Description

DESCRIPTION

Process for producing a sole that is configured individually for a carrier

shoe

The invention relates to a method for producing a sole for a shoe that is configured individually and at least in sections in a carrier-specific manner.

Such processes for the production of soles for a shoe, at least in sections, individually configured for the wearer of a shoe, are basically known from the prior art.

The soles that can be produced or produced using corresponding methods can in particular serve to compensate for wearer-specific, individual medical-orthopedic foot malpositions and, accordingly, especially from a medical-orthopedic point of view, the wearing properties, ie. H. especially the comfort, the soles improve wearer-specific. However, soles that can be produced or produced using corresponding methods can generally also be produced, ie. H. irrespective of the aspect of compensating for medical-orthopedic foot malpositions, for example through the targeted introduction of stabilizing areas that stabilize the foot, the wearing properties, d. H. especially the comfort, the soles improve.

A common method for producing corresponding individually configured carrier-specific soles provides - sometimes even carried out manually - mechanical processing of a three-dimensional shaped body provided as a semi-finished product, wherein contour-specifically configured carrier regions are formed in the shaped body for producing a individually configured carrier-specific sole, in particular by ablative machining processes .

To date, this production of a sole configured to be carrier-specifically individual has so far been comparatively complex, so that there is a need for a method for producing a sole that is individually configured to a carrier and at least partially customized for a shoe. The invention is therefore based on the object of specifying a method, particularly with regard to efficiency, for producing a sole for a shoe, which is configured individually, at least in sections, in a carrier-specific manner.

The object is achieved by a method for producing a sole for a shoe configured individually and at least in sections for a particular wearer. The dependent claims relate to possible embodiments of the method.

The method described here generally serves to produce a sole for a shoe that is configured at least in sections, possibly completely, in a carrier-specific, individualized manner. An at least partially, possibly completely, individually configured carrier-specific sole is to be understood as meaning a sole configured at least in sections, possibly completely, with respect to a foot of a (later) wearer of the sole to be manufactured or manufactured according to the method or of a shoe equipped with the sole. The sole is in its structure, i. H. in particular in their geometric-constructive shape or design, in particular in the area of their surface facing the foot of a (later) wearer of the sole, and in their structural properties, which may vary locally, i. H. in particular mechanical properties, at least in sections, if necessary completely, on the foot, d. H. in particular the foot morphology of a (later) wearer of the sole adapted. In other words, a sole that can be manufactured or manufactured according to the method has properties that are configured individually, at least in sections, if appropriate, in a completely individual manner.

A sole that can be produced or manufactured according to the method can serve to compensate for wearer-specific medical-orthopedic foot malpositions and, accordingly, in particular from a medical-orthopedic point of view, improved wearing properties, ie. H. in particular have improved comfort. However, with a sole that can be manufactured or manufactured in accordance with the method, it is also possible in general, ie. H. Regardless of the aspect of compensating medical-orthopedic foot deformities, improved wearing properties, d. H. in particular to produce an improved wearing comfort.

Under a sole which can be produced or produced according to the method is in particular one To understand the insole of a shoe or an insole to be inserted into a shoe. A corresponding insole or insole, when assembled with the other components of a shoe, therefore has a position arranged or designed lying between an outsole having a tread or a midsole arranged or formed above a corresponding outsole and a shaft (upper shoe). A method that can be produced or manufactured according to the method is therefore not an outsole or midsole.

The procedure includes the steps described in more detail below:

In a first step of the method, a single-layer or multi-layer sole base body is provided. The sole base body has certain structural properties as well as a certain geometric-constructive basic design or shape, i. H. in particular with regard to a specific shoe size of a shoe, in which shoe the sole is to be arranged, and / or with regard to a last or interior of a shoe in which shoe the sole is to be arranged, adapted dimensions, in particular length dimensions, and a correspondingly adapted one Volume of space. A sole base body that can be provided or provided according to the method typically does not (yet) have any carrier-specifically configured properties. The structural properties or the geometric-constructive basic design of the sole base body are typically chosen independently of the specific foot morphology of a (later) wearer of the sole.

The sole base body is typically created from the geometric-constructive design of a shoe last or on the basis of a corresponding shoe last or on the basis of shoe scan data. It is also conceivable that the sole base body from the geometric-constructive design of a footbed of a reference shoe, i. H. e.g. B. an existing shoe of a (later) wearer of the sole, or on the basis of a corresponding footbed. A footbed can therefore be provided as the sole base body.

The sole base body can be a sole base body manufactured in a conventional manufacturing method, ie not in an additive construction method, so that a sole base body manufactured in a conventional manufacturing method is provided in the first step of the method can. The sole base body can be a preconfigured mass article. In principle, however, it is also conceivable that the sole base body was also manufactured in an additive construction process.

The base body can be provided manually or automatically via a suitable provision device, e.g. B. in the form of an at least partially robotized handling system. Corresponding sole base bodies can therefore be stored in a warehouse or other store, possibly according to various categories, such as, for. B. material, shoe size, etc., ordered, held and automatically provided to carry out the further steps of the method.

In a second step of the method, at least one sole element to be connected or connected to the sole base body, which influences the wearing properties of the sole to be manufactured at least in sections, is additive or generative, i. H. typically built up in layers. Since the wearing properties of the sole typically (also) with the structural properties, i.e. H. In particular the mechanical properties, the geometric-constructive shape or design of a corresponding sole element are correlated, the structural properties, ie. H. especially affect the mechanical properties of the sole.

As mentioned, the at least one, or in the case of several sole elements, at least one sole element is constructed additively or generatively. In principle, any additive construction method can be used for this purpose, so that additive construction methods based on powder (bed), for example. B. selective laser sintering process, selective laser melting process, binder jetting process, jet fusion process, in particular a single or multijet fusion process, etc., or non-powder (bed) based additive build-up processes, such as. B. Fused Deposition Modeling (FDM) process, Fused Filament Fabrication (FFM) process, cladding, digital light processing (DLP) process, liquid composite molding (LCM) process, stereolithography process, etc., is referred.

The selection of an additive construction method used for the production of the at least one sole element can be based on certain selection criteria, such as, for. B. the material of the additive sole element, the geometric-constructive Shaping or design, in particular the degree of complexity of the three-dimensional shaping or design, the sole element to be constructed additively, the surface properties of the sole element to be constructed additively, etc.

In all cases, the at least one sole element to be produced is additively constructed on the basis of construction data that directly or indirectly describes the at least one sole element. With appropriate construction data, it can be, for. B. to deal with CAD data of the sole element to be manufactured or corresponding construction data may include such CAD data. Corresponding construction data can alternatively or additionally also be so-called layer or slice data of the sole element to be produced, or corresponding construction data can include such layer or slice data.

It is essential for the method described here that the construction data are generated on the basis of the morphology of a foot of a (later) wearer of the sole to be produced, directly or indirectly imaging or describing one-dimensional or multidimensional acquisition data of the foot of the (later) wearer of the sole to be manufactured or have been. According to the method, the one-dimensional or multi-dimensional acquisition data of a foot of a (later) wearer of the sole to be produced are included in the construction data to be used for the additive construction of the sole element. The construction data contain information about the foot of a (later) wearer of the sole to be manufactured or its morphology. Corresponding information represents the foot morphology of a (later) wearer of the sole to be produced, at least in sections, possibly completely, directly or indirectly, or describes this at least in sections, optionally completely, directly or indirectly. In other words, according to the method, construction data are used which have been generated on the basis of acquisition data which directly or indirectly depicts or describes the morphology of a foot of a (later) wearer of the sole to be produced.

Corresponding information directly or indirectly contained in the construction data about the foot of a (later) wearer of the sole to be manufactured thus represents the basis for the carrier-specific, individual configuration of a sole that can be manufactured or manufactured according to the method, as corresponding sole elements on the basis of the wearer-specific information contained in the construction data be built additively over the foot of a (later) support of the sole to be produced. It is also conceivable to allow other data, which directly or indirectly relates to the foot of a (later) wearer of the sole to be produced, to be incorporated into the information and thus into the construction data. For example, carrier-specific information about age, gender, any medical diagnoses or indications, etc. can be included in the information and thus in the construction data.

It is also possible to use geometric-constructive data, i.e. H. in particular dimensions, shape, volume, etc., of the sole base body provided in terms of data to be incorporated into the construction data. The construction data can therefore be generated on the basis of the acquisition data of the foot as well as geometrical-constructive data of the sole base body provided.

As mentioned, the acquisition data can directly or indirectly depict or describe the morphology of the foot of a (later) wearer of the sole to be produced. The acquisition data is therefore generally the morphology of the foot of a (later) wearer of the sole to be produced, directly or indirectly imaging or describing data. The acquisition data can be acquired or have been acquired directly or indirectly via various acquisition methods, so that only by way of example on optical acquisition methods, in particular one-, two- or three-dimensional scanning methods, one-, two- or three-dimensional footprint data or projections, one-, two- or three-dimensional sole data or projections, one-, two- or three-dimensional recordings of a, e.g. B. obtained from a footprint, negative of the foot, etc., is referred. Corresponding detection data can also be data from a pressure distribution measurement and / or data from a movement analysis of a foot of a (later) wearer of the sole to be produced, or the detection data can include such. Of course, acquisition data can also be the dimensions (dimensions) of a foot of a (later) wearer of the sole to be manufactured, or the acquisition data can include such.

The at least one additively constructed sole element is detachably or (without damage or destruction) non-detachably connected to the sole base body. In this way, a sole that is configured in a carrier-specific, individually configured manner can be produced or manufactured. The method for producing the sole described here is to be regarded as very efficient insofar as a mass-produced sole base body is connected to at least one sole element that can be individually manufactured or manufactured, so that the component (s) of the sole, that is, the sole element (s), that is dependent on the carrier-specific, individualized configuration of the sole, ie the sole element or elements, are independent of the method are built up by the sole base body and thus manufactured.

Overall, there is thus an improved method for producing a sole for a shoe, which is configured at least in sections, possibly completely, in a carrier-specific, individualized manner.

The acquisition data of the foot of a (later) wearer of the sole can be generated at the location of the additive construction of the at least one sole element or at the location of the manufacture of the sole, so that a local and / or temporal relationship between the generation of the acquisition data and the additive construction of the sole element or the production of the sole is given. It is therefore possible to carry out the creation of the acquisition data, the additive structure of one or more sole elements based on the acquisition data or the construction data generated therefrom, and the connection of the sole element (s) with a sole base body by a (single) service provider.

However, it is also conceivable to generate the acquisition data not at the location of the additive construction of the at least one sole element or at the location of the manufacture of the sole, but at another location, so that there is no spatial and / or temporal relationship between the generation of the acquisition data and the additive Structure of the at least one sole element or the manufacture of the sole is given. The acquisition data can, for example, be transmitted or transmitted in terms of data by a first service provider who (only) takes over the generation of the acquisition data and can be transmitted to a further service provider who (only) takes over the additive construction of the at least one sole element, which is based on the Acquisition data or construction data generated therefrom carries out an additive construction of the at least one sole element, and delivers the additive-built sole element (s) to a further service provider, who (only) takes over the connection of the additively constructed sole element (s) with a sole base body. It is also conceivable to create the acquisition data yourself via a (later) wearer of the sole. The data required for this on the foot of the wearer can e.g. B. via, if appropriate corresponding hardware and / or software technology, mobile devices such. B. smartphones, tablets, laptops, etc. are recorded. The wearer can transmit or transmit the data he has created himself via a data carrier and / or a local or global data network that enables a data connection to at least one service provider who carries out one or more further steps for the production of the sole according to the method.

In connection with the connection of the at least one additively constructed sole element to a corresponding sole base body, there are various possibilities, all of which provide a stable, i.e. H. In particular, the position or position-permanent captive connection of one or more additively constructed sole elements to the sole base body results:

For example, it is possible for the at least one or at least one sole element, in particular directly, to be built up additively on the sole base body, the sole element being connected to the sole base body. This procedure requires the introduction of a sole base body into an additive construction or manufacturing facility, i. H. e.g. B. a 3D printer, so that the additive structure of a corresponding sole element directly on the sole base body, d. H. in particular that of the foot of a (later) wearer of the sole and / or facing surface of the sole base body can take place. In this way, very stable material connections between a respective sole element and a sole base body can be formed, but positive and / or non-positive connections are also conceivable. For an additive construction of the at least one sole element on the sole base body, an exact alignment and positioning of the sole base body in a corresponding additive construction or manufacturing device is typically required in order to ensure an exact additive construction of the at least one sole element with regard to alignment and positioning. In all cases, there is a highly integrated process for producing a sole that is configured individually and at least in sections in a carrier-specific manner.

As an alternative or in addition, it is possible for the at least one or at least one sole element to be constructed separately in an additive construction process and as separate component is positively and / or non-positively and / or cohesively connected to a sole base body. Thus, a corresponding sole element can also be connected to a corresponding sole base body in a separate step, in which a corresponding sole element in a desired alignment and positioning with the sole base body, ie in particular the foot of a (later) wearer of the sole and / or facing surface of the sole base body, is connected. As mentioned, in particular positive and / or non-positive and / or integral connection types, ie for example snap-in, snap-in, clamp, screw, rivet, adhesive, welded connections, etc., come into consideration.

According to the method, an orthopedic functional element and / or a comfort element influencing the wearing properties can be added as an orthopedic, in particular stabilizing or (under) supporting, orthopedic functional element, in particular in a front and / or middle and / or rear area of the sole base body being constructed. Depending on the specific configuration, a sole element can therefore be arranged in the area of the forefoot and / or the midfoot and / or the rear foot. The sole element can therefore act, in particular due to its alignment and / or positioning on the sole base body, in particular from the forefoot and / or the midfoot and / or the rear foot of a wearer of the sole. The effect of a sole element can, as already indicated, also by its structural properties, i.e. H. in particular its mechanical properties, such as. B. hardness, rigidity, etc., as well as be influenced by its specific geometric-constructive shape or design.

Specifically, z. B. a forefoot and / or midfoot and / or rear foot of a wearer of the sole stabilizing or (under) supporting pelotte element can be constructed additively. A corresponding pad element thus represents an example of a sole element.

According to the method, at least one functional layer, in particular a damping layer having special damping properties and / or moisture, in particular foot sweat, absorbing moisture absorption layer and / or a stabilizing layer which stabilizes the position and / or orientation of the at least one sole element on the sole base body, can be adjusted to one in the worn state Sole exposed surface of the sole facing the foot of a wearer, in particular of the sole base body and / or of the at least one sole element. The functionality of a sole which can be produced or produced according to the method can be expanded by connecting a corresponding functional layer, ie, for example, a damping layer, moisture absorption layer, stabilizing layer, etc., in a targeted manner, specifically for the wearer. Of course, the sole can also comprise several differently functionalized functional layers. Any of the above-mentioned functional layers can be connected to the sole base body via form-fitting and / or non-positive and / or integral connection types, so that reference is made to the above-mentioned explanations in connection with the connection of a sole element to the sole base body.

As mentioned, the selection of a suitable additive construction method for the additive construction of the at least one sole element on the basis of certain selection criteria, such as e.g. B. the material of the additive sole element to be built. In this context it should be mentioned that a sole element can in principle be additively constructed from any single or multi-component material that can be processed in an additive construction process, so that reference is only made to metal, plastic, rubber, cork, etc. by way of example. In a version made of plastic, the sole element can in particular, for. B. from one, in particular thermosetting or thermoplastic, such as. B. polyamide (PA), polyether ether ketone (PEEK), can be built up additively. In addition to the use of synthetic plastics, the use of natural plastics or polymers is also conceivable.

The invention also relates to a sole made according to the method described herein. As mentioned, the sole produced according to the method has, at least in sections, possibly completely, individually configured properties specific to the wearer. All statements in connection with the method for producing a sole described herein apply analogously to the sole.

The invention also relates to a method for producing a shoe. When the shoe can be manufactured according to the method, it can be an open or at least partially closed women's, men's or children's shoe, e.g. B. act in the form of an everyday or sports shoe.

The process for manufacturing a shoe is characterized by the following steps: Providing at least one sole manufactured according to the method for manufacturing a sole described herein,

- Attaching or connecting the sole provided on or with an outsole and / or a midsole and / or a shoe upper (upper shoe) while forming the shoe.

All statements in connection with the method for manufacturing a sole described herein apply analogously to the method for manufacturing a shoe described herein.

The invention also relates to a shoe made according to the method described herein. All statements in connection with the method for manufacturing a shoe described herein apply analogously to the shoe.

The invention is explained in more detail below on the basis of exemplary embodiments in the drawings. It shows:

1 shows a basic illustration of a flowchart for producing a sole 1 configured for a wearer specifically for a shoe according to one exemplary embodiment. The method described in connection with FIG. 1 and the other FIG. Serves to produce a sole 1 for a shoe 2 that is configured at least in sections, possibly completely, in a carrier-specific, individual manner (cf. the basic illustration according to FIG. 9). Under a sole 1 configured at least in sections, possibly completely, in a carrier-specific, individual manner, a sole is configured with respect to a foot of a (later) wearer of the sole 1 to be produced or manufactured according to the method or a shoe 2 equipped with the sole 1, at least in sections, possibly completely Understand sole 2. The sole 2 is in its structure, ie in particular in its geometric-constructive shape or design, in particular in the area of its surface facing the foot of a (later) wearer of the sole 1, and in its structural properties, which may vary locally, that is to say in particular mechanical properties, at least in sections, possibly completely, adapted to the foot, ie in particular the foot morphology, of a (later) wearer of the sole 1. A sole 2 that can be produced or manufactured according to the method thus has properties that are configured completely, carrier-specifically and individually, at least in sections.

A sole 1 that can be manufactured or manufactured according to the method can serve to compensate for wearer-specific medical-orthopedic malpositions of the foot and, accordingly, in particular from a medical-orthopedic point of view, improved wearing properties, ie. H. in particular have improved comfort. However, with a sole 2 that can be produced or manufactured according to the method, H. Regardless of the aspect of compensating medical-orthopedic foot deformities, improved wearing properties, d. H. in particular to produce an improved wearing comfort.

A sole 2 that can be produced or manufactured according to the method is to be understood in particular as an inner sole of a shoe 2 or an insole to be inserted into a shoe 2. A corresponding insole or insole, when assembled with the other components of a shoe 2, has a position arranged or formed between an outsole 4 having a tread 3 or a midsole 5 arranged or formed above a corresponding outsole and a shaft 6 (upper shoe) on.

The procedure includes the steps described in more detail below: In a first step S1 of the method, a single-layer or multi-layer sole base body 7 is provided. 2, 3, each of which shows a basic illustration of an exemplary embodiment of a sole base body 7 in a perspective view, it can be seen that the sole base body 7 has certain structural properties and a certain geometrical-constructive basic design or shape, ie in particular with regard to a certain shoe size of a shoe, in which shoe the sole is to be arranged, and / or with regard to a last or interior of a shoe, in which shoe the sole is to be arranged, has adapted dimensions, in particular length dimensions, and a correspondingly adapted volume of space. The sole base body 7 does not (yet) have any carrier-specific, individually configured properties. The structural properties or the geometric-constructive basic design of the sole base body are selected independently of the specific foot morphology of a (later) wearer of the sole 1.

The sole base body 7 can be created from the geometric-constructive design of a shoe last or on the basis of a corresponding shoe last. It is also conceivable that the sole base body 7 from the geometric-constructive design of a footbed of a reference shoe, i. H. e.g. B. an existing shoe of a wearer, or on the basis of a corresponding footbed. A footbed can therefore be provided as the sole base body 7.

The sole base body 7 is typically a in a conventional manufacturing process, i. H. typically not in an additive construction process, manufactured sole base body 7, so that in the first step S1 of the method, a sole base body 7 manufactured in a conventional manufacturing method is typically provided. The sole base body 7 can be a preconfigured mass article. In principle, however, it is also conceivable that the sole base body 7 was manufactured using an additive construction method.

The sole base body 7 can be provided manually or automatically via a suitable provision device (not shown), e.g. B. in the form of an at least partially robotized handling system. Thus, sole base body 7 in a warehouse or other storage, possibly according to various categories, such as. B. material, shoe size, etc., ordered, held and to carry out the further steps of Procedures are provided automatically.

In a second step S2 of the method, at least one sole element 8 to be connected or connected to the sole base body 7, which influences the wearing properties of the sole to be manufactured at least in sections, is constructed additively or generatively. Since the wearing properties of the sole 1 typically also have the structural properties, i.e. H. In particular, the mechanical properties and / or the geometrical-structural shape or design of the sole element 8 are correlated, the structural properties, ie. H. in particular affect the mechanical properties of the sole 1.

The at least one, or in the case of a plurality of sole elements 8, at least one sole element 8 is, as mentioned, constructed additively or generatively. In principle, any additive build-up method can be used for this, so that additive build-up methods based on powder (bed), for example B. selective laser sintering process, selective laser melting process, binder jetting process, jet fusion process, in particular a single or multijet fusion process, etc., or non-powder (bed) based additive build-up processes, such as. B. Fused Deposition Modeling (FDM) process, Fused Filament Fabrication (FFM) process, cladding, digital light processing (DLP) process, liquid composite molding (LCM) process, stereolithography process, etc., is referred.

The selection of an additive construction method used for the production of a sole element 8 can be based on certain selection criteria, such as, for. B. the material of the additive sole element 8, the geometric-constructive shape or design, in particular the degree of complexity of the three-dimensional shape or design, the additive sole element 8, the surface quality of the additive sole element 8, etc., take place.

In this context, it should be mentioned that a sole element 8 can in principle be additively constructed from any single- or multi-component material that can be processed in an additive construction process, so that reference is only made to metal, plastic, rubber, cork, etc. by way of example. In a design made of plastic, the sole element 8 can in particular, for. B. from one, especially thermosetting or thermoplastic, Plastic, such as B. polyamide (PA), polyether ether ketone (PEEK), can be built up additively. In addition to the use of synthetic plastics, the use of natural plastics or polymers is also conceivable.

In all cases, the sole element 8 to be produced is additively constructed on the basis of construction data directly or indirectly describing the sole element 8. With appropriate construction data, it can be, for. B. to deal with CAD data of the sole element 8 to be manufactured or corresponding construction data may include such CAD data. Corresponding construction data can alternatively or additionally also be so-called layer or slice data of the sole element 8 to be produced, or corresponding construction data can include such layer or slice data.

It is essential for the method described here that the construction data are based on the one-dimensional or multi-dimensional acquisition data of the foot of the (later) wearer of the sole 1 to be produced, which directly or indirectly maps or describes the morphology of a foot of a (later) wearer of the sole 1 to be manufactured are generated or have been. According to the method, the one-dimensional or multi-dimensional acquisition data of a foot of a (later) wearer of the sole 1 to be manufactured are included in the construction data to be used for the additive structure of the sole element 8. The construction data contain information about the foot of a (later) wearer of the sole 1 to be produced or its morphology. Corresponding information depicts the foot morphology of a (later) wearer of the sole 1 to be produced, at least in sections, possibly completely, directly or indirectly, or describes it at least in sections, optionally completely, directly or indirectly.

Corresponding information contained directly or indirectly in the construction data about the foot of a (later) wearer of the sole 1 to be produced thus represents the basis for the carrier-specific, individual configuration of a sole 1 that can be produced or produced according to the method, as corresponding sole elements 8 on the basis of the construction data contained carrier-specific information about the foot of a (later) wearer of the sole 1 to be manufactured can be built up additively.

It is also conceivable to enter other data directly or indirectly into the data relating to the foot of a (later) wearer of the sole 1 to be manufactured To let information and thus flow into the construction data. For example, carrier-specific information about age, gender, any medical diagnoses or indications, etc. can be included in the information and thus in the construction data.

It is also possible to use geometric-constructive data, i.e. H. in particular dimensions, shape, volume, etc., of the sole base body 7 provided to be incorporated into the construction data. The construction data can therefore be generated on the basis of the acquisition data of the foot as well as geometric-constructive data of the sole base body 7 provided.

As mentioned, the acquisition data can directly or indirectly depict or describe the morphology of the foot of a (later) wearer of the sole 1 to be produced. The acquisition data are accordingly the morphology of the foot of a (later) wearer of the sole 1 to be produced, which directly or indirectly depicts or describes data. The acquisition data can be acquired or have been acquired directly or indirectly via various acquisition methods, so that only by way of example on optical acquisition methods, in particular one-, two- or three-dimensional scanning methods, one-, two- or three-dimensional footprint data or projections, one-, two- or three-dimensional sole data or projections, one-, two- or three-dimensional recordings of a, e.g. B. obtained from a footprint, negative of the foot of a (later) wearer of the sole 1 to be produced, etc., is referred. Corresponding acquisition data can also be data from a pressure distribution measurement and / or data from a movement analysis of a foot of a (later) wearer of the sole 1 to be produced, or they can be

Collection data include such. Of course, the acquisition data can also be the dimensions (dimensions) of a foot of a (later) wearer of the sole 1 to be produced, or the acquisition data can include such.

A corresponding additively constructed sole element 8 is detachably or non-detachably (without damage or destruction) connected to the sole base body 7 in a third step S3 of the method. In this way, a sole 1 configured specifically for the wearer can be manufactured or manufactured. The method for producing the sole 1 is to be regarded as very efficient insofar as a sole base body 7 that can be provided or is provided as a mass article is connected to at least one sole element 8 that can be individually manufactured or manufactured, so that the person or persons who individualized the wearer The configuration (s) of the sole 1 that determines the component (s) of the sole 1, ie the sole element (s) 8, is constructed and thus manufactured independently of the sole base body 7.

The acquisition data of the foot of a (later) wearer of the sole 1 can be generated at the location of the additive construction of the at least one sole element 8 or at the location of the manufacture of the sole 1, so that there is a local and / or temporal relationship between the generation of the acquisition data and the additive Structure of the sole element 8 or the manufacture of the sole 1 is given. It is therefore possible to carry out the creation of the acquisition data, the additive structure of one or more sole elements 8 based on the acquisition data or the construction data generated therefrom, and the connection of the sole element or elements 8 with an additive structure to a sole base body 7 by a (single) service provider .

However, it is also conceivable not to generate the acquisition data at the location of the additive construction of the at least one sole element 8 or at the location of the manufacture of the sole 1, but at another location, so that there is no local and / or temporal relationship between the generation of the acquisition data and the additive structure of the at least one sole element 8 or the manufacture of the sole 1 is given. For example, the acquisition data can be created or transmitted by a first service provider, who (only) takes over the generation of the acquisition data, and can be transmitted or transferred to another service provider, who (only) takes over the additive construction of the at least sole element 8, which is based on the Acquisition data or construction data generated therefrom carries out an additive construction of the at least one sole element 8, and delivers the additive-built sole element 8 to a further service provider, who (only) takes over the connection of the additively constructed sole element 8 with a sole base body 7.

It is also conceivable to create the acquisition data yourself via a (later) support of the sole 1. The data required for this on the foot of the wearer can e.g. B. via, if appropriate corresponding hardware and / or software technology, mobile devices such. B. smartphones, tablets, laptops, etc. are recorded. The carrier can transmit or transmit the self-created acquisition data to at least one service provider via a data carrier and / or a local or global data network that enables a data connection, which service provider carries out one or more further steps process of manufacturing the sole 1.

In connection with the connection of the at least one additively constructed sole element 8 to a corresponding sole base body 7, there are various possibilities, all of which provide a stable, i.e. H. In particular, the position or position-permanent captive connection of one or more additively constructed sole elements 8 to the sole base body 7 results:

For example, it is possible for the at least one or at least one sole element 8 to be built up additively on the sole base body 7, the sole element 8 being connected to the sole base body 7. This procedure requires the introduction of a sole base body 7 into an additive construction or manufacturing device, i. H. e.g. B. a 3D printer, so that the additive structure of a corresponding sole element 8 directly on the sole base body 7, d. H. typically the surface of the sole base body 7 facing the foot of a (later) wearer of the sole 1 can take place. In this way, very stable integral connections between a sole element 8 and a sole base body 7 can be formed, but positive and / or non-positive connections are also conceivable. For an additive construction of the at least one sole element 8 on the sole base body 7, a precise alignment and positioning of the sole base body 7 in a corresponding additive construction or manufacturing device is required in order to ensure an exact additive construction of the sole element 8 with regard to alignment and positioning.

As an alternative or in addition, it is possible for the at least one or at least one sole element 8 to be separately constructed in an additive construction method and to be connected to a sole base body 7 in a positive and / or non-positive and / or integral manner as a separate component. A corresponding sole element 8 can therefore also be connected to a corresponding sole base body 7 in a separate step, in which a corresponding sole element 8 has a desired orientation and positioning with the sole base body 7, ie typically that of the foot of a (later) wearer of the sole 1 facing surface of the sole base body 7, is connected. As mentioned, in particular positive and / or non-positive and / or integral connection types, ie for example snap-in, snap-in, clamp, screw, rivet, adhesive, welded connections, etc., come into consideration. 4 to 7 show purely exemplary different exemplary embodiments of a respective sole element 8. It can be seen from FIGS. 4 to 7 that a sole element to be arranged, in particular in a front and / or middle and / or rear area of the sole base body 7, an orthopedic, in particular stabilizing or (supporting) supportive, orthopedic functional element and / or a comfort element influencing the wearing properties are constructed additively on the foot of a wearer. Depending on the specific configuration, a sole element 8 can therefore be arranged in the area of the forefoot and / or the midfoot and / or the rear foot. The sole element 8 can thus act, in particular due to its alignment and / or positioning on the sole base body 7, in particular from the forefoot and / or the midfoot and / or the rear foot of a wearer of the sole 1. The effect of a sole element 8 can, as already indicated, also by its structural properties, ie in particular its mechanical properties, such as. B. hardness, rigidity, etc., as well as be influenced by its specific geometric-constructive shape or design.

4 shows a top view of an embodiment of a sole element 7 in the form of a support or pelotte element supporting the forefoot in the area of the toes.

5 shows a top view of an exemplary embodiment of a sole element 7 in the form of a support or pelotte element which supports the midfoot or the arch of the foot.

6 also shows a top view of an embodiment of a sole element 7 in the form of a support or pelotte element supporting the midfoot or the arch of the foot.

7 shows a top view of an exemplary embodiment of a sole element 7 in the form of a support or pelotte element which supports the rear foot or the verses.

4 - 7 it can be seen that as the sole element 8 z. B. a forefoot and / or midfoot and / or rear foot of a wearer of the sole 1 stabilizing or (under) supporting support or pad element can be constructed additively.

8 shows, in a top view, purely by way of example, an exemplary embodiment of a sole 1 produced according to the method, comprising a sole base body 7 with a A plurality of sole elements 8 arranged thereon and correspondingly connected thereto and acting on different areas of the foot of a wearer of the sole 1.

According to the method, as indicated by way of example in FIG. 9, at least one functional layer 9, in particular a damping layer having special damping properties and / or moisture, in particular foot sweat, absorbing moisture absorption layer and / or one or more of the at least one sole element 8 in its position and / or orientation the sole base body 7 stabilizing stabilizing layer, to an exposed surface of the sole 1, in particular the sole base body 7 and / or the at least one sole element 8, facing the foot of a wearer when the sole 1 is worn. The functionality of the sole 1 can be achieved by connecting an appropriate functional position, i.e. H. e.g. B. a damping layer, moisture absorption layer, stabilization layer, etc., can be expanded specifically carrier-specific individualized. Of course, the sole 1 can also comprise several differently functionalized functional layers 9. The connection of any of the above-mentioned functional layers 9 to the sole base body 7 can take place via form-fitting and / or non-positive and / or integral connection types, so that in this regard reference is made to the above analogous statements in connection with the connection of a sole element 8 to the sole base body 7 becomes. Adhesive or welded connections are particularly suitable.

A sole 1 produced according to the described method can be used in the production of a shoe 2. The shoe 2 can be an open or at least partially closed women's, men's or children's shoe, e.g. B. act in the form of an everyday or sports shoe.
