RFID Cable System for Sequence Testing Automation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing RFID systems for cable laying operations are prone to failures due to the need for frequent rewriting and incur high costs due to the incorporation of reader functions in terminal blocks, while they primarily focus on connecting operations and do not efficiently address the time and effort-intensive sequence testing process.
Innovation Solution
An RFID system that stores information about the unit of equipment each RFID is attached to and provides the reader function on an operating terminal, allowing for efficient work by eliminating human errors through automated ID reading and LED indications for correct connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If write type RFID is used for cable identification, then the system can store and update wiring information, but the RFID tends to cause failures and requires frequent rewriting which is troublesome
Solution Approach 1:
The patent applies preliminary action by pre-attaching RFID tags to cables during cable installation, storing the cable identification information in advance. This eliminates the need for later rewriting operations, as the RFID data is set once during installation and remains valid throughout the cable's service life, thereby improving reliability while maintaining adaptability.
2Reliability
If reader function is incorporated in terminal block to detect improper wiring, then connection errors can be detected, but the cost increases
Solution Approach 1:
The patent extracts the reader function from the terminal block and relocates it to a portable terminal device. This separation allows the terminal block to remain simple and cost-effective, while the reading and verification functions are performed by an external device during installation and testing, maintaining reliability without increasing manufacturing complexity or cost.
3Reliability
If manual checking operations are performed repeatedly to eliminate human errors, then error detection improves, but the cost increases
Solution Approach 1:
The patent implements automated feedback by having the portable terminal device read RFID tags, automatically verify the wiring information against the work specifications, and provide immediate feedback on correctness. This automated feedback loop replaces manual repeated checking, eliminating human errors while reducing operational costs through efficient automated verification.
4Ease of operation
If traditional manual cable laying operations are performed, then flexibility in handling complex wiring is maintained, but human errors increase
Solution Approach 1:
The patent introduces an intermediary system consisting of RFID tags on cables and a portable terminal device that mediates between the worker and the work specifications. The worker continues to perform manual cable laying operations maintaining flexibility, while the intermediary RFID system automatically tracks and verifies each connection, eliminating human errors without restricting operational flexibility.

AI summary
When an RFID is attached to an object to assist testing operations, the following problems are encountered; (1) the RFID of write type tends to cause a failure and is troublesome due to the necessity of rewrite each time the situation is changed, (2) the incorporation of the reader function in a terminal block increases the cost, and (3) the known techniques are targeted for only the connecting operation and are not adapted for a sequence test that takes the most expense in time and effort. The operations are aided by using an RFID reader and a terminal having the function for accessing a database of circuit information, RFID information, and test procedure information.
