Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the flow passage area is increased to improve heat exchange efficiency, then the heat exchange efficiency is improved, but the plate body thickness must be increased which occupies more accommodating space
Solution Approach 1:
The patent applies dimensionality change by forming convex portions that protrude from the plate body surface, creating a three-dimensional flow passage structure. This allows the flow passage area to be increased without proportionally increasing the plate body thickness, as the additional flow area is achieved through lateral protrusion rather than uniform thickness increase throughout the entire plate.
Solution Approach 2:
The convex portions are strategically positioned at specific locations on the plate body where they protrude to form localized flow passages. This local quality approach increases the flow passage area only where needed for heat exchange, rather than uniformly increasing the entire plate structure, thereby optimizing the balance between heat exchange efficiency and space occupation.
2Area of moving object
If the plate body thickness is increased to provide more space for flow passage, then the flow passage area increases, but the structural strength and load-bearing capacity may be compromised
Solution Approach 1:
Instead of uniformly increasing plate thickness to create flow passage space, the patent uses convex portions that protrude in a lateral direction. This dimensional change allows flow passage area to be increased while maintaining the base plate thickness and its associated structural strength characteristics.
Solution Approach 2:
The plate body is segmented into a base plate and multiple convex portions that protrude from the surface. This segmentation allows the flow passage functionality to be distributed across multiple localized convex structures, each contributing to the total flow area while the base plate maintains its structural integrity and strength.
3Productivity
If convex portions are formed to increase flow passage area, then heat exchange efficiency is improved, but the manufacturing complexity increases
Solution Approach 1:
The convex portions are integrally formed with the base plate as a single unified structure, merging the flow passage functionality directly into the plate body design. This integration eliminates the need for separate components or complex assembly processes, reducing manufacturing complexity despite the enhanced three-dimensional geometry.
Solution Approach 2:
The convex portions serve multiple functions: they increase the flow passage area for heat exchange, provides structural support, and maintain the overall plate body integrity. This multi-functionality reduces the need for additional separate components, thereby simplifying the overall device complexity while achieving improved heat exchange efficiency.
