Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single supply line is used to feed liquid gas to the cooling bath, then the device structure is simple, but at high flow rates rapid evaporation and pressure fluctuations occur, affecting temperature control precision
Solution Approach 1:
The single supply line is divided into multiple parallel supply lines (first, second, third supply lines). Each line is equipped with its own shut-off valve and level detection mechanism, allowing independent control. This segmentation enables gradual adjustment of liquid gas inflow to match evaporation rates, preventing pressure fluctuations and maintaining temperature control precision even at high flow rates.
2Measurement precision
If multiple supply lines with level detection mechanisms are used, then temperature control precision is improved, but the device complexity increases
Solution Approach 1:
Each supply line is equipped with a level detection mechanism that automatically activates the corresponding shut-off valve when the liquid gas level drops to a predetermined level. This self-service mechanism eliminates the need for complex external control systems, as the system automatically regulates its own liquid gas supply based on real-time level monitoring, thereby improving temperature control precision without proportionally increasing device complexity.
3Productivity
If the inflow of liquid gas is increased to maintain cooling bath level at high flow rates, then the cooling capacity is improved, but pressure fluctuations increase, affecting process stability
Solution Approach 1:
The system dynamically adjusts the inflow of liquid gas by selectively activating supply lines based on real-time level detection. As the cooling bath level drops, additional supply lines are gradually opened to match the evaporation rate caused by high flow rates through the heat exchanger. This dynamic adjustment maintains cooling capacity while preventing pressure fluctuations, thereby ensuring process stability.

AI summary
The device (1) has supply lines (12, 13, 14, 15) equipped with lock fittings (16-19) and fluidically connected with a supply container (6). The supply lines are led into an insulated container (3) for supply of a cooling bath (10). The lock fittings are operatively connected with a device for detecting a filling level of the cooling bath such that the lock fittings opens and/or closes the supply lines at a preset border filling level. A different border filling level is predetermined for the supply lines. Float valves are provided as the lock fittings.
