Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Surfboard riders experience skin chafing and knee catching due to loose-fitting boardshorts, which restrict movement and increase the risk of accidents, and current developments focus more on comfort rather than performance enhancement.

Innovation Solution

A technical pant garment with an inner short that fits tightly and an outer short that fits loosely, featuring resistance and tension sections to realign the wearer into a correct posture, improving stance, balance, and muscle strength through load application, providing feedback on posture deviations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If boardshorts are made loose-fitting to provide freedom of movement, then comfort is improved, but skin chafing and knee catching occur due to fabric friction

Engineering Contradiction:

Improvefreedom of movementVSAvoidskin chafing

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The boardshort is divided into multiple functional panels with different stretch characteristics. The inner panel has higher stretch to reduce skin friction, while the outer panel provides structural support. This segmentation allows different regions of the garment to serve different functions, reducing chafing while maintaining freedom of movement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different panels of the boardshort are constructed with different fabric properties and stretch levels tailored to specific body regions. The inner panel uses more elastic material for areas prone to chafing, while outer panels use more durable materials for areas requiring support and abrasion resistance.

Inventive Principle:

Principle #3Local quality

2Ease of operation

If boardshorts are made loose-fitting to provide freedom of movement, then comfort is improved, but the fabric catches the knees increasing accidents

Engineering Contradiction:

Improvefreedom of movementVSAvoidaccident reduction

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The boardshort incorporates dynamic stretch properties that adapt to movement. The fabric stretches more in directions corresponding to surfing movements, allowing freedom of movement, while maintaining tension in directions that prevent fabric from catching on knees during transitions.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If stretch fabrics are used to reduce movement restriction, then comfort is improved, but the garment lacks performance enhancement for muscle strength and posture

Engineering Contradiction:

4Productivity

If the inner short is made tight-fitting to provide posture correction, then performance is improved, but comfort may be reduced

Engineering Contradiction:

Solution Approach 1:

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The garment utilizes changes in fabric stretch parameters and tension forces to provide posture correction. The inner panel's elastic properties create gentle tension that guides the wearer into proper stance without the discomfort of rigid compression, adapting to different body positions during surfing.

AI summary

A technical pant garment 10 having an inner short 11 and an outer short 12. The inner short 11 is formed to tightly fit a wearer of the garment 10 and the outer short 12 is connected to the inner short 11 to fit loosely about the inner short 11. The inner short 11 is constructed to impose on or more leads on the wearer which act to affect the posture of the wearer in a manner tending to cause the wearer who has adopted an incorrect posture to realign towards a correct posture.
