Smart Patch Cord Management via Embedded RFID Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current patch cord documentation systems for interconnect network configurations require retrofit installations with various parts, making them complex and disruptive to existing networks, and lack real-time monitoring and change notification capabilities.
Innovation Solution
A patch cord management system that uses smart patch cords with embedded identification information, readable by intelligent patch panels, which guide installation and removal processes through indicator lights and automatic database association with Ethernet switches, enabling real-time monitoring and minimal disruption to existing networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If retrofit contact plates and scanning systems are installed on switches and patch panels, then patch cord documentation capability is improved, but device complexity and installation disruption increase
Solution Approach 1:
The patent extracts the identification function from the switch and patch panel infrastructure, placing it instead in the patch cords themselves through embedded RFID tags. This removes the need for complex contact plates and scanning systems on the switch infrastructure, thereby reducing device complexity while maintaining documentation capability.
Solution Approach 2:
The patent introduces RFID tags as intermediary elements embedded in patch cords to carry identification information. These tags serve as mediators between the patch cord physical connection and the documentation system, eliminating the need for direct integration with switch contact plates and reducing overall system complexity.
2Loss of information
If retrofit contact plates and scanning systems are installed on switches and patch panels, then patch cord documentation capability is improved, but installation disruption and time increase
Solution Approach 1:
The patent applies preliminary action by embedding RFID tags in patch cords during the cord manufacturing process, before installation. This eliminates the need for retroactive installation of identification systems in existing networks, significantly reducing installation time and disruption while ensuring documentation capability is already present.
3Loss of information
If traditional patch cord documentation systems are used, then connection tracking is improved, but real-time monitoring and change notification capabilities are lost
Solution Approach 1:
The patent implements feedback mechanisms where the network management system continuously queries RFID tags in patch cords and automatically notifies administrators of connection changes. This creates real-time monitoring capability that enhances reliability by providing immediate awareness of connection status changes rather than relying on periodic or manual updates.

AI summary
A network documentation and revision system is presented that includes first and second devices connected by a patch cord. The first device has provisioning and signal ports with corresponding contact assemblies. The second device has a switch port without a contact assembly. The patch cord has signal and control wires, a first connector that connects the signal wires into a signal port and the control wire to a corresponding contact assembly, and a second connector that connects the signal wires to the switch port and terminates the control wire. The second connector contains an indicator controlled by control circuitry, detection circuitry detecting whether the second connector is plugged into the second device, and ID circuitry providing an ID number through the first connector. Installation or removal of the patch cord is guided by indicators on the patch cord and first device without retrofit contacts being added to the second device.
