Solution Overview

Problem

As data centers become denser, managing cables becomes increasingly difficult due to the need for multiple connections between devices in different racks, leading to space inefficiency and increased complexity, as patch panels are required to transfer connections between racks, resulting in extra cables and cluttered cable trays.

Innovation Solution

A demarcation device is mounted on top of cable trays, featuring a frame assembly and base that allows for perpendicular installation, enabling efficient termination of external cables and routing of internal cables without obstructing the tray, thereby reducing the need for additional cables and optimizing space usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If patch panels are used to transfer connections between racks, then device connectivity is achieved, but cable complexity and tray clutter increase

Engineering Contradiction:
Improvedevice connectivityVSAvoidcable complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The invention extracts the cable management function from traditional patch panels and relocates it to the cable tray level using demarcation devices. This separates the connectivity function (remaining in racks) from the cable routing function (moved to tray), eliminating the need for intermediate patch panels and reducing overall system complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention transitions cable management from a vertical rack-based dimension to a horizontal tray-based dimension. By implementing demarcation devices in the cable tray plane rather than in rack units, the system reorganizes cable paths horizontally before vertical rack connections, reducing cable complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If multiple cables are routed through cable trays to connect devices in different racks, then device connectivity is achieved, but space efficiency decreases

Engineering Contradiction:
Improvedevice connectivityVSAvoidcable tray space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The invention performs preliminary cable termination and organization at the demarcation devices before cables enter the racks. By pre-organizing cables horizontally in the tray level, the system reduces the number of cables that need to be managed vertically in racks, improving space efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The demarcation devices act as intermediary elements between external cable sources and rack-mounted devices. These intermediaries consolidate and organize cable paths, reducing the total number of individual cable routes needed through the cable trays.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If patch panels are installed in racks to manage cable connections, then cable organization is improved, but rack space availability decreases

Engineering Contradiction:
Improvecable organizationVSAvoidrack space
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The invention extracts the cable organization function from rack-mounted patch panels and relocates it to demarcation devices in the cable trays. This removal frees up rack space while maintaining cable organization capabilities at the tray level.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention moves cable organization from the vertical rack dimension to the horizontal tray dimension. By organizing cables horizontally at the demarcation level before they enter racks vertically, the system achieves cable organization without consuming rack space.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
