Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional communication systems (GSM-R, CBTC, wayside devices) are used for information exchange between guided vehicles, then information can be transmitted, but the system complexity increases and driver intervention is required
Solution Approach 1:
The patent replaces complex mechanical/electronic communication systems (GSM-R, CBTC, wayside devices) with an RFID-based electromagnetic field communication system. The RFID reader and tag use electromagnetic coupling to exchange data wirelessly when vehicles cross, eliminating the need for complex communication infrastructure and driver intervention while maintaining reliable information transfer.
Solution Approach 2:
The RFID tag acts as an intermediary carrier that stores and transfers information between vehicles. Instead of direct vehicle-to-vehicle communication or vehicle-to-control-center communication, the tag serves as a portable data repository that the reader can access when vehicles cross, simplifying the communication architecture.
2Reliability
If traditional communication systems are used, then information exchange can occur, but driver intervention is required which reduces automation
Solution Approach 1:
The communication system operates autonomously without driver intervention. The RFID reader automatically detects and reads tags on crossing vehicles, and the ICM automatically processes the exchanged information. The system serves itself by utilizing the natural crossing motion of vehicles to enable communication, eliminating the need for manual activation or monitoring.
3Reliability
If traditional communication systems are used, then information can be exchanged, but the cost increases
Solution Approach 1:
The RFID tags are inexpensive, simple devices that can be easily manufactured and deployed on vehicles. Unlike expensive GSM-R base stations or CBTC infrastructure, RFID tags are low-cost components that require minimal installation complexity, making the overall system more cost-effective while maintaining reliable communication.
