Bra Strap Cover with Mechanical Fastening to Eliminate Adhesive Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bra strap covers require adhesives, which can damage the strap material and leave residue, making them impractical for securing bra straps without damaging clothing or leaving unsightly marks.
Innovation Solution
A bra strap covering device with three or five panels, featuring complementary fastening devices such as snaps, zippers, or elastic materials to securely attach around the bra strap without adhesives, using fabric materials that can stretch to accommodate various strap widths and lengths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used to secure the bra cover to the strap, then the bra cover can be securely attached, but the adhesive may damage the strap material and leave sticky residue
Solution Approach 1:
The patent removes the adhesive component entirely from the system, replacing it with a mechanical fastening mechanism consisting of a cover and a buckle that attaches to the bra strap without requiring any adhesive substances, thereby eliminating the harmful effects of adhesive damage and residue
Solution Approach 2:
The patent introduces a buckle as an intermediary mechanical element that mediates the attachment between the bra cover and the strap, providing secure fastening through mechanical engagement rather than chemical adhesion, thus avoiding the harmful effects of adhesives on the strap material
2Reliability
If adhesive is used to secure the bra cover, then attachment is achieved, but the adhesive wears off over time making the bra cover unusable
Solution Approach 1:
The patent eliminates the adhesive component that degrades over time, replacing it with a mechanical buckle system that provides durable, long-lasting attachment without the wear-off problem inherent in adhesive-based solutions
Solution Approach 2:
The patent employs a durable mechanical buckle system that is designed to last throughout the product's usage life, replacing the temporary adhesive bond that deteriorates over time with a permanent mechanical fastening mechanism
3Ease of manufacture
If a specialty bra is purchased to eliminate visible straps, then the appearance issue is resolved, but the cost and limited fit options reduce practicality
Solution Approach 1:
The patent separates the strap coverage function from the bra itself, creating a standalone cover component that can be attached to any existing bra, thereby maintaining bra versatility and fit options while resolving the appearance issue without requiring specialty bras
Solution Approach 2:
The patent creates a universal strap cover solution that can be attached to any bra style and fits various body types, providing strap concealment functionality without limiting the user to specific bra types or sizes, thus maintaining adaptability and versatility

AI summary
A covering device for attachment around a bra-strap having three panels, wherein the panels are substantially the same length as the strap length and at least as wide as the strap width, and wherein the two side panels having complementary pairs of fastening devices to secure the side panels around the bra-strap, thereby securing the bra-strap between the panels.
