Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a plug connector is used to connect the server and rack for coolant flow, then coolant can be supplied to cool the server, but coolant may leak from the connection causing damage to the server
Solution Approach 1:
A sensor is installed in the plug connector to detect coolant leakage in advance. When leakage is detected, the switch changes state to trigger the folding mechanism, which proactively disconnects the plug connector from the rack plug, preventing further coolant ingress and damage to the server
Solution Approach 2:
The folding mechanism acts as an intermediary between the sensor detection and the disconnection action. It translates the sensor's electrical signal into mechanical motion, folding the plug connector away from the rack plug to sever the coolant circuit and stop leakage
2Temperature
If the plug connector remains connected for continuous coolant supply, then cooling is maintained, but leakage risk increases causing potential server damage
Solution Approach 1:
The sensor continuously monitors the connection for coolant leakage and provides feedback to the switch. When leakage is detected, the switch changes state to activate the folding mechanism, which disconnects the connector. This feedback loop enables continuous cooling while automatically responding to leakage conditions to prevent damage
3Reliability
If a folding mechanism with electromagnet switch is added to detect and disconnect upon leakage, then server protection is improved, but device complexity increases
Solution Approach 1:
The system performs self-protection by using the sensor to automatically detect leakage and trigger the folding mechanism without human intervention. The electromagnet switch and folding mechanism work together to autonomously disconnect the plug connector, protecting the server from coolant damage without requiring external control
Solution Approach 2:
The manual or complex mechanical disconnection system is replaced with an electromagnet-based actuation mechanism. The electromagnet switch converts electrical signals from the sensor into mechanical folding motion, simplifying the control system while enabling reliable automatic disconnection upon leakage detection

AI summary
A joint for cutting coolant circuit in a server comprises a first shell, a second shell, and a folding mechanism. The first shell has a tunnel and a seal ring in the tunnel. The second shell has a first tube section and a second tube section. The folding mechanism can move the second shell. The first tube section and the second tube section are movably inserted in the tunnel, an outer diameter of the first tube section is larger than an outer diameter of the second tube section, when the second shell is on a first position, the seal ring surrounds the first tube section and is compressed by the first tube section, when the second shell is on a second position, the seal ring surrounds the second tube section and is uncompressed. A server and a computing system with the joint are also disclosed.
