Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an idling structure is added to allow the lock cylinder to automatically idle under unauthorized conditions, then violent unlocking is avoided and safety is improved, but the lock cylinder may still rotate under extreme conditions of high-speed impact or severe vibration, resulting in accidental unlocking
Solution Approach 1:
The patent applies preliminary anti-action by introducing a braking mechanism that proactively counteracts the harmful effect of impact or vibration before accidental unlocking can occur. The braking mechanism includes a braking component, a driving component, and a limiting component that work together to prevent the lock cylinder from rotating under extreme conditions. The braking component can be preliminarily positioned to engage with the driving component, creating a preliminary counter-force that opposes any unintended rotation caused by external impacts or vibrations.
Solution Approach 2:
The patent uses an intermediary approach by introducing a braking mechanism as a mediator between the lock cylinder and external forces. The braking mechanism includes a braking component that acts as an intermediary element, transferring and controlling the interaction between the lock cylinder and external impacts or vibrations. This intermediary structure allows the lock cylinder to idle under unauthorized conditions while preventing rotation under extreme conditions, thus mediating between safety requirements and protection against accidental unlocking.
2Reliability
If the lock cylinder is designed to idle under unauthorized conditions, then violent unlocking is prevented, but the complexity of the lock structure increases due to additional components
Solution Approach 1:
The patent applies merging by integrating the braking mechanism with the existing idling structure and other lock components. The braking component is combined with the driving device and limiting components in a unified structure, where multiple functions are achieved through integrated design. This merging approach allows the lock cylinder to maintain its idling capability while incorporating braking functionality, thereby protecting against violent unlocking without proportionally increasing structural complexity.
Solution Approach 2:
The patent implements multi-functionality by designing the braking mechanism to serve multiple purposes within the lock system. The braking component not only prevents accidental unlocking under extreme conditions but also works in conjunction with the idling structure to prevent violent unlocking. The driving component and limiting component also contribute to both the idling function and the braking function, creating a multi-functional system that achieves enhanced protection without proportionally increasing complexity.
