Shoes may be manufactured according to industry standard sizes for mass production. Using industry standard sizes is likely to accommodate a high percentage of the customer base.
Some examples of the present application are described with respect to the following figures:
Variations in foot sizes (e.g., length and width) exist among individual customers. Thus, a customer's foot size may not match well with an industry standard size, leading to an uncomfortable fit of the shoe.
Examples described herein provide a system to manufacture a customized component of shoe based on customer data. For example, a shaping device may be attached to a physical last to define a component of shoe for customization. The component may be manufactured using the last. The shaping device may be a fitting that is generated based on three dimensional (3D) scan data of a foot of a customer and pressure data associated with the foot of the customer. In another example, a shaping device may encompass a region of a physical last. The shaping device may include a set of actuators to customize the last by defining a shape of the region based on 3D scan data of a foot of a customer and pressure data associated with the foot of the customer. In another example, a set of actuators may be located within a physical last. A deployment of the set of actuators to define a shape of a region of the last may be based on 3D scan data of a foot of a customer and pressure data associated with the foot of the customer. Examples described herein may increase efficiency of manufacturing customized shoe.
System 100 may include a physical last 102. Physical last 102 may be a physical device that is in the shape of a human foot. During operation, system 100 may receive three-dimensional (3D) scan data 104 of a foot of a customer and/or pressure data 106 associated with the foot of the customer. 3D scan data 104 may be measurements of the foot obtained using a 3D foot scanner. 3D scan data 104 may be used to create a 3D digital representation of the foot. Pressure data 106 may indicate pressure distribution experienced by the foot. Pressure data 106 may include both static pressure data (e.g., when the customer is standing still) and dynamic pressure data (e.g., when the customer is in motion). Pressure data 104 may be obtained using a pressure sensor. Based on 3D scan data 104 and pressure data 106, physical last 102 may be modified so that a component of a shoe manufactured using physical last 102 is customized for the particular customer. Modifying physical last 102 to manufacture a customized component of a shoe for a particular customer is described in more detail in
In an example, shaping device 204 may be a piece of fitting generated based on 3D scan data 104 and/or pressure data 106. Shaping device 204 may be manufactured in a plurality of manners. In an example, a digital representation of shaping device 204 may be determined from 3D scan data 104 and/or pressure data 106. The digital representation of shaping device 204 may include dimensions of shaping device 204 (e.g., length, width, depth, height, etc.). The digital representation of shaping device 204 may be used to manufacture shaping device 204 via a subtractive manufacturing process, an additive manufacturing process, a molding process, or a combination thereof.
In some examples, an additive manufacturing process may include a 3D printing process. The digital representation of shaping device 204 may be sent to a 3D printer for manufacturing. In some examples, in a subtractive manufacturing process, shaping device 204 may be first manufactured having standard dimensions (e.g., via an additive manufacturing process). Shaping device 204 may be cut or trimmed to custom dimensions based on the digital representation of shaping device 204 in a milling machine. In some examples, the digital representation of shaping device 204 may be used to create a mold for injection molding. The mold may be used to create shaping device 204.
Once manufactured, shaping device 204 may be attached to a bottom region 206 of housing 202. For example, shaping device 204 may be attached to bottom region 206 via magnets, clips, screws, etc. When shaping device 204 is attached to bottom region 206, housing 202 with shaping device 204 may be used to create a component of a shoe that is customized for a particular customer.
Shaping device 204 may also be attached to other regions of housing 202, which is described in more detail in
During operation, shaping device 300 may receive shaping information 314 that defines a shape of bottom region 312. Shaping information 314 may be determined using 3D scan data 104 and/or pressure data 106. Based on shaping information 314, controller 308 may control a deployment of set of actuators 310. As an example, controller 308 may activate an actuator 316 of set of actuators 310 to define the shape of bottom region 312 by deforming a portion of bottom region 312. When the shape of bottom region 312 is defined, shaping device 300 may be detached from housing 304. Shaped physical last 302 may be used to manufacture a component of a shoe that is customized for a particular customer.
During a molding process, such as an injection molding process, a molding device 500 may be used to form a component of a shoe using physical last 102. Molding device 500 may include a housing 502 may include a cavity 504 that receives a portion of housing 202 to define a mold. For example, a portion of 202 may be encompassed by housing 502 such that bottom region 206 of housing 202 is encompassed by cavity 504. Thus, remaining space in cavity 504 (not taken up by housing 202) may define a mold for a component of a shoe. Molding device 500 may also include an injection machine 508. Housing 502 may include an opening 510 to receive a tip 512 of injection machine 508.
Injection machine 508 may determine how a component of a shoe is formed based on injection instructions 514. Injection instructions 514 may be determined based on 3D scan data 104 and/or pressure data 106. For example, injection machine 508 may, based on injection instructions 514, vary the speed and/or pressure of the material injected over time to change a property of the material. Thus, a first region of a component may be formed using a material having a first property. A second region of the component may be formed using the material with a second property different from the first property. The resulting component may have material properties that vary along a gradient depending on the speed and/or pressure of the material injected. As another example, injection machine 508 may inject different materials to form the component. Injection machine 508 may inject a first material during a first time period to form a first region of the component. Injection machine 508 may inject a second material during a second time period to form a second region of the component. Thus, the resulting component may be formed using different materials.
Computing device 600 may include a processor 602 and a computer-readable storage medium 604. Processor 602 may include a central processing unit (CPU), a semiconductor-based microprocessor, and/or other hardware devices suitable to control operations of computing device 600. Computer-readable storage medium 604 may be any electronic, magnetic, optical, or other physical storage device that contains or stores executable instructions. Thus, computer-readable storage medium 604 may be, for example, Random Access Memory (RAM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a storage device, an optical disc, etc. In some examples, computer-readable storage medium 604 may be a non-transitory storage medium, where the term “non-transitory” does not encompass transitory propagating signals. As described in detail below, computer-readable storage medium 604 may be encoded with a series of processor executable instructions 606 and 608.
Data receiving instructions 606 may receive 3D scan data, such as 3D scan data 104, and/or pressure data, such as pressure data 106. Physical last customization determination instructions 608 may determine a modification to be applied to a physical last based on the 3D scan data and/or the pressure data received using data receiving instructions 606. For example, the modification may include dimensions of shaping device 204. As another example, the modification may include a digital representation of shaping device 204. As another example, the modification may include shaping information 314.
