Solution Overview

Problem

There is a risk of coolant leakage when a server is installed in a rack, and if the coolant circuit is not cut in time, a large amount of coolant can enter the server, causing damage.

Innovation Solution

A joint module is introduced that includes a base, moving pieces, and a drive component, which allows the plug connectors to disconnect from the plugs when coolant leakage is detected, thereby cutting the coolant circuit and preventing further coolant entry into the server.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the coolant circuit remains connected to provide continuous cooling, then the server cooling function is maintained, but coolant leakage damage occurs when leakage happens

Engineering Contradiction:
Improveserver protection from coolant damageVSAvoidcoolant leakage damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The joint module is pre-installed on the server backend, and the disconnection mechanism is pre-configured. When leakage is detected, the system can immediately execute the disconnection action without delay, as all components are already in position and ready for rapid response

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The joint module acts as an intermediary component between the rack plug and the server plug connector. It includes a moving piece with a disconnection mechanism that can be driven to separate the plug connector from the plug, thereby mediating the connection state and enabling controlled disconnection when leakage occurs

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If the coolant circuit is disconnected immediately upon leakage detection, then coolant damage is prevented, but the cooling function is interrupted

Engineering Contradiction:
Improvecoolant leakage damageVSAvoidserver cooling
Core Design Contradiction:
Object-affected harmful factorsVSTemperature

Solution Approach 1:

The joint module employs a dynamic disconnection mechanism where the moving piece can transition between connected and disconnected states. This dynamic capability allows the system to adapt its connection state based on real-time conditions - maintaining connection during normal operation for cooling, and disconnecting when leakage is detected to prevent damage

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses leakage detection feedback to control the disconnection mechanism. When coolant leakage is detected, the feedback signal triggers the drive component to move the moving piece, which in turn moves the plug connector to disconnect from the plug, thereby cutting off the coolant supply in response to the leakage condition

Inventive Principle:
Principle #23Feedback

3Device complexity

If a traditional fixed connection is used between rack and server, then the structure is simple, but the system cannot respond to coolant leakage

Engineering Contradiction:
Improvejoint module structureVSAvoidcoolant leakage response
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The joint module segments the connection system into distinct functional components: a fixed rack plug, a movable joint module with moving piece, and a server plug connector. This segmentation allows the middle section to move independently, enabling disconnection functionality while keeping the overall structure modular and manageable

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The joint module serves as an intermediary component between the rack plug and the server plug connector. It includes a moving piece with a disconnection mechanism that can be driven to separate the plug connector from the plug, thereby mediating the connection state and enabling controlled disconnection when leakage occurs

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A joint module for cutting coolant circuit in a server comprises a base, a first moving piece, a second moving piece, a drive component, and a plug connector located on the first moving piece. The first moving piece is movable in a first direction between a first position and a second position. The second moving piece is movable in a second direction between a third position and a fourth position. The drive component moves the second moving piece. When the second moving piece is on the third position, the first moving piece is on the first position and the plug connector is connected to a plug. When the second moving piece is on the fourth position, the first moving piece is on the second position and the plug connector is disconnected with the plug. A server and a computing system with the joint module are also disclosed.
