Non-stretch Inner Layer for Thigh Separation in Garments

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing garments fail to effectively address thigh chafing by not reducing the root cause of friction between thighs, leading to symptoms like inflammation, blister-like lesions, and pain, which can hinder exercise routines and lead to skin infections.

Innovation Solution

A shape-enhancing garment featuring a base layer and inner compressive layers with a non-circumferential, non-stretch layer that applies pressure to the inner thigh area, urging tissue away and providing a thigh slimming and separation effect, thereby reducing friction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If garments with flat or no seams are worn, then symptoms of thigh chafing are addressed, but the root cause of friction between thighs is not eliminated

Engineering Contradiction:

Improvesymptoms of thigh chafingVSAvoideffectiveness in preventing thigh chafing

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The non-circumferential non-stretch layer applies preliminary compressive force to separate the thighs before friction can occur, preventing the root cause of chafing rather than merely addressing symptoms after contact happens

Inventive Principle:

Principle #9Preliminary anti-action

2Reliability

If a non-circumferential non-stretch layer is added to provide thigh slimming and separation, then the root cause of thigh chafing is addressed, but the garment structure becomes more complex

Engineering Contradiction:

Improveeffectiveness in preventing thigh chafingVSAvoidgarment structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The non-circumferential non-stretch layer is strategically positioned only in the inner thigh region where chafing occurs, rather than making the entire garment non-stretch, thus providing targeted functionality with minimal added complexity

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The garment combines different material properties by integrating a non-stretch layer within a stretch base layer, creating a composite structure that provides both compression and flexibility where needed

Inventive Principle:

Principle #40Composite materials

3Reliability

If a non-stretch layer is used to provide powerful urging effect, then thigh separation is increased, but the garment adds bulk and reduces aesthetics

Engineering Contradiction:

Improvethigh separation effectVSAvoidgarment bulk and aesthetics

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The non-circumferential non-stretch layer is constructed as a thin film that provides the necessary compressive force without adding significant bulk, maintaining a streamlined appearance while delivering effective thigh separation

Inventive Principle:

Principle #30Flexible shells and thin films

AI summary

A shape enhancing garment which is formed from a base layer and one or more inner compressive layers for applying pressure at least to an inner thigh area to urge inner thigh leg tissue away from the inner thigh; wherein the one or more inner compressive layers comprise a non-circumferential layer; wherein the non-circumferential layer is a non-stretch layer and reduces thigh chafing.
