Brassiere Cup Side-Wing Attachment with Hidden Thread Lines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brassieres have exposed threaded stitches on the inner side, which are uncomfortable and undesirable for wearers.
Innovation Solution
A brassiere design where the side-wing is attached to the bra cup using at least one thread line on the outer side, with the inner side devoid of thread lines, and includes a stabilizer sandwiched between the side-wing and the flange, and a method of manufacturing that involves folding and adhesive attachment to ensure the thread lines are hidden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If side-wing is attached to bra cup by sewing with threads, then attachment strength is improved, but exposed threaded stitches on inner side cause discomfort
Solution Approach 1:
The patent introduces a multi-layer construction with outer layer, middle layer, and inner layer arranged in different spatial dimensions. The thread line is positioned in the outer layer, while the inner layer remains free of threads, effectively moving the harmful threads to a different dimensional plane away from the wearer's skin.
Solution Approach 2:
The middle layer acts as an intermediary between the outer layer (containing threads) and the inner layer (contacting wearer). This intermediate layer blocks the threads from directly contacting the wearer, eliminating discomfort while preserving attachment strength.
2Ease of manufacture
If conventional sewing method is used to attach side-wing, then manufacturing simplicity is improved, but exposed threads on inner side are undesirable
Solution Approach 1:
The patent positions the thread line in the outer layer of the multi-layer construction, separating it from the inner layer that contacts the wearer. This dimensional arrangement hides threads from the wearer's perspective while maintaining conventional sewing methods for attachment.
3Stability of the object's composition
If multi-layer construction with stabilizer is used, then structural stability is improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functional elements into an integrated multi-layer construction where the outer layer, middle layer, inner layer, and stabilizer work together as a unified structure. This merging approach achieves structural stability while managing complexity through functional integration.
Solution Approach 2:
The brassiere cup is segmented into distinct functional layers: outer layer for attachment, middle layer for stabilization, and inner layer for comfort. This segmentation allows each layer to perform its specific function optimally while contributing to overall structural stability.

AI summary
A brassiere having a side-wing and a bra cup is disclosed. The bra cup has a cup portion and a flange portion attached to the side-wing. The flange portion includes a flange disposed at an inner side of the bra cup, and an outer layer being disposed at an outer side of the bra cup and coupled to the flange. Further, a portion of the side-wing is disposed between the outer layer and the flange, and is attached to the outer layer by using at least one thread line. The at least one thread line is disposed on the outer side of the bra cup. Further, the inner side of the bra cup is devoid of thread line.
