Solution Overview

Problem

In densely packed electronic component racks, accessing the rear or sides to attach heavier components for additional support is often impossible due to space constraints, making it difficult to mount and dismount components without access from both the front and rear.

Innovation Solution

A bracket and sleeve system where brackets are mounted to the rear of the rack through the front opening before the component is inserted, providing support along the component's depth without the need for additional fastening after installation, allowing components to be slid into place from the front with sleeves engaging the brackets for support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If racks are tightly packed side by side to increase space utilization, then the number of components per room increases, but access to the rear and sides of racks becomes difficult or impossible

Engineering Contradiction:
Improvenumber of components per roomVSAvoidaccess to rear and sides of rack
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The bracket is installed on the rack before the component is inserted. This preliminary action allows the bracket to be positioned and secured without requiring access to the rear of the rack, as the installer can reach through the front opening to attach the bracket. The component is then slid into place and engages with the pre-installed bracket, eliminating the need for rear access during component installation.

Inventive Principle:
Principle #10Preliminary action

2Strength

If components are made heavier to provide better support, then component stability improves, but the difficulty of mounting and dismounting components increases

Engineering Contradiction:
Improvecomponent support capabilityVSAvoidmounting and dismounting ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The bracket serves as an intermediary between the rack and the component. It provides structural support for heavy components while being installable through the front opening. The bracket's design allows it to bear the weight of heavy components and transfer that load to the rack, while its installation method (sliding through the front opening and engaging with the component) keeps the mounting process simple despite the component's weight.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Stability of the object's composition

If components are slid in from the front and bolted at both front and rear, then component support along the depth is improved, but the complexity of the mounting process increases due to required access from multiple directions

Engineering Contradiction:
Improvecomponent support along depthVSAvoidmounting process complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The bracket is installed on the rack before the component is inserted. This preliminary action allows the bracket to be positioned and secured without requiring access to the rear of the rack, as the installer can reach through the front opening to attach the bracket. The component is then slid into place and engages with the pre-installed bracket, eliminating the need for rear access during component installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention extracts the support function from the rear of the rack and relocates it to a bracket that can be installed through the front opening. This separation allows the support structure to be put in place without requiring rear access, simplifying the mounting process while maintaining support along the component's depth.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

The invention pertains to a system for mounting components to a rack comprising brackets that can be mounted to the rear of the rack through the opening in the front of rack before the component is inserted into the slot and mating sleeves running along the sides of the components. The brackets include arms that extend forwardly towards the front of the slot. After the brackets are attached, the component can be slid into the slot from the front with the sleeves sliding over and engaging the brackets. In this manner, the component can be slid into a slot on the rack with the brackets sliding into the sleeves, thereby providing support for the component along a substantial portion of the depth of the component without the need to bolt or otherwise fixedly attach the component to the bracket after the component is in the rack. Accordingly, a component can be installed in a rack without the need for any access except from the front of the rack.
