Protected Rack Cable Conduits for Front-to-Rear Airflow

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional cable routing in information handling systems, such as server devices and storage systems, often requires cables to extend between the front and rear of a rack, leading to issues like limited space, hindered airflow, and increased complexity, which can result in inefficient use of rack space and additional hardware requirements.

Innovation Solution

A rack front-to-rear cable routing device with protected conduits that are integrated into the rack, allowing cables to be routed efficiently from the front to the rear without obstructing airflow or occupying computing device housings, using magnetic, hook, or bracket mounting features to secure the device to the rack.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cables are extended between the front portion and rear portion of a rack using conventional routing methods, then connectivity between computing devices is achieved, but rack space is wasted, airflow is hindered, and cable management becomes complex

Engineering Contradiction:

Improvecable connectivityVSAvoidrack space utilization

Core Design Contradiction:

ReliabilityVSVolume of moving object

Solution Approach 1:

The patent extracts the cabling function from the computing device housings by introducing a separate cable routing device. This dedicated routing device contains protected cable conduits that extend from the front to rear of the rack, allowing cables to be routed through the routing device rather than through the computing device housings, thereby freeing up rack space and improving airflow.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The cable routing device acts as an intermediary component between the front and rear portions of the rack. It provides a dedicated pathway for cables to pass through, mediating the connection between computing devices at the front and rear of the rack without requiring cables to traverse through the computing device housings themselves.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If cables are routed through computing device housings to connect front and rear devices, then connectivity is established, but airflow through the rack is blocked and computing device housing space is lost

Engineering Contradiction:

Improvecable connectivityVSAvoidairflow obstruction

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If conventional cable routing methods are used, then basic connectivity is achieved, but cable tracing becomes difficult and cable bunching occurs

Engineering Contradiction:

Improvecable connectivityVSAvoidcable tracing and management

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent segments the cable routing function into dedicated protected conduits within the cable routing device. Each conduit provides a separate, organized pathway for cables, preventing cable bunching and making it easier to trace and manage individual cables. The conduits are structurally separated and protected, allowing for systematic cable organization rather than chaotic routing.

Inventive Principle:

Principle #1Segmentation

4Ease of operation

If additional racks are purchased to accommodate cable routing needs, then cable management space is increased, but hardware costs and rack density decrease

Engineering Contradiction:

Improvecable managementVSAvoidhardware requirements

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The cable routing device performs multiple functions within a single component: it provides protected cable conduits for front-to-rear routing, serves as a mounting structure for computing devices, and maintains rack structural integrity. This multi-functional design eliminates the need for additional racks or separate cable management hardware, reducing overall hardware requirements while improving cable management capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)
