Innovation Solution
A detachable link for watch bands comprising an I-piece with recesses and spring bars, allowing quick connection and disconnection without tools, using a key to release the connection between links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external tools are used to adjust watch band length, then the connection between links can be securely maintained, but the operation becomes inconvenient and requires professional assistance
Solution Approach 1:
The watch band link incorporates a self-service adjustment mechanism where users can directly press the exposed end of the spring bar to release the connection, eliminating the need for external tools. The spring bar is designed to be accessible from the outside, allowing users to perform adjustments themselves without requiring professional assistance.
Solution Approach 2:
The spring bar acts as an intermediary element between the link body and the adjacent link. It provides a mechanical interface that can be easily actuated by users while maintaining secure connection when engaged, and can be released by simple pressure on its exposed end.
2Measurement precision
If external tools are used for watch band adjustment, then precise control over connection release is achieved, but the risk of damage to watch band or connecting pin increases
Solution Approach 1:
The design allows users to directly manipulate the spring bar without external tools, eliminating the risk of tool-induced damage to the watch band or connecting pins. The spring bar's exposed end is specifically designed to be pressable by fingers, providing a safe and tool-free adjustment method.
Solution Approach 2:
The spring bar is designed as a sacrificial or replaceable component that can be easily replaced if damaged, protecting the more valuable watch band and connecting pins from damage. This approach prioritizes the protection of critical components.
3Strength
If traditional watch band design is used, then structural integrity is maintained, but rapid disassembly and length adjustment cannot be achieved without special tools
Solution Approach 1:
The watch band link is segmented into distinct functional components: the link body, the spring bar, and the recesses. This segmentation allows the spring bar to be independently actuated for rapid release while the link body maintains its structural integrity. The detachable nature of the spring bar enables quick adjustment without compromising the overall strength of the watch band.
Solution Approach 2:
The spring bar provides dynamic functionality to an otherwise static link structure. It can be in a locked state maintaining strong connection, or easily transitioned to an unlocked state for rapid disassembly. This dynamic element enables the watch band to switch between secure connection and easy adjustment modes.
