Open-Back Undergarment with Adhesive Cups and G-Shaped Fastener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bra designs with vertical support elements obstruct the open-back effect of dresses and cause discomfort due to visible straps and material-related issues, while designs without these elements often use stiff or harmful materials, and existing solutions fail to provide a fully open back or are technically complex and unreliable.
Innovation Solution
A ladies undergarment featuring shaping cups with adhesive bases, vertical support elements that fasten using a G-shaped fastener with closed and open portions, allowing for adjustable and detachable support elements that can be positioned to create an entirely open back, reducing visibility and discomfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If vertical support elements (shoulder straps) are used to support the bra, then breast support is maintained, but the open-back effect is obstructed and aesthetic appeal is reduced
Solution Approach 1:
The invention extracts and removes the traditional vertical shoulder straps from the bra structure, replacing them with adhesive shaping cups that attach directly to the breast tissue. This eliminates the visual obstruction of the open-back design while maintaining breast support through direct adhesion rather than external straps.
Solution Approach 2:
The invention introduces adhesive material as an intermediary between the bra cups and the breast tissue, replacing the need for vertical support elements. The adhesive acts as a mediator that provides both attachment and support functions without requiring visible external straps.
2Shape
If transparent shoulder straps are used, then visibility is reduced, but skin breathing is blocked and perspiration increases
Solution Approach 1:
The invention completely removes the shoulder strap element from the design, eliminating both the visibility issue and the harmful effect of blocking skin breathing. By using adhesive cups that attach directly to the breast, there are no external straps contacting the skin at all.
3Shape
If vertical support elements are completely removed, then open-back design is achieved, but breast support becomes insufficient
Solution Approach 1:
The invention replaces the mechanical strap-based support system with an adhesive-based attachment system. The adhesive cups utilize adhesion forces directly at the breast-cup interface, providing support without requiring external mechanical straps or wires.
4Strength
If stiff horizontal support elements (wires, plastics) are used, then structural support is provided, but comfort during prolonged wearing is reduced
Solution Approach 1:
The invention removes traditional horizontal support elements such as wires and rigid plastics from the bra structure. Support is achieved through the adhesive attachment of soft shaping cups, eliminating the need for stiff internal frameworks that cause discomfort.
Solution Approach 2:
The invention uses composite material construction for the shaping cups, combining soft, comfortable materials with adhesive properties. This allows the cups to provide both structural support and comfort without requiring rigid internal components.
