Bra Girth Reducing Extension Piece
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing back band adjustment systems in bras fail to maintain a constant girth during use and do not allow for sufficient reduction in size, especially after weight loss or changes in mass distribution, leading to an imperfect fit.
Innovation Solution
A retrofittable shortening system with a releasable and adjustable connection mechanism and an extension piece of flexible material that connects to existing back band connectors, allowing for the reduction of the bra's circumference by coupling with both the original and additional back bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a slide connection and adjustment mechanism is used on the back band, then the length of the back band can be adjusted, but the back band fails to maintain a constant girth during use as the slide adjustment mechanism is subject to readjustment
Solution Approach 1:
The back band is divided into multiple discrete adjustment positions using separate hooks and eyes instead of a continuous slide mechanism. This segmentation allows the band to be adjusted to specific predetermined lengths while maintaining stability at each position, preventing unintended readjustment during wear.
2Adaptability or versatility
If existing back band coupling systems are used, then the bra provides fixed size options, but the system does not allow for sufficient reduction in size after weight loss or changes in mass distribution
Solution Approach 1:
An extension piece is introduced as an intermediary component between the existing back band hooks/eyes and the bra cups. This extension piece includes additional hooks and eyes that provide extra adjustment positions, enabling further size reduction without modifying the original coupling system design.
Solution Approach 2:
The extension piece is designed to be attached to the existing back band structure, nesting additional functionality within the原有 framework. The extension piece integrates with the existing hooks and eyes system, adding adjustment capability while maintaining compatibility with the original design.
3Length of moving object
If the back band is made shorter to accommodate weight loss, then the fit improves, but the original coupling system cannot provide sufficient shortening
Solution Approach 1:
The adjustment system is made dynamic by adding multiple detachable connection points through the extension piece. This allows the back band circumference to be dynamically adjusted to various lengths depending on the user's needs, providing adaptability for different body changes while achieving the desired shortening.

AI summary
The invention includes a girth reducing device including a connector, an extension affixed to the connector and fasteners affixed to the extension. The connector may connect to a back band of a bra assembly and the fasteners affixed to the extension may connect to another back band of the bra assembly. The connections may be made in a manner that allows for a reduced girth of the bra from a smallest girth possible utilizing existing coupling systems of the bra.
