Shock-absorbing Shoe with Movable Outsole Spikes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-slip shoes fail to provide effective shock absorption and stability on both icy and general roads, with existing solutions either compromising on traction when snow or ice is attached or being cumbersome and uncomfortable to wear.
Innovation Solution
A shoe design featuring an outsole with accommodation grooves, support members, movable members, and a resilient member that automatically protrude or retract to absorb shock and maintain traction by adjusting to the ground contact angle, incorporating an auxiliary support member for stability and a recessed contact end for enhanced grip on icy surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spikes are built in the outsole to prevent slipping on ice, then non-slip function is improved, but shock absorption is worsened because spikes do not protrude on paved roads and shock is directly transmitted to the wearer's sole
Solution Approach 1:
The patent applies the dynamics principle by designing movable members that can automatically protrude from or retrieve into the outsole based on the loading conditions. The movable members are equipped with resilient members that enable them to protrude when load is applied during walking, providing non-slip function on icy roads, and retract when no load is applied, preventing shock transmission to the wearer's sole on paved roads.
2Reliability
If anti-skid members are attached to the shoe to prevent slipping, then non-slip function is improved, but ease of operation is worsened because attachment and detachment is cumbersome and comfortable fit is reduced
Solution Approach 1:
The patent applies the merging principle by integrating the anti-skid function directly into the shoe structure through movable members that are built into the outsole. This eliminates the need for separate anti-skid members that need to be attached or detached, providing a comfortable fit while maintaining non-slip function on icy roads.
3Ease of operation
If the outsole is designed to be simple for comfort, then ease of operation is improved, but non-slip function is worsened when snow or ice is attached during walking
Solution Approach 1:
The patent applies the dynamics principle by designing the outsole with movable members that automatically adjust their state based on loading conditions. The movable members protrude when load is applied during walking to provide non-slip function on icy roads, and retract when no load is applied to maintain comfortable fit and simplicity during normal walking.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The shoe effectively absorbs shock and prevents slipping on icy roads while maintaining stability and comfort on general roads, ensuring safe and long-term wear by dynamically adjusting to ground contact and using an auxiliary support member to maintain shape and traction.
Implementation Method 1
a resilient member which is disposed in the first guide portion, of which an upper end comes into contact with a bottom surface of the pressing member, and a lower end comes into contact with a top surface of the latch portion of the movable member
Implementation Method 2
when a load is applied to the outsole during walking, the spikes built in the outsole protrude from a bottom surface of the outsole
