Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless bra cups lack sufficient structural support, leading to breast sagging and wrinkles at the lower edges, compromising both aesthetics and comfort.
Innovation Solution
A size-free brassiere design featuring integrally formed underband and bra cups made of stretchable, shape-retaining material, with an extension fabric extending beyond the lining for personalized customization and enhanced support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless bra cups are designed with simple fabric extension, then comfort and stretchability are improved, but structural support deteriorates leading to breast sagging and wrinkles
Solution Approach 1:
The bra cup is divided into multiple fabric layers including a first fabric layer, second fabric layer, third fabric layer, and fourth fabric layer. Each layer serves specific functions: the first and second layers provide stretchability and comfort, while the third and fourth layers provide structural support and shape retention. This segmentation allows the bra to simultaneously achieve comfort and structural support.
Solution Approach 2:
The bra cup employs a composite structure combining different fabric types with distinct properties. The stretchable fabric layers are combined with shape-retaining fabric layers to create a multi-functional material system that delivers both comfort (through stretchability) and structural support (through shape retention), resolving the contradiction between these two requirements.
2Strength
If conventional bra cups use steel or plastic underwires for support, then structural support is improved, but comfort and natural fit deteriorate
Solution Approach 1:
The invention removes the traditional steel or plastic underwire components from the bra cup design. Instead of using rigid support elements, the patent employs a wireless design where structural support is achieved through the multi-layer fabric construction itself, particularly the shape-retaining layers that provide necessary support without compromising comfort or natural fit.
Solution Approach 2:
The patent replaces rigid underwire structures with flexible fabric layers that have shape-retaining properties. These flexible fabric layers conform to the body's natural contours while providing the necessary structural support, eliminating the discomfort and artificial feel associated with rigid underwires.
3Ease of operation
If wireless bra cups lack sufficient support structure, then comfort is improved, but breast sagging and wrinkles at lower edges occur
Solution Approach 1:
The bra cup is segmented into multiple functional layers where the third and fourth fabric layers are specifically designed with shape-retaining properties. These layers are positioned to provide targeted support at critical areas, preventing breast sagging and wrinkles while maintaining overall comfort through the stretchable first and second layers.
Solution Approach 2:
Different regions of the bra cup have different fabric layer configurations tailored to local support requirements. The shape-retaining layers are strategically positioned to provide enhanced support where needed (at the lower edges and breast tissue areas) while allowing stretchability in other regions, achieving both comfort and positional stability.

AI summary
A size-free brassiere providing under-bust support comprises an underband and two bra cups, and the two bra cups are arranged side by side on the same side of the underband. The underband is fixedly connected to the two bra cups; the underband and the bra cups are both made of a stretchable, shape-retaining material, and the underband and the two bra cups are integrally formed. The present disclosure not only provides stretchability to ensure wearer comfort, but also addresses the problem in existing market styles, which often cause breast sagging and the formation of wrinkles and folds at the lower edge of the bust due to insufficient support, thereby enhancing breast support and presenting an uplifted contour.
