Adjustable Bra Strap and Band Mechanism for Fit Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bras often fail to fit various body shapes within a single cup size due to their fixed sizing, leading to discomfort and inefficiency, as they are typically designed based on circumferential measurements and breast size without accommodating individual body variations.
Innovation Solution
The bra incorporates adjustable shoulder straps with a 'G' hook and multiple pocket-like loop structures, allowing for length adjustment and elastic segments in the body surround for maximum sizing flexibility, along with comfort closures to secure the adjustment mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a bra is designed with fixed sizing based on circumferential measurements and cup size, then the manufacturing and sizing process is simplified, but the garment cannot accommodate various body shapes within the same cup size, leading to poor fit and discomfort
Solution Approach 1:
The bra is divided into multiple adjustable components: the band with multiple closure positions (at least three different lengths), the cups with adjustable straps, and the straps with independent length adjustment. This segmentation allows each component to be adjusted independently to accommodate various body shapes while maintaining a standardized base design.
Solution Approach 2:
The bra incorporates dynamic adjustment mechanisms that allow the wearer to change the fit after manufacturing. The band closure can be positioned at multiple locations along the band, and the shoulder straps can be adjusted to different lengths, enabling the same bra to adapt to different body sizes and shapes without requiring multiple fixed-size models.
2Adaptability or versatility
If multiple closure positions are provided on the band to adjust length, then adaptability to different body sizes is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The band is designed with segmented adjustment points where closure elements can be positioned at multiple predetermined locations. This segmentation allows the band to be manufactured as a single piece with built-in adjustment capability, rather than requiring multiple different band lengths to be produced and inventoried.
Solution Approach 2:
The band closure system serves multiple functions: it provides the primary closure of the bra, allows adjustment of band length to accommodate different body sizes, and maintains structural support. By integrating these functions into a single adjustable mechanism, the design avoids the need for separate adjustment devices that would complicate manufacturing.
3Adaptability or versatility
If adjustable straps with multiple length positions are added to the bra, then the ability to accommodate different body shapes is improved, but the device complexity and number of components increase
Solution Approach 1:
The shoulder straps are designed with dynamic adjustment capability, allowing the length to be changed by the wearer. Each strap can be adjusted independently to the appropriate length for the wearer's shoulder width and preference, providing adaptability without requiring multiple complete bra designs.

AI summary
The bra adjustment mechanism enables a wearer to modify the fit of the garment. The adjustment mechanism is suitable for bras having a cup portion, a body surround portion and a strap that is connected between the cup and body surround portions. The strap has a free end with a connector for attaching the strap to a body surround portion, which has a plurality of connection positions for to securing the connector to the body surround at a selected position. The body surround preferably includes an elastic segment that provides an expansion area in the body surround for maximum sizing flexibility upon closure of the bra or movement by a wearer.
