Solution Overview

Problem

Existing systems for mounting electronic devices on device racks often result in increased space requirements due to the dimensions of the mounting systems, which can lead to inefficiencies in rack utilization and cable management.

Innovation Solution

A bracket system for mounting electronic devices on device racks, featuring a bracket body with arms that are spaced apart to create an opening for cable routing, allowing for reduced overall dimensions of the mounting system and improved space utilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional mounting system with a cable routing body is used, then cables can be routed through the system, but the overall dimension of the mounting system in the longitudinal direction increases

Engineering Contradiction:
Improvecable routing capabilityVSAvoiddimension of mounting system in longitudinal direction
Core Design Contradiction:
Ease of operationVSLength of moving object

Solution Approach 1:

The patent combines the cable routing function with the mounting bracket structure itself. The bracket body includes arms that are spaced apart to define an opening, through which cables can be routed directly. This eliminates the need for a separate cable routing body, merging two functions (mounting and cable routing) into a single integrated component, thereby reducing the overall longitudinal dimension while maintaining cable routing capability.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If a cable routing body is added to the mounting system, then cable management is improved, but the space utilization on the device rack decreases

Engineering Contradiction:
Improvecable managementVSAvoidspace utilization on device rack
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The cable management function is merged into the bracket structure. The spaced-apart arms of the bracket define an opening that serves dual purposes: providing structural support for mounting the electronic device and enabling cable routing. This integration eliminates the need for additional space-consuming cable routing bodies, thereby improving space utilization on the device rack while maintaining effective cable management.

Inventive Principle:
Principle #5Merging (Combining)

3Length of moving object

If the bracket arms are positioned closer together, then the overall dimension is reduced, but cable routing capability is compromised

Engineering Contradiction:
Improvedimension of mounting system in longitudinal directionVSAvoidcable routing capability
Core Design Contradiction:
Length of moving objectVSEase of operation

Solution Approach 1:

The bracket arms are positioned at an optimal spacing that provides sufficient opening for cable routing without excessive separation. The design uses just enough space between the arms to accommodate cables passing through, avoiding both overly wide spacing (which would increase longitudinal dimension) and overly tight spacing (which would compromise cable routing). This partial action principle finds the optimal middle ground that satisfies both constraints.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

In A system for mounting an electronic device on a device rack is provided. The device rack is for supporting a plurality of the electronic devices spaced along the rack in a first direction of the system. The system comprises: the electronic device; and a bracket for mounting the electronic device in a device rack, the bracket comprising: a first coupler configured to couple the bracket to the electronic device; a second coupler configured to couple the bracket to the device rack; and a bracket body comprising: a first arm extending between the first coupler and the second coupler; and a second arm extending between the first coupler and the second coupler, wherein the first arm and second arm are spaced apart to define an opening through which one or more cables and/or fibres connected to the electronic device can extend.
