Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional liquid cooling devices suffer from inadequate coolant levels due to vaporization, leading to manual supplementation challenges, which can result in insufficient coolant and device damage from air generation.
Innovation Solution
A water supply structure with a pressure control member, comprising a piston and elastic part, is integrated into the liquid cooling device, pump, and cooling module to automatically supplement coolant until hydraulic pressure equilibrium is achieved, ensuring timely replenishment and preventing air generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual observation and supplementation of coolant is used, then the device structure remains simple, but the coolant cannot be supplemented timely and the user may forget to supplement water causing device damage
Solution Approach 1:
The system enables self-service through the pressure control member (piston and elastic part) that automatically detects coolant levels and supplements coolant without user intervention. The elastic part expands when coolant is insufficient, pushing the piston to open the valve and allow coolant flow, then automatically closes when pressure equalizes, creating a self-regulating system.
Solution Approach 2:
The feedback mechanism is implemented through the pressure differential between the liquid reservoir and cooling module. When coolant level drops, pressure changes trigger the elastic part to expand, which signals the piston to move and open the valve. When coolant is sufficient, pressure equalizes and the valve closes automatically, providing continuous feedback-based control.
2Ease of operation
If the liquid reservoir is opened manually to supplement coolant, then no additional components are needed, but the user experiences inconvenience and may forget to supplement water timely
Solution Approach 1:
The water supply structure performs self-service by automatically monitoring coolant levels through pressure changes and supplementing coolant through the piston-valve mechanism. The elastic part acts as a sensor that expands when pressure drops (indicating low coolant), triggering automatic supplementation without requiring user observation or manual intervention.
Solution Approach 2:
The manual mechanical operation of opening the reservoir and adding water is replaced by an automated mechanical system involving the elastic part, piston, and valve. This substitution transforms a manual task into an automatic mechanical response driven by pressure differentials, improving both ease of operation and reliability.
3Productivity
If insufficient coolant operates continuously, then the device continues to function, but air is generated and side effects occur reducing device lifetime
Solution Approach 1:
The system takes preliminary action by continuously maintaining adequate coolant levels through automatic supplementation. The pressure control mechanism proactively detects when coolant is insufficient and replenishes it before air can be generated, preventing harmful conditions rather than reacting to them after they occur.
Solution Approach 2:
The feedback loop continuously monitors pressure conditions that indicate coolant levels. When pressure drops signaling low coolant, the system automatically responds by opening the valve to supplement coolant, ensuring continuous operation with sufficient coolant and preventing air generation that would reduce device lifetime.

Implementation Method 1
The pressure control member comprises a piston and an elastic part controlling the piston to move inside the chamber. The elastic part pushes against the piston to move inside the chamber such that the coolant is injected into the liquid cooling device until hydraulic pressure equilibrium is achieved.
Implementation Method 2
The elastic part pushes against the piston to move inside the chamber such that the coolant is injected into the liquid cooling device until hydraulic pressure equilibrium is achieved.
