A reduces the possibility of the insole body 210 and the tag marker 220 becoming separated from each other after molding and before delivery to the user. Note that, although two connecting portions 230A are shown here as an example of multiple connecting portions, three or more connecting portions may be used. Furthermore, the connecting portions 230A do not have to be independent of each other. For example, the connecting portions 230A may have a truss-like structure, a bifurcated structure, a three-dimensional mesh-like structure, or the like.

[0046] Fig. 4B is a diagram showing how the marker 220 is connected to the insole body 210 via two connecting parts 230B. As shown in Fig. 4B, the two connecting parts 230B are configured to connect the heel part of the insole body 210 to side parts of the marker 220 that are closer to the center than the end parts. By arranging the two connecting parts 230B at the side parts rather than at the end parts (corners) of the marker 220, the possibility of the two connecting parts 230B becoming detached at the connection parts with the marker 220 is reduced.

[0047] 4C is a diagram showing how the marker 220 is connected to the insole body 210 via two connecting portions 230C. As shown in FIG. 4C, the two connecting portions 230C are configured to connect the heel portion of the insole body 210 to both ends of the marker 220, respectively. The two connecting portions 230C are formed to taper toward the heel portion of the insole body 210, so that when removing the marker 220 from the insole body 210, it is easy to cut it off at the heel portion of the insole body 210, and further, it is difficult to leave any trace of the cutting on the insole body 210, or the trace can be made small. In other words, the original appearance and functionality of the insole body 210 can be maintained.

[0048] 4D is a diagram showing how the marker 220 is connected to the insole body 210 via two connecting portions 230D. As shown in FIG. 4D, the two connecting portions 230D are configured to connect the heel portion of the insole body 210 to both ends of the marker 220, respectively. The two connecting portions 230D are formed thinner than the average of the connecting portions 230D near the insole body 210. Therefore, when removing the marker 220 from the insole body 210, it is easy to cut off the marker 220 at the heel portion of the insole body 210, and further, it is difficult to leave any trace of the cutting on the insole body 210, or the trace can be made small. In other words, the original appearance and functionality of the insole body 210 can be maintained. Furthermore, the two connecting portions 230D are formed thinner than the average of the connecting portions 230D near the insole body 210, and are therefore easier to shape and adjust the connecting angle than the two connecting portions 230C that are gradually tapered as described above.

[0049] 4A to 4D are preferably formed from the same material as insole body 210. Even if traces of connecting parts 230A to 230D that have been cut from insole body 210 remain on insole body 210, the impact on the original appearance and functionality of insole body 210 can be reduced.

[0050] The connecting portions 230A to 230D are not limited to being made of the same material as the insole body 210, and may be made of a different material, for example, as long as it is difficult to leave any trace of having been cut from the insole body 210, or the trace can be made small.

[0051] Furthermore, it is preferable that the marker 220 is formed from the same material as the insole body 210. Using a three-dimensional lamination method, it can be easily formed simultaneously with the insole body 210, and further, when the marker 220 is stored in the insole body 210 as described below, the marker 220 can be assimilated into the insole body 210, reducing the sense of incongruity.

[0052] On the other hand, the marker 220 is not limited to being made of the same material as the insole body 210, and may be made of a different material, for example, if the marker 220 can be properly stored in the insole body 210, or if the marker 220 is managed without being stored in the insole body 210.

[0053] Furthermore, the marker 220 (connecting portions 230A to 230D) may be shaped in the same color as the insole body 210 or in a different color, as long as this reduces the sense of incongruity when storing the marker 220 in the insole body 210 as described below.

[0054] Fig. 5 is a diagram for explaining the positions at which the connecting parts 230 are arranged in the insole body 210. As shown in Fig. 5, in the insole body 210 configured with a lattice structure, there are positions that are intersections of the lattice structure (for example, points P1 to P4, etc.) and positions on the beams of the lattice structure (for example, points Q1 to Q4, etc.).

[0055] 4A to 4D, the connection points of connecting portions 230A to 230D with insole body 210 may be at positions on the beams of the lattice structure that are not intersections of the lattice structure (for example, points Q1 to Q4), and are preferably at positions that are intersections of the lattice structure that make up insole body 210 (for example, points P1 to P4). If the connection points are at positions that are intersections of the lattice structure that make up insole body 210 (for example, points P1 to P4), it is possible to reduce the risk of the beams breaking when attempting to detach connecting portions 230A to 230D from insole body 210.

[0056] It is preferable that the connecting portions 230A to 230D as shown in FIGS. 4A to 4D can be easily cut when removing the marker 220 (including the connecting portions 230A to 230D) from the insole body 210 while preventing them from accidentally becoming detached, and the thickness of the connecting portions 230A to 230D may be, for example, 1 mm or more in diameter.

[0057] The connecting portions 230A to 230D as shown in FIGS. 4A to 4D may be, for example, cylindrical or prismatic, and are not limited to a particular shape, but may be configured to have different cross-sectional shapes depending on the insole body 210, for example.

[0058] FIG. 6A is a diagram showing a connecting portion 231A having a rectangular cross-sectional shape, FIG. 6B is a diagram showing a connecting portion 231B having a star-shaped cross-sectional shape, and FIG. 6C is a diagram showing a connecting portion 231C having a circular cross-sectional shape.

[0059] For example, the insole body 210 for walking uses a connecting part 231A with a rectangular cross-sectional shape as shown in FIG. 6A, the insole body 210 for running uses a connecting part 231B with a star-shaped cross-sectional shape as shown in FIG. 6B, and the insole body 210 for tennis uses a connecting part 231C with a circular cross-sectional shape as shown in FIG. 6C.

[0060] As described above, the marker 220 is cut out from the insole main body 210 and then managed. Here, in the connecting portions 231A to 231C shown in Figures 6A to 6C, the trace left on the insole main body 210 after the marker 220 is cut out from the insole main body 210 is different. In other words, after the marker 220 is cut out from the insole main body 210, the combination of the insole main body 210 and the marker 220 can be easily determined.

[0061] Specifically, if the user owns a plurality of insole bodies 210, the combination of the plurality of insole bodies 210 and the markers 220 cut out from each insole body 210 can be easily determined.

[0062] The (cross-sectional) shape of the connecting portion 230 may be specified or selected by the user when ordering the insole 200, or may be appropriately set by the manufacturer. Based on history information such as customer information and manufacturing information, if the order is from the same user, the connecting portion 230 may be manufactured so that it has a (cross-sectional) shape different from that of the connecting portion 230 of an insole 200 manufactured in the past.

[0063] [Storing signs] Next, we will explain how to manage the marker 220 cut out from the insole body 210. Since the identification information for identifying the insole body 210 is contained in the marker 220 that is shaped together with the insole body 210, it is important to properly manage the marker 220 cut out from the insole body 210.

[0064] 7A is a diagram showing a state in which a marker 220A is stored in an insole body 210 according to one embodiment of the present disclosure. As shown in FIG. 7A, the insole body 210 includes a storage section 211A, and the marker 220A is stored in the storage section 211A.

[0065] Specifically, the storage section 211A is formed by a recess on the surface of the insole body 210 so as to correspond to the shape of the marker 220A. After being removed from the insole body 210, the marker 220A is stored in the storage section 211A of the insole body 210 so as to fit into the recess.

[0066] 7B is a diagram showing how marker 220B is stored in insole main body 210 according to one embodiment of the present disclosure. As shown in FIG. 7B, insole main body 210 includes storage section 211B, and marker 220B is stored in storage section 211B.

[0067] Specifically, the storage section 211B is formed by a recess on the surface of the insole body 210 so as to correspond to the shape of the marker 220B. After being removed from the insole body 210, the marker 220B is stored in the storage section 211B of the insole body 210 by being inserted into the recess.

[0068] In this way, by storing the markers 220A, 220B cut out from the insole body 210 in the storage sections 211A, 211B provided in the insole body 210, it is possible to prevent the markers 220A, 220B from being lost and to properly manage the markers 220A, 220B corresponding to the insole body 210.

[0069] The location of the storage section for storing the marker 220 in the insole body 210 is not limited to the thickness portion of the side surface of the insole body 210 (storage section 211A) shown in Fig. 7A or the thickness portion of the heel of the insole body 210 (storage section 211B) shown in Fig. 7B. Furthermore, when the marker 220A is stored in the storage section 211A in the thickness portion of the side surface of the insole body 210 as shown in Fig. 7A, the insole body 210 may be used with the marker 220A stored therein, or may be used without the marker 220A stored therein. For example, when the insole body 210 is used with the marker 220A stored therein, it is preferable to prevent the marker 220A from slipping or coming off by using a hook-and-loop fastener and the fit of the storage section 211A and the marker 220A due to the concave-convex shape.

[0070] Since the insole body 210 is used by being placed inside the footwear, it is unlikely to be worn out by rubbing against the ground or by other external contact, and is used in a state of close contact with the sole of the user's foot and the footwear. That is, the insole body 210 may be provided with a storage section for storing the marker 220 on, for example, the top surface (surface in contact with the sole of the user's foot) and the bottom surface (surface in contact with the inside of the footwear).

[0071] However, it is preferable that the surface of the insole body 210 with the marker 220 stored in the storage section be flush. This ensures stability when the insole body 210 with the marker 220 stored in the storage section is placed inside the footwear, reducing the possibility of the user feeling uncomfortable when wearing the footwear. As a result, the original function of the insole body 210 can be ensured without being impaired.

[0072] 1, if a storage section is provided on the bottom surface of the footwear body 110, for example, the marker 120 stored in the storage section will rub against the ground and wear away. If the storage section is provided on the outer surface of the footwear body 110 corresponding to the instep, the marker 120 stored in the storage section may wear away due to contact with the outside. As a result, the identification information formed on the marker 120 may be damaged or lost, making it impossible to identify.

[0073] Furthermore, if a storage compartment is provided in a location on the footwear body 110 that is visually conspicuous, the marker 120 stored in the storage compartment will stand out, which may detract from the original appearance of the footwear body 110. Also, if the identification information formed on the marker 120 is conspicuous, this may lead to the leakage of personal information, etc.

[0074] Therefore, when a storage section is provided in the footwear main body 110, the position of the storage section is preferably in the thickness portion of the side surface, the thickness portion of the heel, or the inner surface of the footwear main body 110 (the surface that comes into contact with the instep of the user, the surface that comes into contact with the heel of the user, the surface that comes into contact with the sole of the user, etc.). However, it is preferable that the inner surface of the footwear main body 110 in which the marker 120 is stored in the storage section is flush to reduce any discomfort felt by the user when wearing the footwear main body 110.

[0075] Furthermore, when providing a storage section on the outer surface of the footwear main body 110 (including the thick portions of the sides and the thick portion of the heel), it is preferable to avoid at least the bottom surface where the marker 120 may be worn, and to adopt a position and method that does not impair the appearance of the footwear main body 110. Specifically, the marker 120 stored in the storage section may be configured so that the area exposed on the outer surface is small, or the color and pattern of the marker 120 exposed on the outer surface may be formed to match the color and pattern of the footwear main body 110.

[0076] The storage section provided in the footwear main body 110 (insole main body 210) may have a pocket-like structure capable of storing the marker 120 (220).

[0077] The footwear 100 (insole 200) is delivered to the user with the marker 120 (220) connected to the footwear main body 110 (insole main body 210), and the user removes the marker 120 (220) from the footwear main body 110 (insole main body 210). It is assumed that the user will manage the marker 120 (220), but this is not a limitation.

[0078] For example, before shipping the footwear 100 (insole 200), the manufacturer may remove the marker 120 (220) from the footwear main body 110 (insole main body 210) and store the marker 120 (220) at the manufacturer's side. In this case, information similar to or corresponding to the identification information included in the marker 120 (220) may be attached to the footwear main body 110 (insole main body 210) of the footwear 100 (insole 200) to be shipped.

[0079] [Sign Configuration] Next, the specific configuration of the marker will be described using the marker 220, which is formed simultaneously with the insole body 210, as an example.

[0080] Fig. 8 is a diagram showing an example of a sign 220 having a solid surface. As shown in Fig. 8, identification information is formed on one surface of the rectangular plate-shaped sign 220. Note that the surface on which the identification information is formed is not limited to one surface of the sign 220, and the identification information may be formed on two or more surfaces.

[0081] The identification information may be configured using a convex or concave shape on a solid surface. When using convex and concave shapes to configure identification information such as letters and symbols, the difference in level between the identification information portion represented by the letters and symbols and the base portion serving as the base is preferably, for example, 0.4 mm or more from the viewpoint of readability when visible to the naked eye, but may be smaller when read by a sensor. Furthermore, the size of the characters is preferably, for example, 1 mm square or more per character when considering visibility with the naked eye, but may be smaller when read by a sensor.

[0082] Furthermore, when a curved surface is formed on a solid surface, thickness may be provided in the normal direction to the curved surface, which makes it easier to ensure formability, and when identifying information such as letters and symbols is formed on the curved surface using convex and concave shapes, forming them in the normal direction to the curved surface can improve readability.

[0083] Furthermore, the sign 220 may have identification information such as letters and symbols formed by punching holes that penetrate from one surface of the square plate-shaped sign 220 to the opposite surface.

[0084] Furthermore, the identification information on the solid surface is not limited to being formed while the mark 220 is being shaped into a convex, concave, or hole shape, but may be formed, for example, by printing on the solid surface after the mark 220 is shaped. The printing method is not particularly limited, and may be, for example, laser engraving, inkjet printing, thermal transfer printing, pad printing, black light, embossing, cutting, or the like.

[0085] The shape of the sign 220 is not limited to a rectangular plate, but may be, for example, a circular, elliptical, oval, or other polygonal plate.

[0086] Furthermore, the dimensions of the marker 220 (the portion where the identification information is formed) need not be excessively large in terms of the amount of material used and the printing area, nor excessively small so that the necessary information can be written sufficiently. As described above, considering that the marker 220 will be stored in the storage section of the insole body 210, the marker 220 is smaller than the insole body 210, and may be, for example, preferably about 10 to 200 mm in length, 5 to 50 mm in width, and 2 to 50 mm in thickness, or more preferably about 30 to 70 mm in length, 10 to 30 mm in width, and 5 to 15 mm in thickness.

[0087] 9A is a diagram showing an example in which corresponding markers 220L and 220R are provided on the left and right insole bodies 210L and 210R, respectively. As shown in FIG. 9A, a left foot marker 220L is connected to the left insole body 210L, and a right foot marker 220R is connected to the right insole body 210R.

[0088] Naturally, the shapes of a user's right and left feet are different, and the shapes are not necessarily symmetrical. For example, the sizes (length and width) may be different, they may be used for different sports, or they may have characteristics that correspond to different walking styles. If the insole 200 is made to order, the left and right insole bodies 210L and 210R are manufactured to fit the left and right feet, respectively. That is, different identification information may be assigned to the left and right insole bodies 210L and 210R depending on such a user.

[0089] Also, one piece of identification information may be given to the left and right insole bodies 210L and 210R so that they can be managed as one pair.

[0090] 9B is a diagram showing an example in which corresponding markers 221L and 221R are provided on the left and right insole bodies 210L and 210R, respectively. As shown in FIG. 9B, a left foot marker 221L is connected to the left insole body 210L, and a right foot marker 221R is connected to the right insole body 210R.

[0091] As described above, the left and right insole bodies 210L and 210R are manufactured to fit the left and right feet, respectively. Then, after removing the markers 221L and 221R connected to the left and right insole bodies 210L and 210R, respectively, the markers 221L and 221R may be combined to form a single piece of identification information. That is, the markers 221L and 221R are formed as a pair. Here, the "pair" refers to the combination of the markers 221L and 221R, as shown in FIG. 9B, where the shapes of the connected portions of the markers 221L and 221R match to form a single piece of identification information, or the colors and patterns of the connected portions match to form a single piece of identification information. Furthermore, the single piece of identification information may be formed by a conceptual connection based on the content written on the markers 221L and 221R.

[0092] [Footwear (insole) manufacturing method] Next, a footwear manufacturing method will be described in which a footwear main body and a marker formed together with the footwear main body using a material for forming the footwear main body are manufactured using a three-dimensional layering method. Here, a detailed description will be given using an insole main body 210 and a marker 220 as examples.

[0093] Fig. 10A is a diagram showing the positional relationship between the insole main body 210 and the marker 220 formed by stacking them on the platform P. As shown in Fig. 10A, the bottom surface of the insole main body 210 and the bottom surface of the marker 220 are formed at the same height.

[0094] Fig. 10B is a plan view showing the positional relationship between the insole body 210 to be formed and the marker 220. As shown in Fig. 10B, the insole body 210 and the marker 220 may be formed separately as separate parts, and the marker 220 may be formed around the insole body 210, for example, at one of positions 22P1 to 22P6.

[0095] As described above, the position at which the marker 220 is formed is not particularly limited, but if the insole main body 210 and the marker 220 are formed in a state in which they are connected via the connecting part 230, it is preferable that the insole main body 210 and the marker 220 are formed in close proximity to each other. For example, if one end of the connecting part 230 is disposed at the heel of the insole main body 210 and the other end of the connecting part 230 is connected to the marker 220, it is preferable that the marker 220 be formed in the vicinity of the heel of the insole main body 210 (position 22P1). This allows the amount of material used for the connecting part 230 to be reduced while avoiding making the shape of the connecting part 230 complex.

[0096] The marker 220 may also be manufactured separately from the insole body 210, for example, by using a support part added to the model during modeling. Support parts are necessary depending on the structure of the product to be modeled, and may be attached to the outside of the model to ensure stable modeling. They are removed from the final product and often become waste. This allows for effective use of materials that would normally be discarded.

[0097] 11A is a diagram showing the position at which the connecting portion 230 that connects the insole main body 210 and the marker 220 is formed on the platform P. As shown in Fig. 11A, the connecting portion 230 is formed at the same height as the bottom surfaces of the insole main body 210 and the marker 220. As a result, the connecting portion 230 is stably formed while reducing the distance between the insole main body 210 and the marker 220 and reducing the amount of material.

[0098] 11B is a diagram showing the position of connecting portion 230 that connects insole body 210 and marker 220, where connecting portion 230 is shaped at an angle relative to platform P. As shown in FIG. 11B, connecting portion 230 is shaped away from platform P and does not contact platform P.

[0099] When the connecting portion 230 is formed away from the platform P, the distance between the connecting position of the connecting portion 230 and the insole main body 210 and the connecting position of the connecting portion 230 and the marker 220 relative to the platform P is different. In other words, the connecting portion 230 is formed not parallel to the platform P but at an angle. This angle is preferably 30 degrees or more to ensure formability.

[0100] As a result, the connecting portion 230 does not need to be peeled off from the platform P, and the entire insole 200 (insole body 210, marker 220, and connecting portion 230) is structured to be easily peeled off from the platform P.

[0101] Furthermore, the sign 220 may also be structured so as to be easily peeled off from the platform P.

[0102] 12A is a diagram showing a sign 220 formed of a solid 221 and a lattice structure 222. As shown in Fig. 12A, the sign 220 has the lattice structure 222. For example, the sign 220 is formed so that the surface of the lattice structure 222 is in contact with the platform P, thereby making it possible to reduce the contact area between the sign 220 and the platform P. As a result, the sign 220 can be easily peeled off from the platform P.

[0103] Furthermore, the markings 220 (solid 221 and lattice structure 222) may be formed simultaneously with the insole body 210 using the same material and structure. This allows the markings 220 to blend in with the insole body 210 without impairing its appearance when stored in the storage sections 211A, 211B of the insole body 210, for example.

[0104] Furthermore, for testing the insole body 210, it is possible to use the markings 220 (solid 221 and lattice structure 222) formed from the same material as the insole body 210. For example, the solid 221 can be used for discoloration, durability tests, and mechanical property tests, and the lattice structure 222 can be used for tack evaluation and compression tests.

[0105] 12B is a diagram showing a sign 220 formed of a solid 221 and a hollow structure 223. As shown in FIG. 12B, the sign 220 has a hollow structure 223. For example, the sign 220 is formed so that the surface of the hollow structure 223 is in contact with the platform P, thereby making it possible to reduce the contact area between the sign 220 and the platform P. As a result, the sign 220 can be easily peeled off from the platform P.

[0106] 13 is a diagram showing an example of a procedure for combining a model of the insole main body 210 and a model of the marker 220 (including identification information) to form the insole 200. As shown in FIG. 13, a model of the insole main body 210 is acquired (step S210), and the model is stored as 3D data of the insole main body 210 (step S220). A model of the marker 220 to which identification information has been assigned is then acquired (step S230). Then, based on these, modeling data for the insole 200 is generated (step S240), and the insole 200 is modeled based on the modeling data (step S250).

[0107] This eliminates the need to generate a model of the insole body 210 each time, and allows for efficient manufacturing, for example, when the model of the insole body 210 is used repeatedly or when multiple identical insole bodies 210 are manufactured.

[0108] [Effects of one embodiment] According to the footwear 100 (insole 200) and footwear manufacturing method (insole manufacturing method) according to an embodiment of the present disclosure, the marker 120 (marker 220) is simultaneously formed together with the footwear main body 110 (insole main body 210) using a three-dimensional lamination method. The insole main body 210 and the marker 220 are connected via a connecting portion 230 when formed, and the marker 220 includes identification information, making it extremely unlikely that a discrepancy will occur in the association between the identification information (control number) and the insole main body 210. The marker 220 can be removed from the insole main body 210 and appropriately stored in storage portions 211A, 211B provided in the insole main body 210, allowing the marker 220 to be managed without being lost while maintaining the original appearance and functionality of the insole main body 210.

[0109] In this embodiment, the connecting portion 230 connects the insole main body 210 and the marker 220 by being directly adhered to the insole main body 210 and the marker 220, but this is not limited to this.

[0110] FIG. 14 is a diagram showing how the marker 220 is connected to the insole body 210 by a loop-shaped connecting portion 330. As shown in FIG. 14, the loop-shaped connecting portion 330 is not directly bonded to the insole body 210, but is configured to connect both ends of the insole body 210 and the marker 220 by passing through gaps between the components that make up the insole body 210 (for example, spaces between beams in a lattice structure). That is, the loop-shaped connecting portion 330 is formed from a predetermined location on the marker 220, passes through gaps between the components that make up the insole body 210, and returns to the marker 220 to form a loop. When the marker 220 is removed from the insole body 210, the loop of the loop-shaped connecting portion 330 is cut, so no trace of the cut remains on the insole body 210. That is, the original appearance and functionality of the insole body 210 can be maintained.

[0111] Furthermore, in this embodiment, the marker 220 has a solid surface and is formed so as to include identification information on the solid surface, but this is not limited to this.

[0112] Fig. 15 is a diagram showing an example in which the sign 320 is formed from the shape of the identification information itself. As shown in Fig. 15, the sign 320 does not have a solid surface and is formed from the shapes of the letters, numbers, and symbols that make up the identification information itself. In this case, adjacent letters, numbers, and symbols may be linked to form one sign 320 (identification information).

[0113] In the present embodiment, footwear such as shoes and insoles placed inside the footwear have been described as examples of body-worn articles according to the present disclosure, but the present disclosure is not limited thereto. The present disclosure can be applied to body-worn articles including, for example, clothing (clothing, socks, hats, etc.), accessories, and other products that are used by directly or indirectly fitting to a part of the body (rings, glasses, goggles, earrings, headphones, earphones, etc.).

[0114] Furthermore, in this embodiment, the footwear and insole are manufactured using a three-dimensional lamination method, but this is not limited to this, and other manufacturing methods may also be used.

[0115] [Summary of the effects of this disclosure] According to the present disclosure, in a body-worn item that is used by fitting it to a part of the body, the information display unit is simultaneously molded together with the body-worn item main body, has a connecting unit that connects to the body-worn item main body, and further includes identification information that identifies the body-worn item main body, so that the body-worn item can be properly managed using the identification information while maintaining the original appearance and functionality of the body-worn item.

[0116] FIG. 16 is a diagram showing an overview of the product management system 300. The product management system 300 can integrate and manage information on manufacturing, sales, use, repairs, etc. This allows manufacturers to ensure process transparency and develop and create new businesses using various data. In addition, users can enjoy more personalized product purchasing, after-sales service, and other services.

[0117] Furthermore, since the product management system 300 according to an embodiment of the present disclosure can manage product manufacturers, etc., it is possible to take measures against counterfeit products, for example, by identifying counterfeit products, etc. For example, the administrator of the product management system 300 can identify as counterfeit products products that do not have the identification information attached to genuine products, products that have identification information different from that of genuine products, or products that cannot be associated with product management information that manages genuine products.

[0118] [Aspect] (1) A body-worn item according to one aspect of the present disclosure is a body-worn item that is used by fitting it to a part of the body, and includes a body-worn item main body and an information display unit that is simultaneously formed with the body-worn item main body and has a connecting portion that connects to the body-worn item main body, and the information display unit includes identification information that identifies the body-worn item main body. According to the body-worn item (1) above, the information display unit is simultaneously molded with the body-worn item main body, has a connecting portion that connects to the body-worn item main body, and further includes identification information that identifies the body-worn item main body.Therefore, the body-worn item can be properly managed using the identification information while maintaining its original appearance and functionality.

[0119] (2) In the body wearable product described in (1) above, the information display unit may be configured to be detachable from the body wearable product main body. According to the body-worn product of (2) above, when the body-worn product main body is used, the information display unit does not impair the original appearance and functionality of the body-worn product, and as a result, the original appearance and functionality of the body-worn product can be appropriately maintained.

[0120] (3) In the body-worn product described in (1) or (2) above, the body-worn product main body may have a storage section formed therein capable of storing the information display unit, and the storage section may have a recess formed in the surface of the body-worn product main body to correspond to the shape of the information display unit, and the information display unit may be configured to fit into the recess. According to the body-worn product of (3) above, the information display unit can be stored in a storage compartment in the body-worn product main body, so the information display unit can be managed without being lost while maintaining the original appearance and functionality of the body-worn product. Furthermore, the information display unit is configured to fit into a recess formed in the storage compartment in the body-worn product main body, so the information display unit can be managed without being lost while more appropriately maintaining the original appearance and functionality of the body-worn product.

[0121] (4) In the body-worn product described in any one of (1) to (3) above, at least a part of the body-worn product is footwear or an insole manufactured by additive manufacturing, and the information display unit has a right-foot information display unit corresponding to the right-foot main body of the footwear main body or the insole main body of the insole, and a left-foot information display unit corresponding to the left-foot main body, and the right-foot information display unit and the left-foot information display unit may be formed as a pair. According to the body wearable item (4) above, the information display unit for the right foot and the information display unit for the left foot are formed as a pair, so that they can be properly managed as a single pair of footwear or insole using a single piece of identification information.

[0122] (5) In the body-worn product described in any of (1) to (4) above, the connecting portion may include a state in which the body-worn product main body and the information display unit are physically connected, or a state in which the body-worn product main body and the information display unit are connected in a string-like manner. According to the body-worn item (5) above, the body-worn item main body and the information display unit are connected by a connecting unit, so there is an extremely low possibility of a discrepancy occurring in the correspondence between the identification information contained in the information display unit and the body-worn item main body.

[0123] (6) In the body-worn product described in any one of (1) to (5) above, the information display unit may be connected via a loop-shaped connecting portion that is formed simultaneously with the body-worn product main body so as not to be directly adhered to the body-worn product main body. According to the body-worn product of (6) above, when the information display unit is removed from the body-worn product main body, the loop-shaped connecting part that is not directly bonded to the body-worn product main body is cut, so that no trace of cutting remains on the body-worn product main body, and the original appearance and functionality of the body-worn product can be more appropriately maintained.

[0124] (7) In the body-worn product described in any one of (1) to (6) above, the body-worn product main body may have a corresponding portion corresponding to the connecting portion that is cut from the body-worn product main body, and the cross-sectional shape of the corresponding portion where the connecting portion is cut may be configured to be different from the cross-sectional shape of the corresponding portion in other body-worn products. According to the body-worn item (7) above, after the information display unit is cut off from the body-worn item main body, the combination of the body-worn item main body and the information display unit can be easily determined based on the cross-sectional shape of the corresponding part on the body-worn item main body that corresponds to the connecting part.

[0125] (8) In the body-worn product described in any one of (1) to (7) above, the connecting portion may have a portion near the body-worn product main body that is formed thinner than the average thickness of the connecting portion. According to the body-worn product of (8) above, the connecting portion has a portion near the body-worn product main body that is thinner than the average thickness of the connecting portion, making it easy to cut off the information display unit when removing it from the body-worn product main body, and furthermore, it is possible to reduce or eliminate traces of cutting left on the body-worn product main body, thereby ensuring the original appearance and functionality of the body-worn product.
