Traceable Cable Theft Deterrent via Internal Laser Marking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrical wires and cables made of valuable metals like copper and aluminum are often targeted for theft, as they can be sold as scrap metal without being traceable, making it difficult for recycling centers to distinguish between stolen and legitimate materials.
Innovation Solution
A theft deterrent system is implemented by creating unique codes and placing them periodically and longitudinally on the interior of the cable using a laser-based marking system, which can be indexed and traced through a database, ensuring that the cable's ownership can be verified at any point in its lifecycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cable without traceability is used, then manufacturing cost is low and ease of manufacture is high, but the cable is vulnerable to theft and cannot be traced
Solution Approach 1:
The patent applies preliminary action by embedding unique indicia codes into the cable conductor during the manufacturing process, before the cable is installed or put into service. This pre-established traceability system allows for future tracking and identification without requiring additional components or complex external systems to be added later.
Solution Approach 2:
The patent uses an intermediary database system that stores the relationship between unique indicia codes and cable identification information. This database acts as a mediator between the physical cable (with its indicia) and the tracing/verification process, enabling theft prevention without directly modifying the cable's physical structure beyond the simple indicia marking.
2Measurement precision
If unique indicia are placed on cable interior, then traceability is improved, but manufacturing process complexity increases
Solution Approach 1:
The patent replaces complex mechanical traceability systems with a simplified marking system that uses laser-based or inkjet printing to apply unique indicia codes directly to the cable conductor. This substitution of mechanical/embedded tracking devices with a marking-based system significantly reduces manufacturing complexity while maintaining high traceability accuracy.
Solution Approach 2:
The patent changes the parameter of traceability from requiring physical embedded devices to using visual/mark-based identification. By transforming the traceability mechanism from a mechanical/embedded system to a marking system, the manufacturing process becomes simpler while the precision of traceability is maintained through unique code assignment and database recording.
3Loss of information
If database tracking system is implemented, then cable ownership verification is improved, but system complexity and cost increase
Solution Approach 1:
The patent implements a self-service database system where the traceability information is automatically recorded and maintained through the existing manufacturing and installation processes. The unique indicia codes are automatically linked to cable information in the database during manufacturing, and the system automatically tracks ownership transfers and installation locations without requiring complex manual intervention or additional tracking devices.
4Reliability
If indicia are placed periodically and longitudinally on cable, then traceability and theft deterrence are improved, but manufacturing time and complexity increase
Solution Approach 1:
The patent applies periodic action by placing unique indicia codes at regular intervals along the length of the cable. This periodic marking system provides multiple traceability points along the cable, enhancing theft deterrence and traceability accuracy without requiring continuous or excessive marking that would significantly slow production. The periodic placement balances security effectiveness with manufacturing efficiency.

Function Achieved in This Case
This system provides a tamper-resistant and traceable solution that deters theft by ensuring that stolen cables can be identified and traced back to their rightful owners, preventing them from being sold as scrap, thereby reducing theft and ensuring legitimate recycling processes.
Implementation Method 1

AI summary
A theft deterrent cable may be provided. First, a plurality of unique codes may be created. Then a plurality of indicia may be placed periodically and longitudinally on the interior of the cable that may not be viable from the exterior of the cable. The plurality of indicia may respectively correspond to the plurality of unique codes. An indicator may be placed on the exterior of the cable. In a database, the plurality of unique codes may be assigned to an organizational entity. The organizational entity may comprise a first enterprise. Next, an indication that the cable is to be transferred from the first enterprise to a second enterprise may be received. In response to the received indication, the plurality of unique codes may be assigned in the database from the organizational entity comprising the first enterprise to the organizational entity comprising a second enterprise.
