Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the propellant channel is integrated into the compressor housing, then the structure is more compact, but the vacuum deployment becomes more complex and less diagnosable
Solution Approach 1:
The propellant channel is separated from the compressor housing and placed in a separate housing. This segmentation allows the vacuum supply device to be independently assembled, tested, and diagnosed, reducing deployment complexity while maintaining structural compactness through separate mounting.
Solution Approach 2:
A separate housing acts as an intermediary component between the compressor housing and the vacuum supply device. This intermediary structure simplifies the integration process by providing dedicated mounting interfaces and allowing independent optimization of each subsystem.
2Ease of manufacture
If the propellant channel is integrated into the compressor housing, then manufacturing is simpler, but diagnostic capability is reduced
Solution Approach 1:
By separating the propellant channel into its own housing, the system enables independent diagnostics of the vacuum supply device without disassembling the entire compressor assembly. This segmentation maintains manufacturing simplicity through modular production while significantly improving diagnostic capability.
Solution Approach 2:
The separate housing design allows the vacuum supply device to be self-diagnosed and self-tested independently. Pressure sensors and other diagnostic tools can be applied to the separate housing without affecting the compressor housing, enabling self-service maintenance and troubleshooting.
3Ease of operation
If the propellant outlet connection is designed as a plug connection, then assembly is easier, but connection tightness may be compromised
Solution Approach 1:
The plug connection is combined with a sealing element (O-ring or similar) to merge the ease of plug-in assembly with the reliability of sealed connections. This hybrid approach maintains the simplicity of plug connections while ensuring adequate sealing performance through the integrated sealing component.
