Multi-layered Undergarment Gusset System with Stiff-Soft Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional undergarment gusset systems often cause discomfort and embarrassment due to fabric tension revealing body outlines, and separate inserts can lead to friction and waste.
Innovation Solution
A multi-layered undergarment gusset system comprising a first layer, a second layer, a multi-layered gusset insert, and a serged portion, where the gusset insert is permanently coupled via stitching and resistant to bending, preventing movement and friction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a separate insert is used in existing clothing, then the body outline can be concealed, but friction and movement occur causing discomfort
Solution Approach 1:
The gusset insert is merged with the undergarment fabric through permanent coupling via stitching, creating a single integrated unit. This eliminates the separate insert that causes friction and movement, while maintaining the body-concealing function. The gusset is no longer a detachable component but becomes an integral part of the undergarment structure.
Solution Approach 2:
The gusset insert is pre-positioned and permanently stitched to the undergarment fabric during manufacturing. This preliminary action ensures that the gusset remains in the correct position and maintains proper tension relationships with the fabric, preventing movement and friction during wear while concealing the body outline.
2Object-affected harmful factors
If fabric tension is applied to conceal body outline, then embarrassment is reduced, but discomfort increases
Solution Approach 1:
The gusset insert is designed with specific local properties including appropriate thickness, rigidity, and fabric composition that differ from the surrounding undergarment fabric. This local quality allows the gusset to provide body concealment through controlled tension while maintaining comfort through its specific material characteristics and structural properties.
3Object-affected harmful factors
If a separate insert is used, then body concealment is achieved, but material waste increases due to non-reusability
Solution Approach 1:
By merging the gusset insert with the undergarment fabric through permanent coupling, the system creates a single reusable unit. The integrated design eliminates the need for separate inserts that are discarded after use, thereby reducing material waste while maintaining the body-concealing function throughout the undergarment's service life.

AI summary
A multi-layered undergarment gusset system includes a first layer forming an inner surface, a second layer forming an outer surface, a multi-layered gusset insert disposed between the first and second layers, and a serged portion. The multi-layered gusset insert has a first and second material, where the first material includes a stiff, impermeable, synthetic leather fabric resistant to bending, and the second material includes a soft, breathable, three-dimensional mesh spacer fabric. The first material's perimeter is smaller than a corresponding perimeter of the second material, and the first material is fixed in a central position to an outer surface of the second material via stitching. The serged portion of the second layer extends from the second layer and is secured over a first and second side of the first layer to enclose the multi-layered gusset insert between the first and second layers, and keep it in a fixed position.
