Dual Bra Band Design for Support Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bras often fail to provide adequate support and comfort for larger women, as the weight of the breasts causes shoulder straps to shift, leading to discomfort and undesirable bulging under the arm, which can be visible through clothing.
Innovation Solution
The design incorporates an inner bra band and an outer bra band, with the inner band originating closer to the body and extending upward and outward to provide additional lift and support, while the outer band hugs the sides of the rib cage and attaches to the spine, reducing bulging and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single bra band is used in conventional bras, then the structure is simple, but the bra fails to provide adequate support and allows shoulder straps to shift for larger women
Solution Approach 1:
The single bra band is divided into two separate bands: an inner bra band and an outer bra band. The inner band provides primary support closer to the body, while the outer band provides additional support and stability. This segmentation allows each band to perform its specific function, preventing shoulder strap shifting and improving overall support reliability without creating an overly complex structure.
2Reliability
If the bra band applies pressure to support breasts, then support is improved, but flesh and fat are displaced and bulge out from under the arm
Solution Approach 1:
The pressure application is segmented between two bands positioned at different locations. The inner band applies pressure closer to the body center where it provides support without causing bulging, while the outer band is positioned to provide additional support without displacing flesh and fat under the arm. This spatial segmentation eliminates the harmful bulging effect while maintaining support effectiveness.
Solution Approach 2:
Different regions of the bra structure are given different functions: the inner band is optimized for providing support close to the body, while the outer band is positioned and designed to prevent flesh displacement under the arm. Each band has localized properties tailored to its specific function, resolving the contradiction between support and comfort.
3Reliability
If shoulder straps are positioned to provide support, then breast support is improved, but the weight of breasts causes straps to move forward and pull the bra band up
Solution Approach 1:
The support function is segmented between the shoulder straps and the dual bra bands. The shoulder straps provide primary support for the breast weight, while the two bra bands work together to anchor this support. The inner band prevents the bra from sliding down, and the outer band prevents the bra band from being pulled upward, thereby stabilizing the overall bra position while maintaining the support function.
Solution Approach 2:
The dual bra band system acts as an intermediary between the shoulder straps and the body. The inner band serves as a first intermediary closer to the body, while the outer band serves as a second intermediary that distributes and stabilizes the forces. This intermediary system prevents direct transmission of strap weight to the bra band edges, eliminating the pulling-up effect while maintaining support.
