Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional hard-wired flashing methods are used, then reliable software writing is achieved, but device complexity and manufacturing time increase
Solution Approach 1:
The patent replaces the mechanical contact-based flashing interface with a contactless RFID communication system. The RFID reader writer communicates with the programmable integrated circuit through electromagnetic fields without physical connection, eliminating the need for complex hard-wired interfaces and reducing device complexity while maintaining reliable software writing capability
Solution Approach 2:
The patent introduces an RFID interface as an intermediary between the external flashing device and the programmable integrated circuit. This RFID interface includes an RFID reader writer and an RFID tag with antenna, mediating the data transfer through contactless electromagnetic communication, thereby simplifying the overall system architecture
2Quantity of substance
If conventional contact-based flashing is used, then data transmission is achieved, but manufacturing speed and productivity decrease
Solution Approach 1:
The patent enables continuous flashing operations by allowing multiple RFID tags to be processed in sequence without physical reconnection. The contactless nature of RFID communication allows for rapid, continuous data transmission to multiple programmable integrated circuits, significantly improving manufacturing throughput and productivity
Solution Approach 2:
The patent implements pre-programming capability where RFID tags can be programmed with software or configuration data before the programmable integrated circuit is fully assembled or before it needs to be programmed. This preliminary action allows for more efficient production workflows and reduces on-site programming time
3Manufacturing precision
If multiple integrated circuits are programmed individually, then programming accuracy is maintained, but labor and time consumption increase
Solution Approach 1:
The patent creates a universal flashing system that can handle multiple different types of programmable integrated circuits through the standard RFID interface. The system maintains programming accuracy for each individual circuit while enabling batch processing capabilities, allowing multiple circuits to be programmed in rapid succession without sacrificing precision
Solution Approach 2:
The patent segments the flashing process into independent RFID communication transactions, where each programmable integrated circuit can be addressed and programmed individually through the same contactless interface. This segmentation allows for precise control over each programming operation while enabling parallel or sequential processing of multiple circuits
