Solution Overview

Problem

Existing data center rack systems with perpendicular orientations face challenges in space utilization, cooling efficiency, and ease of installation and maintenance, particularly in dimensionally constrained environments.

Innovation Solution

A data center rack system with angled rack stations and guidance tracks allows for flexible rack positioning, improved cooling airflow, and efficient installation and maintenance, utilizing aisle and station guidance tracks to orient racks at acute angles, enabling modular and secure rack configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If racks are arranged in perpendicular rows with tight fit to contain cooling air, then cooling efficiency is improved, but installation and maintenance difficulty increases

Engineering Contradiction:
Improvecooling efficiencyVSAvoidinstallation and maintenance ease
Core Design Contradiction:
Loss of energyVSEase of operation

Solution Approach 1:

The rack system employs movable rack units that can be dynamically positioned along guidance tracks rather than being fixed in perpendicular arrangements. This dynamic positioning capability allows racks to be easily installed, removed, and reconfigured while maintaining proper spacing for cooling airflow, thus resolving the contradiction between cooling efficiency and installation ease.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The rack system is divided into modular, independently movable rack units that can be segmented along the guidance tracks. Each rack unit can be independently installed or removed without affecting adjacent racks, enabling easy maintenance while preserving the tight-fit configuration needed for efficient cooling air containment.

Inventive Principle:
Principle #1Segmentation

2Loss of energy

If racks are fixed along the row to achieve tight fit, then cooling air containment is improved, but device complexity increases

Engineering Contradiction:
Improvecooling air containmentVSAvoidrack system complexity
Core Design Contradiction:
Loss of energyVSDevice complexity

Solution Approach 1:

The guidance tracks and movable rack units are designed to self-align and self-position along the tracks without requiring complex external fixation mechanisms. The racks automatically maintain proper spacing and orientation through the guidance track system, achieving tight fit for cooling containment while reducing overall system complexity by eliminating the need for complex fixed mounting structures.

Inventive Principle:
Principle #25Self-service

3Device complexity

If perpendicular rack orientation is used, then structural simplicity is maintained, but space utilization efficiency decreases

Engineering Contradiction:
Improvestructural simplicityVSAvoidspace utilization
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The rack system transitions from traditional two-dimensional perpendicular row arrangements to a three-dimensional configuration where racks are positioned at angled orientations along guidance tracks. This dimensional change enables more compact footprint and improved space utilization while maintaining structural simplicity through the use of straightforward guidance track geometry and movable rack units.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

This disclosure describes systems for arranging racks within a data center for a smaller and/or more flexible footprint, more efficient and/or resilient cooling, and/or easier installation. In some examples, this disclosure describes a data center rack system that includes an aisle and a plurality of rack stations adjacent to the aisle. The aisle includes an aisle guidance track defining an aisle axis. Each rack station of the plurality of rack stations includes a station guidance track defining a station axis. The station guidance track is configured to receive a rack from the aisle guidance track and position the rack in the respective rack station at a rack angle formed between the aisle axis and the station axis that is less than 90 degrees.
