Partial Spherical Cap Arch Support for Foot Pain Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insoles either lack sufficient support to improve posture or become uncomfortable when worn for extended periods due to stiffness, failing to address the growing issues of back, knee, and foot pain caused by poor posture.
Innovation Solution
An insole design featuring a partial spherical cap arch support section made of ultra-high molecular weight polyethylene, with a flexible and adhesive bottom surface, providing enhanced arch support and comfort by distributing weight more evenly and conforming to the foot's shape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional over-the-counter insoles with cushioned or gel-like pads are used, then user comfort is improved, but sufficient support to improve posture is not provided
Solution Approach 1:
The insole implements different local qualities by providing a rigid longitudinal arch support section that extends from the heel to the toe area, while other portions of the insole maintain cushioning properties. This localized rigidity in the arch support region provides the necessary posture support without compromising overall comfort in other areas of the foot.
2Reliability
If corrective insoles with sufficient arch support are prescribed, then posture support is improved, but user comfort deteriorates when worn for extended periods due to stiffness
Solution Approach 1:
The insole implements different local qualities by providing a rigid longitudinal arch support section that extends from the heel to the toe area, while other portions of the insole maintain cushioning properties. This localized rigidity in the arch support region provides the necessary posture support without compromising overall comfort in other areas of the foot.
3Reliability
If the arch support section is made rigid to provide sufficient support, then posture improvement is achieved, but comfort during extended wear deteriorates
Solution Approach 1:
The insole implements different local qualities by providing a rigid longitudinal arch support section that extends from the heel to the toe area, while other portions of the insole maintain cushioning properties. This localized rigidity in the arch support region provides the necessary posture support without compromising overall comfort in other areas of the foot.
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 insole improves posture, balance, and comfort by reducing pressure on joints and increasing the contact area, thereby alleviating lower back fatigue and foot pain while allowing for easy fitting into various shoe sizes.
Implementation Method 1
the bottom surface of the insole is disposed with an adhesive
Implementation Method 2
a partial spherical cap arch support section made of ultra-high molecular weight polyethylene, with a flexible and adhesive bottom surface, providing enhanced arch support and comfort by distributing weight more evenly and conforming to the foot's shape

AI summary
An insole is provided. This insole features a front end, a thickness, a top surface, a bottom surface, a heel receiving portion having a first end and a second end, a lateral longitudinal arch support section which has a width, and a medial longitudinal arch support section. Preferably, the medial longitudinal arch support section is made up of a partial spherical cap which has a radius and a height, and the medial longitudinal arch support section runs from the first end of said heel receiving portion to the lateral longitudinal arch support section.
