Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the switch is mounted in the liquid-containing tank body without dedicated cable-passing devices, then the layout flexibility is improved, but the wiring complexity and installation difficulty increase

Engineering Contradiction:
Improvelayout flexibilityVSAvoidwiring complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable-passing device assembly is segmented into multiple functional components: cable-passing holes positioned at different locations (front, rear, sides), cable fixing structures at specific positions, and supporting plates. This segmentation allows cables to be routed through dedicated pathways rather than requiring complex ad-hoc wiring solutions, thereby reducing wiring complexity while maintaining layout flexibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cable-passing device assembly acts as an intermediary structure between the switch mounting position and the rest of the cabinet system. It provides standardized cable routing pathways and fixing mechanisms that mediate the connection between the switch and external components, simplifying the overall wiring architecture while enabling flexible switch placement within the tank body.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If temporary non-standardized layout is used for switch installation, then the installation adaptability is improved, but the maintenance difficulty and operational reliability worsen

Engineering Contradiction:
Improveinstallation adaptabilityVSAvoidoperational reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The cable-passing device assembly is pre-configured with cable-passing holes, cable fixing structures, and supporting plates positioned in advance during cabinet manufacturing. This preliminary action ensures that when the switch is installed, the cable routing pathways and fixing mechanisms are already in place, eliminating the need for temporary non-standardized layouts and ensuring consistent, reliable installation that facilitates easy maintenance and operational reliability.

Inventive Principle:
Principle #10Preliminary action

3Device complexity

If the cable-passing device assembly is simplified, then the device complexity is reduced, but the cable fixing reliability and wiring neatness worsen

Engineering Contradiction:
Improvedevice complexityVSAvoidcable fixing reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The cable-passing device assembly merges multiple functions into an integrated structure: cable-passing holes provide routing pathways, cable fixing structures provide secure anchoring points, and supporting plates provide mechanical support. This merging of functions into a single unified assembly achieves reliable cable fixing and neat wiring without requiring multiple separate components, thereby reducing overall device complexity while maintaining high reliability.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present application discloses an immersion liquid-cooling cabinet comprising: a cabinet body; a liquid containing tank body mounted in the cabinet body for containing a cooling liquid; at least one server mounting position provided within the liquid containing tank body; at least one switch mounting position vertically provided around the liquid containing tank body; a cable-passing device assembly fixedly mounted on top of the switch mounting position, within which a cable of a switch mounted at the corresponding switch mounting position is routed. The structure of the immersion liquid-cooling cabinet gives full consideration to the layout, installation and wiring of the switch, thereby improving the rationality of the overall structure; and an integrated installation technology for the switch and the server is adopted, so that the immersion liquid-cooling cabinet is more compact in space utilization and more neat and beautiful in appearance.
