Bra Cup Structure With Localized Filling for Reduced Edge Stiffness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The outer edges of traditional bra cups, which are completely overlapped by fabric and lining, become stiff, affecting breathability and comfort.
Innovation Solution
A bra cup design featuring an outer cover layer with an arc-shaped concave surface and a filling layer arranged on this surface, omitting the lining and reducing the thickness of the outer edge by distributing the filling layer only where support is needed, with optional inner and middle layers for additional support and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the outer edges of fabric and lining are completely overlapped and sutured, then the bra cup structure is stable and complete, but the outer edges become stiff and breathability is reduced
Solution Approach 1:
The patent removes the lining layer from the bra cup structure, extracting the problematic overlapping edge configuration. By eliminating the lining, the patent avoids the stiffness caused by double-layer overlapping while maintaining structural integrity through the filling layer and bonding adhesive alone.
Solution Approach 2:
The patent applies different structural approaches to different regions: the filling layer provides localized support where needed, while the outer cover layer maintains overall structure. The bonding adhesive creates localized strong bonds at critical points without requiring complete edge overlap, allowing breathability in non-critical areas.
2Area of stationary object
If the outer edges of fabric and lining are completely overlapped, then the bra cup has sufficient coverage, but the thickness of the outer edge increases causing stiffness
Solution Approach 1:
The patent removes the lining layer that contributes to edge thickness. By eliminating this redundant layer at the edges, the patent reduces outer edge thickness while maintaining adequate coverage through the outer cover layer and filling layer combination.
Solution Approach 2:
The patent changes the structural parameters of the bra cup by eliminating the lining layer, thereby reducing the thickness parameter at the outer edges. This parameter change directly addresses the stiffness issue caused by excessive thickness while preserving functional coverage.
3Strength
If complete overlap of fabric and lining is used, then the bra cup structure is robust, but breathability is affected
Solution Approach 1:
The patent extracts the lining layer that creates the breathability problem. By removing this layer, air can pass more freely through the bra cup structure while the filling layer and bonding adhesive maintain necessary structural robustness.
Solution Approach 2:
The patent applies structural strength locally where the filling layer and bonding adhesive provide support, rather than requiring complete edge overlap throughout. This localized approach to structural reinforcement maintains robustness where needed while preserving breathability in other areas.

Function Achieved in This Case
Improves breathability and comfort by reducing the stiffness of the outer edge, allowing for a seamless effect and enhanced wearing experience, especially with casual clothing.
Implementation Method 1
the outer cover layer and the middle layer, the middle layer and the filling layer, and the filling layer and the inner cover layer are all bonded with a hot melt adhesive

AI summary
The present disclosure relates to the technical field of underwear. A bra cup and a bra are disclosed. The bra cup has an outer cover layer and a filling layer, where the filling layer is arranged on a side of the outer cover layer located on an arc-shaped concave surface. Compared with bra cups which are laminated by a fabric and a lining, a lining of the bra cup provided by the present disclosure is removed. Since the filling layer is only distributed in parts that need to be supported, the thickness of an outer edge of the cup is reduced to avoid the stiffness of the outer edge, thereby improving the breathability.
