Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electrical connector is arranged with a radial plugging direction dependent on the counter fluid connector orientation, then the fluidic connection is established, but multiple pump versions are required to comply with different connector orientations
Solution Approach 1:
The pump housing is designed with a universal fluid connector configuration that can accommodate different counter fluid connector orientations. The fluid connector includes a pump inlet and pump outlet arranged such that the pump can be rotated around its axis to align with different mounting conditions, allowing a single pump version to serve multiple applications that previously required different versions.
Solution Approach 2:
The pump is designed to be rotatable around its rotation axis during installation to achieve the required rotational positioning of the electrical connector plug. This dynamic adjustment capability allows the pump to adapt to different counter electrical connector orientations without requiring multiple fixed versions, enabling the same pump design to be universally applied across various mounting conditions.
2Adaptability or versatility
If multiple pump versions are produced to meet different manufacturer requirements, then all connector orientation demands are satisfied, but production complexity and costs increase
Solution Approach 1:
By designing the fluid connector and pump housing with rotational symmetry and universal mounting capabilities, a single pump version can satisfy the diverse connector orientation requirements of different automotive manufacturers. This eliminates the need for producing multiple specialized pump versions, thereby simplifying production processes, reducing manufacturing complexity, and lowering production costs while maintaining full compliance with various manufacturer specifications.
3Reliability
If the pump is fixed in a specific rotational position, then the fluidic connection is optimized, but the electrical connector orientation cannot be adjusted for different manufacturers
Solution Approach 1:
The pump is designed to be rotatable around its rotation axis during the installation process, allowing the electrical connector plug to be positioned in the required rotational orientation for different manufacturers. Once positioned, the pump can be fixed while maintaining optimal fluidic connection through the universally designed fluid connector. This dynamic adjustment capability during installation resolves the contradiction between fixed fluidic connection optimization and electrical connector orientation flexibility.
