Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an additional structure that provides a flow path is installed inside the heating apparatus, then heat transfer uniformity is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The flow path structure is merged with the heat-generating portion by forming recesses directly on its surface. The cooling fins and flow channels are integrated into a single component rather than being separate additions, thereby maintaining heat transfer uniformity while reducing device complexity and manufacturing cost.
Solution Approach 2:
The heat-generating portion serves multiple functions: it generates heat, provides structural support, and contains the integrated flow paths for heat transfer medium circulation. This multi-functionality eliminates the need for separate flow path structures, resolving the contradiction between reliability and device complexity.
2Reliability
If an additional structure that provides a flow path is installed inside the heating apparatus, then heat transfer uniformity is improved, but productivity decreases due to increased installation time and worker fatigue
Solution Approach 1:
By combining the flow path structure with the heat-generating portion into a single integrated component, the number of assembly steps is reduced. Workers no longer need to install separate flow path structures, thereby improving productivity while maintaining heat transfer uniformity through the integrated design.
Solution Approach 2:
The flow paths are pre-formed as recesses on the heat-generating portion during manufacturing, rather than requiring field installation. This preliminary action during production eliminates complex installation procedures, reducing worker fatigue and improving overall productivity.
3Reliability
If an additional structure that provides a flow path is installed inside the heating apparatus, then heat transfer uniformity is improved, but manufacturing cost increases due to additional members
Solution Approach 1:
The flow path structure is merged with the heat-generating portion, eliminating the need for separate flow path components. This reduction in the number of parts directly lowers manufacturing cost while maintaining heat transfer uniformity through the integrated design.
Solution Approach 2:
The heat-generating portion is designed to perform multiple functions including heat generation and flow path provision. This multi-functionality reduces the total number of components required, thereby lowering manufacturing cost while ensuring reliable heat transfer uniformity.
