Shoe Sole Reinforcing Bar Layout for Sport-Specific Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe designs with a single reinforcing structure member limit the ability to adjust performance according to specific usage, such as athletic events, leading to suboptimal design and functionality.
Innovation Solution
A shoe sole with a reinforcing structure comprising two distinct reinforcing members, the first and second reinforcing members, each with bars extending in different directions and materials, allowing for adjustable rigidity to enhance performance based on usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single reinforcing member is used in the midsole, then the structure is simple and easy to manufacture, but the ability to adjust performance according to specific usage is limited
Solution Approach 1:
The single reinforcing member is divided into multiple separate reinforcing members (first reinforcing member with first bar, second reinforcing member with second bar). Each bar can be independently configured in terms of position, orientation, and dimensions, enabling customized performance adjustment for different athletic uses while maintaining relatively simple manufacturing processes.
2Adaptability or versatility
If multiple reinforcing members with different configurations are used, then performance can be adjusted for specific athletic events, but the device complexity increases
Solution Approach 1:
Different reinforcing members are positioned at specific locations within the midsole (first bar on one side, second bar on another side) with different orientations and configurations tailored to local structural needs. This allows performance optimization for specific athletic events without requiring complete redesign of the entire shoe structure.

AI summary
A shoe sole includes a sole body, and a reinforcing structure portion made up of a first reinforcing member and a second reinforcing member that are made of different members from each other. The first reinforcing member includes a first bar, and the second reinforcing member includes a second bar. The first bar is located on a medial foot side from the second bar. A portion of the first bar disposed in a midfoot portion extends along an oblique direction crossing both a front-rear direction and a left-right direction, and a portion of the second bar disposed in the midfoot portion extends crossing the left-right direction. The portion of the first bar disposed in the midfoot portion and the portion of the second bar disposed in the midfoot portion are located at least in part with a distance therebetween.
