Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If liquid cooling blocks are used for direct cooling of processing components, then heat dissipation efficiency is improved, but risk of liquid leakage and electrical shortage increases
Solution Approach 1:
The patent implements leakage detection sensors and automated valve shutdown systems before actual leakage occurs. The system continuously monitors for leakage conditions and preemptively shuts off cooling liquid flow when leakage is detected, preventing electrical shortages before they can occur.
Solution Approach 2:
The patent introduces intermediate detection and control components between the cooling liquid source and the processing components. Leakage detection sensors act as intermediaries to monitor liquid flow, and automated valves serve as intermediaries to control liquid flow, creating a safety buffer that prevents direct contact between leaking liquid and electrical components.
2Reliability
If leakage detection devices and automated valve systems are added, then reliability against liquid leakage is improved, but device complexity increases
Solution Approach 1:
The patent implements a self-service automated response system where the leakage detection sensors automatically trigger valve shutdown without requiring external intervention. When leakage is detected, the system self-corrects by closing the valves, eliminating the need for manual monitoring or complex control systems.
Solution Approach 2:
The patent combines multiple functions into integrated components. The leakage detection sensors are integrated with the existing cooling system infrastructure, and the automated valves are combined with the flow control system, reducing the need for separate standalone monitoring and control systems.
3Temperature
If control valves are used to regulate cooling liquid flow, then temperature control precision is improved, but device complexity and maintenance needs increase
Solution Approach 1:
The patent implements feedback control where temperature sensors continuously monitor the thermal state of processing components and automatically adjust valve positions to maintain optimal temperature. This closed-loop control system simplifies temperature management by using automatic feedback rather than complex manual control mechanisms.
Solution Approach 2:
The patent controls temperature by changing flow rate parameters through automated valves rather than changing physical configurations. By adjusting the flow rate of cooling liquid, the system achieves precise temperature control through parameter adjustment rather than mechanical reconfiguration.
