Fiber Optic Cable RFID Labeling for Accurate Segment Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cable tracking and inventory management systems are prone to errors and inefficiencies, particularly in identifying and tracking individual cables within vast quantities, leading to overstocking, stockouts, and difficulty in locating defective cables, especially when installed across diffuse areas.
Innovation Solution
A cable labeling system with electronic tags at predetermined intervals along the length, allowing for real-time tracking and scanning, combined with a cable database for precise inventory management and installation verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual tracking methods are used for cable inventory management, then implementation simplicity is maintained, but accuracy and reliability of tracking deteriorate due to human errors
Solution Approach 1:
The patent replaces manual mechanical tracking methods with electronic RFID tags and automated scanning systems. The RFID tags embedded in cables enable automatic identification and tracking, eliminating human error in manual record-keeping while maintaining system accessibility through simple scanner devices.
Solution Approach 2:
The patent creates a digital copy of cable information through RFID tags that store and transmit cable identification data. This digital representation allows for accurate tracking and inventory management without requiring physical inspection or manual documentation of each cable.
2Ease of operation
If cables are installed across diffuse areas without precise tracking, then installation flexibility is improved, but the ability to locate and replace defective cables deteriorates
Solution Approach 1:
The patent implements a feedback system where RFID tags on installed cables continuously provide location and identification information to a central database. This enables real-time tracking of cable positions across diffuse areas, allowing technicians to quickly locate and replace defective cables while maintaining installation flexibility.
Solution Approach 2:
The patent introduces RFID tags as intermediaries between the cable infrastructure and the tracking system. These tags enable indirect detection and location of cables in diffuse areas without requiring direct physical access or visual inspection, solving the problem of locating cables installed in hard-to-reach or extensive areas.
3Quantity of substance
If discrete lengths of cable are cut from a single spool and installed in several locations without tracking, then material utilization is improved, but inventory accuracy deteriorates leading to overstocking or stockouts
Solution Approach 1:
The patent applies segmentation by assigning unique RFID tags to discrete cable segments cut from a single spool. Each segment maintains its own identification, allowing the system to track individual pieces through inventory and installation processes. This enables accurate inventory management of cable segments while maintaining efficient material utilization from the original spool.
Solution Approach 2:
The patent implements preliminary action by tagging cable segments with RFID identifiers before they are cut from the spool and during the installation process. This pre-tagging enables the system to track and account for each segment's location and status, preventing inventory inaccuracies that would otherwise result from untracked cable distribution.

AI summary
A cable has a first end and a second end with a length of the cable being defined between the first end and the second end. The cable includes an outer jacket, a plurality of internal lines disposed within the outer jacket, and a plurality of label secured at predetermined intervals along the length of the cable. Each label of the plurality of labels includes an electronic tag configured to communicate with a scanner external to the cable. Each electronic tag has information relevant to the cable stored thereon. The information relevant to the cable includes at least a unique serial number associated with each respective electronic tag.
