Folded-Wing Bra Wing 2-Ply Bonding for Seamless Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bra seams cause discomfort and aesthetic issues due to their bulk and friction against the skin, despite providing necessary support and stretch capability.
Innovation Solution
A bra wing design featuring a 2-ply structure created by folding and bonding a base material with a laminate film adhesive, eliminating seams along high-friction areas while maintaining structural integrity and stretch ability through a fold edge and overhangs for hemming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional seams are used to join and shape bra wings, then functional support and structural integrity are maintained, but comfort deteriorates due to bulk and friction against the skin
Solution Approach 1:
The invention extracts and eliminates the traditional seam structure from the bra wing design. Instead of joining separate fabric pieces with seams, the design uses a single continuous piece of fabric that is folded and bonded, removing the source of bulk and friction while maintaining the necessary structural support through alternative construction methods
Solution Approach 2:
The invention introduces bonding material as an intermediary substance to join fabric layers. This bonding material serves as a mediator that provides structural integrity and support without creating the bulk and friction problems associated with traditional seams, effectively replacing the seam's functional role without its harmful effects
2Stability of the object's composition
If traditional seams are used to maintain wing shape and disperse support force, then structural integrity is improved, but aesthetic appeal deteriorates due to visible bulk through garment layers
Solution Approach 1:
The invention removes the visible seam structure from the bra wing, extracting the aesthetic problem while preserving the necessary structural function through folding and bonding techniques that create a smooth, seamless appearance visible through outer garment layers
Solution Approach 2:
The invention uses thin bonding material films to join fabric layers, creating a structure that is invisible or minimally visible through outer garments. The bonding film provides structural integrity without the bulk of traditional seams, maintaining both shape stability and aesthetic appeal
3Adaptability or versatility
If seams with elastic material are used to provide stretch capability, then adaptability is improved, but comfort deteriorates due to high friction points against skin
Solution Approach 1:
The invention applies elastic properties locally through bonding material with stretch and recovery characteristics in specific areas where adaptability is needed, rather than using elastic seams throughout. This localized approach provides necessary stretch capability while avoiding high-friction elastic seams against the skin in other areas
Solution Approach 2:
The bonding material serves as an intermediary that provides stretch capability without the high friction of elastic seams. This mediator material allows the fabric to expand and contract adaptively while maintaining a smooth surface that reduces friction against the skin
Applied Scientific Principles
