Crossing Strap Sport Bra with Elastic Cup Band
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bras, including support and sport bras, often compress breasts and limit movement, leading to discomfort and pain such as headaches, backaches, and neck and shoulder pain, as they fail to utilize natural gravity and leverage for balanced support.
Innovation Solution
The design incorporates adjustable shoulder straps with hook and loop fasteners, a horizontal, elastic breast cup band with a buckle, and crossing shoulder straps to provide comfortable and balanced breast support, allowing for quick adjustments and improved movement freedom.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bras compress breasts against the chest to limit movement, then breast support is provided, but discomfort and pain occur
Solution Approach 1:
Instead of compressing breasts upward against the chest wall, the bra inverts the support approach by allowing natural downward movement while providing support through the band and back structure. The straps are designed to distribute weight rather than compress, and the cup structure supports from below rather than compressing from above and around.
Solution Approach 2:
The invention converts the harmful compression force into beneficial support by using the natural downward force of gravity as the primary support mechanism. The bra structure is designed to work with gravity rather than against it, allowing breasts to move naturally downward while the band and straps provide balanced counter-support, eliminating the need for harmful compressive forces.
2Stability of the object's composition
If bras limit breast movement for support, then breast stability is improved, but freedom of movement is reduced
Solution Approach 1:
The bra inverts the traditional approach by not restricting natural downward movement caused by gravity. Instead of limiting movement through compression, the design allows free downward movement while providing support through the band and back structure, achieving stability without restricting freedom of movement.
Solution Approach 2:
The bra employs dynamic design elements including elastic materials and adjustable straps that adapt to movement rather than restricting it. The structure allows natural breast movement while maintaining support through flexible, responsive components that move with the wearer rather than constraining movement.
3Reliability
If shoulder straps are tight to provide support, then breast support is improved, but straps dig into shoulders causing pain
Solution Approach 1:
The bra employs asymmetric strap design where the straps are positioned and angled to distribute weight across the shoulder and back rather than concentrating force on the shoulder point. The crossing strap configuration creates asymmetric force distribution that reduces pressure points while maintaining support effectiveness.
Solution Approach 2:
Instead of relying on tight shoulder straps for support, the invention inverts the support approach by using the band and back structure as the primary support mechanism. The straps are designed to guide and distribute force rather than provide the main support, eliminating the need for tight straps that dig into shoulders.
4Reliability
If bras use compression to reduce movement, then breast support is provided, but headaches and backaches occur
Solution Approach 1:
The invention converts the harmful compressive forces into beneficial support by using gravity as the primary support mechanism. The bra structure is designed to work with the natural downward force of gravity, allowing breasts to move naturally while the band and straps provide balanced counter-support, eliminating the need for harmful compressive forces that cause headaches and backaches.
Solution Approach 2:
The bra inverts the traditional support approach by not resisting natural downward movement through compression. Instead, it provides support through the band and back structure while allowing free downward movement, working with gravity rather than against it to eliminate harmful compressive forces.
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
The solution enhances comfort and reduces pain by allowing for customizable fit, balanced breast support, and increased freedom of movement, preventing straps from digging into the shoulders and providing effective relief from related discomforts.
Implementation Method 1
The shoulder straps can be opened and closed using a shoulder strap buckle mounted on one end of the shoulder straps with hook and loop fasteners mounted on an opposite end of the shoulder straps
Implementation Method 2
a horizontal, elastic, breast cup band with a buckle

AI summary
A breast sport bra and a breast support bra for providing a women wearer with a comfortable breast support, a balance of the breasts, and freedom of movement, the breast support bra includes a first breast cup and a second breast cup. The breast cups are attached to a top portion of horizontal, elastic, breast cup band. The breast cup band is releasably attached the first and second breast cups for separating the cup one from another. A first shoulder strap is attached to a top portion of the first breast cup and an opposite end of the first shoulder strap is attached to a side of the second breast cup and an end portion of the breast cup band. A second shoulder strap is attached to a top portion of the second breast cup and an opposite end of the second shoulder strap crossing the first shoulder strap in an “X” configuration and attached to a side of the first breast cup and an end portion of the breast cup band.
