Removable Underwire Attachment for Brassiere Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Underwire bras can be uncomfortable due to constrictive pressure, skin irritation, and the risk of metal exposure, and the underwire is difficult to remove without damaging the bra.
Innovation Solution
A U-shaped underwire attachment that is externally inserted and removable, providing support and shape without being sewn into the fabric, allowing for easy insertion and removal along the bottom of the bra cups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the underwire is stitched into the fabric of the bra, then the structural integrity and support are improved, but the ease of removal and adaptability deteriorate
Solution Approach 1:
The underwire assembly is divided into separate components: the underwire itself and the attachment mechanism. This segmentation allows the underwire to be removed and reattached without damaging the bra fabric, resolving the contradiction between maintaining structural integrity and enabling easy removal.
Solution Approach 2:
The attachment mechanism transforms the static, permanent underwire installation into a dynamic, reversible connection. The snap fastener or hook-and-loop fastener allows the underwire to be easily attached and detached, providing adaptability while maintaining support when needed.
2Strength
If the underwire is made rigid to provide support and shape, then the structural support is improved, but the comfort and adaptability deteriorate due to constrictive pressure
Solution Approach 1:
The bra design incorporates different levels of support in different areas. The underwire provides rigid support only where structurally necessary at the bottom of the cup, while the sides and other areas use softer, more flexible materials that conform to the body and reduce skin irritation.
Solution Approach 2:
The removable underwire allows the wearer to dynamically adjust the level of support based on comfort needs. When the rigid underwire causes discomfort, it can be removed, allowing the bra to become more flexible and adaptable to the wearer's body contours.
3Reliability
If the underwire is permanently attached to provide consistent support, then the reliability is improved, but the adaptability and versatility deteriorate
Solution Approach 1:
The attachment mechanism enables the underwire to be reliably attached when needed for support, yet easily removed when adaptability is desired. This dynamic attachment system provides both consistent support during wear and flexibility for storage, washing, or configuration changes.
Solution Approach 2:
The removable underwire can be detached from the bra for separate storage and maintenance. This allows the underwire to be recovered and reused in different bras or configurations, enhancing versatility while maintaining reliable support when reattached.
4Shape
If the underwire is exposed to provide shaping, then the structural function is improved, but the safety deteriorates due to risk of skin contact with metal
Solution Approach 1:
The attachment mechanism acts as an intermediary between the metal underwire and the bra fabric. This intermediate layer ensures that the underwire remains positioned correctly for shaping while preventing direct exposure of metal edges that could cause skin contact and dermatitis.

AI summary
A removable underwire attachment that is externally inserted over a cup of a brassiere is provided. The underwire attachment may include a U-shape wire that includes a first curved portion configured with a first end seamlessly coupled to a second curved portion configured with a second end. The first end and the second end may be inserted along a bottom portion of a cup of the brassiere to removably fasten the attachment to the brassiere for additional support and shape.
