Description

Title of the invention: Method for manufacturing a garment or bag, associated computer program and installation. Technical field of the invention

[0001] The present invention relates to the technical field of fashion articles such as clothing and leather goods, and more particularly to the manufacturing processes of such fashion articles. State of the art

[0002] We are familiar with fashion items such as clothing, bags, etc. Generally, the creative process for a garment or bag unfolds as follows. A designer, or stylist, begins by creating a pattern for the garment or bag; this is the design stage. Next, a prototype of the garment or bag is made by cutting and then assembling, for example by sewing, different pieces of fabric, leather, or other material according to the pattern; this is the prototyping stage. If necessary, modifications are made to the pattern to obtain a final pattern; this is the development stage. Several prototyping stages may take place during the development stage to validate the various modifications. Finally, once the design is approved, the garment or bag is manufactured industrially by cutting and assembling different pieces of fabric, leather, or other material according to the final pattern; this is the manufacturing stage.When the design is not chosen, the pattern is thrown away or destroyed.

[0003] However, the creative process, which involves numerous steps, is generally lengthy and expensive. In particular, the prototyping stage requires highly skilled labor, which is very costly. Thus, each season, due to the time required for the creative process, it is only possible to offer a limited number of different models. Also, in order to recoup the costs associated with the creative process, the garment or bag is generally mass-produced. Consequently, the garment or bag is designed to be worn by the largest possible number of people without being adapted to individual body shapes.

[0004] Therefore, the invention aims to provide a process for manufacturing a garment or bag better suited to the consumer's morphology while reducing the use of raw materials, as well as the time and costs, in particular labor, required for the creative process, and in particular, the time and costs related to the design, prototyping and development stages. Disclosure of the invention

[0005] The solution proposed by the invention is a method for manufacturing a garment or bag comprising the following steps: a) Record a digital reference pattern for manufacturing a garment or bag comprising a set of fixed digital stitches, b) Generate a digital manufacturing pattern for the garment or bag comprising all the fixed digital points of the reference digital pattern and at least one digital line connecting at least two fixed digital points, c) Save the digital manufacturing pattern in a database, d) Repeat steps b) and c) a specified number of times, e) Establish at least one selection criterion, f) Select from the database at least two digital manufacturing patterns corresponding to at least one selection criterion, g) Determine the final digital manufacturing pattern from among the selected digital manufacturing patterns, h) Manufacture the garment or bag according to the final digital manufacturing pattern.

[0006] Thus, it is possible to quickly create a large number of digital patterns according to criteria adapted to the client. Consequently, it is possible to produce a garment or bag without having to create multiple physical patterns. The use of raw materials is then significantly reduced. The same is true for the time and costs required for the creative process. The use of knitted or non-woven fabrics in the garment or bag manufacturing stage avoids any waste of raw materials.

[0007] According to an advantageous feature of the invention allowing the user to have a large number of possibilities for digital patterns, in step d) the determined number of times is greater than or equal to 1000.

[0009] According to yet another advantageous feature of the invention enabling the manufacture of a fashion item adapted to the body measurements of a consumer, step e) comprises the step: e2) Acquire body measurements.

[0010] According to yet another advantageous feature of the invention which makes it possible to eliminate the prototyping step of the garment or bag, step g) comprises the following steps: gl) Display, for each selected digital manufacturing pattern, a three-dimensional rendering of the garment or bag that can be manufactured according to said pattern, g2) Retrieve a choice of the final digital pattern entered via a user interface.

[0011] According to yet another advantageous feature of the invention which makes it possible to ensure that the garment or bag is adapted to the morphology of a user, step g) comprises the steps: gl) Display, for each selected digital manufacturing pattern: gl 1) A three-dimensional rendering of the garment or bag that can be manufactured according to said pattern, gl2) A three-dimensional rendering of the body measurements within the three-dimensional rendering of the garment or bag, g2) Retrieve a choice of the final digital pattern entered via a user interface.

[0013] According to yet another advantageous feature of the invention which allows for the progressive improvement of the selection of digital patterns by a machine learning method, step f) comprises the following steps: fl) Compare at least one selection criterion with each previously recorded correlation data, f2) Select from the database at least two digital manufacturing patterns for which at least one selection criterion corresponds to the previously recorded correlation data.

[0014] Another aspect of the invention relates to a garment or bag remarkable in that it is manufactured according to the process which is the subject of the invention.

[0015] The garment or bag is thus better suited to the customer's criteria and obtained in a reduced time.

[0016] Yet another aspect of the invention relates to a computer program characterized in that it is intended to be executed by a microprocessor in such a way as to implement the steps of the manufacturing process of a garment or bag which is the subject of the invention.

[0025] The invention relates to a method for manufacturing a garment or 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 to a person skilled in the art. The garment or bag is obtained by joining at least two pieces together. A piece may be made of fabric, leather, synthetic material, or any other material suitable to a person skilled in the art. The different pieces may be made of the same material or of different materials. The joining may be done by sewing, stitching, buttoning, hook and loop fasteners, or any other means of joining suitable to a person skilled in the art.

[0026] The manufacturing process that is the subject of the invention comprises the step: a) Record a digital reference pattern (1) for the manufacture of a garment or bag comprising a set of digital stitches.

[0027] The term "digital" means the representation of an object in the form of computer data. For example, a digital pattern is the representation of a pattern in the form of computer data.

[0028] A digital pattern is represented as a set of digital points. These digital points are arranged in a two- or three-dimensional digital space. These digital points form one or more digital lines, straight or curved, which are assembled to generate the digital shape of the garment or bag. The pattern may be composed of a set of sub-patterns. Each sub-pattern is represented as a set of digital points, which form one or more digital lines, straight or curved, assembled to generate the digital shape of parts of the garment or bag. Assembling the digital shapes of these parts yields the digital shape of the garment or bag.

[0029] The reference digital pattern (1) is in the form of at least a part of a digital pattern as previously described. The reference digital pattern (1) comprises a set of fixed digital points. It serves as 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. As in the embodiment shown in Figure [Fig. 1], the reference digital pattern (1) may comprise 9 digital lines (11, 12, 13, 14, 15, 16, 17, 18, 19).

[0030] In practice, the execution of a computer program by a microprocessor allows recording on a computer mass storage medium such as a hard disk drive (HDD), solid-state drive (SSD), or any other computer mass storage medium suitable to a person skilled in the art.

[0031] Prior to registration, the reference digital pattern (1) can be imported from a pre-existing digital pattern. In practice, the execution of a computer program by a microprocessor allows the import of the digital pattern.

[0032] In one embodiment, prior to registration, the digital reference pattern (1) can be generated by means of a user interface and a computer program executed by a microprocessor. The computer program can, for example, be computer-aided design (CAD) software, computer-aided manufacturing (CAM) software, or any other computer program suitable for those skilled in the art. The user interface can consist of a graphical interface displayed by a screen and an active interface comprising, individually or in combination, a keyboard, a mouse, a touchscreen, a stylus, or any other active interface suitable for those skilled in the art. In practice, the user draws the digital lines of the digital reference pattern (1) at user interface means. The digital reference pattern (1) is then recorded on a computer mass storage medium of the type previously described.

[0033] In another embodiment, prior to registration, the reference digital pattern (1) can be, at will, imported from a pre-existing digital pattern or generated by means of a user interface and a computer program executed by a microprocessor.

[0034] In yet another embodiment, prior to step a), the manufacturing process which is the subject of the invention may include the steps: a01) Acquire measurements of an immobile body, a02) Generate a digital reference pattern (1) from the measurements acquired.

[0035] In step a01), measurements of the stationary body can be carried out using a three-dimensional (3D) body scanner such as those available on the market or by any other means suitable to a person skilled in the art. In particular, sensors can be positioned on a stationary body and the position of the sensors in space can be recorded.

[0036] In step a02), the generation of the reference digital pattern (1) may include the following sub-steps: a021) Extrapolate a volume from the acquired measurements, a022) Create an envelope surrounding the volume, a023) Modify possibly one or more determined parts of the envelope, for example to add functional clearances at the level of the parts opposite the joints of the body, a024) Determine one or more assembly areas of the envelope so as to create the digital reference pattern (1).

[0037] In practice, the execution of a computer program by a microprocessor enables the implementation of step a02) and its substeps. The software can, in particular, be configured to determine, in step a023), the parts of the envelope to be modified, for example, the parts of the envelope arranged opposite the body's joints. In alternative embodiments, the user can initiate modifications in step a023) via a user interface of the type described above. The user interface can also take the form of a virtual or augmented reality interface, and, for example, include a virtual or augmented reality headset.The modifications 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 allowing actions to be controlled through the virtual or augmented reality interface.

[0038] In step a), the manufacturing process that is the subject of the invention may also include the step: al) Determine among the numerical points of the reference numerical pattern (1) a set of fixed numerical points of fixed position.

[0039] In step a), the manufacturing process that is the subject of the invention may also include the step: a2) Determine among the numerical points of the reference numerical pattern (1) variable numerical points of variable position.

[0040] In practice, the execution of a computer program by a microprocessor allows the implementation of step a1) and / or a2). The software can, in particular, be configured to determine, among the digital points of the reference digital pattern (1), the variable digital points of variable position, the remaining points being fixed digital points of fixed position. Conversely, the software can be configured to determine, among the digital points of the reference digital pattern (1), the fixed digital point(s) of fixed position, the remaining points being variable digital points of variable position. In alternative embodiments, to determine the fixed or variable digital points, the user can select the fixed digital points, and / or the variable digital points, via a user interface of the type described above.The user interface can also take the form of a virtual or augmented reality interface, and for example include a virtual or augmented reality headset. The selection of fixed digital points, and / or variable digital points, can be performed by one or more movements of the user's hand, a remote control, a stylus, or any other element or method allowing actions to be controlled through the virtual or augmented reality interface.

[0041] In the embodiment example of figure [Fig.1], the numerical points forming the numerical segments (11 and 12) are fixed numerical points, the set of all other numerical points being variable numerical points.

[0042] In one embodiment, the manufacturing process that is the subject of the invention may also include the following step: a') Generate an additional digital reference pattern (2) for the manufacture of the garment or bag comprising a set of digital points.

[0043] The reference digital pattern (1) can then correspond to a minimum generation envelope and the additional reference digital pattern (2) to a maximum generation envelope. Alternatively, the reference digital pattern (1) can correspond to a maximum generation envelope and the additional reference digital pattern (2) correspond to a minimum generation envelope.

[0044] The additional reference digital pattern (2) is in the form of a reference digital pattern as previously described. It may comprise more, fewer, or the same number of digital points as the reference digital pattern (1). The digital points of the additional reference digital pattern (2) may form more, fewer, or the same number of digital lines as the reference digital pattern (1). As in the embodiment shown in Figure [Fig. 3], the additional reference digital pattern (2) may comprise 9 digital lines (21, 22, 23, 24, 25, 26, 27, 28, 29).

[0045] The additional digital reference pattern (2) may not include any part in common with the digital reference pattern (1). In alternative embodiments, the additional digital reference pattern (2) may include at least one part in common with the digital reference pattern (1). This at least one part in common may be in the form of a digital point or a digital line. As in the embodiment shown in Figure [Fig. 3], the additional digital reference pattern (2) may include: - A first digital line (21) in common with a first digital line (11) of the reference digital pattern (1), - A second numerical line (22) in common with a second numerical line (12) of the reference numerical pattern (1), - Three numerical points (51, 52, 53) in common with the reference numerical pattern (1).

[0046] Similar to the reference digital pattern (1), the execution of a computer program by a microprocessor allows recording on a computer mass storage medium of the type previously described.

[0047] Also, and similarly to the reference digital pattern (1), the additional reference digital pattern (2) can, prior to registration, be imported from a pre-existing digital pattern or generated by means of a user interface and a computer program executed by a microprocessor.

[0048] Again, and similarly to the reference digital pattern (1), prior to step a'), the manufacturing process of the invention may include the steps: a'01) Acquire measurements of the moving body, a'02) Generate an additional reference digital pattern (2) from the acquired measurements.

[0049] Therefore, it is possible to produce a garment or bag better suited to the consumer's morphology without having to manufacture a plurality of physical patterns.

[0050] In step a'01), measurements of the moving body can be taken using a three-dimensional (3D) body scanner such as those available on the market or by any other means suitable to a person skilled in the art. In particular, sensors can be positioned on a moving body, and the successive positions of the sensors in space can be recorded. The volume delimited by the moving body is thus necessarily larger than the volume delimited by the stationary body. Furthermore, acquiring measurements on a moving body makes it possible to generate an additional digital reference pattern (2) particularly suited to the body's dynamics.

[0051] In step a'02), the generation of the additional digital reference pattern (2) may include the following substeps: a'021) Extrapolate a volume from the acquired measurements, a'022) Create an envelope surrounding the volume, a'023) Modify possibly one or more determined parts of the envelope, for example to add functional clearances at the level of the parts opposite the joints of the body, a'024) Determine one or more assembly areas of the envelope so as to create the additional digital reference pattern (2).

[0052] In practice, the execution of a computer program by a microprocessor enables the implementation of step a'02) and its substeps. The software can, in particular, be configured to determine in step a'023) which parts of the envelope are to be modified, for example, the parts of the envelope arranged opposite the body's joints. In alternative embodiments, the user can initiate modifications in step a'023) via a user interface of the type described above. The user interface can also take the form of a virtual or augmented reality interface, and for example, include a virtual or augmented reality headset. In particular, the interface can include a means for displaying a three-dimensional rendering of the pattern, within which a three-dimensional rendering of the moving body, extrapolated from the measurements acquired in step a'01), can be displayed.The modifications 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 allowing actions to be controlled through the virtual or augmented reality interface.

[0053] When the process includes the generation of an additional digital reference pattern (2), the manufacturing process of the invention may then include the step: a' 1) Determine among the numerical points of the additional reference numerical pattern (2) a set of fixed numerical points of fixed position.

[0054] In step a'), the manufacturing process that is the subject of the invention may also include the step: a'2) Determine among the numerical points of the additional reference numerical pattern (2) variable numerical points of variable position.

[0055] As with the reference digital pattern (1), the execution of a computer program by a microprocessor allows the implementation of step a'1) and / or a'2). The selection of fixed digital points and / or variable digital points is carried out in a similar way to the way described above for the reference digital pattern (1) using the same type of interface.

[0056] The manufacturing process of the invention also includes the step: b) Generating a digital manufacturing pattern (3) of the garment or bag comprising the set of fixed digital points of the reference digital pattern (1) and at least one digital line connecting at least two fixed digital points.

[0057] When the reference digital pattern (1) has variable digital points, at least one digital line connecting at least two fixed digital points can be obtained by changing the position of at least some of said variable digital points.

[0058] When the process includes the generation of an additional digital reference pattern (2), the manufacturing process of the invention may further include the step: b') Generate an additional digital manufacturing pattern for the garment or bag comprising the 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.

[0059] When the additional digital reference pattern (2) has variable digital points, at least one digital line connecting at least two fixed digital points can be obtained by changing the position of at least some of the variable digital points.

[0060] When the method includes the generation of an additional digital reference pattern (2), the modified position of at least some of the variable digital points is such that the manufacturing digital pattern (3) extends within a space (4) delimited by the minimum generation envelope and the maximum generation envelope. With reference to Figure [Fig. 4], the digital reference pattern (1) and the additional digital reference pattern (2) delimit a space (4) within which it is possible to generate manufacturing digital patterns. The space (4) includes its boundaries, that is, the digital reference pattern (1) and the additional digital reference pattern (2).

[0061] Similarly, when an additional digital manufacturing pattern is generated, the modified position of at least part of the variable digital points is such that said additional digital manufacturing pattern extends into a space (4) delimited by the minimum generation envelope and the maximum generation envelope.

[0062] In alternative embodiments, the modified position of at least some of the variable digital points is such that the manufacturing digital pattern (3) extends at least partially outside the space (4) delimited by the minimum generation envelope and the maximum generation envelope. Similarly, the modified position of at least some of the variable digital points may be such that the additional manufacturing digital pattern extends at least partially outside the space (4) delimited by the minimum generation envelope and the maximum generation envelope.

[0063] The digital manufacturing pattern (3) is in the form of a digital pattern as previously described. It may include more, fewer, or the same number of digital points, and by extension, digital lines, as the reference digital pattern (1). In particular, when the reference digital pattern (1) comprises only a set of fixed digital points, the digital manufacturing pattern (3) has more digital points than the reference digital pattern (1). When the reference digital pattern (1) includes, in addition to the set of fixed digital points, variable digital points, the digital manufacturing pattern (3) may include more, fewer, or the same number of digital points as the reference digital pattern (1). Indeed, when several digital points are moved to the same location, they can be merged.Similarly, when two initially close digital points are separated, additional digital points can be created. Furthermore, digital lines connecting at least two fixed digital points can be generated, in addition to modifying the position of at least some of the variable digital points.

[0064] In the embodiment shown in Figure [Fig. 2], the digital manufacturing pattern (3) comprises 9 digital lines (31, 32, 33, 34, 35, 36, 37, 38, 39). The digital lines (31 and 32) of the digital manufacturing pattern (3) are identical to the digital lines (11 and 12) of the reference digital pattern (1) since the points forming the digital lines (11 and 12) are fixed points.

[0065] When space (4) exists, all the digital lines of the manufacturing digital pattern (3) can be contained within space (4). In other words, all the digital lines of the manufacturing digital pattern (3) are contained on, or between, the reference digital pattern (1) and the additional reference digital pattern (2). As in the embodiment shown in Figure [Fig. 5], the pattern digital manufacturing (3) can include 9 digital lines (31, 32, 33, 34, 35, 36, 37, 38, 39).

[0066] The additional digital manufacturing pattern is in the form of a digital pattern as previously described. Similar to the digital manufacturing pattern (3), the additional digital manufacturing pattern may include more, fewer, or the same number of digital points, and by extension digital lines, as the additional reference digital pattern (2).

[0067] When space (4) exists, all the digital lines of the additional digital manufacturing pattern can be contained within space (4). In other words, all the digital lines of the digital manufacturing pattern (3) are contained on, or between, the reference digital pattern (1) and the additional reference digital pattern (2).

[0068] When the reference digital pattern (1) and the additional reference digital pattern (2) have one or more parts in common, these common parts may correspond to fixed points of the reference digital pattern (1) and the additional reference digital pattern (2). In such a case, the manufacturing digital pattern (3) also has said part(s) in common with the reference digital pattern (1) and the additional reference digital pattern (2). The fixed points generally correspond to a part of the garment or bag to which a function is associated. For this function to exist, it is important to maintain the shape and dimensions of this part. The part of the garment or bag may, for example, be an armhole, a neckline, or something similar. The part of the garment or bag may also correspond to a part capable of interconnecting with other garments or bags.This is particularly relevant when a garment or bag is modular and can be composed of an assembly of different garment or bag sub-items. In particular, the reference digital pattern (1), and possibly the additional reference digital pattern (2), can be configured so that at least some of the modular garment or bag sub-items are reversible.

[0069] Subsequently, all the steps concerning the digital manufacturing pattern (3) can be applied to the additional digital manufacturing pattern when the latter exists.

[0070] In practice, the execution of a computer program by a microprocessor enables the generation of the digital manufacturing pattern (3). This pattern can be generated randomly, by incrementing one or more parameters, or by any other means suitable to a person skilled in the art. Preferably, the generation of the digital manufacturing pattern (3) is entirely automatic. By "automatic," it is meant that the computer program generates the pattern digital manufacturing (3) autonomously, 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, in particular, be of the "generative adversarial networks" (GANs) type.

[0071] The manufacturing process that is the subject of the invention further comprises the step: c) Save the digital manufacturing pattern (3) in a database.

[0072] Thus, once recorded, this digital manufacturing pattern can be used subsequently. In practice, the execution of a computer program by a microprocessor allows the digital manufacturing pattern (3) to be recorded in the database. The database can be stored on one or more computer mass storage media of the same type as previously described. The database can be relational or object-oriented, or a combination of both.

[0073] The manufacturing process which is the subject of the invention further includes the step: d) Repeating steps b) and c) a determined number of times.

[0074] In practice, the execution of a computer program by a microprocessor allows these steps to be repeated. The predetermined number of times is advantageously greater than or equal to 1,000, preferably greater than or equal to 100,000. This provides a library of usable digital patterns. The greater the predetermined number of times, the greater the number of digital manufacturing patterns available in the database. If, during a random generation, the generated digital manufacturing pattern had already been recorded in the database during a previous generation, then said generated digital manufacturing pattern is not re-recorded in the database and step c) is deemed to have been executed.

[0075] The manufacturing process which is the subject of the invention further includes the step: e) Establish at least one selection criterion.

[0076] The selection criterion may be mathematical, semantic or of any other type suitable to a person skilled in the art.

[0077] At least one selection criterion can be established in different ways. According to a first embodiment, step e) can include step el) Retrieving at least one criterion entered via a user interface.

[0078] The user interface is of the same type as the user interface described above. At least one criterion can be entered by typing one or more keywords in a text box, by selecting one or more pre-recorded criteria via checkboxes, radio buttons, drop-down menus, or other graphical interface components suitable for a person skilled in the art. These criteria may include body dimensions. They may also include Terms relating to the shape of the garment or bag, such as long, short, fitted, loose, etc. They may also include terms relating to use: sport, chic, casual, work, etc.

[0079] According to a second embodiment, step e) may include step: e2) Acquire body measurements.

[0080] Body measurements can be acquired using a three-dimensional (3D) body scanner such as those available on the market or by any other means suitable to a person skilled in the art.

[0081] According to a third embodiment, step e) may include step: e3) Generate at least one selection criterion.

[0082] In practice, the execution of a computer program by a microprocessor allows the generation of at least one selection criterion. In particular, the computer program may include a supervised or unsupervised learning algorithm configured to generate at least one selection criterion.

[0083] In some embodiment examples, step e) may include the generation of at least one selection criterion according to step e3) and / or the acquisition of body measurements according to step e2), and / or the retrieval of at least one criterion entered via a user interface according to step e1).

[0084] The manufacturing process of the invention further includes the step: f) Selecting, from the database, at least two digital manufacturing patterns corresponding to at least one selection criterion.

[0085] In practice, the execution of a computer program by a microprocessor allows the selection of digital manufacturing patterns. According to an example embodiment, one or more standard criteria can be associated with one or more digital patterns in the database.

[0086] When at least one standard criterion is associated with a digital manufacturing pattern, the program determines whether the selection criterion is identical or similar to one of the associated standard criteria. For example, if the selection criterion is "large" and the associated standard criterion is "long," the program determines that the two criteria are similar. If the selection criterion is identical or similar to one of the associated standard criteria, then the digital manufacturing pattern is selected.

[0087] If the selection criterion is not identical or similar to any of the associated standard criteria, the program determines whether the selection criterion is contrary to one of the associated standard criteria. For example, if the selection criterion is "large" and the associated standard criterion is "short," the program determines that the two criteria are contrary. If the selection criterion is contrary to one of the associated standard criteria, then the digital manufacturing pattern will not be selected.

[0088] If the selection criterion is neither identical nor similar to, nor contrary to, the associated standard criteria, then the program can select the digital manufacturing pattern. This selection can be made systematically or randomly.

[0089] When no type criterion is associated with a digital manufacturing pattern, then the program can select the digital manufacturing pattern.

[0090] In alternative embodiments, the process may include, in addition to step f), the following step: f') Select, from the database, at least one additional digital manufacturing pattern corresponding to at least one selection criterion.

[0091] The manufacturing process that is the subject of the invention further comprises the step: g) Determine the final digital manufacturing pattern from among the selected digital manufacturing patterns and possibly the additional selected digital manufacturing patterns.

[0092] According to one embodiment, the selected digital manufacturing patterns are presented to the user, who selects the final digital manufacturing pattern via a user interface. The user interface is of the same type as that described previously.

[0093] To do this, step g) may include the following steps: gl) Display, for each selected digital manufacturing pattern, a three-dimensional rendering of the garment or bag that can be manufactured according to said pattern, g2) Retrieve a choice of the final digital pattern entered via a user interface.

[0094] In practice, the execution of a computer program by a microprocessor allows the three-dimensional rendering of the garment or bag to be displayed. The computer program is a conventional software three-dimensional rendering engine, well known to those skilled in the art. The selection of the final digital pattern can be made by clicking on the rendering, by clicking a button in the graphical interface, or by any other selection method suitable to those skilled in the art.

[0095] In one embodiment, step g) may include the steps: gl) Display, for each selected digital manufacturing pattern: gl 1) A three-dimensional rendering of the garment or bag that can be manufactured according to said pattern, g 12) A three-dimensional rendering of the body measurements within the three-dimensional rendering of the garment or bag, g2) Retrieve a selection of the final digital pattern entered via a user interface.

[0096] Similar to clothing or bags, the execution of a computer program by a microprocessor allows for the display of a three-dimensional rendering of body measurements. The superimposition of these renderings allows for visual verification that the proposed digital manufacturing pattern is suitable for the individual's body shape.

[0097] Advantageously, the process may include the step: j) Record a correlation data between the at least one established selection criterion and the final digital manufacturing pattern.

[0098] Thus, subsequently, if an identical or similar selection criterion is established, it is possible to retrieve this final digital manufacturing pattern, which clearly corresponds to the criteria and is therefore a relevant option for the user. In practice, the execution of a computer program by a microprocessor allows the correlation data to be recorded in a database stored on a computer mass storage medium of the type described above. The correlation data may include several data points, notably a "criteria" data point comprising the established selection criterion or criteria and a "pattern" data point corresponding to a link to the final digital manufacturing pattern.

[0099] In order to exploit the recorded correlation data, step f) may then include the following steps: fl) Compare at least one selection criterion with each previously recorded correlation data point, f2) Select from the database at least two digital manufacturing patterns for which at least one selection criterion corresponds to the previously recorded correlation data.

[0100] In particular, at least one selection criterion corresponds to the previously recorded correlation data when the selection criterion is similar or identical to the "criteria" data in the correlation data. Step f) may include steps fl) and f2), either alternatively or in addition to the steps previously described for step f).

[0101] Thus, as the manufacturing process of the invention is used, more and more criteria are associated with the digital manufacturing patterns, thereby greatly improving the efficiency of the search by criteria for digital manufacturing patterns.

[0102] The manufacturing process that is the subject of the invention finally comprises the step: h) Manufacture the garment or bag according to the final digital manufacturing pattern.

[0103] To this end, the final digital manufacturing pattern can be sent to a digital manufacturing unit. This unit can then carry out, partially or entirely, the steps necessary for manufacturing the garment or bag, including cutting the materials and then assembling them, for example by means of stitching, etc. The manufacturing unit may include a three-dimensional printer and / or a numerically controlled weaving machine and / or a numerically controlled non-woven fabric machine and / or a numerically controlled felting machine and / or a numerically controlled textile cutting machine and / or a numerically controlled sewing machine and / or any other means of manufacturing a garment or a bag suitable for a person skilled in the art. Alternatively, or in addition to manufacturing via the digital manufacturing unit, the final digital manufacturing pattern can be printed or viewed on a screen. A production line is then configured according to the final digital manufacturing pattern. The production line may include a weaving machine and / or a non-woven fabric machine and / or a felting machine and / or a textile cutting machine and / or a sewing machine, or any other garment or bag manufacturing equipment suitable for a person skilled in the art. The garment or bag is then manufactured on the production line thus configured.

[0104] The manufacturing process that is the subject of the invention may also include, between step g) and step h), a step of retouching the final digital pattern: i) Modify the final digital manufacturing pattern.

[0105] In practice, the execution of a computer program by a microprocessor allows the final digital manufacturing pattern to be modified via a user interface of the type described above. Also, and as with steps a0) and a'0), the user interface can take the form of a virtual or augmented reality interface, and for example include a virtual or augmented reality headset. The modifications in step i) can be initiated by one or more movements of the user's hand, a remote control, a stylus, or any other element or method that allows actions to be controlled through the virtual or augmented reality interface. For example, the user can create a cutting line on the final digital pattern with a single movement.

[0106] In one embodiment, step i) may include the substeps: i1) Acquire new measurements of the moving body, i2) Extrapolate a new volume from the acquired measurements, i3) Superimpose the final digital manufacturing pattern and the new volume, i4) Modify the final digital manufacturing pattern so that every point of the final digital manufacturing pattern surrounds the volume.

[0107] Another aspect of the invention relates to a garment or bag remarkable in that it is manufactured according to the process that is the subject of the invention. This manufacturing process is particularly suited to the manufacture of modular garments or bags. These are made up of different parts that can be assembled, or not, as desired, so as to adapt the garment to a particular style or occasion.

[0108] Yet another aspect of the invention relates to a computer program characterized in that it is intended to be executed by a microprocessor in such a way as to implement the steps of the manufacturing process of a garment or bag which is the subject of the invention.

[0109] Yet another aspect of the invention relates to an installation for implementing the manufacturing process of a garment or bag that is the subject of the invention. This installation is remarkable in that it comprises: - A microprocessor capable of executing a computer program in order to implement the steps of said manufacturing process, - A computer mass storage device on which said computer program is stored, said mass storage device being configured to store the reference digital pattern (1), the manufacturing digital patterns (3), and the final manufacturing digital pattern, - A user interface configured to display the selected digital manufacturing patterns and allow the selection of one of said digital manufacturing patterns in order to determine the final digital manufacturing pattern from among the selected digital manufacturing patterns, - A digital manufacturing unit configured to manufacture the garment or bag according to the final digital manufacturing pattern.

[0110] According to yet another advantageous feature of the invention enabling a realistic rendering of digital patterns, the user interface includes a virtual reality headset.
