Undergarment Panel Design Redistributes Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Female undergarments, such as briefs, often create pressure points around the leg and center front due to design and fabric components, leading to discomfort and tension.
Innovation Solution
A female undergarment design featuring a second fabric layer secured to the first fabric layer at the crotch and abdominal regions, with a wider abdominal seam distributing vertical pull across the crotch region, reducing tension at the leg openings through a trapezoid or chevron-shaped mesh fabric configuration and continuous seams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional undergarment design with standard fabric layers and closure panels is used, then the garment provides basic coverage and support, but it creates pressure points around the leg and center front regions leading to discomfort
Solution Approach 1:
The garment is divided into multiple fabric layers (first and second fabric layers) with distinct functional zones. The second fabric layer is selectively positioned and secured at specific regions (crotch and abdominal regions) to target tension redistribution without adding complexity throughout the entire garment structure.
Solution Approach 2:
The second fabric layer is designed with varying width characteristics - wider at the abdominal region and narrower at the crotch region - to provide localized tension redistribution where needed most. This non-uniform distribution of material properties addresses pressure points specifically at the leg openings and center front without over-engineering the entire garment.
2Object-affected harmful factors
If the second fabric layer is made wider at the abdominal region to distribute vertical pull, then tension at the leg openings is reduced, but the device complexity increases
Solution Approach 1:
The second fabric layer incorporates elastic or stretchable material properties that allow it to dynamically adapt to the wearer's body movements and tension forces. This dynamic characteristic enables the layer to automatically redistribute tension forces without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The width parameter of the second fabric layer is deliberately varied across different regions (wider at abdomen, narrower at crotch) to optimize tension distribution. This parameter modification allows a single continuous layer to perform multiple functional roles without requiring multiple separate components.

AI summary
A female undergarment (100) including a first fabric layer (102) having an abdominal region (106) and a crotch region (108) and a second fabric layer (104) secured to the first fabric layer (102) at the crotch region (108) and at the abdominal region (106). The crotch region (108) is defined by first and second leg openings (110). The second fabric layer (104), secured to the first fabric layer (102) at the crotch region (108) and at the abdominal region (106), defines a first opening (118) between the first fabric layer (102) and the second fabric layer (104) proximate the first leg opening (110) and a second opening (118) between the first fabric layer (102) and the second fabric layer (104) proximate the second leg opening (110). Manufacturing the undergarment (100) includes forming a first fabric layer (102) (having an abdominal region (106) and a crotch region (108), and securing a second fabric layer (104) to the first fabric layer (102) at the crotch region (108) and at the abdominal region (106), thereby defining the first opening (118) and the second opening (118).
