Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length back strap is used in traditional bras, then the structure is simple and easy to manufacture, but it cannot adapt to different body sizes and becomes difficult to wear when users gain weight
Solution Approach 1:
The extension strap introduces adjustable length capability through movable hooks that can slide along the strap, transforming the fixed-length back strap into a dynamic, adaptable structure. This allows the bra to accommodate different body sizes and weight changes while maintaining a relatively simple overall structure.
Solution Approach 2:
The back strap system is segmented into multiple components: the original back strap, the extension strap with holding spaces, and movable hooks. This segmentation allows independent adjustment of each component, enabling adaptability to different body sizes without complicating the entire bra structure.
2Adaptability or versatility
If a simple extension strap is added to extend bra length, then the ease of wearing is improved, but it cannot adapt to different bras with different clasp distances
Solution Approach 1:
The extension strap incorporates movable hooks that can slide along the strap length, providing dynamic adjustability. This allows the strap to be customized for different clasp distances between various bra models, significantly improving compatibility while maintaining ease of operation through simple hook movement.
Solution Approach 2:
The extension strap design with multiple holding spaces and movable hooks creates a universal solution that can be attached to different bra models with varying clasp distances. The same extension strap can serve multiple functions across different bra types, improving both adaptability and user experience.
3Adaptability or versatility
If the extension strap uses fixed hook positions, then the structure is simple, but it provides poor adaptability to different clasp distances
Solution Approach 1:
The extension strap is divided into multiple holding spaces with openings, and hooks are segmented as separate movable components. This segmentation allows hooks to be positioned at different locations along the strap, providing adjustability to various clasp distances while keeping each individual component relatively simple in structure.

AI summary
An extension strap for a bra includes a base element, a first clasp element, a second clasp element and a fasten element group. The base element includes a first portion, a second portion and a third portion. The first portion includes a first accommodating space and a first opening. The first clasp element includes a first clasp and a first connection portion, the first connection portion is located in the first accommodating space, and the first clasp protruding from the first opening. The fasten element group includes at least two fasten elements disposed on the second portion, each fasten element includes a ring portion and a base portion connected between the ring portion and the second portion. The first clasp is configured to move along the first opening so as to change a distance between the first clasp element and the second clasp element.
