Bracelet Link Assembly Rigid Pin and Socket Welding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing link assembly systems for bracelets made of hard materials suffer from movement between external and central links, resulting in gaps and a compromised aesthetic appearance due to lack of rigidity.
Innovation Solution
A permanent securing device is introduced, where a pin is mounted in a central element's through hole and secured in blind recesses of side elements with locking means, and welded to a socket for enhanced stability, preventing deformation during bending, extension, or twisting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If external links are freely mounted to receive pins from adjacent assembly systems, then assembly is simplified, but the external links can move slightly from their initial position creating gaps that impair aesthetic appearance
Solution Approach 1:
A socket is introduced as an intermediary component between the pin and the external link. The socket is secured inside the blind recess of the external link with locking means, and the pin is welded to the socket. This intermediary structure provides a more rigid connection that prevents movement and gap formation while maintaining assembly feasibility.
Solution Approach 2:
The connection between pin and external link is merged into a permanent securing device through welding. The pin is welded to the socket, creating an integrated permanent connection that eliminates relative movement between components, thereby preventing gap formation and maintaining aesthetic appearance.
2Stability of the object's composition
If a permanent securing device with welding is used to connect assembly systems, then rigidity and aesthetic appearance are improved, but device complexity increases
Solution Approach 1:
The permanent securing device is segmented into distinct functional components: a pin for connection, a socket for mounting, and locking means for securing. This segmentation allows each component to perform its specific function efficiently while maintaining overall system rigidity through the permanent welding connection.
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 solution significantly stiffens the bracelet, maintaining its original aesthetics by limiting movement between links and ensuring a secure, rigid assembly.
Implementation Method 1
At its other end, it is welded to a socket which is itself secured by locking means inside the blind recess of the side element

AI summary
An item includes at least two sets of assembled elements that are connected to each other by a permanent securing device. The permanent securing device includes a pin mounted in a through hole of a central element of a set. This pin is mounted at each end in a blind recess of a side element belonging to another set. At one end, the pin is secured in the blind recess by a locking device, for example by a screw connection. At its other end, it is welded to a socket which is itself secured by a locking device in the blind recess of the side element.
