Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the liquid cooling device is detachably mounted on the processor to ensure good heat dissipation effect, then the heat dissipation performance is improved, but the maintenance process becomes cumbersome requiring manual disassembly and reassembly
Solution Approach 1:
The liquid cooling device transitions from a static detachable mounting to a dynamic rotatable connection. The heat dissipation mechanism can rotate between a first position for heat dissipation and a second position for maintenance, eliminating the need for manual disassembly and reassembly while maintaining reliable heat dissipation performance.
2Reliability
If the liquid cooling device is detachably mounted on the processor, then the heat dissipation effect is ensured, but the maintenance time increases due to manual disassembly and reassembly requirements
Solution Approach 1:
The rotatable connection enables the heat dissipation mechanism to rotate to a maintenance position without disassembly, significantly reducing maintenance time. The dynamic connection maintains the liquid cooling loop integrity during rotation, ensuring continuous heat dissipation performance.
3Ease of operation
If the heat dissipation mechanism is made rotatable to facilitate maintenance, then the ease of operation is improved, but the device complexity increases due to rotary mechanisms and sealing requirements
Solution Approach 1:
A rotary sleeve serves as an intermediary component between the heat dissipation mechanism and the base mechanism. This intermediary element enables rotatable connection while maintaining liquid tight sealing, simplifying the overall structure compared to complex rotary joints. The rotary sleeve with waterproof part provides both rotational freedom and sealing functionality.
4Ease of operation
If rotary mechanisms with rotatable connections are used, then the ease of maintenance is improved, but the risk of liquid leakage increases during rotation
Solution Approach 1:
The rotary sleeve acts as an intermediary sealing element between the heat dissipation mechanism and base mechanism. It provides both rotational movement capability and liquid tight sealing through integrated waterproof parts, eliminating leakage risks during rotation.
Solution Approach 2:
Waterproof parts (flexible sealing elements) are integrated into the rotary sleeve structure, providing flexible sealing that maintains liquid integrity during rotation. These sealing components accommodate rotational movement while preventing liquid leakage.
