Shoe Sole with Differential Ground Engaging Formations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sports shoes often fail to adequately minimize injuries from twisting and turning movements during collisions in contact or non-contact sports, as existing designs do not sufficiently differentiate traction between the front and rear regions to reduce ankle strain.
Innovation Solution
The shoe sole features a distinct arrangement of ground engaging formations, with a rear array having a lower height or depth than the front array, incorporating elongated protrusions, ribs, or studs that are angled or oriented to facilitate lateral movement and reduce the force required for heel displacement during impacts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the rear array of ground engaging formations has the same height as the front array, then uniform ground engagement is achieved, but the heel cannot move laterally with less force during collisions, increasing ankle strain and injury risk
Solution Approach 1:
The patent applies local quality by differentiating the height of ground engaging formations between the front and rear arrays of the sole. The rear array has a lesser height than the front array, creating localized variation in ground engagement characteristics. This allows the heel to move laterally with less force during collisions while the front maintains strong ground grip, thereby reducing ankle strain and injury risk without compromising overall stability.
2Object-affected harmful factors
If the rear array of ground engaging formations has a lesser height than the front array, then lateral heel movement is facilitated reducing ankle strain, but uniform ground engagement across the sole is compromised
Solution Approach 1:
The patent applies local quality by differentiating the height of ground engaging formations between the front and rear arrays of the sole. The rear array has a lesser height than the front array, creating localized variation in ground engagement characteristics. This allows the heel to move laterally with less force during collisions while the front maintains strong ground grip, thereby reducing ankle strain and injury risk without compromising overall stability.
3Ease of manufacture
If traditional uniform ground engaging formations are used across the entire sole, then manufacturing simplicity is maintained, but injury minimization during twisting and turning movements is insufficient
Solution Approach 1:
The patent applies local quality by differentiating the height of ground engaging formations between the front and rear arrays of the sole. The rear array has a lesser height than the front array, creating localized variation in ground engagement characteristics. This allows the heel to move laterally with less force during collisions while the front maintains strong ground grip, thereby reducing ankle strain and injury risk without compromising overall stability.
Solution Approach 2:
The patent applies segmentation by dividing the sole into distinct front and rear arrays with different ground engaging formation heights. This segmentation allows each region to perform its specific function - the front array provides strong ground grip for propulsion while the rear array facilitates lateral heel movement - thereby improving injury minimization while maintaining manufacturing feasibility through modular design.
