Adaptive Foot Arch Support Shoe With Spring-Elastic Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional shoes lack adequate support for the foot arch, leading to uneven stress distribution and inadequate support during different gaits, with the majority of the weight being concentrated on the front sole and heel, neglecting the foot arch.
Innovation Solution
A shoe design featuring an elastic arch support member with a foot arch support curved surface block, spring body, and elastic straps that adjust support force dynamically to match the foot arch's shape and gait changes, ensuring uniform stress distribution and flexible arch support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional flat insole is used, then the shoe structure is simple, but the foot arch cannot be supported and stress distribution is uneven
Solution Approach 1:
The patent employs dynamic elements including a spring body that compresses and rebounds, and elastic straps that stretch and contract, allowing the foot arch support structure to adapt dynamically to different foot positions and gait phases, transforming from a static flat insole to a dynamic support system
Solution Approach 2:
The support force parameters are changed through the elastic properties of the spring body and elastic straps, which adjust their stiffness and force output based on compression distance and material properties, enabling variable support characteristics throughout the gait cycle
2Device complexity
If a fixed foot arch support pad is used, then the structure is simple, but it cannot adapt to height differences and different gaits
Solution Approach 1:
The support structure transitions from fixed to dynamic through the incorporation of movable components including the spring body that vertically displaces and elastic straps that change tension, enabling real-time adaptation to foot arch height variations and gait-specific requirements
Solution Approach 2:
The elastic straps and spring body form a self-adjusting system that automatically adapts to different foot arch configurations and gait phases without external control, with the elastic elements self-regulating their force output based on their deformation state
3Device complexity
If support weight is concentrated at front sole and heel, then the structure is simple, but the stress area is small and stress distribution is uneven
Solution Approach 1:
The support function is segmented into multiple independent components: the foot arch support curved surface block for arch support, the spring body for vertical cushioning, and multiple elastic straps distributed across the insole, with each segment contributing to overall stress distribution uniformity
Solution Approach 2:
Different regions of the insole are assigned different support characteristics: the foot arch support curved surface block provides localized arch support, while the elastic straps are distributed at specific positions to create localized support zones, achieving uniform overall stress distribution through differentiated local properties

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 design provides adaptive arch support that maximizes stress area uniformity, enhances comfort, and reduces fatigue by dynamically adjusting support force in response to foot arch changes, ensuring consistent support across various activities.
Implementation Method 1
a spring body adapted to an inner bottom of the foot arch support curved surface block, where the spring body and the several elastic straps flexibly adjust a support force at the foot arch jointly
Implementation Method 2
several elastic straps disposed between an outer edge of the foot arch support curved surface block and the interior of the shoe body, where the spring body and the several elastic straps flexibly adjust a support force at the foot arch jointly
