Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an electronic lock uses an integrated battery, then it can operate independently, but the battery will run out of energy and require replacement
Solution Approach 1:
The patent removes the battery component entirely from the electronic lock system. Instead of integrating a battery that requires replacement, the system extracts the power source function and relocates it to an external mobile device, eliminating the reliability issue of battery depletion
Solution Approach 2:
The mobile device serves multiple functions: it acts as the power source for the electronic lock, the authentication device for user verification, and the communication interface for transmitting unlock commands. This multi-functionality eliminates the need for separate battery, keypad, and display components
2Reliability
If an electronic lock removes integrated batteries, then continuous operation is achieved, but the system requires external power sources
Solution Approach 1:
The electronic lock system includes an intermediary power receiving unit that interfaces between the mobile device's power output and the lock's internal electromagnetic device. This intermediary component simplifies the power supply architecture by providing a standardized interface for external power sources
