Torsion Control Bridge in Golf Shoe Sole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Shoes used in sporting activities, such as golf, lack sufficient stability, traction, and torsion control to effectively manage the complex forces exerted during movements, leading to reduced performance and increased foot fatigue.
Innovation Solution
The design incorporates a shoe structure with a torsion control bridge, a wrap-around wire support system, and a reel-based lacing system, featuring distinct materials for sole portions and traction elements to enhance arch support, stability, and flexibility, allowing for customizable fit and improved torsional control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a torsion control bridge is added to connect front and heel sole portions, then torsional control and stability are improved, but device complexity increases
Solution Approach 1:
The sole is divided into separate front and heel portions that are not fully connected, allowing independent movement and rotation. This segmentation enables the front and rear portions to move independently during the golf swing, reducing unwanted torsion while maintaining natural foot flexibility.
Solution Approach 2:
Different regions of the shoe have different levels of flexibility and support. The midfoot area features a rigid bridge structure for torsional control, while the forefoot and heel areas maintain flexibility for natural movement. This localized differentiation optimizes both stability and adaptability.
2Stability of the object's composition
If wrap-around wire support is implemented, then arch support and stability are improved, but device complexity increases
Solution Approach 1:
The wire support system is divided into multiple segments that wrap around different parts of the foot, including the arch and heel areas. These segmented wire elements work together to provide distributed support rather than a single rigid structure, reducing complexity while maintaining effectiveness.
Solution Approach 2:
The wire support elements are thin, flexible components that conform to the foot's shape while providing structural support. These thin-film-like wire elements offer arch support without adding significant bulk or complexity to the shoe construction.
3Stability of the object's composition
If distinct materials with different rigidity are used for sole portions, then traction and stability are improved, but manufacturing complexity increases
Solution Approach 1:
Different materials are applied to different regions of the sole based on specific functional requirements. The forefoot area uses materials optimized for flexibility and ground feel, while the heel and midfoot areas use materials providing traction and structural support. This localized material differentiation improves performance without requiring complex multi-material construction throughout the entire sole.
