3D Textile Groin Venting in Lower-Body Garments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lower-body garments fail to provide adequate ventilation during strenuous activities, leading to discomfort and sweating.
Innovation Solution
A lower-body garment featuring a 3D textile with openings in the groin area, sandwiched between outer and inner layers, which stretches and compresses with movement to create air flow, combined with an adjusting system for a secure fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a traditional lower-body garment is used during strenuous activities, then the garment provides basic coverage and comfort, but the ventilation is insufficient leading to sweating and discomfort
Solution Approach 1:
The patent applies porous materials by incorporating a 3D textile with through-going openings in the groin covering portion. This 3D textile acts as a porous structure that allows air to pass through, significantly improving ventilation in the area most affected by sweating during strenuous activities. The porous nature of the 3D textile directly addresses the ventilation deficiency of traditional garments.
Solution Approach 2:
The garment is segmented into different portions with different functions: a groin covering portion with 3D textile for ventilation, and other portions with traditional 2D textile for coverage. This segmentation allows the garment to provide enhanced ventilation where needed most while maintaining overall structural integrity and coverage, resolving the contradiction between ventilation improvement and structural complexity.
2Ease of manufacture
If the garment structure is simplified for ease of manufacture, then production becomes easier, but the ventilation performance deteriorates
Solution Approach 1:
The 3D textile with through-going openings is integrated into the groin covering portion as a functional element that can be manufactured using standard textile processes. The porous structure is built into the fabric itself rather than requiring complex assembly, maintaining ease of manufacture while achieving superior ventilation performance.
Solution Approach 2:
The garment combines 3D textile (porous material) with traditional 2D textile in a composite structure. The 3D textile layer provides ventilation functionality while the 2D textile provides coverage and structural support. This composite approach allows both ventilation performance and manufacturability to be maintained.
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
Enhances comfort by improving ventilation and moisture evacuation, reducing irritation in the groin area during intense activity.
Implementation Method 1
the opening of the 3D textile is stretched and compressed by a walking movement of the wearer thereby creating air movement
Implementation Method 2
At least the left groin portion and the right groin portion may comprise silver on an inner side of the inner layer

AI summary
A lower-body garment comprises a left leg portion, a right leg portion and an intermediate portion connecting the left leg portion to the right leg portion. The intermediate portion has a groin covering portion adapted to extend over a groin area of a wearer. The groin covering portion has a 3D textile. The 3D textile has at least one opening. In use, the opening of the 3D textile is stretched and compressed by a walking movement of the wearer thereby creating air movement.
