Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid-cooled servers face issues with water splashing during disconnection at the water inlet and outlet due to improper operation, posing a risk to nearby circuits and mining machines.
Innovation Solution
A connector system comprising a first connector body with a hollow cavity, a mesh baffle, and a ball body, where the mesh baffle has through-holes and an annular protrusion forming an annular through-hole, and an elastic retaining ring in the second connector, which prevents fluid from splashing when disconnected by forming a closed passage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple connector structure is used, then ease of operation is improved, but water splashing occurs when disconnected
Solution Approach 1:
The patent introduces a ball body as an intermediary element that automatically responds to pressure changes. When the connector is disconnected, the ball body moves to block the through-hole, preventing water splashing without requiring manual intervention or complex valve mechanisms, thus maintaining ease of operation while eliminating the harmful splashing effect.
Solution Approach 2:
The ball body mechanism operates autonomously based on pressure differential. During normal operation, water pressure keeps the ball body away from the through-hole allowing flow. Upon disconnection, pressure drops and the ball body automatically moves to seal the opening, providing self-protection without external control systems.
2Reliability
If a valve is added to prevent water splashing, then safety is improved, but device complexity increases
Solution Approach 1:
The patent uses a simple ball body instead of a complex valve mechanism. The ball body is a basic spherical object that can be easily manufactured and replaced if needed, providing reliable splash prevention through its simple geometric shape and automatic positioning rather than through complex mechanical or electronic valve systems.
Solution Approach 2:
The ball body's position changes in response to pressure parameter variations. Under operating pressure, the ball remains positioned away from the through-hole. When pressure drops upon disconnection, the ball moves to seal the opening. This automatic response to parameter change eliminates the need for complex control systems.
3Ease of repair
If the connector is disconnected for maintenance, then ease of repair is improved, but water splashing risk increases
Solution Approach 1:
The patent converts the potentially harmful effect of disconnection (water splashing) into a beneficial automatic sealing action. The pressure differential that occurs during disconnection naturally drives the ball body to seal the through-hole, transforming the harmful splashing scenario into a self-sealing protective mechanism that safeguards surrounding equipment during maintenance operations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Effectively prevents water from splashing back at the water inlet and outlet when the connector is disconnected, ensuring safety and preventing damage to surrounding equipment.
Implementation Method 1
when fluid enters from an end close to the mesh baffle, the ball body blocks the annular through-hole under the action of a fluid pressure in a pipe wall of the first connector body
