Rack Cable Routing Device for Airflow and Clutter Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cable routing in information handling systems, where cables extend from the front to the rear of a rack, often results in cluttered and inefficient cabling, hindering airflow, occupying valuable space, and complicating device installation and maintenance.
Innovation Solution
A rack cable routing system with a front-to-rear cable routing device that defines protected cable conduits between computing devices, allowing cables to be routed from the front surface of one device to the rear surface of another within the rack, reducing clutter and improving airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are extended from the front to the rear of the rack using conventional routing methods, then connectivity between computing devices is achieved, but cable clutter increases and airflow is hindered
Solution Approach 1:
The cable routing path is segmented into multiple organized conduits rather than allowing cables to route freely. The cable management structure divides the routing space into distinct segments that guide cables through specific pathways from front to rear, reducing clutter while maintaining connectivity.
Solution Approach 2:
A cable management structure acts as an intermediary component between computing devices and cables. This structure provides organized conduits and pathways that mediate the routing process, preventing cables from directly obstructing airflow while ensuring proper connectivity.
2Ease of operation
If cables are routed through computing device housings to achieve front-to-rear connectivity, then cable routing is simplified, but valuable computing device housing space is occupied and airflow is reduced
Solution Approach 1:
The cable routing function is extracted from the computing device housings and consolidated into a dedicated cable management structure. This separates the cable routing function from the computing device housing, allowing the housing to be used exclusively for computing devices while cables route through the dedicated management structure.
Solution Approach 2:
A dedicated cable management structure serves as an intermediary that handles cable routing externally. This mediator component provides simplified routing pathways without requiring modification or occupation of computing device housing space, maintaining both ease of operation and housing availability.
3Reliability
If conventional cable routing methods are used, then basic connectivity is achieved, but device installation and maintenance become time-consuming and difficult
Solution Approach 1:
The cable management structure is pre-configured with organized conduits and pathways before computing devices are installed. This preliminary arrangement of cable routes eliminates the need for time-consuming cable routing during device installation and maintenance, as cables can be quickly connected through the pre-established pathways.
Solution Approach 2:
The cable routing system is segmented into organized, accessible sections that facilitate quick connection and disconnection. This segmentation allows technicians to access specific cable routes without disturbing other components, significantly reducing installation and maintenance time while ensuring reliable connectivity.

AI summary
A rack front-to-rear cable routing system includes a rack chassis having a first rack wall, a second rack wall opposite the first rack wall, a first rack entrance defined between the first and second rack walls, and a second rack entrance defined between the first and second rack walls and opposite the first rack entrance. A computing device housing is defined by the rack chassis. A rack front-to-rear cable routing device is located between the computing device housing and the first rack wall, and defines a protected cable conduit extending between the first and second rack entrances. The protected cable conduit houses a first cable connected to each of a first port on a first computing device in the computing device housing located adjacent the first rack entrance, and a second port on a second computing device in the computing device housing located adjacent the second rack entrance.
