Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a duct unit with multiple duct elements is used to direct cooling air from the blower unit to the heat sink, then the cooling efficiency and heat dissipation performance are improved, but the device complexity increases due to the need to assemble multiple duct elements together
Solution Approach 1:
The duct unit is divided into multiple duct elements (first duct element, second duct element, third duct element) that can be assembled together to form the complete cooling air channel. This segmentation allows for easier manufacturing, assembly, and maintenance while maintaining effective cooling air direction from the blower unit to the heat sink.
2Ease of operation
If the duct unit is designed with multiple separate duct elements, then the flexibility of configuration and ease of assembly are improved, but the potential for air loss at connection points increases
Solution Approach 1:
The multiple duct elements are designed to be connected together to form substantially continuous cooling air channels, merging the separate elements into a unified flow path. This reduces air loss at connection points while maintaining the assembly flexibility and ease of configuration that separate elements provide.
3Adaptability or versatility
If the heat sink is arranged at a distance from the blower unit outlet, then the layout flexibility and compact design are improved, but the cooling air delivery efficiency decreases
Solution Approach 1:
The duct unit extends in multiple spatial dimensions to bridge the distance between the blower unit outlet and the heat sink. By utilizing three-dimensional space effectively, the duct elements can reach components positioned at various locations and orientations, maintaining cooling efficiency while providing layout flexibility for compact hob designs.
4Adaptability or versatility
If the duct unit uses multiple separate duct elements, then the adaptability to different hob configurations is improved, but the manufacturing cost and assembly time increase
Solution Approach 1:
The duct system is segmented into multiple standardized duct elements that can be manufactured using efficient processes and then assembled. This segmentation enables modular manufacturing that can reduce overall production costs and assembly time compared to manufacturing a single complex duct structure, while maintaining high adaptability to different hob configurations.
