Shoe Tread Sole with Nested Stabilizing Overshoes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shoe solutions fail to provide adequate stability for the ankle and midfoot, particularly in the elderly, and do not effectively correct specific postural defects such as pronation or supination.
Innovation Solution
A shoe tread sole with inner and outer receiving surfaces configured to hold stabilization compensating overshoes, which attach via attachment portions and provide additional stability by compensating for postural defects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional shoe soles are used, then the shoe structure remains simple, but the ankle and midfoot stability is insufficient
Solution Approach 1:
The patent implements nested stabilizing elements where inner and outer stabilizing elements are positioned at different depths within the sole structure. The inner stabilizing elements are embedded in the midsole while outer stabilizing elements extend to the outsole, creating a nested configuration that provides multi-level support for the ankle and midfoot without excessive complexity
Solution Approach 2:
The sole is segmented into multiple functional zones with distinct stabilizing elements positioned at specific locations. The stabilizing elements are divided into inner and outer components with different geometries and depths, allowing targeted stabilization of the ankle and midfoot regions while maintaining overall sole integrity
2Adaptability or versatility
If conventional shoe soles are used, then the manufacturing process remains simple, but specific postural defects such as pronation or supination cannot be corrected
Solution Approach 1:
The patent applies local quality by providing different stabilizing element geometries and configurations at different locations within the sole. Inner stabilizing elements have specific geometries tailored for pronation correction while outer stabilizing elements are configured for supination correction, allowing targeted correction of specific postural defects without requiring complete sole redesign
Solution Approach 2:
The stabilizing elements are designed with dynamic characteristics that allow them to adapt to different gait patterns and postural conditions. The elements can deform and respond to applied forces, providing active correction of pronation and supination during the gait cycle rather than rigid static support
3Reliability
If existing stabilization solutions are used, then some stability improvement is achieved, but the ankle and midfoot stability remains insufficient
Solution Approach 1:
The patent adds a vertical dimension to stabilization by positioning stabilizing elements at different depths within the sole structure. Inner stabilizing elements are embedded at midsole depth while outer stabilizing elements extend to the outsole surface, creating a three-dimensional stabilization system that provides superior ankle and midfoot support compared to single-plane solutions
