Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a plate heat exchange core body structure is used with electronic expansion valve and sensors in system duct line, then flow control accuracy is improved, but device complexity increases
Solution Approach 1:
The patent integrates the electronic expansion valve directly into the heat exchange core body structure, merging previously separate components (expansion valve, heat exchanger, sensors) into a unified assembly. This reduces the number of external connections and system duct lines required, thereby maintaining flow control accuracy while reducing overall system complexity
Solution Approach 2:
The heat exchange core body is designed to serve multiple functions: it acts as both the heat exchange medium and the housing for the electronic expansion valve and sensor components. This multi-functionality eliminates the need for separate system duct lines and reduces the number of parts, addressing the complexity issue while preserving measurement and control capabilities
2Measurement precision
If electronic expansion valve with sensors and control system is added, then flow control accuracy is improved, but the structure size increases
Solution Approach 1:
The electronic expansion valve and sensor components are nested within the heat exchange core body structure. The valve is positioned inside the core body's flow passages, and sensors are integrated into the same housing, allowing compact arrangement that reduces overall system volume while maintaining control functionality
3Productivity
If multiple stacked plates with complex orifices are used, then heat exchange efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The heat exchange core body is segmented into multiple stacked plates, each with specific orifice configurations. This segmentation allows for modular manufacturing where each plate can be produced separately and then assembled, reducing the overall manufacturing complexity compared to creating a single complex monolithic structure with equivalent heat exchange surfaces
