Adjustable Sports Bra with Hook and Loop Straps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sports bras lack flexibility to accommodate varying breast sizes and levels of physical activity, leading to breast discomfort during demanding activities.
Innovation Solution
The bra features individually adjustable back and shoulder straps with hook and loop technology and ringed hardware, allowing for unlimited tightening and loosening, providing maximum comfort and support by using hook and loop technology and ringed hardware at the breast cups and back strap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional bras with fixed straps are used, then the structure is simple, but the adaptability to different breast sizes and activity levels is poor
Solution Approach 1:
The bra straps are designed to be dynamically adjustable rather than fixed. The back strap can be adjusted in length, and the shoulder straps can be repositioned on the cups, allowing the bra to adapt to different body sizes and activity levels. This dynamic adjustment capability directly resolves the contradiction by providing versatility without requiring multiple different bra designs.
Solution Approach 2:
The bra is segmented into independently adjustable components: the back strap length is adjustable separately from the shoulder strap positions, which themselves can be moved independently on each cup. This segmentation allows fine-tuned adaptation to individual needs while maintaining a relatively simple overall structure.
2Ease of operation
If straps are made adjustable to fit different sizes, then the comfort and support are improved, but the ease of operation becomes more complex
Solution Approach 1:
The adjustment mechanisms are designed to be simple and dynamic rather than complex and static. The back strap uses a simple length adjustment mechanism, and the shoulder straps can be easily repositioned on the cups without complex fastening systems. This makes the bra easy to operate and adjust for comfort while avoiding unnecessary complexity.
3Reliability
If hardware is added to the apex of cups for strap attachment, then the support for breast during physical activity is improved, but the device complexity increases
Solution Approach 1:
The hardware attachment system is segmented into discrete components: hardware pieces are placed at specific locations on the cups (apex and lower portion), allowing the shoulder straps to be attached at different positions. This segmentation provides reliable breast support during physical activity while keeping each individual hardware attachment point simple and manageable.
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
Enables women to achieve the desired level of compression, support, and comfortable fit, addressing breast discomfort during physical activities by allowing precise adjustment of the bra to suit individual needs.
Implementation Method 1
Hook and loop technology, commercially available under the trademark VELCRO, is the preferred means of connecting and/or tightening the free ends of the three straps.
