Adjustable Athletic Bra with Independent Strap Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional athletic bra designs fail to provide adequate three-dimensional support and comfort during athletic activities, as they do not effectively stabilize breasts in multiple directions and often lack adjustability to accommodate varying breast shapes and sizes.
Innovation Solution
An adjustable athletic bra design featuring interconnected elements, including elastomeric and non-elastomeric materials, with independent shoulder straps and back strap systems, and a front support system that allows for customizable tension across the front portion, providing comprehensive lateral, vertical, and in-and-out stabilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional athletic bra designs use hook and eye closure systems or pre-sized pullover designs, then the bra can be easily manufactured and put on, but the bra does not provide adequate three-dimensional support to prevent substantial movement of breasts in multiple directions during exercise
Solution Approach 1:
The bra is divided into multiple independent strap systems (first back strap system and second back strap system) that can be adjusted independently, allowing each strap to provide targeted support in specific directions while maintaining overall structural integrity and breathability
Solution Approach 2:
The bra incorporates adjustable strap systems with multiple attachment points and length variations, enabling dynamic customization of fit and support levels based on individual body shapes, breast sizes, and activity intensities, transforming a static garment into an adaptable support system
2Adaptability or versatility
If conventional athletic bras use molded cups or pre-sized designs, then the bra can be easily manufactured, but the bra does not allow for proper fit as breast shapes and sizes range widely
Solution Approach 1:
Different portions of the bra are constructed with different material properties and structural characteristics - the cups use specific fabrics for comfort and shape, while the straps and band use elastic materials for adjustability and support, allowing each region to be optimized for its specific function while maintaining overall manufacturability
Solution Approach 2:
The bra design uses universal adjustment mechanisms (multiple strap attachment points, adjustable lengths) that can accommodate a wide range of breast shapes and sizes without requiring multiple different bra models, making the single design universally applicable to diverse users
3Reliability
If conventional athletic bras use compression to support breasts, then the bra can provide support, but the compression is commonly uncomfortable
Solution Approach 1:
The support function is segmented across multiple independent strap systems rather than relying on uniform compression, allowing support to be distributed and adjusted in specific areas where it is most needed while leaving other areas more comfortable and breathable
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 bra effectively minimizes three-dimensional breast movement across eight directions, ensuring stability and comfort by allowing for dynamic adjustment to fit individual preferences and activities, addressing asymmetry and providing full support.
Implementation Method 1
The first shoulder strap can be comprised of two pieces of material that are connected to each other with one piece of material including elastomeric properties and the other piece of material including non-elastomeric properties
