Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional welded casing constructions are used, then manufacturing flexibility is maintained, but leakage occurs at weld points and temperature control is non-uniform
Solution Approach 1:
The patent merges multiple individual casing parts into a single integral component formed by 3D printing. This eliminates the weld joints between separate parts, thereby preventing leakage at connection points while maintaining manufacturing flexibility through additive manufacturing processes.
Solution Approach 2:
The patent replaces the mechanical welding process with a 3D printing process. Instead of joining separate parts through welding, the entire casing is manufactured as one piece using additive manufacturing, substituting the mechanical connection method with a direct formation method that eliminates joints entirely.
2Temperature
If conventional welded casing constructions are used, then manufacturing flexibility is maintained, but temperature distribution is non-uniform
Solution Approach 1:
The patent merges multiple individual casing parts into a single integral component formed by 3D printing. This eliminates the weld joints between separate parts, thereby preventing leakage at connection points while maintaining manufacturing flexibility through additive manufacturing processes.
Solution Approach 2:
The patent replaces the mechanical welding process with a 3D printing process. Instead of joining separate parts through welding, the entire casing is manufactured as one piece using additive manufacturing, substituting the mechanical connection method with a direct formation method that eliminates joints entirely.
3Strength
If conventional pumps are used, then structural simplicity is maintained, but casing deformation occurs under pipe forces and impeller conflicts with adjacent components
Solution Approach 1:
The patent merges the casing with integrated support structures formed as one piece through 3D printing. The support elements are built directly into the casing geometry, providing reinforcement against pipe forces and preventing impeller conflicts while maintaining overall structural simplicity.
Solution Approach 2:
The patent employs composite construction by integrating multiple functional elements (casing, support structures, mounting features) into a single complex geometry through 3D printing. This allows different regions of the component to have optimized properties for their specific functions while being manufactured as one integrated piece.
4Reliability
If conventional sealing covers with welding are used, then manufacturing flexibility is maintained, but leakage occurs at weld points and cooling/heating lines cannot be added
Solution Approach 1:
The patent merges the sealing cover with the casing into a single integral component formed by 3D printing. This eliminates the need for separate sealing covers with weld joints, providing leak-free sealing while enabling direct integration of cooling and heating lines into the unified structure.
Solution Approach 2:
The patent creates a universal sealing structure that combines sealing, structural support, and fluid passage functions in a single integrated component. The 3D printed design allows multi-functional elements to be built-in, enabling the addition of cooling and heating lines without requiring separate modifications to individual parts.
5Temperature
If conventional sealing covers with welding are used, then manufacturing flexibility is maintained, but uniform temperature control is difficult or impossible
Solution Approach 1:
The patent merges the sealing cover with the casing into a single integral component formed by 3D printing. This eliminates the need for separate sealing covers with weld joints, providing leak-free sealing while enabling direct integration of cooling and heating lines into the unified structure.
Solution Approach 2:
The patent replaces the mechanical welding process with a 3D printing process. Instead of joining separate parts through welding, the entire sealing cover and associated structures are manufactured as one piece using additive manufacturing, substituting the mechanical connection method with a direct formation method that eliminates joints entirely.
