Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elastic member is used to reset the pull ring in the unlocking device, then the unlocking function can be achieved, but the structure becomes complicated and the reliability deteriorates due to loss of elastic force over time
Solution Approach 1:
The patent removes the elastic member from the unlocking device structure. The pull ring is no longer reset by elastic force but by a different mechanism that does not rely on elastic components, thereby eliminating the reliability issue of elastic force degradation while maintaining the unlocking function.
Solution Approach 2:
The patent replaces the elastic-based mechanical reset mechanism with an alternative mechanical system that uses a different principle (not relying on elastic deformation) to achieve the pull ring resetting function, thus improving reliability without sacrificing operational capability.
2Ease of operation
If an elastic member is used in the unlocking device, then the pull ring can be reset, but the overall structure becomes complicated
Solution Approach 1:
The elastic member is extracted from the unlocking device structure. The patent achieves pull ring resetting through a simplified mechanism that does not include elastic components, thereby reducing structural complexity while maintaining the resetting function.
3Ease of manufacture
If traditional elastic structures are used in the optical module, then the locking function can be achieved, but the cost increases and stability deteriorates
Solution Approach 1:
The patent eliminates elastic structures from the optical module's locking mechanism. The locking function is achieved through a different mechanical approach that does not rely on elastic components, thereby improving stability and reliability while maintaining manufacturability.
4Ease of operation
If elastic components are included in the optical module design, then the unlocking mechanism can function, but the cost increases
Solution Approach 1:
The patent removes elastic components from the optical module design. The unlocking mechanism is restructured to function without these components, thereby reducing manufacturing cost while maintaining the essential unlocking functionality.
