Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If large-sized heat dissipation fins are used to increase heat exchange area, then heat dissipation efficiency is improved, but manufacturing deformation increases and product structure becomes weaker
Solution Approach 1:
The heat dissipation assembly is divided into multiple smaller fin modules (first heat dissipation assembly and second heat dissipation assembly) connected by a splitter. Each module contains smaller fins that are less prone to deformation during manufacturing, while the combined structure provides sufficient total heat exchange area for effective heat dissipation.
2Reliability
If large-sized heat dissipation fins are used to increase heat exchange area, then heat dissipation efficiency is improved, but product structure strength decreases
Solution Approach 1:
The structure is segmented into multiple smaller fin modules connected by a splitter, creating a distributed structure that maintains overall strength while providing sufficient heat exchange area. The modular design allows for better structural support of each individual fin section.
Solution Approach 2:
Multiple smaller heat dissipation assemblies are merged together through the splitter to form a complete heat dissipation system. This combining approach maintains structural integrity through the splitter connection while avoiding the weakness associated with large single-piece fins.
3Reliability
If large-sized heat dissipation fins are used to increase heat exchange area, then heat dissipation efficiency is improved, but manufacturing yield decreases
Solution Approach 1:
The heat dissipation assembly is segmented into smaller modular units with smaller fins that are easier to manufacture with consistent quality. This segmentation reduces manufacturing complexity and improves yield while maintaining adequate heat exchange area through the combined structure.
