Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a coded lock with numerical password is used, then the lock can be operated simply, but the security is low and the password can be obtained through multiple trials
Solution Approach 1:
The patent replaces the traditional mechanical coded lock system with an electronic lock system that uses a sensor to receive optical control signals and a circuit board to process signals and control the lock cylinder. This substitution eliminates the numerical code entry mechanism and provides enhanced security through electronic authentication while maintaining ease of operation through optical signal recognition.
2Ease of manufacture
If the initial password is set to '000' for simplicity, then the lock is easy to set up, but the password is easily forgotten after long time
Solution Approach 1:
The electronic lock system automatically manages password storage and retrieval through its circuit board and sensor components. The system eliminates the need for users to manually remember numerical codes by using electronic memory to store authentication data, thereby preventing password遗忘 while maintaining easy setup through automated initialization.
3Device complexity
If a mechanical coded lock is used, then the structure is simple, but the function is limited to only open and closed states
Solution Approach 1:
The patent integrates multiple functions into the electronic lock system including optical signal reception, electronic signal processing, lock cylinder control, and potential GPS positioning and weak current reminder functions through the circuit board. This multi-functional design expands beyond simple open/closed states while maintaining a relatively compact structure by consolidating multiple functions in integrated electronic components.
4Device complexity
If the lock cylinder assembly is mounted outside the lock body, then the structure is simple, but the lock can be illegally unlocked by other methods
Solution Approach 1:
The patent nests the lock cylinder assembly inside the lock body housing, creating a protected internal structure. This nesting arrangement prevents unauthorized access to the lock cylinder from external methods while maintaining structural integrity through the housing enclosure, thereby enhancing security without significantly increasing overall complexity.
