Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current body-shaping garments, such as brassieres, often face challenges in providing both comfort and adequate support while maintaining three-dimensional shaping ability and minimizing slippage during wearer movement, due to limitations in stretchable materials that are either too constrictive or lack sufficient multi-directional elasticity.
Innovation Solution
A multi-layer fabric construction for body-shaping garments, featuring an inner and outer fabric layer with specific isotropic hysteresis properties and angular orientations, providing a combination of comfort, shaping, and support by ensuring minimal slippage and maintaining contact with the body during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If constrictive materials are used to provide breast support, then support capability is improved, but wearer comfort deteriorates due to irritation and discomfort
Solution Approach 1:
The patent changes the material parameters from constrictive non-stretchable materials to elastomeric stretchable materials with specific elasticity properties. The fabric is constructed with elastomeric yarns in both warp and weft directions, providing multi-directional stretch capability while maintaining support through engineered elasticity rather than constriction.
Solution Approach 2:
The patent uses composite fabric construction combining elastomeric yarns with other fibers in a knit structure. The composite material integrates stretchable elastomeric components with supportive fabric structure, achieving both comfort through elasticity and support through the engineered fabric architecture without requiring constrictive elements.
2Object-affected harmful factors
If stretchable materials are used to improve wearer comfort, then comfort is improved, but breast support capability deteriorates due to insufficient elasticity
Solution Approach 1:
The patent optimizes the elasticity parameters of the stretchable material by incorporating elastomeric yarns with specific stretch properties in both warp and weft directions. The fabric is engineered to provide controlled multi-directional elasticity that offers both comfort through stretch and support through recovered elasticity, rather than using non-stretchable constrictive materials.
Solution Approach 2:
The patent employs composite fabric construction that combines elastomeric yarns with other fibers in a knit structure. This composite material provides the necessary elasticity for comfort while the engineered fabric architecture maintains breast support capability through the integrated stretch and recovery properties of the elastomeric components.
3Object-affected harmful factors
If garment materials are designed for maximum comfort, then comfort is improved, but three-dimensional shaping ability deteriorates
Solution Approach 1:
The patent engineers the fabric with specific elasticity parameters that balance comfort and shaping. The elastomeric yarns are configured with controlled stretch properties that allow comfort through movement while maintaining the ability to hold and shape three-dimensional form through engineered recovery and structured knit patterns.
Solution Approach 2:
The patent uses composite fabric construction combining elastomeric yarns with other fibers in a knit structure that provides both comfort and shaping. The composite material integrates stretchable components for comfort with structured fabric architecture that maintains three-dimensional shaping ability through the engineered interaction of different fiber types and knit patterns.
4Ease of manufacture
If conventional fabric layers are used, then manufacturing is simplified, but garment slippage increases during movement
Solution Approach 1:
The patent changes the fabric material parameters to include elastomeric yarns with specific elasticity properties in both warp and weft directions. This multi-directional stretch capability allows the garment to move with the body while maintaining contact through engineered recovery, preventing slippage without complex construction.
Solution Approach 2:
The patent employs composite fabric construction that combines elastomeric yarns with other fibers in a knit structure. This composite material provides the necessary elasticity for movement comfort while the engineered fabric architecture maintains garment position stability through integrated stretch and recovery properties that prevent slippage during body movement.
