RFID Tag Workflow Management for Offline Process Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing workflow management systems struggle to accurately manage the progress of processes in a workflow, especially in environments where post-processing apparatuses operate offline and are not connected to the network.
Innovation Solution
A method utilizing RFID tags that can be read in a non-contact state, where these tags are attached to products moving through various processes. The system detects the RFID tags, manages the progress of processes, and provides notifications based on the comparison between the detected tag location and the managed processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If post-processing apparatuses operate offline without network connection, then device complexity is reduced and ease of operation is improved, but process progress management becomes inaccurate and information loss occurs
Solution Approach 1:
An RFID tag serves as an intermediary carrier that physically moves with the product through the workflow. The tag stores and transmits process information between offline apparatuses, enabling information exchange without requiring network connections. This mediator allows accurate process progress tracking while maintaining the simplicity of offline operation.
2Measurement precision
If RFID tags are used for non-contact reading, then measurement precision and detection capability are improved, but device complexity increases
Solution Approach 1:
The RFID tag is a passive component that automatically responds to reader queries without requiring power or complex processing. The tag self-services by storing product and process information and transmitting it when queried, eliminating the need for active components in the tagging system and reducing overall device complexity while maintaining high detection precision.
3Adaptability or versatility
If workflow progress is tracked through multiple offline apparatuses, then adaptability to distributed environments is improved, but loss of time in coordination and notification occurs
Solution Approach 1:
The RFID tag continuously carries process information as the product moves through the workflow, enabling uninterrupted tracking across offline apparatuses. The notification system continuously monitors tag positions and automatically alerts when processes complete, eliminating coordination delays and maintaining continuous useful action throughout the distributed workflow.

a tag from which information can be read in a noncontact state is provided to be movable together with a product
Data Source
AI summary
In a management system, a tag from which information can be read in a noncontact state is provided to be movable together with a product obtained by an apparatus corresponding to each process forming a workflow. The management system detects the tag arranged in association with the apparatus; manages progress of the processes in the workflow; and performs a notification concerning the progress of the processes in the workflow based on comparison between a process where the detected tag is located and the progress of the managed processes.
