Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotating bezel systems for timepieces with integrated communication circuits are complex and insecure, as they require multiple components and are easily disassembled, posing risks to the communication devices and data they contain.
Innovation Solution
A bezel system with a groove for the communication circuit over-moulded with a polymer material, optionally including a dial train element with excess thickness areas for index numbers, providing a secure and sealed assembly that enhances security and simplicity by using a single piece design and non-contact communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication circuits are integrated into the bezel using a slot with cover and separate antenna, then communication functionality is achieved, but device complexity increases and security decreases
Solution Approach 1:
The communication circuit and antenna are integrated directly into the bezel structure itself, eliminating the need for separate slots, covers, and component assemblies. The bezel serves dual purposes as both a structural element and a communication device housing, reducing overall complexity.
Solution Approach 2:
The bezel is designed to perform multiple functions: it serves as the rotational timing indicator, the structural frame, and the integrated housing for communication circuits and antenna. This multi-functionality eliminates the need for separate dedicated spaces for communication components.
2Adaptability or versatility
If communication circuits are integrated into the bezel using a slot with cover, then communication functionality is achieved, but the system becomes easy to disassemble for data retrieval
Solution Approach 1:
The communication circuit is permanently integrated into the bezel structure through over-moulding, making it impossible to access without destroying the bezel itself. The circuit board becomes an inseparable part of the rotational indicator, ensuring data security.
Solution Approach 2:
The polymer over-moulding creates a sealed, permanent encapsulation of the communication circuit within the bezel structure. This flexible yet durable material provides both protection and permanent integration, preventing unauthorized access to the circuit.
3Stability of the object's composition
If the slot is filled with resin to restrict movement, then component stability is improved, but device complexity and assembly steps increase
Solution Approach 1:
The communication circuit is positioned and fixed within the bezel during the over-moulding process itself, before final assembly. The polymer material is injected to automatically fill and secure the circuit in place, eliminating the need for separate resin filling and stabilization steps.
Solution Approach 2:
The mounting structure and stabilization function are merged into the single over-moulding operation. The polymer material simultaneously provides structural integration, mechanical fixing, and environmental sealing in one process step.
