Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling surfaces are provided on both sides of the cooling device, then cooling performance is improved, but the number of exterior portion members increases and manufacturing cost increases
Solution Approach 1:
The patent merges the exterior portion and deformation suppressing portion into a single integrated component formed from one metal plate. This combining of functions into a single structure reduces the number of separate members needed while maintaining both cooling surfaces on front and back sides, thereby improving cooling performance without increasing device complexity
2Temperature
If cooling surfaces are provided on both sides of the cooling device, then cooling performance is improved, but manufacturing cost increases
Solution Approach 1:
The exterior portion and deformation suppressing portion are combined into a single metal member formed from one metal plate through press-forming and bending processes. This integration reduces the number of parts that need to be manufactured and assembled, thereby reducing manufacturing cost while maintaining dual-sided cooling surfaces for improved cooling performance
Solution Approach 2:
The single metal member serves multiple functions: it forms the exterior portion with dual cooling surfaces and simultaneously provides the deformation suppressing portion. This multi-functionality reduces the number of separate components needed, simplifying manufacturing and reducing cost while maintaining cooling performance
3Ease of manufacture
If the exterior portion is made from a single metal member with bent structures, then manufacturing cost is reduced, but deformation of the exterior portion may occur
Solution Approach 1:
The deformation suppressing portion is integrated into the single metal member structure, where bent structures are formed to create rigidifying portions. These bent structures act as internal supports that suppress deformation of the exterior portion while maintaining the single-member construction that reduces manufacturing cost
4Reliability
If edges of the exterior portion are welded over entire circumference, then sealing performance is improved, but manufacturing complexity increases
Solution Approach 1:
The deformation suppressing portion is integrated with the exterior portion in a single metal member, and the bent structures create natural sealing configurations. This integration simplifies the overall structure while maintaining effective sealing at the edges, reducing manufacturing complexity compared to separate component assemblies requiring extensive welding
