Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If conventional RFID tags use passive power design without batteries, then power consumption is eliminated and device complexity is reduced, but processing capabilities, memory, and connectivity are limited
Solution Approach 1:
The RFID tag performs self-powering by harvesting energy from the RF signals it receives during normal communication operations. The power management circuit converts the received RF energy into electrical power to operate the processor, memory, and communication functions without requiring external battery power or grid connection.
2Adaptability or versatility
If RFID tags are designed with enhanced processing capabilities and memory, then functionality and adaptability are improved, but power requirements increase and grid connection or batteries become necessary
Solution Approach 1:
The system achieves self-sufficiency by capturing and converting RF energy from the communication environment to power all enhanced functions including processor operations, memory access, wireless communication, and sensor interfaces, eliminating the need for external power sources despite increased functionality.
3Use of energy by moving object
If RFID tags are isolated from the Internet due to power constraints, then power consumption is minimized, but integration with the Internet of Everything is hindered
Solution Approach 1:
The RFID tag incorporates multiple communication interfaces including wireless transceivers for Internet connectivity, RFID readers/writers for data exchange, and sensor interfaces for environmental monitoring, enabling the device to perform diverse functions and integrate into the Internet of Everything ecosystem while maintaining passive power operation.
4Ease of operation
If custom applications are developed to interact with RFID tags, then data exchange capability is improved, but device complexity and ease of operation worsen
Solution Approach 1:
The RFID tag includes built-in RFID reader and writer capabilities along with sensor interfaces and wireless communication functions, allowing it to interact with various systems and devices using standard protocols without requiring custom application development, thereby simplifying operation while maintaining versatility.
