Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic locks are used to provide access control, then security and flexibility are improved, but device complexity and power consumption increase
Solution Approach 1:
The patent replaces complex electronic control systems with a simplified mechanism that uses a conventional mechanical door latch lock combined with a wireless communication device. The mechanical lock's rotational motion is leveraged to activate a switch, which triggers the wireless transmission of an access code, eliminating the need for complex electronic locking mechanisms while maintaining security.
Solution Approach 2:
The patent extracts the essential security function from complex electronic lock systems and isolates it into a simple wireless code transmission mechanism. By separating the access control function into a standalone wireless communication component that works with existing mechanical locks, the system achieves security without the complexity of integrated electronic locking systems.
2Extent of automation
If motor-driven mechanisms are added to duplicate mechanical lock functionality, then electronic access control is achieved, but simplicity and cost-effectiveness are lost
Solution Approach 1:
The patent enables the existing mechanical door latch lock to serve dual purposes: its primary mechanical locking function and its secondary function of activating the wireless communication device through its rotational motion. This self-service approach eliminates the need for separate motor-driven mechanisms, as the mechanical lock itself triggers the electronic access control function.
Solution Approach 2:
The patent makes the conventional mechanical door latch lock multi-functional by designing it to not only perform mechanical locking but also to activate a switch through its rotational motion, thereby triggering wireless code transmission. This universal application of the mechanical lock eliminates the need for additional motor-driven components.
3Ease of operation
If wireless communication devices are integrated with mechanical locks, then contactless access control is achieved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the access control system into two independent but cooperative components: the existing mechanical door latch lock and a separate wireless communication device. The mechanical lock's rotational motion activates a switch that triggers the wireless device to transmit the access code. This segmentation allows each component to be manufactured and tested independently, reducing overall manufacturing complexity.
Solution Approach 2:
The patent introduces a simple switch as an intermediary component that bridges the mechanical and wireless domains. The rotational motion of the mechanical lock activates the switch, which in turn triggers the wireless communication device. This intermediary simplifies the integration process by providing a straightforward mechanical-to-electrical connection without requiring complex coupling mechanisms.
