Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current footwear manufacturing methods find it difficult to incorporate individualized or customized components that provide tailored performance characteristics, such as flexure, hardness, and support, specific to a user's foot, which is particularly challenging for athletes or individuals with injuries or disorders.
Innovation Solution
The method involves creating a customized last using 3D scan data and pressure readings to design and manufacture a midsole element and lasting, which are then integrated with a moldable material to form a customized sole, ensuring precise fit and performance characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional footwear manufacturing methods are used, then production efficiency is maintained, but the ability to incorporate individualized or customized components is limited
Solution Approach 1:
The patent applies preliminary action by creating customized lasts and midsole elements before the footwear assembly process. Individualized components are manufactured in advance based on user-specific data (3D scans, pressure readings), then integrated into the molding process. This allows customization without disrupting the overall manufacturing workflow, as the customized components are prepared separately and then incorporated into the assembly.
Solution Approach 2:
The patent segments the footwear manufacturing process into distinct stages: creating customized lasts, manufacturing midsole elements, assembling components in molds, and injecting elastomer. By dividing the process into separable steps with standardized interfaces, the system can incorporate individualized components at specific stages without requiring complete process reconfiguration, thus managing complexity while enabling customization.
2Manufacturing precision
If customized components are incorporated, then performance characteristics are tailored to user needs, but manufacturing difficulty increases
Solution Approach 1:
The patent uses copying by creating accurate digital representations of user feet through 3D scanning and pressure mapping. These digital models serve as precise templates for manufacturing customized lasts and midsole elements. The copying process captures exact foot geometry and pressure distribution patterns, enabling high-precision customization without requiring manual measurement and fabrication for each user.
Solution Approach 2:
The patent applies parameter changes by varying physical properties of materials (elastomer hardness, flexibility, density) and geometric parameters (midsole thickness, curvature, support zone dimensions) based on user-specific data. These parameter adjustments are made systematically according to measured foot characteristics and performance requirements, enabling precise tailoring of footwear properties while maintaining standardized manufacturing processes.
3Reliability
If data-driven design is used, then footwear performance is optimized for individual users, but manufacturing time and complexity increase
Solution Approach 1:
The patent performs data collection, analysis, and component design in advance before the actual footwear manufacturing. User foot data is gathered and processed beforehand to create customized lasts and midsole elements. This preliminary preparation ensures that when manufacturing begins, all design decisions are already made, eliminating time-consuming adjustments during production and enabling efficient manufacturing of optimized footwear.

AI summary
Example shoe manufacturing methods and related computer readable medium for implementing a portion of said manufacturing methods are disclosed herein. In some examples, the method includes producing a lower portion of a last based on data relating to a foot of a user. In addition, the method includes placing an upper member about the last such that a lasting of the upper member extends over the lower portion of the last. Further, the method includes producing a midsole element based on the data relating to the foot of the user, and attaching the midsole element to the upper member such that the lasting is disposed between the lower portion of the last and the midsole element.
