Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical keys and locks are used to enforce sequence, then physical token exchange is achieved, but system complexity and safety reliability are insufficient for hazardous operations
Solution Approach 1:
The patent replaces mechanical keys and locks with an RFID-based electronic token system. The RFID tag stores sequence control data and communicates wirelessly with the reader, eliminating the need for physical token exchange while maintaining sequence enforcement capability. This substitution reduces mechanical complexity and improves reliability through electronic verification.
Solution Approach 2:
The patent introduces an RFID tag as an intermediary carrier that holds sequence control data. Instead of direct mechanical interaction between operators and control systems, the RFID tag mediates the sequence enforcement by storing authorization information that the reader verifies before allowing device operation.
2Adaptability or versatility
If RFID tags are used for sequence control, then wireless communication and data manipulation capabilities are improved, but system implementation complexity increases
Solution Approach 1:
The RFID tag serves multiple functions: it acts as an identification carrier, a sequence control data storage device, and a wireless communication interface. This multi-functionality consolidates what would otherwise require separate mechanical tokens, control systems, and verification mechanisms into a single integrated component.
Solution Approach 2:
The RFID tag contains embedded sequence control data and automatically presents this information to the reader when in proximity. The system performs self-verification of sequence authorization without requiring manual intervention or complex external verification processes.
3Device complexity
If passive UHF RFID tags are used, then system simplicity and cost are reduced, but reading distance and power availability are limited
Solution Approach 1:
The patent uses passive UHF RFID tags that operate with limited power and reading distance, but this is sufficient for the intended application where the tag only needs to communicate sequence control data when in proximity to the reader. The excessive capability of active tags is not required, simplifying the system while meeting functional needs.
