Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional reservoirs are added to the pump system to enable vacuum pumping and liquid delivery, then the system can perform both vacuum and liquid functions, but the space efficiency deteriorates and device complexity increases
Solution Approach 1:
The patent combines the vacuum pump unit and liquid pump unit into a single integrated assembly where the liquid delivery unit is positioned directly behind the vacuum pump unit. The liquid delivery unit utilizes the vacuum pump's housing and drive mechanism, eliminating the need for separate reservoirs and reducing overall system complexity while maintaining both vacuum and liquid delivery functionalities.
Solution Approach 2:
The vacuum pump unit is designed to serve dual purposes: it functions as a vacuum pump for gas evacuation and simultaneously provides the housing, drive mechanism, and structural support for the liquid delivery unit. This multi-functional design reduces the number of components needed while achieving both vacuum and liquid delivery capabilities.
