Bra Support Structure Using Discrete Cable Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bras are time-consuming and expensive to manufacture and provide limited customizability and support, relying on varying textile materials and molding to create a "cup" shape for breast support.
Innovation Solution
A support structure for bras featuring discrete cable structures made of low- or no-stretch materials that extend vertically from the upper to the lower aspect of the breast-covering portion, transitioning from a zig-zag to a linear configuration when tensioned, providing customized support by adjusting geometry for different breast sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional textile panels with varying stretch and molded materials are used to provide breast support, then support and fit are achieved, but manufacturing becomes time-consuming and expensive
Solution Approach 1:
The support structure is divided into multiple discrete cable structures instead of using continuous textile panels. Each cable structure is an independent element that can be separately manufactured and then assembled, replacing the traditional molded cup construction with segmented components that are easier and faster to produce.
Solution Approach 2:
The invention changes the fundamental parameter of support structure from stretch-based textile panels to tension-based cable elements. By using low-stretch materials configured in zig-zag patterns that transition to linear configurations under tension, the support mechanism fundamentally changes how force is applied, enabling simpler manufacturing while maintaining or improving support effectiveness.
2Strength
If traditional molded textile materials are used to create cup shape, then breast support is provided, but customizability of fit and support is limited
Solution Approach 1:
The cable structures are designed to dynamically change configuration from zig-zag in the un-tensioned state to linear in the tensioned state. This dynamic behavior allows the same structure to adapt to different breast sizes and shapes, providing customizable fit without requiring multiple pre-molded options. The cables naturally adjust their tension and configuration based on the wearer's anatomy.
3Ease of manufacture
If discrete cable structures with zig-zag configuration are used, then manufacturing is simplified and customizability is improved, but support effectiveness must be maintained
Solution Approach 1:
The cable structures utilize geometric curvature through zig-zag configurations that convert to linear forms under tension. This geometric transformation ensures that the cables provide optimal support effectiveness when tensioned, while maintaining manufacturing simplicity in the un-tensioned state. The curved zig-zag pattern is easier to manufacture than perfectly straight cables, yet transforms into an effective linear support structure when needed.
