Embedded RFID Tags in Cable Manufacturing for Asset Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for managing and tracking physical assets in telecommunications networks are prone to errors and inefficiencies due to manual recording processes, environmental damage, and interference issues with RFID tags on curved surfaces, leading to inaccurate and incomplete records, which hinder asset location and maintenance.
Innovation Solution
A method of incorporating RFID tags between layers of flexible material in cable manufacturing, ensuring they are protected and securely attached to the cable core, allowing for accurate and durable identification and location of assets, and a system using a reader with a concave surface to enhance signal coupling for successful reading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RFID tags are placed on the outer surface of cables for easy reading, then accessibility for data capture is improved, but the tags are vulnerable to environmental damage and physical wear
Solution Approach 1:
The RFID tag is nested within the cable structure, specifically positioned between the core and the outer sheath. This nesting protects the tag from environmental damage while maintaining RFID signal accessibility through the cable layers.
Solution Approach 2:
The tag placement moves from a two-dimensional surface application to a three-dimensional integrated position within the cable cross-section. This dimensional change allows the tag to be protected by surrounding cable layers while still being accessible to readers.
2Reliability
If RFID tags are embedded deep within cable layers for protection, then tag durability is improved, but signal coupling and reading accuracy deteriorate
Solution Approach 1:
The cable construction is designed in advance with a designated layer or space for the RFID tag, ensuring optimal positioning for both protection and signal coupling before the cable is fully assembled and deployed.
Solution Approach 2:
The cable layers themselves act as intermediaries that transmit RFID signals from the embedded tag to external readers. The flexible material layers are selected to be RFID-signal transparent while providing mechanical protection.
3Adaptability or versatility
If manual recording processes are used for asset management, then flexibility and adaptability are improved, but human error and data accuracy worsen
Solution Approach 1:
The system enables self-service automated asset management where RFID readers automatically capture and upload asset data to central records without requiring manual data entry by engineers, eliminating human error while maintaining operational flexibility.
Solution Approach 2:
Manual mechanical recording processes are replaced with automated electronic RFID reading and data upload systems. This substitution maintains the flexibility of field operations while dramatically improving data accuracy through automated capture.
4Measurement precision
If extensive manual verification and synchronization processes are implemented, then data accuracy is improved, but time consumption and operational efficiency worsen
Solution Approach 1:
The RFID reading and data upload process operates continuously and automatically during normal cable installation and maintenance activities, eliminating the need for separate verification steps and maintaining constant synchronization between field operations and central records.
Solution Approach 2:
The system provides immediate feedback by automatically uploading RFID captured data to central records in real-time, allowing instant verification and synchronization without manual intervention, thus maintaining data accuracy while preserving operational speed.
