Memory Product Controller Grouping RFID Tags for Multi-Function Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for grouping RFID tags to create multi-function memory products are limited by the need for application program changes and lack of means to check individual tag functionality, leading to restricted functionality and potential application program errors if an abnormal tag is detected.
Innovation Solution
A memory product controller that groups non-contact type memory products, storing identification and operating condition information, allowing for the determination of similar operating conditions across tags and enabling instruction transmission for redundant functionality, thereby allowing for multi-function operation without increasing costs and preventing erroneous operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a plurality of RFID tags are grouped to create multi-function memory products, then the functionality and versatility of the memory product is improved, but the device complexity and difficulty of managing individual tag functionality increases
Solution Approach 1:
The patent introduces a controller as an intermediary device that manages groups of RFID tags. The controller stores group information linking multiple tag IDs to a single group ID, and automatically determines which tags to activate based on operating conditions. This intermediary manages the complexity of coordinating multiple tags, allowing them to function as a unified multi-function memory product without requiring complex application program changes.
2Reliability
If redundant memory products are included in a group to ensure continuous operation, then the reliability of the system is improved, but the cost and quantity of components increases
Solution Approach 1:
The patent implements prior cushioning by pre-configuring redundant memory products within groups and storing their identification information in the controller. When a tag is detected as abnormal or non-responsive, the controller automatically switches to using other tags within the same group that have similar operating conditions. This beforehand preparation ensures continuous operation without requiring additional redundant tags beyond what is already grouped.
3Reliability
If individual tag functionality is monitored and abnormal tags are detected, then the reliability of the system is improved, but the measurement and detection complexity increases
Solution Approach 1:
The patent implements self-service by having each RFID tag automatically respond to reader/writer signals with its identification information. The controller monitors tag functionality by attempting to read these automatic responses and detecting whether tags are responsive. This self-service approach allows for automatic detection of abnormal tags without requiring complex external monitoring systems, as each tag actively participates in its own status verification.
4Adaptability or versatility
If application programs are modified to accommodate grouped memory products, then the adaptability of the system is improved, but the ease of operation and programming complexity increases
Solution Approach 1:
The controller serves as an intermediary that handles the complexity of grouped memory product management, allowing application programs to interact with groups as single logical units. The controller translates high-level group operations into coordinated actions involving multiple individual tags, automatically managing tag selection, activation, and switching based on operating conditions. This intermediary layer shields application programs from the complexity of individual tag management while maintaining full adaptability to grouped configurations.

AI summary
To provide a memory product controller, a memory product control method, and a memory product storing a computer program, capable of realizing a multi-function memory product, without increasing the cost, by grouping a plurality of memory products. In a memory product controller, information identifying a memory product and an operating condition of the memory product are stored in association with information identifying a group, and when reading/writing is performed on one memory product belonging to a predetermined group by a reader/writer for a memory product, reference is made to an operating condition storage unit, and when other memory products having the similar operating condition are present in the same group, instruction information to perform reading or writing on one or a plurality of other memory products belonging to the same group and having the similar operating condition is transmitted to the reader/writer.
