Visual RFID Tags for Asset Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and limited versatility of RFID tag systems, particularly in monitoring moving assets and retail applications, due to the need for numerous readers and hard-wired components, make them prohibitively expensive and inefficient.
Innovation Solution
The development of dynamic visual RFID tags with internal energy sources, low-power microcontrollers, and wireless communications modules, along with edge readers and mesh networks, allows for self-powered displays that can update information without hard-wired connections, extending read ranges and reducing installation costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID tags are used to monitor moving assets in manufacturing or logistic applications, then asset tracking capability is improved, but system cost increases prohibitively due to the need for many hard-wired readers and network components
Solution Approach 1:
The visual RFID tag incorporates an internal power source (battery or energy harvesting components) that enables the tag to power its own display and communication functions without external wiring. This self-powered design eliminates the need for hard-wired connections to readers and network components, significantly reducing installation complexity while maintaining reliable asset tracking capability.
2Loss of information
If RFID tags are used in retail store shelf applications with displays, then real-time visual feedback capability is improved, but system cost increases prohibitively due to the need for many hard-wired readers and displays
Solution Approach 1:
The visual RFID tag includes an internal power source that enables the display to operate autonomously without hard-wired connections to readers or power sources. This self-powered architecture allows multiple tags to be deployed on retail shelves with minimal infrastructure, reducing network installation complexity while providing real-time visual feedback on product information, pricing, and availability.
3Area of stationary object
If the interrogation and read range of RFID tag readers is extended, then coverage area is improved, but the number of readers required decreases, reducing system cost
Solution Approach 1:
The invention merges the RFID tag functionality with a visual display and an internal power source into a single integrated unit. This combination eliminates the need for separate readers in many applications, as the tags can autonomously communicate their status and be detected over extended ranges, reducing the total number of readers required while expanding effective coverage area.
