Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a heat insulating member is used to form an air layer, then heat insulating property is improved, but the number of components increases
Solution Approach 1:
The heat insulating function is merged into the duct body structure itself by forming an air layer between the upstream and downstream ducts. The downstream duct is positioned inside the upstream duct, creating an integrated heat insulating structure that eliminates the need for separate heat insulating members while maintaining effective thermal insulation.
Solution Approach 2:
An air layer is introduced as an intermediary substance between the upstream and downstream ducts to provide heat insulation. This air layer acts as a thermal barrier without requiring additional solid insulating materials, thereby reducing component count while achieving the desired heat insulating effect.
2Temperature
If separate heat insulating members are used, then heat insulation is achieved, but manufacturing complexity and assembly difficulty increase
Solution Approach 1:
The heat insulating structure is merged with the duct body as an integrated design. The upstream and downstream ducts are configured to form an air layer between them, eliminating the need for separate manufacturing and assembly of heat insulating members. This integration simplifies both manufacturing processes and assembly operations.
3Ease of operation
If ducts are connected without a fitting structure, then assembly is simple, but connection accuracy and reliability decrease
Solution Approach 1:
The duct connection is segmented into distinct fitting structures: a convex portion on the downstream duct and a corresponding concave portion on the upstream duct. This segmentation allows for precise positioning and secure connection while maintaining ease of assembly. The fitting structures guide the ducts into proper alignment during assembly.
Solution Approach 2:
The downstream duct is nested inside the upstream duct in the overlapping region, with the convex portion of the downstream duct fitting into the concave portion of the upstream duct. This nested configuration with integrated fitting structures ensures accurate connection and proper positioning while simplifying the assembly process through self-alignment.
