Engineering Contradiction Analysis
1Adaptability or versatility
If electronic locks are used to eliminate mechanical limitations, then access control functionality is improved, but power dependency issues arise
Solution Approach 1:
The patent combines electromagnetic radiation detection technology with traditional mechanical lock structures, merging optical/electronic functionality with mechanical reliability to create a hybrid system that achieves both improved access control and power independence
Solution Approach 2:
The lock system uses electromagnetic radiation from ambient light sources to power its detection and communication components, enabling the device to serve itself without external power sources or batteries, thus eliminating power dependency while maintaining electronic functionality
2Ease of operation
If RFID readers are used for contactless access, then ease of operation is improved, but electromagnetic signals cannot pass through metal surfaces
Solution Approach 1:
The lock system supports multiple access methods including RFID, optical key detection, and mechanical key operation, making it universally compatible with different user needs and overcoming the limitation of RFID signal blockage by providing alternative access pathways
Solution Approach 2:
The patent uses optical radiation as an intermediary medium that can penetrate or reflect off metal surfaces to transmit key information, bypassing the electromagnetic signal blockage problem while maintaining contactless operation capability
3Reliability
If traditional mechanical locks are used, then simplicity and reliability are maintained, but security vulnerabilities and lack of digital recordkeeping exist
Solution Approach 1:
The patent replaces pure mechanical key recognition with electromagnetic radiation detection and optical scanning systems, substituting mechanical information processing with optical/electronic methods that can digitally record and analyze entry data while maintaining mechanical actuation for actuation
