Watch Case Connection Accessory for Connected Bracelets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions fail to adapt connected bracelets with electronic functionalities to classic watch cases, particularly those with mechanical or quartz movements, as they do not ensure proper power supply and electrical connectivity.
Innovation Solution
A connection accessory featuring a cradle made of elastomeric material with inserts and electrical/optical connectors that securely connect to the watch case and bracelet strands, ensuring electrical conduction and sealing, allowing compatibility with any watch case type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a connection accessory is designed to integrate electronic components into bracelet strands, then the functionality of real-time monitoring and communication is improved, but the compatibility with classic watch cases (mechanical or quartz movements) deteriorates due to lack of power supply and electrical connectivity
Solution Approach 1:
The connection accessory acts as an intermediary device that bridges classic watch cases and connected bracelet strands. It includes a cradle assembly that attaches to the watch case and inserts that connect to the bracelet strands, providing electrical connectors that establish circuit closure between the mechanical/quartz watch case and the electronic components in the bracelet strands, enabling power supply and data transmission without requiring modification to the classic watch case
Solution Approach 2:
The connection accessory is divided into separate functional components: a cradle assembly for attaching to the watch case, inserts for connecting to bracelet strands, and electrical connectors for establishing circuit connections. This segmentation allows the accessory to be adapted to different watch case types while maintaining reliable electrical connectivity for electronic functionalities
2Reliability
If the cradle is made of elastomeric material molded over inserts, then the sealing and secure connection are improved, but the manufacturing complexity increases
Solution Approach 1:
The cradle is manufactured by molding elastomeric material directly over the electrical connectors and inserts, combining multiple components (cradle body, sealing elements, and electrical connector housing) into a single integrated piece. This merging of components during the molding process ensures secure connection and effective sealing while actually simplifying manufacturing by reducing the number of separate parts that need to be assembled
