Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used for switches and sensors, then reliable power supply and data transmission are achieved, but installation complexity and safety risks increase in hazardous or temporary locations
Solution Approach 1:
The patent replaces wired mechanical connections with wireless RFID communication and power transfer. The RFID tag embedded in the switch communicates wirelessly with the reader, eliminating the need for physical wiring while maintaining reliable data transmission and power supply in hazardous or temporary locations
2Ease of operation
If wired connections are installed in hazardous locations, then power and control signals can be transmitted, but safety risks and installation disruption increase
Solution Approach 1:
The patent eliminates wired connections in hazardous locations by using wireless RFID technology. The RFID-enabled switch receives power and transmits control signals wirelessly, removing the safety risks associated with exposed wiring in environments with flammable vapors or other hazards
3Duration of action of stationary object
If permanent wiring is provided for switches, then stable power supply is ensured, but adaptability to temporary or changing locations is reduced
Solution Approach 1:
The patent makes the switch system dynamic and adaptable by using wireless RFID technology. The RFID-enabled switch can be easily moved to different locations without permanent wiring, while the reader continuously provides power and communication capabilities, enabling both temporary and permanent installations with equal ease
