Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID systems use traditional electromagnetic coupling for remote data storage and retrieval, then line of sight connection is precluded, but the ability to selectively set voltage or current levels on electronic devices is lost
Solution Approach 1:
The patent combines RFID electromagnetic coupling capability with direct electrical communication interface in a single device. The RFID device includes both antenna elements for wireless communication and electrical interface elements (pins, pads, or connectors) for direct electrical connection, allowing simultaneous achievement of remote data access and voltage level control functionality
Solution Approach 2:
The RFID device is designed to perform multiple functions: traditional RFID data storage and retrieval via electromagnetic coupling, plus the additional capability of selectively setting voltage or current levels on electronic devices through direct electrical communication. This multi-functional design resolves the contradiction by making the device adaptable to both remote access and precise electrical control applications
2Adaptability or versatility
If RFID device establishes direct electrical communication with electronic device, then voltage or current level control is achieved, but device complexity increases
Solution Approach 1:
The patent integrates the electrical communication interface directly into the RFID device structure, combining wireless RFID functionality with wired electrical control capability in a single unified device rather than requiring separate components, thereby managing complexity through integration
Solution Approach 2:
The electrical interface is designed to be universal, supporting multiple voltage levels (at least three different levels) and applicable to various electronic devices, which reduces the need for device-specific customization and manages complexity through standardized multi-functional design
