Wearable Strap Connection Module Pin Holder Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable device straps made of non-metallic materials like urethane, silicone, carbon, leather, or fabric are prone to tear or wear from repetitive use and frequent swapping, and tools used for removing them can damage or deform the straps.
Innovation Solution
A wearable device with a connection module that includes a connection pin portion and a holder portion, where the connection pin portion is inserted into the holder portion to couple and decouple the strap from the body, preventing damage and facilitating easier installation and removal without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection methods are used, then the strap can be removed and installed, but the strap is vulnerable to tear or wear from repetitive use
Solution Approach 1:
The connection module is divided into separate functional components: a connection pin portion for coupling and a holder portion for retention. This segmentation allows the strap to be easily detached and reattached without tools while distributing the mechanical stress away from the strap material itself, preventing wear and tear during repetitive use.
Solution Approach 2:
The connection module acts as an intermediary mechanism between the strap and body portion. Instead of directly attaching the strap to the body, the connection pin and holder portion mediate the coupling, providing a protected interface that prevents direct stress on the strap material while enabling easy removal and installation.
2Ease of operation
If tools are used for releasing the straps, then the strap can be removed, but the strap may be damaged or deformed
Solution Approach 1:
The connection module is designed to be self-releasing through a simple pulling motion on the connection pin portion. The holder portion automatically releases the connection pin when pulled, eliminating the need for external tools and preventing damage to the strap material during the removal process.
Solution Approach 2:
The connection pin portion is extracted as a separate, movable component from the holder portion. This extraction allows the connection pin to be freely moved and removed from the holder through simple pulling, enabling tool-free strap removal while the holder portion remains stationary and protected.
3Ease of operation
If the connection pin portion is made movable for easy coupling, then installation is facilitated, but the connection pin may become loose or detached
Solution Approach 1:
The connection pin portion is designed with dynamic characteristics, allowing it to move freely along the guide hole for easy coupling while the stopper portions provide dynamic constraint to prevent excessive movement. This dynamic design enables simple installation while maintaining connection stability through the stopper mechanism.
Solution Approach 2:
The connection pin portion has different functional qualities at different locations: the guide hole provides local guidance for movement during coupling, while the stopper portions provide local constraint to prevent loosening. This local differentiation of functional qualities allows the connection pin to be both movable for ease of coupling and constrained for connection stability.
