Shoe Sole Segmentation and Coupling for Pedaling Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shoes lack a cost-effective design that allows for easy attachment and detachment of components while providing reliable support for both pedaling human-powered vehicles and walking, with limited breathability and ventilation.
Innovation Solution
The shoe design incorporates an upper, an inner plate, and an outer plate with a coupling mechanism, including a male screw portion and female screw portion for secure attachment, along with air ventilation openings and a breathable mesh material for improved ventilation and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional shoes use a single-layer sole structure, then manufacturing is simple, but they lack reliable support for both pedaling and walking
Solution Approach 1:
The sole is divided into an inner plate and an outer plate as separate components. The inner plate provides structural support for pedaling while the outer plate provides ground contact for walking. This segmentation allows each plate to be optimized for its specific function while maintaining overall structural integrity.
Solution Approach 2:
The dual-plate design creates a multi-functional sole structure where the inner plate serves pedaling functions (providing rigidity and cleat mounting surface) while the outer plate serves walking functions (providing ground contact and flexibility). This universal design enables the shoe to perform both cycling and walking activities effectively.
2Ease of operation
If components are permanently bonded, then structural integrity is high, but ease of attachment and detachment is poor
Solution Approach 1:
The coupling members enable dynamic attachment and detachment of the inner and outer plates. Users can securely attach the plates when needed for support, and easily detach them for maintenance or replacement. This dynamic system transitions between secured and separated states based on operational requirements.
Solution Approach 2:
Coupling members act as intermediary elements between the inner plate and outer plate. These coupling members provide the mechanical connection that secures the plates together during use, while allowing for controlled detachment when needed. The intermediaries enable both reliable attachment and easy operation.
3Ease of manufacture
If traditional uppers are used, then manufacturing is simple, but breathability and ventilation are limited
Solution Approach 1:
The upper incorporates porous or mesh materials that provide breathability and ventilation while maintaining structural integrity. These porous materials allow air flow through the upper, reducing heat buildup and improving comfort during physical activities like cycling and walking.

AI summary
A shoe is basically provided with an upper, an inner plate, an outer plate and a first coupling member. The upper has a toe end, a heel end and a bottom portion extending between the toe end and the heel end in a longitudinal direction. The inner plate is removably disposed on an upper side of the bottom portion. The outer plate has a contact portion configured to contact at least one of a cleat and a pedal. The outer plate is disposed on a bottom side of the bottom portion. The first coupling member is configured to couple the inner plate and the outer plate.
