Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional RFID tags are used with limited memory and no processing capabilities, then device complexity is low and ease of manufacture is high, but information management capability and adaptability are insufficient
Solution Approach 1:
The RFID tag is divided into multiple independent RF network nodes, each capable of autonomous operation. This segmentation allows the system to achieve advanced information management capabilities while maintaining manufacturing simplicity through modular design and standardized node structures.
Solution Approach 2:
Each RF network node is designed as a universal module that can perform multiple functions including data storage, processing, and communication. This multi-functionality enables the tag to adapt to various information management requirements without increasing overall system complexity.
2Duration of action of moving object
If RFID tags are equipped with batteries or energy harvesting capabilities to enable continuous operation, then duration of action is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The RFID tags harvest energy from the RF signals they receive during normal communication operations. This self-service approach allows the tags to operate continuously without external power sources, batteries, or energy harvesting components, maintaining simplicity while enabling unlimited operational duration.
3Ease of operation
If custom applications are developed to enable data exchange with RFID tags, then information accessibility is improved, but device complexity and integration difficulty increase
Solution Approach 1:
The RF network nodes implement universal networking protocols and interfaces that enable standard data exchange mechanisms. This allows any device with internet connectivity to access RFID tag information without requiring custom applications, significantly improving ease of operation while reducing integration complexity.
Solution Approach 2:
The patent introduces a standardized communication layer between RFID tags and external systems, acting as an intermediary that simplifies data exchange. This mediator enables universal access through standard protocols, eliminating the need for custom applications while maintaining simple tag architecture.
4Adaptability or versatility
If RFID tags are isolated from general internet access to maintain simplicity, then device complexity is low, but adaptability and connectivity to the Internet of Everything are limited
Solution Approach 1:
The system segments network connectivity functionality into independent RF network nodes that can operate autonomously. This allows individual tags to connect to the internet through available RF signals without requiring complex integrated network infrastructure, enabling IoT adaptability while maintaining tag simplicity.
Solution Approach 2:
The RF network nodes implement universal networking capabilities that enable internet connectivity through standard protocols. This multi-functionality allows the tags to participate in the Internet of Everything without increasing their inherent complexity, as the networking capability is inherent in the node design rather than added as a separate system.
