Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Human error in implementing and maintaining physical cable connections in communications networks can lead to significant negative impacts, highlighting the need for improved control and verification of network cable installation and removal work orders, as well as a clear guidance system for technicians during moves, adds, and changes (MACs) in patch fields.
Innovation Solution
The implementation of 'ten-wire' patch cords with additional conductors for management, equipped with light-emitting diodes (LEDs) and circuitry within the plugs to provide visual guidance and detection of patch cord connections, enabling easy-to-follow instructions for technicians during installations and removals in cross-connect deployments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional patch cords without management conductors are used, then the device complexity is low, but the reliability of patch cord installation and maintenance is poor due to human error
Solution Approach 1:
The patent introduces an intermediary detection system consisting of ninth and tenth conductors that mediate between the patch cord and patch panel. These conductors carry detection signals to verify proper connection, acting as a mediator that enables automated verification without disrupting the primary data transmission function of the traditional eight conductors.
Solution Approach 2:
The patent implements feedback mechanisms where the detection circuitry continuously monitors the electrical connections through the ninth and tenth conductors and provides real-time feedback about connection status. This feedback enables automated verification and alerts technicians to installation errors, improving reliability through continuous monitoring rather than relying on manual verification.
2Ease of operation
If visual guidance systems are added to patch cords, then the ease of operation for technicians is improved, but the device complexity increases due to additional conductors and circuitry
Solution Approach 1:
The patent employs color changes through LED indicators that change color or illuminate to provide visual guidance to technicians during MAC procedures. The detection circuitry uses different lighting states to indicate connection status, guiding technicians through proper installation steps without requiring complex interfaces or multiple components.
Solution Approach 2:
The system provides self-service capabilities where the patch panel and detection circuitry automatically guide technicians through installation procedures without requiring external assistance or complex manual verification processes. The visual indicators and automated detection enable technicians to independently complete MAC procedures correctly.
3Productivity
If automated detection systems are implemented, then the productivity of network maintenance is improved, but the device complexity increases due to additional management conductors
Solution Approach 1:
The patent segments the conductor functions by dedicating specific conductors (ninth and tenth) exclusively to detection and management purposes, while the traditional first through eighth conductors handle data transmission. This segmentation allows the detection system to operate independently without interfering with data communication, enabling automated detection without requiring complete system redesign.
Solution Approach 2:
The patent achieves multi-functionality where the patch cord and patch panel serve dual purposes: the first through eighth conductors handle data transmission while the ninth and tenth conductors provide detection and management functions. This universal design allows a single cable assembly to perform both data communication and automated verification without requiring separate dedicated cables.

AI summary
An intelligent network patch field management system and specialized cross-connect cable are provided to help guide, monitor, and report on the process of connecting and disconnecting patch cords plugs in a cross-connect patching environment. The system is also capable of monitoring patch cord connections to detect insertions or removals of patch cords or plugs. The cross-connect cable is provided with LED's in both of the cable plugs. When only one plug of the cross-connect cable is plugged into a port, the LED associated with that plug is switched out of the circuit, while the LED in the unplugged plug remains in the circuit and can still be illuminated by the system.
