Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modular watch design with detachable display module and movement module is used, then ease of customization is improved, but water resistance reliability deteriorates
Solution Approach 1:
The patent replaces traditional mechanical sealing systems with magnetic sealing. Magnetic O-rings and magnetic gears create water-tight seals through magnetic attraction forces, eliminating the need for complex mechanical sealing components and allowing reliable water resistance while maintaining modular detachable connections between display and movement modules
2Adaptability or versatility
If detachable display module is used, then ease of customization is improved, but hand synchronization reliability deteriorates
Solution Approach 1:
The patent replaces traditional mechanical gear connections with magnetic gear coupling. The magnetic gears transmit rotational motion and maintain synchronization between display hands and movement module without requiring physical mechanical connections that would complicate assembly and disassembly operations
Solution Approach 2:
The magnetic gear mechanism serves multiple functions simultaneously: it transmits rotational motion, maintains hand synchronization, and provides water-tight sealing all through a single integrated component system, eliminating the need for separate mechanical connection mechanisms
3Adaptability or versatility
If multiple axes extend outside the watch module, then modularity is improved, but water resistance deteriorates
Solution Approach 1:
The patent uses magnetic O-rings to seal around axes and connection points where modules detach. The magnetic sealing system maintains water resistance even with multiple external axes and connection points, as the magnetic attraction creates continuous sealing contact without requiring complex mechanical seal arrangements
