Segmented Energy Return Sole with Flexion Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional footwear designs fail to provide adequate cushioning, stability, and energy return, which are essential for high-performance athletic shoes, as they lack an effective energy absorption and return system.
Innovation Solution
The energy sole system, which includes a base structure, flexion, toe arm, and heel arm, is designed to absorb and return energy through elastic and rigid materials, providing enhanced cushioning and stability by compressing and rebounding during foot motion, and can be integrated into shoe designs or used as a standalone component.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional rubber soles and mid-soles are used, then basic cushioning is provided, but energy return and stability are insufficient
Solution Approach 1:
The sole is divided into multiple functional segments: a base structure for support, flexion elements for energy storage, toe arms and heel arms for directional stability. Each segment performs a specific function, allowing the system to simultaneously provide energy return and stability that conventional monolithic soles cannot achieve.
Solution Approach 2:
The invention uses composite construction combining rigid materials (for the base structure and arms) with flexible elements (for the flexion portions). This composite approach enables the sole to deliver both the stability provided by rigid structures and the energy return provided by flexible, spring-like elements.
2Strength
If pressurized pockets or coil springs are added to the heel, then cushioning is improved, but device complexity increases
Solution Approach 1:
The flexion elements are integrated directly into the base structure as a unified component rather than separate add-on elements. This merging of the cushioning mechanism with the structural base simplifies the overall design compared to conventional approaches that use separate pressurized pockets or coil springs, while still providing effective cushioning through the flexion action.
3Productivity
If an energy absorption and return system is implemented, then performance is improved, but manufacturing complexity increases
Solution Approach 1:
The invention achieves energy return by changing the geometric parameters of the flexion elements (curvature, thickness, material properties) rather than using complex mechanical mechanisms. By optimizing these parameters, the sole provides efficient energy return while maintaining relative simplicity in manufacturing, as the flexion elements can be formed as integral parts of the sole structure.
