Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional fixed locking mechanism is used, then the structure is simple, but the reliability and adaptability are insufficient
Solution Approach 1:
The locking lug is designed to be movable rather than fixed, allowing it to shift position along the lever spindle axis. This dynamic component can move between engaged and disengaged positions, enabling the lock to adapt to different operational states while maintaining reliable locking when engaged.
Solution Approach 2:
A resilient member (spring) acts as an intermediary element between the electric actuator and the locking lug. This spring mediates the force transmission, providing controlled movement of the locking lug while ensuring it returns to its engaged position, thereby enhancing reliability without requiring complex control mechanisms.
2Adaptability or versatility
If a movable locking lug is used, then the adaptability and reliability are improved, but the device complexity increases
Solution Approach 1:
The movable locking lug serves multiple functions: it provides secure locking when engaged, allows controlled movement during operation, and automatically returns to its engaged position through the resilient member. This multi-functionality enhances adaptability while minimizing the need for separate components.
Solution Approach 2:
The resilient member automatically returns the locking lug to its engaged position without requiring external control signals or additional actuation. This self-service mechanism simplifies the overall control system while maintaining high adaptability and reliability.
3Reliability
If a resilient member is added to move the locking lug, then the reliability is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The resilient member introduces elastic deformation as a key parameter in the locking mechanism. By utilizing the elastic properties of the spring, the system achieves reliable automatic return of the locking lug while the spring can be manufactured using standard elastic component fabrication processes.

Data Source
AI summary
A lock assembly is disclosed to lock a moveable structure to a fixed structure. The lock assembly includes an electric actuator operable to move a locking lug between first and second axial positions to correspond with a locked and unlocked configuration of the lock assembly. A resilient member can couple the locking lug to the electric actuator and drive the locking lug between the first and second positions.
