Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID module with integrated LED and NFC chip is used, then reliability and certainty of object identification is improved, but device complexity increases
Solution Approach 1:
The patent combines RFID module, LED, and NFC chip into a single integrated object identification device. The RFID antenna and NFC antenna are integrated within the same device structure, allowing multiple identification and communication functions to be performed simultaneously through one unified device rather than separate components.
Solution Approach 2:
The object identification device performs multiple functions including RFID communication for data storage and retrieval, NFC for near-field communication, and LED for visual identification and status indication. This multi-functional design eliminates the need for separate devices for each function, improving reliability while managing complexity through integration.
2Ease of operation
If LED is added for visual identification, then ease of operation is improved, but use of energy increases
Solution Approach 1:
The LED provides visual identification through light emission, enabling operators to quickly locate and identify objects without complex interfaces. The LED can display different states or colors to indicate object status, enhancing ease of operation through intuitive visual feedback.
Solution Approach 2:
The LED is integrated into the passive RFID device structure, powered by the same electromagnetic field that activates the RFID circuitry. This allows the LED to operate without additional power sources or complex power management systems, as it utilizes the existing power harvesting mechanism of the passive RFID device.
3Adaptability or versatility
If multiple communication protocols (RFID and NFC) are integrated, then adaptability is improved, but device complexity increases
Solution Approach 1:
The device simultaneously supports RFID and NFC communication protocols, enabling it to work with different types of readers and communication systems. This dual-protocol capability allows the same device to be used across various applications and infrastructure types without requiring device changes.
Solution Approach 2:
Both RFID and NFC antennas and circuitry are integrated within the same physical device housing and control architecture. The unified control unit manages both communication protocols, simplifying the overall system design compared to using separate devices for each protocol.
