Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a horizontal multi-row deployment mode is adopted to improve density, then the equipment arrangement density is improved, but the center of gravity becomes unstable which increases transportation risks
Solution Approach 1:
The patent employs asymmetric arrangement of equipment within the container, positioning heavier components at the bottom and lighter components at the top, while arranging computing equipment cabinets in a multi-row configuration that maintains balanced weight distribution. This asymmetric yet balanced layout achieves high density (up to 80KW per cabinet) while ensuring stable center of gravity for safe transportation.
2Ease of operation
If a single-row deployment mode is adopted for maintenance convenience, then the ease of maintenance is improved, but the equipment arrangement density and per unit volume power density are low
Solution Approach 1:
The patent divides the container into multiple independent rows of computing equipment cabinets, with each row being accessible from both sides. This segmentation allows maintenance personnel to access any cabinet through side aisles, maintaining ease of maintenance while achieving high equipment arrangement density through multi-row configuration. The power distribution cabinets are also segmented and positioned at accessible locations serving multiple rows.
3Temperature
If liquid cooling is used to improve heat dissipation efficiency, then the heat dissipation capacity is improved, but the device complexity increases
Solution Approach 1:
The patent implements a liquid cooling system using water circulation through cold plates mounted on computing equipment. The system includes water pumps, heat exchangers, and circulation pipes that dissipate heat efficiently (achieving 80KW per cabinet capacity). While the hydraulic system adds some complexity, it provides superior heat dissipation compared to air cooling, and the modular design keeps the complexity manageable through standardized components.
