Solution Overview

Problem

Conventional IT server racks are bulky, costly, and difficult to assemble and transport due to their fixed size and heavy metallic construction, which limits optimization of size and scale, and does not meet the varying needs of information handling systems.

Innovation Solution

A modular, easily-assembled, lightweight, and structurally-rigid IT rack system composed of mini-rack modules with foldable corners and extendable trays made of lightweight materials, secured by banding components and corner pieces, allowing for customizable configuration and airflow management using a baffle with air flow directing apertures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional racks are constructed using heavy metallic components and fasteners, then structural strength and rigidity are improved, but weight and cost increase

Engineering Contradiction:
Improvestructural strengthVSAvoidrack weight
Core Design Contradiction:
StrengthVSWeight of moving object

Solution Approach 1:

The rack is divided into multiple rack units that can be individually assembled and stacked. Each rack unit contains standardized equipment mounting spaces, allowing the structure to be built only to the extent needed for specific applications, reducing unnecessary material usage while maintaining required strength

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rack employs composite construction combining metal components with alternative materials such as plastic or polymer elements. This reduces overall weight while maintaining structural integrity through strategic placement of high-strength materials only where mechanically critical

Inventive Principle:
Principle #40Composite materials

2Strength

If conventional racks are constructed using heavy metallic components and fasteners, then structural strength and rigidity are improved, but assembly difficulty and shipping cost increase

Engineering Contradiction:

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The modular design enables flexible sizing, reduced weight and cost, simplified assembly, and efficient airflow management, addressing the limitations of conventional racks by providing a scalable and cost-effective solution for supporting information handling systems.

Implementation Method 1

The baffle(s) includes air flow directing (AFD) apertures or holes with flanges that fold inwards towards the chassis of the IT rack. The baffle is designed to guide airflow through the IT rack using the AFD apertures and to provide a separation of the hot and cold aisles for IT gear that is placed within the IT rack.

AI summary

A method for designing and assembling a modular IT rack includes a manufacturer designing and constructing lightweight, modular corrugated cardboard modules/segments and corresponding banding and corner components that can be used to assemble the modular IT rack. A user/assembler of the modular IT rack assembles modular tray grouping and enclosure (MTGE) casing units using a first set of cardboard modules. The user constructs trays using a second set of cardboard modules. The user affixes cable support components to the sides of sub-groups of the constructed trays. The user encloses sub-groups of trays having the affixed cable support components within the assembled MTGE casing units to create MTGE blocks. The user vertically stacks the MTGE blocks having the tray sub-groups and the affixed cable support components enclosed within. The user aligns and secures the vertically stacked MTGE blocks in a fixed position using banding and corner components.
