Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cooling distribution modules are used to provide redundancy and fault tolerance, then system reliability is improved, but device complexity increases
Solution Approach 1:
The cooling system is divided into multiple independent cooling distribution modules, each capable of operating autonomously. This segmentation allows the system to maintain functionality even when individual modules fail, thereby improving reliability while keeping each module's complexity manageable.
Solution Approach 2:
The system dynamically adjusts the operational status of cooling distribution modules based on real-time conditions. Modules can transition between active and standby states, and flow rates are dynamically controlled based on the number of active modules and thermal conditions, optimizing system performance and reliability.
2Ease of repair
If cooling distribution modules are isolated and hot-swappable, then ease of repair is improved, but device complexity increases
Solution Approach 1:
Each cooling distribution module is designed as an isolated, self-contained unit with standardized connection interfaces. This segmentation enables modules to be independently removed and replaced without affecting other parts of the system, significantly improving ease of repair.
Solution Approach 2:
The system is pre-configured with multiple identical cooling distribution modules that can be quickly swapped in and out. Replacement modules are prepared in advance and can be installed without specialized tools or procedures, reducing repair time and complexity.
3Use of energy by moving object
If circulation pumps operate at less than full capacity with multiple modules, then energy efficiency is improved, but cooling capacity may be reduced
Solution Approach 1:
The circulation pumps dynamically adjust their flow rates based on the number of active cooling modules and the thermal load conditions. When multiple modules are operating, each pump can run at reduced capacity, improving energy efficiency. The system maintains adequate cooling capacity through the combined output of multiple pumps and modules.
Solution Approach 2:
Multiple cooling distribution modules work together in parallel, combining their cooling capacities. This allows individual pumps to operate at lower, more efficient capacities while the aggregate cooling capacity of the system remains sufficient to handle the thermal load.
