Pivoting Heel Shoe Mechanism for Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern humans walk predominantly on hard surfaces, causing repeated trauma to the heel bone due to its evolutionary mismatch, and current shoes fail to address this issue effectively, leading to instability and health concerns.
Innovation Solution
A shoe with a pivoting heel that shifts between flat and pivot positions, utilizing a spring-loaded mechanism to absorb impact and distribute weight more evenly, thereby reducing trauma and improving stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed heel structure is used in shoes, then manufacturing is simple and cost-effective, but it causes repeated trauma to the heel bone when walking on hard surfaces
Solution Approach 1:
The heel structure is transformed from a fixed rigid component to a dynamic pivoting mechanism that can rotate between a flat position during walking and a pivot position during impact. This dynamic structure allows the heel to adapt its orientation based on the gait cycle, distributing impact forces more effectively and reducing trauma to the heel bone while maintaining manufacturing feasibility through standardized pivot joint components
2Object-affected harmful factors
If a pivoting heel mechanism is added to absorb impact, then trauma to the heel bone is reduced, but the device complexity increases
Solution Approach 1:
The pivoting heel mechanism is segmented into distinct functional components: an upper plate attached to the shoe body, a lower plate contacting the ground, and a pivot joint connecting them. This segmentation allows each component to be optimized independently and assembled using standard mechanical parts, reducing overall complexity while maintaining the impact-absorbing function through the relative rotation between plates
3Stability of the object's composition
If the heel is kept flat on the ground for stability, then walking stability is improved, but impact shock is not absorbed effectively
Solution Approach 1:
The heel structure dynamically transitions between a flat configuration during the loading phase of walking (providing stability) and a pivoted configuration during impact (absorbing shock). The pivot joint enables this dynamic reorientation, allowing the heel to maintain ground contact for stability while rotating to dissipate impact forces through the spring-loaded mechanism

Function Achieved in This Case
The pivoting heel acts as a shock absorber, reducing the impact of heel strikes and enhancing stability by distributing weight across a larger surface area, thereby minimizing trauma to the knee and hip and preventing falls.

AI summary
A shoe with an integrally attached pivoting heel. The pivoting heel would rock back and forth between a pivot position and a flat position as a wearer of the shoe walks. The pivoting heel can have an upper plate connected to a lower plate via a rod, wherein the upper plate can rotate about the rod relative to the lower plate (or vice-versa). The pivoting heel can provide the wearer with more stability while the user walks and can help prevent slipping and falling.
