Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If cooling liquid is used in vehicle cooling system, then heat absorption capability is improved, but phase change to gas occurs which reduces cooling performance
Solution Approach 1:
The cooling system is segmented into distinct functional zones within the coolant bottle: an expansion volume at the top for gas accumulation, a de-gasification zone with baffle plates for liquid-gas separation, and a coolant circulation channel at the bottom. This segmentation allows the system to accommodate phase changes while maintaining liquid coolant integrity for continuous cooling performance.
Solution Approach 2:
The baffle plates are strategically positioned to create a de-gasification zone that removes gas bubbles from the coolant before it returns to the cooling system. This preliminary action prevents gas accumulation in the cooling channels, ensuring consistent cooling performance before the coolant completes its circuit.
2Quantity of substance
If traditional coolant reservoir is used, then coolant storage is provided, but de-gasification function is not achieved
Solution Approach 1:
The baffle plates serve as an intermediary structure between the coolant storage volume and the coolant egress channel. They create a de-gasification zone that mediates the separation of gas and liquid phases, allowing gas to rise and accumulate in the expansion volume while liquid coolant flows through the designated channel, thus eliminating gas accumulation in the circulating coolant.
3Productivity
If coolant bottle with baffle plates and multiple ports is used, then de-gasification efficiency is improved, but device complexity increases
Solution Approach 1:
The coolant bottle integrates multiple functions into a single component: coolant storage, de-gasification, expansion accommodation, and temperature regulation. The baffle plates simultaneously create separation zones and provide structural support, while the integrated ports handle both coolant intake and egress. This merging reduces the need for separate de-gasification devices and simplifies the overall cooling system architecture.
Solution Approach 2:
The coolant bottle is designed as a multi-functional component that performs storage, de-gasification, expansion compensation, and temperature regulation functions. The baffle plates serve multiple purposes: separating gas and liquid phases, directing coolant flow, and providing structural integrity. This universality eliminates the need for additional dedicated de-gasification devices, maintaining simplicity while achieving high de-gasification efficiency.
4Temperature
If coolant is allowed to expand, then temperature regulation is improved, but volume increase requires larger reservoir
Solution Approach 1:
The coolant bottle employs local quality differentiation with an expanded upper section dedicated to gas accumulation and thermal expansion, while the lower section maintains a compact design for liquid coolant storage and circulation. This localized expansion allows the system to accommodate temperature-induced volume changes without requiring a uniformly large reservoir, optimizing both temperature regulation and space efficiency.
