Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a battery is used to power the electronic lock, then the lock can operate independently without wiring, but the battery will degrade over time and require replacement
Solution Approach 1:
The electronic lock system performs self-charging through inductive coupling with the power source in the frame. The receiving coil in the bolt automatically receives power wirelessly when the door is closed and positioned near the transmitting coil, eliminating the need for manual battery replacement or external wiring connections.
2Reliability
If wiring is integrated into the frame or traverses the hinged portion, then continuous power supply is achieved, but the installation complexity and potential points of failure increase
Solution Approach 1:
The patent replaces the mechanical wiring system with an electromagnetic field-based inductive power transfer system. The transmitting coil in the frame and receiving coil in the bolt create a wireless power connection that eliminates physical wires, connectors, and wiring pathways through the hinged portion, reducing mechanical complexity while maintaining continuous power supply.
3Use of energy by moving object
If traditional battery replacement is used, then power replenishment is achieved, but maintenance time and user inconvenience increase
Solution Approach 1:
The electronic lock system automatically recharges its internal battery through inductive coupling with the power source in the frame. When the door is closed and the bolt is positioned near the transmitting coil, power is transferred wirelessly to replenish the battery without requiring user intervention, eliminating maintenance time and inconvenience.
