Adaptive RFID Tag Processing via Executable Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional RFID systems are limited in their ability to process information from RFID tags with unknown behavior patterns, as the behavior pattern between the RFID tag and reader must be predefined, leading to inefficiencies in adaptive and intelligent information processing, especially in open environments with multiple objects having different kinds of RFID tags.
Innovation Solution
Incorporating executable content in RFID tags that can be transmitted to a proxy device, which processes and executes this content, allowing the RFID reader to adapt and provide intelligent information processing without prior knowledge of the tag's behavior pattern, enabling flexible and adaptive RFID systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID systems use predefined behavior patterns for tag processing, then system reliability is improved, but adaptability deteriorates
Solution Approach 1:
The patent implements dynamic behavior patterns where the RFID system can adapt its processing logic at runtime based on tag characteristics. The reader device dynamically selects and executes appropriate behavior patterns from a library based on real-time tag identification, rather than relying on static pre-defined patterns. This allows the system to maintain reliability through structured processing while achieving adaptability through dynamic pattern selection.
Solution Approach 2:
The RFID tag transmits its own behavior pattern information to the reader, enabling the tag to essentially program its own processing requirements. The tag includes executable instructions or behavior pattern identifiers that automatically guide the reader's processing actions, eliminating the need for external pre-configuration and enabling the system to self-adapt to different tag types.
2Adaptability or versatility
If RFID systems support multiple tag types with different behavior patterns, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The reader device is designed with universal processing capabilities that can handle multiple tag types through a unified architecture. Instead of requiring separate processing logic for each tag type, the system uses a single reader that dynamically adapts its behavior based on the transmitted behavior pattern information, achieving multi-functionality without proportional increases in complexity.
Solution Approach 2:
The behavior pattern acts as an intermediary that mediates between the diverse tag types and the reader's processing logic. Rather than the reader directly handling complex variations in tag behavior, the behavior pattern information serves as a standardized interface that translates diverse tag requirements into uniform processing instructions, reducing the reader's structural complexity.
3Ease of operation
If RFID systems require predefinition of behavior patterns, then ease of operation is improved, but productivity deteriorates
Solution Approach 1:
The behavior pattern information is prepared in advance and stored within the RFID tag during manufacturing or programming. This preliminary action embeds the processing instructions directly in the tag, so that during operation, the reader simply needs to retrieve and execute these pre-prepared patterns, maintaining ease of operation while eliminating the need for time-consuming pre-configuration and enabling rapid processing of diverse tags.
