Shoe Sole Reinforcing Bar Layout for Usage-Specific Stability
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 composed of multiple members, including a first and second reinforcing member, each with distinct rigidity, positioned to provide enhanced support and stability across the forefoot, midfoot, and rearfoot regions, allowing for adjustable 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 reinforcing members (first reinforcing member and second reinforcing member), each with different rigidity characteristics and positional arrangements. This segmentation allows independent optimization of each member's properties to suit specific athletic usage requirements while maintaining manufacturing feasibility.
2Adaptability or versatility
If multiple reinforcing members with different rigidity are used, then performance can be tailored for various athletic activities, but the device complexity increases
Solution Approach 1:
Different reinforcing members are positioned at specific locations within the midsole (first reinforcing member in forefoot portion, second reinforcing member in rearfoot portion) with different rigidity properties tailored to local functional requirements. This local quality approach enables performance optimization for specific athletic activities without requiring complex overall structural changes.

AI summary
A shoe sole (100A) includes a sole body (110), and a reinforcing structure portion (120) made up of a first reinforcing member (120A) and a second reinforcing member (120B) that are made of different members from each other. The first reinforcing member (120A) includes a first bar (122A), and the second reinforcing member (120B) includes a second bar (122B). The first bar (122A) is located on a medial foot side from the second bar (122B). A portion of the first bar (122A) disposed in a midfoot portion (R2) extends along an oblique direction crossing both a front-rear direction and a left-right direction such that a front end thereof is located on a lateral foot side and a rear end thereof is located on the medial foot side, and a portion of the second bar (122B) disposed in the midfoot portion (R2) extends crossing the left-right direction such that a front end thereof is located on the lateral foot side. The portion of the first bar (122A) disposed in the midfoot portion (R2) and the portion of the second bar (122B) disposed in the midfoot portion (R2) are located at least in part with a distance therebetween.
