Adhesive Bra Vertical Support Strap for Large Cup Lift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bra constructions for large breasted women are inadequate for supporting larger breast sizes, such as D, DD, DDD, G, and H cups, especially when wearing plunge and/or backless overgarments, as they lack sufficient adhesion and support.
Innovation Solution
A bra design featuring separate breast support members with a concave cavity and reusable pressure-sensitive adhesive on the rear facing surface, along with an elongate support strap and underwire stiffener for enhanced support, made from stretchable planar material and clear transparent strap for concealment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If separate left and right breast cups with adhesive are used, then smaller breasts (A, B cups) can be adequately supported, but larger breasts (D, DD, DDD, G, H cups) are generally inadequate for support
Solution Approach 1:
The bra is divided into separate functional components: left and right breast cups, vertical support straps, and wing portions. This segmentation allows each component to be optimized independently - the cups provide breast containment while the vertical straps provide additional support leverage for larger breasts, and the wings extend adhesion area for stability.
Solution Approach 2:
The invention adds a vertical dimension to the traditional horizontal cup design by incorporating vertical support straps that extend from the upper periphery of each cup upward toward the shoulder region. This vertical extension creates additional adhesion surface area and support leverage in the vertical direction, which is critical for supporting the greater weight of larger breasts.
2Strength
If adhesive area is increased to support larger breasts, then support capability improves, but visibility and aesthetic appearance may worsen
Solution Approach 1:
The vertical support straps are constructed from transparent or skin-tone material that matches the wearer's skin, making them invisible or minimally visible under overgarments. This local quality change allows the straps to provide necessary support and adhesion area while maintaining aesthetic appearance and remaining concealed under clothing.
3Strength
If vertical support strap is added for larger breast support, then support capability improves, but device complexity increases
Solution Approach 1:
The vertical support strap is integrated with the breast cup and wing portion to form a unified adhesive bra construction. The strap is attached to the upper periphery of the cup and works in conjunction with the wing to create a continuous support structure, eliminating the need for separate strap components and simplifying the overall device.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Provides comfortable and secure support for large breast tissue mass, allowing adjustable breast lift and spacing for optimal comfort and appearance, suitable for various cup sizes and overgarment styles.
Implementation Method 1
The planar material has a rear facing surface, including the surface portions in and around the cavity, that carries a reusable pressure sensitive adhesive for adhering to a user's skin
