Adjustable Brassiere Cups With Pneumatic Volume And Position Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brassieres have fixed cup sizes, which fail to meet the diverse needs of women, such as adjusting cup size for different activities or preferences for tighter or looser fit.
Innovation Solution
A brassiere with adjustable cup members and devices that allow changing volume and position, using gas-filled chambers and rotating adjustment wheels to modify the size and position of the cups, along with rubber strips for enhanced fit and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed-size cups are used in brassiere, then manufacturing is simple and structure is stable, but adaptability to different user needs is poor
Solution Approach 1:
The brassiere incorporates adjustable cups with movable adjustment members that can change position and volume dynamically. The adjustment members are connected to adjustment devices that allow real-time modification of cup characteristics, transforming a static structure into a dynamic one that adapts to different user needs.
Solution Approach 2:
The cup structure is divided into multiple components including cup pads and adjustment members. The adjustment members are further segmented into multiple units that can be independently positioned and adjusted, allowing flexible customization of cup volume and shape without requiring complete redesign of the entire cup structure.
2Adaptability or versatility
If adjustable components are added to change cup size and position, then adaptability improves, but device complexity increases
Solution Approach 1:
The adjustment devices are designed to perform multiple functions: adjusting cup volume, changing cup position, and modifying overall brassiere fit. This multi-functionality reduces the need for separate adjustment mechanisms for each parameter, thereby limiting the increase in device complexity while achieving comprehensive adaptability.
Solution Approach 2:
The adjustment members are nested within the cup pads, and the adjustment devices are integrated into the brassiere structure. This nesting arrangement allows multiple adjustment components to occupy the same space, reducing the overall volume and complexity of the adjustable system while maintaining full functionality.
3Adaptability or versatility
If gas-filled chambers are used for volume adjustment, then adaptability improves, but weight increases
Solution Approach 1:
The adjustment members utilize gas-filled chambers that can be inflated or deflated to change volume. Gas is significantly lighter than solid or liquid alternatives, providing effective volume adjustment capability while minimizing weight increase. The gas chambers allow large volume changes with minimal added mass compared to traditional solid adjustment mechanisms.
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 brassiere provides customizable fit and comfort by allowing adjustment to meet various user needs, improving practicality and aesthetics while reducing weight and shifting.
Implementation Method 1
the gas-filling device is used for filling gas into the gas chamber and releasing the gas from the gas chamber, so as to change the volume of the adjustment member
Implementation Method 2
the connecting structure is capable of shortening or lengthening its own length by winding around or disengaging from the rotating shaft to drive the adjustment member to move when the adjustment wheel is rotated
Implementation Method 3
along with rubber strips for enhanced fit and comfort

AI summary
A brassiere includes a front piece and a back piece bonded to the front piece, with two cup pads fixed at positions of cups between the front piece and the back piece, wherein an adjustment member and an adjustment device connected to the adjustment member are further provided within the cups, the adjustment member being provided so as to be able to change its own volume and/or position under the control of the adjustment device. The brassiere improves the practicality of the brassiere by changing sizes and positions of the cups.
