Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional bus systems or Ethernet are used for data transmission, then reliable data exchange between automation components is achieved, but extensive cabling and costly infrastructure installation are required
Solution Approach 1:
The patent replaces mechanical cabling systems with RFID-based wireless electromagnetic field communication. RFID tags and readers enable data transmission without physical connections, eliminating the need for complex bus cables, Ethernet wiring, and associated hardware infrastructure while maintaining data exchange functionality between automation components.
Solution Approach 2:
The patent introduces RFID tags as intermediary data carriers between automation components. These passive tags store and transmit data through electromagnetic fields, acting as a mediator that eliminates the need for direct wired connections between components, thereby reducing infrastructure complexity while ensuring reliable data transmission.
2Reliability
If direct electrical connections are used for data transmission, then secure and reliable communication is achieved, but the system requires extensive network infrastructure and engineering setup
Solution Approach 1:
The patent replaces direct electrical connections with electromagnetic field-based RFID communication. This substitution eliminates the need for physical wiring between automation components and engineering systems, dramatically reducing installation effort while maintaining secure and reliable data transmission through the use of authenticated RFID tags and readers.
