Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing liquid cooling systems for servers face challenges in effectively drawing leaking liquid from multiple branches due to the need for a single pump to handle both liquid and air, leading to inefficient suction and reduced operational time in case of leaks.
Innovation Solution
A leakage protection device with multiple liquid collecting components and suction pipelines, each equipped with a blocking component that prevents gas passage while allowing liquid to pass, ensuring efficient collection and removal of leaks without manual or electrical controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single pump is used to suction leaking liquid from multiple liquid collecting components through pipelines, then the device complexity is reduced, but the suction efficiency deteriorates when leakage occurs in only some branches
Solution Approach 1:
The patent divides the single suction system into multiple independent suction pipelines, each equipped with a blocking component. This segmentation allows each pipeline to operate independently, enabling the pump to efficiently suction liquid from branches where leakage occurs without being hindered by air in non-leaking branches, thus resolving the contradiction between device complexity and suction efficiency.
Solution Approach 2:
The blocking component acts as an intermediary element in each suction pipeline that automatically responds to the presence of liquid. When liquid is detected, the blocking component opens to allow suction; when only air is present, it remains closed. This intermediary mechanism enables the simple single-pump system to achieve high suction efficiency by selectively activating only the necessary branches.
2Device complexity
If the pump draws liquid and air simultaneously through all branches, then the system structure remains simple, but the allowable processing time is reduced
Solution Approach 1:
The blocking components are pre-installed in each suction pipeline in a closed state before leakage occurs. This preliminary action ensures that when leakage happens, only the branches with actual liquid leakage can be quickly activated for suction, immediately extending the allowable processing time without requiring complex real-time control systems.
Solution Approach 2:
The blocking components automatically respond to leakage conditions without external control, enabling the system to self-regulate which branches are active for suction. This self-service mechanism maintains simple system structure while significantly extending the time available to handle leakage by ensuring efficient liquid removal only from affected branches.
3Productivity
If blocking components are added to suction pipelines to prevent gas passage, then the suction efficiency is improved, but the device complexity increases
Solution Approach 1:
The blocking components are designed as simple, inexpensive elements that can be easily installed in each suction pipeline. Although they increase device complexity slightly, their low cost and simple structure make this complexity increase acceptable given the significant improvement in suction efficiency they provide by preventing gas passage and enabling selective liquid removal.
