Description

Technical Field

[0001] The present invention relates to the technical field of fashion products such as clothing and leather goods, and more particularly to a method for manufacturing such fashion products. Background Art

[0002] Fashion products such as clothing and bags are well known. Generally speaking, the creation process of clothing or bags is as follows. The designer or stylist first designs a pattern for clothing or bags, which is the design stage. Then, samples of clothing or bags are obtained by cutting and assembling, such as sewing, according to the pattern of different fabrics, leather or other materials, which is the sampling stage. If necessary, the pattern is modified to obtain the final pattern, which is the improvement stage. In the improvement stage, multiple sampling steps can be carried out to confirm multiple modification plans. Finally, when the style is accepted, the clothing or bag will be manufactured in an industrialized way by cutting and assembling according to the final pattern of different fabrics, leather or other materials, which is the manufacturing stage. If the style is not accepted, the pattern will be discarded or destroyed.

[0003] However, the creative process, which includes several stages, is usually time-consuming and costly. In particular, the sample-making stage requires very expensive skilled labor. As a result, only a limited number of different styles can be offered each season, due to the time required for the creative process. Furthermore, in order to generate more returns on the costs associated with the creative process, garments or bags are usually produced in large quantities. This means that garments or bags are designed to be worn by as many people as possible, and are not designed to fit every body shape.

[0004] The present invention therefore aims to provide a method allowing the manufacture of garments or bags that better adapt to the consumer's body shape while reducing the use of raw materials required for the creation process, reducing the time and costs, especially labor costs, and in particular reducing the time and costs related to the design, sample making and improvement phases. Summary of the invention

[0005] The solution proposed by the present invention is a method for manufacturing clothing or bags, which comprises the following steps:

[0006] a) record a reference digital pattern for the manufacture of a garment or bag, the reference digital pattern comprising a set of fixed digital points,

[0007] b) generating a manufacturing digital pattern of a garment or bag, the manufacturing digital pattern comprising the set of fixed digital points of the reference digital pattern and at least one digital line connecting at least two fixed digital points,

[0008] c) Record the manufacturing digital drawings in the database,

[0009] d) repeating steps b) and c) a given number of times,

[0010] e) establish at least one selection criterion,

[0011] f) selecting at least two manufacturing digital drawings corresponding to the at least one selection criterion in the database,

[0012] g) determining a final manufacturing digital drawing from the selected manufacturing digital drawings,

[0013] h) Manufacturing of garments or bags according to final manufacturing digital patterns.

[0014] In this way, a large number of digital patterns can be created quickly according to the standards that suit the customer. Therefore, it is not necessary to produce a large number of physical patterns in order to produce a garment or bag. As a result, the use of raw materials is greatly reduced. So is the time and cost required for the creation process. During the manufacturing stage of the garment or bag, any waste of raw materials is avoided by using knitted fabrics, or / or nonwoven fabrics, and / or knitted materials, and / or nonwoven materials, and / or knitted textile fibers, and / or nonwoven textile fibers, and / or polymer fibers.

[0022] g2) Retrieving a selection of a final digital pattern input via a user interface.

[0023] According to another advantageous feature of the invention which allows ensuring that the garment or bag fits the shape of the user, step g) comprises the following steps:

[0024] g1) For each selected manufacturing digital drawing, the following is displayed:

[0025] g11) a three-dimensional rendering of a garment or bag that can be manufactured from the pattern,

[0026] g12) a 3D rendering of the human body dimensions within a 3D rendering of a garment or bag,

[0027] g2) Retrieving a selection of a final digital pattern input via a user interface.

[0028] According to another advantageous feature of the invention allowing the creation of a usable history of the selections made by one or more users, the method comprises the following steps:

[0029] j) Recording data relating the at least one selection criterion established to the final manufacturing digital drawing.

[0030] According to another advantageous feature of the invention, which allows the selection of the digital pattern to be gradually improved by a machine learning method, step f) comprises the following steps:

[0048] The present invention relates to a method for manufacturing a garment or a bag. The garment or bag may be a dress, trousers, a coat, a jacket, a glove, a handbag or any other garment or bag suitable for use by a person skilled in the art. The garment or bag is obtained by assembling at least two parts to each other. The parts may be made of fabric, leather, synthetic material or any other material suitable for use by a person skilled in the art. Different parts may be made of the same material or different materials. The assembly may be achieved by sewing, knitting, buttons, hook and loop fasteners, felting, textile fiber spraying or any other assembly method suitable for use by a person skilled in the art.

[0049] The manufacturing method that is the subject of the invention comprises the following steps.

[0050] a) Recording a reference digital pattern (1) for manufacturing a garment or bag, the reference digital pattern comprising a set of digital dots.

[0051] The so-called "digital" refers to the computer data form representation of an object. For example, a digital pattern is a computer data form representation of a pattern.

[0052] A digital pattern is in the form of a set of digital points. The digital points are arranged in a two-dimensional or three-dimensional digital space. These digital points form one or more straight or curved digital lines, which are combined to generate the digital shape of a garment or bag. A pattern can be composed of a set of sub-patterns. Each sub-pattern exists in the form of a set of digital points, which form one or more straight or curved digital lines, which are combined to generate the digital shape of a component of a garment or bag. The digital shapes of these components are combined to obtain the digital shape of the garment or bag.

[0053] The reference digital pattern (1) is in the form of at least a portion of a digital pattern as described above. The reference digital pattern (1) comprises a set of fixed digital points. It is the basis for creating a complete digital pattern. In some embodiments, the reference digital pattern (1) may be in the form of a complete digital pattern. Figure 1 In the illustrated embodiment, the reference digital pattern (1) may include nine digital lines (11, 12, 13, 14, 15, 16, 17, 18, 19).

[0054] In practice, the execution of the computer program by the microprocessor allows recording on a computer mass storage medium of the hard disk (DD), solid state drive (SSD) type or any other computer mass storage medium suitable for those skilled in the art.

[0055] Before recording is carried out, a reference digital pattern can be imported based on an existing digital pattern (1). In practice, the execution of a computer program by a microprocessor allows the import of a digital pattern.

[0056] In a variant embodiment, before recording, the reference digital drawing (1) can be generated through a user interface and a computer program executed by a microprocessor. The computer program can be, for example, a computer-aided drawing (DAO) software type, a computer-aided design (CAO) software type, or any other computer program suitable for use by a person skilled in the art. The user interface can be composed of a graphical interface displayed on a screen and an active interface, and the active interface includes a keyboard, a mouse, a touch screen, a stylus, or any other active interface suitable for use by a person skilled in the art, either alone or in combination. In practice, the user draws a digital line of the reference digital drawing (1) through the user interface. The reference digital drawing (1) is then recorded on a computer mass storage medium of the above type.

[0057] In another variant embodiment, before recording, the reference digital pattern (1) can be imported from an existing digital pattern as needed, or generated through a user interface and a computer program executed by a microprocessor.

[0058] In another variant embodiment, before step a), the manufacturing method of the subject of the present invention may include the following steps:

[0059] a01) Get the size of the static human body,

[0060] a02) Generate a reference digital pattern (1) based on the acquired dimensions.

[0061] In step a01), a three-dimensional (3D) body scanner, such as a commercially available scanner, or any other method suitable for a person skilled in the art can be used to obtain the static human body dimensions. In particular, sensors can be installed on a static human body, and the position of the sensors in space can be recorded. In a variant embodiment, the body scanner can be in the form of a volumetric video capture device, such as an Azure Kinect type. In another variant embodiment, the body scanner can be in the form of an image-based volumetric capture device. In another variant embodiment, the body scanner can be in the form of a radar volumetric capture device.

[0062] In step a02), the generation of the reference digital pattern (1) may include the following sub-steps:

[0063] a021) Derivation of volume based on the acquired dimensions,

[0064] a022) creates an envelope that encloses the volume,

[0065] a023) modifying one or more given parts of the envelope as required, such as adding functional gaps in parts corresponding to human joints,

[0066] a024) determining one or more combined areas of the envelope to create a reference digital pattern (1).

[0067] In practice, the execution of the computer program by the microprocessor enables step a02) and its sub-steps to be implemented. In particular, the software can be configured to determine in step a023) the portion of the envelope to be modified, such as the portion of the envelope corresponding to the human joint arrangement. In a variant embodiment, the user can initiate the modification in step a023) through a user interface of the above type. The user interface can also be in the form of a virtual or augmented reality interface and, for example, include a virtual or augmented reality helmet. The modification in step a023) can be initiated by one or more movements of the user's hand, a remote control, a stylus, or any other element or method capable of controlling an action through a virtual or augmented reality interface.

[0068] In step a), the manufacturing method of the subject of the present invention may also comprise the following steps:

[0069] a1) Determine a set of fixed digital dots at fixed positions among the digital dots of the reference digital pattern (1).

[0070] In step a), the manufacturing method of the subject of the present invention may also comprise the following steps:

[0071] a2) Determine variable digital dots with variable positions among the digital dots of the reference digital pattern (1).

[0072] In practice, the execution of the computer program by the microprocessor enables step a1) and / or step a2) to be implemented. In particular, the software can be configured to determine variable digital points of variable positions among the digital points of the reference digital pattern (1), and the remaining points are fixed digital points of fixed positions. Conversely, the software can be configured to determine fixed digital points of fixed positions among the digital points of the reference digital pattern (1), and the remaining points are variable digital points of variable positions. In a variant embodiment, in order to determine fixed digital points or variable digital points, the user can select fixed digital points and / or variable digital points through a user interface of the above type. The user interface can also be in the form of a virtual or augmented reality interface, and for example include a virtual or augmented reality helmet. The selection of fixed digital points and / or variable digital points can be achieved by one or more movements of the user's hand, a remote control, a stylus, or any other element or method that can control actions through a virtual or augmented reality interface.

[0073] exist Figure 1 In the embodiment, the digital points forming the digital segments (11 and 12) are fixed digital points, and all other digital points are variable digital points.

[0074] In a variant embodiment, the manufacturing method of the subject of the present invention may also include the following steps:

[0075] a') generating an additional reference digital pattern (2) for manufacturing a garment or a bag, the additional reference digital pattern comprising a set of digital dots.

[0076] The reference digital pattern (1) may correspond to the minimum generation envelope, and the additional reference digital pattern (2) may correspond to the maximum generation envelope. Alternatively, the reference digital pattern (1) may correspond to the maximum generation envelope, and the additional reference digital pattern (2) may correspond to the minimum generation envelope.

[0077] The additional reference digital pattern (2) is in the form of the reference digital pattern as described above. The number of digital dots included in the additional reference digital pattern (2) may be greater, less, or the same as that of the reference digital pattern (1). The number of digital lines formed by the digital dots of the additional reference digital pattern (2) may be greater, less, or the same as that of the reference digital pattern (1). Figure 3 In the illustrated embodiment, the additional reference number pattern (2) may include nine number lines (21, 22, 23, 24, 25, 26, 27, 28, 29).

[0078] The additional reference digital pattern (2) may not include any portion in common with the reference digital pattern (1). In a variant embodiment, the additional reference digital pattern (2) may include at least one portion in common with the reference digital pattern (1). The at least one common portion may be in the form of digital dots or digital lines. Figure 3 In the example of the embodiment shown, the additional reference numeral pattern (2) may include:

[0079] - a first digit line (21) shared with the first digit line (11) of the reference digit pattern (1),

[0080] - a second digital line (22) shared with the second digital line (12) of the reference digital pattern (1),

[0081] - Three digital dots (51, 52, 53) in common with the reference digital pattern (1).

[0082] Similar to reference digital pattern (1), the execution of a computer program by a microprocessor allows recording on a computer mass storage medium of the type described above.

[0083] Furthermore, similar to the reference digital pattern (1), the additional reference digital pattern (2) can be imported from an existing digital pattern before recording, or generated through a user interface and a computer program executed by a microprocessor.

[0084] In addition, similar to the reference digital pattern (1), before step a), the manufacturing method of the subject of the present invention may include the following steps:

[0085] a'01) Get the size of the moving human body,

[0086] a'02) generating an additional reference number pattern (2) according to the acquired dimensions.

[0087] In this way, a garment or bag can be made that better fits the consumer's body shape without having to create multiple physical patterns.

[0088] In step a'01), the dimensions of a moving human body can be obtained using a three-dimensional (3D) human body scanner, such as a commercially available scanner, or any other device suitable for use by a person skilled in the art. In particular, sensors can be mounted on the moving human body, and the continuous position of the sensors in space can be recorded. In a variant embodiment, the human body scanner can be in the form of a volumetric video capture device, such as an Azure Kinect type. In another variant embodiment, the human body scanner can be in the form of a photo-based volumetric capture device. In another variant embodiment, the human body scanner can be in the form of a radar volumetric capture device. The volume defined by a moving human body is necessarily larger than the volume defined by a stationary human body. In addition, obtaining the dimensions of a moving human body allows the generation of additional reference digital patterns (2) that are particularly suitable for human body dynamics.

[0089] In step a'02), the generation of the additional reference digital pattern (2) may include the following sub-steps:

[0090] a'021) Derived volume from the acquired dimensions,

[0091] a'022) creates an envelope that encloses the volume,

[0092] a'023) modifying one or more given parts of the envelope as required, such as adding functional gaps in parts corresponding to human joints,

[0093] a'024) determining one or more combined areas of the envelope to create an additional reference digital pattern (2).

[0094] In practice, the execution of the computer program by the microprocessor enables step a'02) and its sub-steps to be implemented. In particular, the software can be configured to determine multiple parts of the envelope to be modified in step a'023), such as parts of the envelope corresponding to the human body joint arrangement. In a variant embodiment, the user can initiate the modification in step a'023) through a user interface of the above type. The user interface can also be in the form of a virtual or augmented reality interface, and for example include a virtual or augmented reality helmet. In particular, the interface can include a device for displaying a three-dimensional rendering of a pattern, in which a three-dimensional rendering of a moving human body derived from the dimensions obtained in step a'01) can be displayed. The modification in step a'023) can be initiated by one or more movements of the user's hand, a remote control, a stylus, or any other element or method capable of controlling an action through a virtual or augmented reality interface.

[0095] When the method comprises generating an additional reference digital pattern (2), the manufacturing method of the subject of the invention may comprise the following steps:

[0096] a'1) A set of fixed digital dots with fixed positions are determined in the digital dots of the additional reference digital pattern (2).

[0097] In step a'), the manufacturing method of the subject of the present invention may also comprise the following steps:

[0098] a'2) Determining variable digital dots of variable positions in the digital dots of the additional reference digital pattern (2).

[0099] As with reference digital pattern (1), execution of the computer program by the microprocessor enables steps a'1) and / or a'2) to be performed. The selection of fixed digital points and / or variable digital points is achieved in a manner similar to that described above for reference digital pattern (1) using the same type of interface.

[0100] The manufacturing method of the subject of the present invention further comprises the following steps:

[0101] b) generating a manufacturing digital pattern (3) of a garment or bag, the manufacturing digital pattern comprising a set of fixed digital points of the reference digital pattern (1) and at least one digital line connecting at least two fixed digital points.

[0102] When the reference digital pattern (1) includes variable digital dots, at least one digital line connecting at least two fixed digital dots can be obtained by modifying the positions of at least a portion of the variable digital dots.

[0103] When the method comprises generating an additional reference digital pattern (2), the manufacturing method of the subject matter of the invention may further comprise the following steps:

[0104] b') generating an additively manufactured digital pattern of a garment or bag, the additively manufactured digital pattern comprising a set of fixed digital points of the additional reference digital pattern (2) and at least one digital line connecting at least two fixed digital points.

[0105] When the additional reference digital pattern (2) includes variable digital dots, at least one digital line connecting at least two fixed digital dots can be obtained by modifying the positions of at least a portion of the variable digital dots.

[0106] When the method includes generating an additional reference digital pattern (2), the modified position of at least a portion of the variable digital dots causes the manufacturing digital pattern (3) to extend in a space (4) defined by a minimum generation envelope and a maximum generation envelope. Figure 4 , the reference digital pattern (1) and the additional reference digital pattern (2) define a space (4) in which a manufacturing digital pattern can be generated. The space (4) includes boundaries, namely the reference digital pattern (1) and the additional reference digital pattern (2).

[0107] Likewise, when generating the additively manufactured digital pattern, the modified positions of at least a portion of the variable digital dots cause the additively manufactured digital pattern to extend in the space (4) defined by the minimum generation envelope and the maximum generation envelope.

[0108] In a variant embodiment, the modified positions of at least a portion of the variable digital dots make the manufacturing digital pattern (3) at least partially extend outside the space (4) defined by the minimum generation envelope and the maximum generation envelope. Similarly, the modified positions of at least a portion of the variable digital dots make the additional manufacturing digital pattern at least partially extend outside the space (4) defined by the minimum generation envelope and the maximum generation envelope.

[0109] The manufacturing digital pattern (3) is in the form of a digital pattern as described above. The number of digital dots included in the manufacturing digital pattern (3) may be more or less than that of the reference digital pattern (1), or may include the same number of digital dots as the reference digital pattern (1) by extending the digital line. In particular, when the reference digital pattern (1) only includes a set of fixed digital dots, the manufacturing digital pattern (3) includes more digital dots than the reference digital pattern (1). When the reference digital pattern (1) includes variable digital dots in addition to a set of fixed digital dots, the manufacturing digital pattern (3) may include more, less or the same number of digital dots as the reference digital pattern (1). In fact, when several digital dots are moved to the same position, they may be merged. Similarly, when two initially close digital dots are separated, additional digital dots may be created. In addition, in addition to modifying the position of at least some of the variable digital dots, a digital line connecting at least two fixed digital dots may be generated.

[0110] exist Figure 2 In the embodiment of the present invention, the manufacturing digital pattern (3) includes 9 digital lines (31, 32, 33, 34, 35, 36, 37, 38, 39). Since the points at which the digital lines (11, 12) are formed are fixed points, the digital lines (31, 32) of the manufacturing digital pattern (3) are the same as the digital lines (11, 12) of the reference digital pattern (1).

[0111] When there is space (4), all digital lines of the manufacturing digital pattern (3) can be included in space (4). In other words, all digital lines of the manufacturing digital pattern (3) are included on the reference digital pattern (1) and the additional reference digital pattern (2) or included between the reference digital pattern (1) and the additional reference digital pattern (2). Figure 5 In the illustrated embodiment, the manufacturing digital pattern (3) may include nine digital lines (31, 32, 33, 34, 35, 36, 37, 38, 39).

[0112] The additional manufacturing digital pattern is also in the form of the digital pattern as described above. Similar to the manufacturing digital pattern (3), the additional manufacturing digital pattern may include more or less digital dots than the additional reference digital pattern (2), or include the same number of digital dots as the additional reference digital pattern (2) by extending the digital line.

[0113] When space (4) exists, all digital lines of the additionally manufactured digital pattern may be included in space (4). In other words, all digital lines of the manufactured digital pattern (3) are included on the reference digital pattern (1) and the additional reference digital pattern (2), or between the reference digital pattern (1) and the additional reference digital pattern (2).

[0114] When the reference digital pattern (1) and the additional reference digital pattern (2) include one or more common parts, these common parts may correspond to the fixing points of the reference digital pattern (1) and the additional reference digital pattern (2). In this case, the manufacturing digital pattern (3) also includes one or more common parts of the reference digital pattern (1) and the additional reference digital pattern (2). The fixing points usually correspond to the function-related parts of the garment or bag. In order to achieve the function, it is important to maintain the shape and size of the part. For example, the part of the garment or bag can be a cuff, a collar, etc. The part of the garment or bag can also correspond to a part that can be connected to other garments or bags. This is particularly the case when the garment or bag is modular and can be composed of different garment or bag parts. In particular, the reference digital pattern (1), and optionally the additional reference digital pattern (2), can be configured so that at least some modular garment or bag parts are reversible.

[0115] Afterwards, in the presence of an additively manufactured digital pattern, all steps related to manufacturing the digital pattern (3) can be applied to the additively manufactured digital pattern.

[0116] In practice, the execution of the computer program by the microprocessor allows the generation of the digital manufacturing pattern (3). The digital manufacturing pattern (3) can be randomly generated by adding one or more parameters or by any other method suitable for a person skilled in the art. Preferably, the generation of the digital manufacturing pattern (3) is completely automatic. By "automatically", it is meant that the computer program automatically generates the digital manufacturing pattern (3), that is, without user intervention. Preferably, the computer program includes a supervised or unsupervised learning algorithm that allows the generation of the digital manufacturing pattern (3). The unsupervised learning algorithm can specifically be of the "Generative Adversarial Network" (GAN) type.

[0117] The manufacturing method of the subject of the present invention further comprises the following steps:

[0118] c) Recording the manufacturing digital drawing (3) in a database.

[0119] Once recorded, the digital manufacturing pattern can then be used. In practice, the execution of the computer program by the microprocessor enables the digital manufacturing pattern (3) to be recorded in a database. The database may be provided on one or more computer mass storage media of the same type as described above. The database may be relational or object-oriented, or a combination of both.

[0120] The manufacturing method of the subject of the present invention further comprises the following steps:

[0121] d) Repeating steps b) and c) a given number of times.

[0122] In practice, the execution of the computer program by the microprocessor allows to repeat these steps. Advantageously, the given number of times is greater than or equal to 1000 times; preferably, the given number of times is greater than or equal to 100000 times. In this way, a usable digital pattern library is provided. The greater the given number of times, the greater the number of manufacturing digital patterns available in the database. If, during the random generation, the generated manufacturing digital pattern has already been recorded in the database during a previous generation, the generated manufacturing digital pattern will not be recorded in the database again, and step c) is deemed to have been performed.

[0123] The manufacturing method of the subject of the present invention further comprises the following steps:

[0124] e) Establish at least one selection criterion.

[0125] The selection criteria may be of mathematical type, semantic type or any other type suitable for use by a person skilled in the art.

[0126] The at least one selection criterion may be established in different ways. According to a first embodiment, step e) may comprise the following steps:

[0127] e1) Retrieving at least one criterion input via a user interface.

[0128] The user interface is the same type of user interface as described above. At least one criterion may be entered by entering one or more keywords in a text box, or by selecting one or more pre-recorded criteria through a check box, radio button, drop-down menu, or other graphical interface component suitable for use by a person skilled in the art. The criteria may include human body dimensions. The criteria may also include terms related to the shape of a garment or bag, such as long, short, fitted, wide, etc. The criteria may also include terms related to uses such as sports, fashion, leisure, work, etc.

[0129] According to a second embodiment, step e) may include the following steps:

[0130] e2) Obtain human body dimensions.

[0131] The acquisition of the body dimensions can be achieved by a three-dimensional (3D) body scanner, such as a commercially available scanner, or by any other means suitable for use by a person skilled in the art. The body scanner can in particular be a body scanner of the type described above.

[0132] According to a third embodiment example, step e) may include the following steps:

[0133] e3) Generating at least one selection criterion.

[0134] In practice, execution of the computer program by the microprocessor allows generating at least one selection criterion. In particular, the computer program may comprise a supervised or unsupervised learning algorithm configured to generate at least one selection criterion.

[0135] In some example embodiments, step e) may include generating at least one selection criterion according to step e3), and / or obtaining human body dimensions according to step e2), and / or retrieving at least one criterion input through a user interface according to step e1).

[0136] The manufacturing method of the subject of the present invention further comprises the following steps:

[0137] f) selecting at least two manufacturing digital drawings corresponding to at least one selection criterion in the database.

[0138] In practice, the execution of the computer program by the microprocessor allows the selection of the manufacturing digital pattern.According to an embodiment example, one or more criteria may be associated with one or more digital patterns in the database.

[0139] When at least one standard is associated with the manufacturing digital drawing, the program determines whether the selected standard is the same as or similar to one of the associated standard types. For example, if the selected standard is "large" and the associated standard type is "long", the program determines that the two standards are similar. If the selected standard is the same as or similar to one of the associated standard types, the manufacturing digital drawing is selected.

[0140] If the selection criterion is not the same or similar to any of the associated standard types, the program determines whether the selection criterion is opposite to one of the associated standard types. For example, if the selection criterion is "large" and the associated standard type is "short", the program determines that the two criteria are opposite. If the selection criterion is opposite to one of the associated standard types, the manufacturing digital drawing is not selected.

[0141] If the selection criteria are neither identical nor similar nor opposite to the associated standard type, the program may select the manufacturing digital pattern. This selection may be done systematically or randomly.

[0142] When any standard type is not associated with a manufacturing digital drawing, the program can select the manufacturing digital drawing.

[0143] In a variant embodiment, in addition to step f), the method may further include the following steps:

[0144] f') selecting in the database at least one additively manufactured digital pattern corresponding to at least one selection criterion.

[0145] The manufacturing method of the subject of the present invention further comprises the following steps:

[0146] g) determining a final manufacturing digital drawing from among the selected manufacturing digital drawings and optionally among the selected additional manufacturing digital drawings.

[0147] According to an embodiment example, the selected manufacturing digital drawings are provided to the user, from which the user selects the final manufacturing digital drawings via a user interface. The user interface is the same as the user interface of the type described above.

[0148] To this end, step g) may include the following steps:

[0149] g1) for each selected digital manufacturing pattern, displaying a three-dimensional rendering of a garment or bag that can be manufactured according to the pattern,

[0150] g2) Retrieving a selection of a final digital pattern input via a user interface.

[0151] In practice, execution of the computer program by the microprocessor allows the display of a three-dimensional rendering of a garment or bag. The computer program is a conventional software three-dimensional rendering engine type well known to those skilled in the art. The selection of the final digital pattern can be input by clicking a mouse on the rendering, a button on a graphical interface, or by any other selection means suitable for use by those skilled in the art.

[0152] In a variant embodiment, step g) may include the following steps:

[0153] g1) For each selected manufacturing digital drawing, display:

[0154] g11) a three-dimensional rendering of a garment or bag that can be manufactured from the pattern,

[0155] g12) a 3D rendering of the human body dimensions within a 3D rendering of a garment or bag,

[0156] g2) Retrieving a selection of a final digital pattern input via a user interface.

[0157] Similar to clothing or bags, the execution of a computer program by a microprocessor allows a three-dimensional rendering of the human body dimensions to be displayed. The overlay of the rendering allows visual assurance that the digital pattern provided for manufacturing fits the human form.

[0158] Advantageously, the method may comprise the following steps:

[0159] j) Recording data relating the at least one selection criterion established to the final manufacturing digital drawing.

[0160] Thus, if the same or similar selection criteria are subsequently established, it is possible to find a final production digital drawing that clearly meets the criteria and is therefore also an appropriate proposal for the user. In practice, the execution of the computer program by the microprocessor allows the association data to be recorded in a database, which is arranged on a computer mass storage medium of the above-mentioned type. The association data may include a plurality of data, in particular data "criteria" including one or more established selection criteria, and data "drawing" corresponding to the link to the final production digital drawing.

[0161] In order to utilize the recorded association data, step f) may include the following steps:

[0162] f1) comparing at least one selection criterion with each previously recorded relevance data,

[0163] f2) selecting at least two manufacturing digital drawings from the database, for which at least one selection criterion corresponds to previously recorded association data.

[0164] In particular, at least one selection criterion corresponds to previously recorded association data when the at least one selection criterion is similar or identical to the data "criterion" of the association data. As an alternative or in addition to the steps described above for step f), step f) may include steps f1) and f2).

[0165] Therefore, with the use of the manufacturing method of the subject of the present invention, more and more standards are associated with the manufacturing digital drawings, thereby greatly improving the efficiency of searching the manufacturing digital drawings by standards.

[0166] The manufacturing method of the subject of the invention finally comprises the following steps:

[0167] h) Manufacturing of garments or bags according to final manufacturing digital patterns.

[0168] For this purpose, the final manufacturing digital pattern can be sent to the digital manufacturing unit.Then, the digital manufacturing unit can partially or completely perform the steps required for manufacturing clothing or bags, in particular one or more material cutting, and then assembling, such as assembling by sewing, etc.Preferably, the digital manufacturing unit can completely perform the steps required for manufacturing clothing or bags.Thus, the steps and related calculations of pattern setting and scale setting can be avoided, and the pattern setting and scale setting steps and calculations are usually performed when using two-dimensional images.The manufacturing unit may include a three-dimensional printer, and / or a textile spraying machine, and / or a CNC loom, and / or a CNC non-woven fabric machine, and / or a CNC weaving machine, and / or a CNC felt press, and / or a CNC fabric cutting machine, and / or a CNC sewing machine, and / or any other device suitable for the technicians in the field for manufacturing clothing or bags.Preferably, the manufacturing unit includes a three-dimensional printer, and / or a textile spraying machine, and / or a CNC loom, and / or a CNC weaving machine, and / or a CNC felt press to avoid any cutting and to produce clothes in the case of avoiding waste of raw materials. As an alternative or in addition to manufacturing by a digital manufacturing unit, the final manufacturing digital pattern can be printed or displayed on a screen. The production line is then set up according to the final manufacturing digital pattern. The production line may include a loom, and / or a nonwoven machine, and / or a felt press, and / or a fabric cutting machine, and / or a sewing machine, or any other device suitable for use by a person skilled in the art for manufacturing clothing or bags. The clothing or bags are then manufactured on the production line set up in this way.

[0169] The manufacturing method that is the subject of the invention may also comprise, between step g) and step h), a step of modifying the final digital pattern:

[0170] i) Modify the final manufacturing digital drawing.

[0171] In practice, the execution of the computer program by the microprocessor allows the final digital pattern to be modified through a user interface of the type described above. Furthermore, as in steps a0) and a'0), the user interface may be in the form of a virtual or augmented reality interface and may include, for example, a virtual or augmented reality helmet. The modification in step i) may be initiated by one or more movements of the user's hand, a remote control, a stylus or any other element or means that allows the control of actions through a virtual or augmented reality interface. For example, the user may create a cutting line on the final digital pattern with one movement.

[0172] In a variant embodiment, step i) may include the following sub-steps:

[0173] i1) Get the new size of the moving human body,

[0174] i2) deriving a new volume from the acquired dimensions,

[0175] i3) Superimpose the final manufacturing digital pattern and the new volume,

[0176] i4) modifying the final manufactured digital pattern so that any point of the final manufactured digital pattern encloses the volume.

The manufacturing method is particularly suitable for manufacturing modular garments or bags. The garment or bag is broken down into different parts that can be assembled or not assembled as needed to adapt the garment to a specific style or occasion.
