Description

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 methods of manufacturing such fashion articles. State of the art

[0002] We know fashion items such as clothing, bags, etc. Generally speaking, the creative process for a garment or bag is as follows. A designer, or stylist, begins by designing a pattern for the garment or bag; this is the design stage. Then, a prototype of the garment or bag is made by cutting, then, by assembling, for example by sewing, different pieces of fabric, leather, or other materials according to the pattern; this is the prototyping stage. If necessary, modifications to the pattern are made to obtain a definitive pattern; this is the development stage. Several prototyping stages may take place during the development phase to validate the various modifications. Finally, when the model is selected, the garment or bag is manufactured industrially, by cutting and assembling different pieces of fabric, leather, or other materials according to the final pattern; this is the manufacturing stage. When the model is not selected, the pattern is discarded or destroyed.

[0003] However, the creative process, which includes many steps, is generally long and costly. In particular, the prototyping stage requires very expensive skilled labor. 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 make the costs related to the creative process profitable, the garment or bag is generally offered in large series. Therefore, the garment or bag is designed to be worn by the greatest number of people without being adapted to the morphology of each individual.

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

[0006] This makes it possible to quickly create a large number of digital patterns according to criteria adapted to the customer. Therefore, it is possible to create a garment or bag without having to manufacture a plurality of physical patterns. The use of raw materials is then greatly reduced. The same is true for the time and costs required for the creative process. The use of knitted textiles, and / or non-woven textiles, and / or knitted material, and / or non-woven material, and / or knitted textile fiber, and / or non-woven textile fiber, and / or polymer fiber, at the garment or bag manufacturing stage avoids any waste of raw materials.

[0010] According to yet another advantageous characteristic of the invention making it possible to dispense with the prototyping step, the pattern placement step and the grading step of the garment or bag, step g) comprises the 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 characteristic of the invention making it possible to ensure that the garment or bag is adapted to the morphology of a user, step g) comprises the steps: gl) Displaying, 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 inside the three-dimensional rendering three dimensions of the garment or bag, g2) Retrieve a choice of the final digital pattern entered via a user interface.

[0012] According to yet another advantageous characteristic of the invention making it possible to create a usable history of the choices made by the user(s), the method comprises the step: j) Recording correlation data between the at least one selection criterion established and the final digital manufacturing pattern.

[0013] According to yet another advantageous characteristic of the invention making it possible to gradually improve the selection of digital patterns by an automatic learning method, step f) comprises the following steps: fl) Comparing the at least one selection criterion with each previously recorded correlation data, f2) Selecting from the database at least two digital manufacturing patterns for which the at least one selection criterion corresponds to the previously recorded correlation data.

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

[0015] The clothing or bag is thus better adapted to the customer's criteria and obtained in a shorter 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 so as to implement the steps of the method of manufacturing 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 garment or bag suitable for a person skilled in the art. The garment or bag is obtained by assembling at least two pieces together. A piece may be made of fabric, leather, synthetic material, or any other material suitable for a person skilled in the art. The different pieces may be made of the same material or different materials. The assembly may be carried out by sewing, meshing, buttoning, Velcro, felting, textile fiber projection, or any other assembly means suitable for a person skilled in the art.

[0026] The manufacturing method which is the subject of the invention comprises the step: a) Recording a digital reference pattern (1) for the manufacture of a garment or bag comprising a set of digital points.

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

[0028] A digital pattern is presented in the form of a set of digital points. The digital points are arranged in a two- or three-dimensional digital space. These digital points form one or more digital lines, straight or curved, assembled together so as 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 presented in the form of a set of digital points, the latter forming one or more digital lines, straight or curved, assembled together so as to generate the digital shape of parts of the garment or bag, the assembly of the digital shapes of said parts making it possible to obtain the digital shape of said clothing 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 a basis for creating a complete digital pattern. In certain embodiments, the reference digital pattern (1) may be in the form of a complete digital pattern. As in the exemplary 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 of the hard disk (HDD), solid-state disk (SSD) type, or any other computer mass storage medium suitable for those skilled in the art.

[0031] Prior to recording, 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 digital pattern to be imported.

[0032] In an alternative embodiment, prior to recording, the digital reference pattern (1) may be generated by means of a user interface and a computer program executed by a microprocessor. The computer program may, for example, be of the computer-aided drawing (CAD) software type, computer-aided design (CAD) software, or any other computer program suitable for a person skilled in the art. The user interface may be composed of a graphical interface displayed by a screen and an active interface comprising, alone or in combination, a keyboard, a mouse, a touch screen, a stylus or any other active interface suitable for a person skilled in the art. In practice, the user traces the digital lines of the digital reference pattern (1) by means of the user interface. 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 recording, the reference digital pattern (1) can be, as desired, 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 variant embodiment, prior to step a), the manufacturing method which is the subject of the invention may comprise the steps: a01) Acquiring measurements of a stationary body, a02) Generating a digital reference pattern (1) from the acquired measurements.

[0035] In step a0l), the measurements of the stationary body may be carried out by means of 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 may be positioned on a stationary body and the position of the sensors in space can be recorded. In one embodiment, the body scanner may be in the form of a video volumetric capture device, for example of the Azure Kinect type. In yet another embodiment, the body scanner may be in the form of a photo-based volumetric capture device. In yet another embodiment, the body scanner may be in the form of a radar volumetric capture device.

[0036] In step a02), the generation of the reference digital pattern (1) may comprise the following substeps: a021) Extrapolating a volume from the acquired measurements, a022) Creating an envelope surrounding the volume, a023) Optionally modifying one or more determined parts of the envelope, for example to add functional clearances at the level of the parts facing the joints of the body, a024) Determining one or more assembly zones of the envelope so as to create the reference digital pattern (1).

[0037] In practice, the execution of a computer program by a microprocessor allows the implementation of step a02) and its sub-steps. The software may, 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 joints of the body. In alternative embodiments, the user may initiate modifications in step a023) via a user interface of the type described previously. The user interface may also be in the form of a virtual or augmented reality interface, and for example comprise a virtual or augmented reality headset.The modifications in step a023) may be initiated by one or more movements of the user's hand, a remote control, a stylus or any other element or manner allowing actions to be controlled through the virtual or augmented reality interface.

[0038] In step a), the manufacturing method which is the subject of the invention may also comprise the step: a1) Determining from among the digital points of the reference digital pattern (1) a set of fixed digital points of fixed position.

[0039] In step a), the manufacturing method which is the subject of the invention may also comprise the step: a2) Determining among the digital points of the reference digital pattern (1) variable digital 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 rest of the 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 variable digital points of variable position, the rest of the points being fixed digital points of fixed position. reference (1) the fixed digital point(s) of fixed position, the rest of the 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 be in the form of a virtual or augmented reality interface, and for example comprise a virtual or augmented reality headset. The selection of the fixed digital points, and / or the variable digital points, can be carried out by one or more movements of the user's hand, a remote control, a stylus or any other element or manner making it possible to control actions through the virtual or augmented reality interface.

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

[0042] In an alternative embodiment, the manufacturing method which is the subject of the invention may also comprise the step: a') Generating 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) correspond 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 include more, fewer, or the same number of digital points as the reference digital pattern (I). 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 exemplary 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 reference digital pattern (2) may not comprise any part in common with the reference digital pattern (1). In alternative embodiments, the additional reference digital pattern (2) may comprise at least one part in common with the reference digital pattern (1). The at least one part in common may take the form of a digital point or a digital line. As in the exemplary embodiment shown in figure [Fig.3], the additional reference digital pattern (2) may comprise: - A first digital line (21) in common with a first digital line (II) of the reference digital pattern (1), - A second digital line (22) in common with a second digital line (12) of the reference digital pattern (1), - Three digital points (51, 52, 53) in common with the reference digital 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 recording, 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 method which is the subject of the invention may comprise the steps: a' 01) Acquiring measurements of the body in motion, a' 02) Generating an additional reference digital pattern (2) from the acquired measurements.

[0049] It is therefore possible to create a garment or bag that is better suited to the consumer's body shape without having to make a plurality of physical patterns.

[0050] In step a'01), the measurements of the moving body may be carried out using a three-dimensional (3D) body scanner such as those available on the market or by any other means suitable for those skilled in the art. In particular, sensors may be positioned on a moving body, and the successive positions of the sensors in space may be recorded. In one embodiment, the body scanner may be in the form of a video volumetric capture device, for example of the Azure Kinect type. In yet another embodiment, the body scanner may be in the form of a volumetric capture device from photos. In yet another embodiment, the body scanner may be in the form of a radar volumetric capture device. The volume delimited by the moving body is thus necessarily larger than the volume delimited by the immobile body.In addition, the acquisition of measurements on a moving body makes it possible to generate an additional digital reference pattern (2) particularly suited to the dynamics of the body.

[0051] In step a'02), the generation of the additional digital reference pattern (2) may comprise the following sub-steps: a' 021) Extrapolate a volume from the acquired measurements, a' 022) Create an envelope surrounding the volume, a' 023) Optionally modify one or more determined parts of the envelope, for example to add functional clearances at the level of the parts facing the joints of the body, a' 024) Determine one or more assembly zones of the envelope in order to create the additional digital reference pattern (2).

[0052] In practice, the execution of a computer program by a microprocessor allows the implementation of step a'02) and its sub-steps. The software may, in particular, be configured to determine in step a'023) the parts of the envelope to be modified, for example the parts of the envelope arranged opposite the joints of the body. In alternative embodiments, the user may initiate modifications in step a'023) via a user interface of the type described above. The user interface may also be in the form of a virtual or augmented reality interface, and for example comprise a virtual or augmented reality headset. In particular, the interface may comprise a means for displaying a three-dimensional rendering of the pattern, within which a three-dimensional rendering of the body in motion extrapolated from the measurements acquired in step a'01) may be displayed.The modifications in step a'023) may be initiated by one or more movements of the user's hand, a remote control, a stylus or any other element or manner allowing actions to be controlled through the virtual or augmented reality interface.

[0053] When the method comprises the generation of an additional digital reference pattern (2), the manufacturing method which is the subject of the invention can then comprise the step: a' 1) Determine among the digital points of the additional digital reference pattern (2) a set of fixed digital points of fixed position.

[0054] In step a'), the manufacturing method which is the subject of the invention may also comprise step: a' 2) Determining among the digital points of the additional digital reference pattern (2) variable digital points of variable position.

[0055] As for 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 the fixed digital points and / or the variable digital points is carried out in a similar way to the way described previously for the reference digital pattern (1) using the same type of interface.

[0056] The manufacturing method which is the subject of the invention also comprises 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 the at least two fixed digital points.

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

[0058] When the method comprises the generation of an additional digital reference pattern (2), the manufacturing method which is the subject of the invention may also comprise 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 the at least two fixed digital points.

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

[0060] When the method comprises the generation of an additional digital reference pattern (2), the modified position of at least a portion of the variable digital points is such that the digital manufacturing pattern (3) extends in a space (4) delimited by the minimum generation envelope and the maximum generation envelope. Referring to the 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 digital manufacturing patterns. The space (4) includes its boundaries, i.e. 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 a portion of the variable digital points is such that said additional digital manufacturing pattern extends in a space (4) delimited by the minimum generation envelope and the maximum generation envelope.

[0062] In alternative embodiments, the modified position of at least a portion of the variable digital points is such that the digital manufacturing pattern (3) extends at least partly outside the space (4) delimited by the minimum generation envelope and the maximum generation envelope. Similarly, the modified position of at least a portion of the variable digital points may be such that the additional digital manufacturing pattern extends at least partly 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 comprise 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) comprises more digital points than the reference digital pattern (1). When the reference digital pattern (1) comprises, in addition to the set of fixed digital points, variable digital points, the digital manufacturing pattern (3) may comprise 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 may be merged.Similarly, when two initially close numerical points are moved apart, additional numerical points. can be created. In addition, digital lines connecting at least two fixed digital points can be generated, in addition to changing the position of at least some of the variable digital points.

[0064] In the embodiment of the 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 the space (4) exists, all the digital lines of the digital manufacturing pattern (3) can be included in the space (4). In other words, all the digital lines of the digital manufacturing pattern (3) are included 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 digital manufacturing pattern (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 included in space (4). In other words, all the digital lines of the digital manufacturing pattern (3) are included 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 parts in common 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 with which a function is associated. For this function to exist, it is important to preserve the shape and dimensions of this part. The part of the garment or bag may, for example, be an armhole, a neckline, or other. The part of the garment or bag may also correspond to a part capable of interconnecting with other garments or bags.This is particularly the case when a garment or bag is modular and may consist of an assembly of different sub-items of clothing or bag. In particular, the reference digital pattern (1), and possibly the additional reference digital pattern (2), may be configured so that at least some modular clothing 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 allows the generation of the digital manufacturing pattern (3). The latter 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" is meant that the computer program generates the digital manufacturing pattern (3) autonomously, that is to say, without user intervention. Preferably, the computer program comprises a supervised or unsupervised learning algorithm allowing the generation of the digital manufacturing pattern (3). The unsupervised learning algorithm can in particular be of the "generative adversarial networks" type (or "GANs" for short).

[0071] The manufacturing method which is the subject of the invention also comprises the step: c) Recording the digital manufacturing pattern (3) in a database.

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

[0073] The manufacturing method which is the subject of the invention also comprises 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 determined 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 determined 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 method which is the subject of the invention also comprises the step: e) Establishing at least one selection criterion.

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

[0077] The at least one selection criterion can be established in different ways. According to a first exemplary embodiment, step e) can comprise the step: el) Retrieve at least one criterion entered via a user interface.

[0078] The user interface is of the same type as the user interface previously described. The entry of at least one criterion can be done by entering one or more keywords in a text box, by selecting one or more pre-recorded criteria via check boxes, radio buttons, drop-down menus, or other graphical interface components suitable for those skilled in the art. These criteria can include body dimensions. They can also include terms relating to the shape of the garment or bag such as long, short, fitted, loose, etc. They can also include terms relating to the use: sport, chic, leisure, work, etc.

[0079] According to a second exemplary embodiment, step e) may comprise the step: e2) Acquiring body measurements.

[0080] The acquisition of body measurements may be carried out by means of 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. The body scanner may in particular be of the type previously described.

[0081] According to a third exemplary embodiment, step e) may comprise the 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 certain exemplary embodiments, step e) may comprise 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 recovery of at least one criterion entered via a user interface according to step e1).

[0084] The manufacturing method which is the subject of the invention also comprises 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 exemplary embodiment, one or more typical criteria can be associated with one or more digital patterns in the database.

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

[0090] In alternative embodiments, the method may comprise, in addition to step f), the step: f) Selecting, from the database, at least one additional digital manufacturing pattern corresponding to at least one selection criterion.

[0091] The manufacturing method which is the subject of the invention also comprises the step: g) Determining the final digital manufacturing pattern from among the selected digital manufacturing patterns and possibly the selected additional digital manufacturing patterns.

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

[0093] To do this, step g) may include the 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 display of the three-dimensional rendering of the garment or bag. The computer program is of the conventional software three-dimensional rendering engine type well known to those skilled in the art. The entry of the choice of the final digital pattern can be done by a mouse click on the rendering, or on a button on the graphical interface, or by any other selection means suitable to those skilled in the art.

[0095] In an alternative embodiment, step g) may comprise the steps: gl) Displaying, 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) Retrieving a choice 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 the display of a three-dimensional rendering of body measurements. The superposition of the renderings makes it possible to visually ensure that the proposed digital manufacturing pattern is suitable for the person's morphology.

[0097] Advantageously, the method may comprise the step: j) Recording 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 find this final digital manufacturing pattern which clearly corresponds to the criteria and is therefore a relevant proposition for the user. In practice, the execution of a computer program by a microprocessor makes it possible to record the correlation data in a database arranged on a computer mass storage medium of the type previously described. The correlation data may comprise several data, in particular a “criteria” data item comprising the established selection criterion(s) and a “pattern” data item corresponding to a link to the final digital manufacturing pattern.

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

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

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

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

[0103] To do this, the final digital manufacturing pattern can be sent to a digital manufacturing unit. The latter can then carry out, partially or entirely, the steps necessary for the manufacture of the garment or bag, in particular the cutting(s) of materials, then the assembly, for example by means of seams, etc. Preferably, the digital manufacturing unit carries out entirely the steps necessary for the manufacture of the garment or bag. This avoids the steps of pattern placement and scaling as well as all the associated calculations, these steps and calculations being traditionally implemented when using two-dimensional patterns. The manufacturing unit can comprise a three-dimensional printer and / or a textile fiber projection machine and / or a numerically controlled weaving machine and / or a numerically controlled non-woven machine and / or a machine of textile mesh 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 bag suitable to a person skilled in the art. Preferably, the production unit comprises a three-dimensional printer and / or a textile fiber projection machine and / or a numerically controlled weaving machine and / or a textile mesh machine and / or a numerically controlled felting machine, so as to avoid any cutting and allow the production of clothing while avoiding the production of any raw material waste. 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 manufacturing line is then configured according to the final digital manufacturing pattern.The production line may comprise a weaving machine and / or a non-woven machine and / or a felting machine and / or a textile cutting machine and / or a sewing machine, or any other means of manufacturing clothing or bags suitable to a person skilled in the art. The clothing or bag is then manufactured on the production line thus configured.

[0104] The manufacturing method which is the subject of the invention may also comprise, 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 modification of the final digital manufacturing pattern via a user interface of the type previously described. Also, and as for steps a0) and a'0), the user interface may be in the form of a virtual or augmented reality interface, and for example comprise a virtual or augmented reality headset. The modifications 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 manner making it possible to control actions through the virtual or augmented reality interface. For example, the user may create a cutting line on the final digital pattern with one movement.

[0106] In an alternative embodiment, step i) may comprise the sub-steps: 11) Acquire new measurements of the body in motion, 12) Extrapolate a new volume from the acquired measurements, 13) Superimpose the final digital manufacturing pattern and the new volume, 14) 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 that is remarkable in that it is manufactured according to the method that is the subject of the invention. This manufacturing method is particularly suitable for the manufacture of modular garments or bags. The latter are broken down into 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 so as to implement the steps of the method of manufacturing 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 method of manufacturing a garment or bag which is the subject of the invention. This installation is remarkable in that it comprises: - A microprocessor capable of executing a computer program so as to implement the steps of said manufacturing process, - A computer mass memory on which said computer program is recorded, said mass memory being configured to record the reference digital pattern (1), the digital manufacturing patterns (3), and the final digital manufacturing pattern, - A user interface configured to display the selected digital manufacturing patterns and allow the selection of one of said selected digital manufacturing patterns so as 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 characteristic of the invention allowing a realistic rendering of the digital patterns, the user interface comprises a virtual reality headset.
