Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the thermal solution is integrated into the server chassis, then cooling performance is improved, but device complexity and alignment difficulty increase
Solution Approach 1:
The thermal solution is segmented into a movable air duct portion and a stationary riser bracket portion. The air duct can be independently positioned and adjusted relative to the riser bracket, allowing the cooling function to be optimized without requiring complex integration into the chassis. This segmentation enables easy alignment and reduces device complexity.
Solution Approach 2:
The air duct is designed to be movable between open and closed positions relative to the riser bracket. This dynamic capability allows the system to adapt to different installation configurations and achieve optimal cooling alignment without requiring complex fixed integration into the chassis, thereby reducing alignment difficulty while maintaining cooling performance.
2Stability of the object's composition
If the air duct is fixed in position, then structural stability is improved, but ease of operation and component access worsen
Solution Approach 1:
The air duct is designed with movable capability between open and closed positions while maintaining structural stability when closed. This dynamic design allows easy access to electrical components when the air duct is opened, while preserving structural integrity and cooling function when closed, thus resolving the contradiction between stability and ease of operation.
Solution Approach 2:
The movable air duct acts as an intermediary element between the stationary riser bracket and the external environment. It provides controlled access to components while maintaining structural stability, serving as a mediator that reconciles the need for both fixed structure and operational accessibility.
3Temperature
If additional chassis components are used for cooling, then cooling effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The air duct is integrated with the riser bracket through movable coupling, combining the cooling function directly with the component mounting structure. This merging eliminates the need for separate additional chassis components, reducing device complexity and cost while maintaining cooling effectiveness through the integrated design.
Solution Approach 2:
The riser bracket assembly serves multiple functions: it mounts electrical components and provides integrated cooling through the coupled air duct. This multi-functionality eliminates the need for separate dedicated cooling components in the chassis, reducing the total number of components while maintaining effective cooling.
