Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If gas is supplied to the supply tank and vacuumed from the collection tank to maintain pressure balance, then pressure stability is improved, but pressure pulsations occur due to pump operations
Solution Approach 1:
A bypass path is introduced as an intermediary element connecting the supply tank and collection tank. This bypass allows gas to flow between tanks, serving as a mediator that absorbs pressure pulsations generated by the pumps. The bypass acts as a buffer that smooths out pressure fluctuations while maintaining the overall pressure balance required for stable liquid circulation.
2Productivity
If liquid circulation through the head is maintained at high flow rates, then discharge efficiency is improved, but bubble formation and overflow occur due to pressure fluctuations
Solution Approach 1:
The bypass path serves as a buffer that absorbs pressure pulsations, preventing them from propagating through the liquid circulation system. This intermediary gas path stabilizes the pressure conditions, allowing high flow rates through the head without causing bubble formation or overflow, thus maintaining both efficiency and reliability.
Solution Approach 2:
The system utilizes gas pressure control through the bypass path to regulate liquid flow stability. By controlling the gas pressure in the supply and collection tanks via the bypass, the system prevents pressure fluctuations that would otherwise cause liquid overflow or bubble formation, ensuring stable hydraulic operation at high flow rates.
3Measurement precision
If separate gas paths and pumps are used for supply and collection tanks, then pressure control precision is improved, but system complexity increases
Solution Approach 1:
While separate gas paths and pumps are used for precise pressure control in the supply and collection tanks, the bypass path merges these two systems. The bypass combines the gas flows from both tanks into a unified pressure balancing mechanism, reducing the effective complexity by creating an integrated pressure control system that maintains precision while simplifying the overall architecture.
