Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If forced air cooling is used to dissipate heat from the conductive member, then heat dissipation efficiency is improved, but device complexity and cost increase due to requiring fans and mounting structures
Solution Approach 1:
The patent combines the heat dissipation function for the conductive member with the cabinet's existing heat dissipation system. The first heat dissipation air duct (for conductive member) is integrated with the second heat dissipation air duct (for cabinet), allowing a single fan to serve both cooling needs simultaneously, thereby eliminating the need for separate cooling components.
Solution Approach 2:
The cabinet's heat dissipation system is designed to perform multiple functions: it cools both the cabinet internal components and the conductive member externally. The shared air duct system and fan create a multi-functional cooling solution that reduces overall system complexity while maintaining effective heat dissipation for both elements.
2Temperature
If forced air cooling is used to dissipate heat from the conductive member, then heat dissipation efficiency is improved, but cost increases due to fans and structural members
Solution Approach 1:
The patent merges the cooling systems to eliminate redundant components. By integrating the conductive member's heat dissipation into the cabinet's existing forced air cooling infrastructure, the design removes the need for additional fans, mounting structures, and control systems, thereby significantly reducing manufacturing costs while maintaining effective heat dissipation.
Solution Approach 2:
The unified heat dissipation system provides multi-functionality, serving both the cabinet and conductive member with a single cooling infrastructure. This approach reduces the total bill of materials and simplifies manufacturing processes while achieving the required thermal management performance.
3Device complexity
If natural cooling is used for the conductive member, then device complexity is reduced, but heat dissipation efficiency is insufficient
Solution Approach 1:
The patent combines passive natural cooling (simple duct structure) with active forced convection (shared fan system). The conductive member's heat dissipation benefits from the cabinet's forced air cooling while utilizing a simplified duct structure, achieving effective heat removal without requiring a completely separate active cooling system.
