Segmented Arch Support Insole for Foot Shock Absorption

Solution Overview

Problem

Conventional arch support insoles fail to adequately absorb shock and provide sufficient support to the arch and heel areas of the foot during walking, leading to fatigue and pain due to limited cushioning and impact absorption.

Innovation Solution

An arch support insole with a soft flexible body featuring a palm support portion, an arch support portion, and a heel support portion, designed with specific angles and contours to conform to the foot's shape, made from materials like TPR, TPE, or silicone, providing ergonomic support and enhanced cushioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional rubber materials are used for arch support insole, then cushion effect is provided, but impact absorption ability is limited

Engineering Contradiction:

Improveimpact absorption abilityVSAvoidcushion effect limitation

Core Design Contradiction:

StrengthVSReliability

Solution Approach 1:

The insole is divided into three distinct support portions: heel support portion (40-60mm from rear end), arch support portion (above midfoot), and palm support portion (above forefoot). Each portion is positioned to target specific high-impact areas of the foot, distributing shock absorption across multiple zones rather than relying on uniform material properties throughout the entire insole.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The insole employs varying thickness across different regions: the heel support portion has thickness of 3-5mm, arch support portion has 1-3mm, and palm support portion has 2-4mm. This localized variation in thickness and material distribution optimizes cushioning effectiveness in high-impact areas while maintaining overall flexibility and comfort.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If traditional insole without midfoot support is used, then shoe structure is simple, but foot fatigue occurs due to lack of arch support

Engineering Contradiction:

Improvefoot comfortVSAvoidinsole structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The insole is divided into three distinct support portions: heel support portion (40-60mm from rear end), arch support portion (above midfoot), and palm support portion (above forefoot). Each portion is positioned to target specific high-impact areas of the foot, distributing shock absorption across multiple zones rather than relying on uniform material properties throughout the entire insole.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The single insole structure simultaneously provides heel cushioning, arch support, and forefoot comfort through its integrated three-portion design. This multi-functional approach addresses multiple foot support needs (shock absorption, arch maintenance, fatigue reduction) within one unified component, avoiding the need for multiple separate devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Strength

If insole with enhanced shock absorption is designed, then impact protection is improved, but insole thickness increases

Engineering Contradiction:

Improveshock absorptionVSAvoidinsole thickness

Core Design Contradiction:

StrengthVSLength of stationary object

AI summary

An arch support insole includes a basic body made from soft flexible material having a top surface, a palm support portion and an arch support portion, wherein the palm support portion has a rear part, a front part with a width gradually increased from said rear part, an arched lateral side conforming to an arch of human foot, a topmost planar surface and a curved side surface gradually descending from the topmost planar surface. The topmost planar area is spaced apart from the top surface of the basic body at 7 mm˜9 mm. The arch support portion surrounds the rear part and the curved side surface of the palm support portion, has an upwardly curved top surface with a topmost point which is spaced from the top surface of the basic body at 1 mm˜4 mm.
