Engineering Contradiction Analysis
1Object-affected harmful factors
If the volume in the connecting conduit system or buffer tank is increased, then the pressure fluctuations are reduced and comfort is improved, but the time duration between switching the booster pumps on and off increases
Solution Approach 1:
The pressure control parameters (upper and lower pressure limit values) are made dynamically adaptable rather than fixed. The control device automatically adjusts these parameters based on detected pressure values and system conditions, allowing the system to optimize the balance between pressure stability and pump operation frequency without manual intervention.
Solution Approach 2:
The control device performs self-adaptation by automatically adjusting the pressure control parameters based on detected pressure values. This self-learning mechanism eliminates the need for manual adaptation while optimizing the system's performance, reducing pressure fluctuations without excessively increasing the time between pump operations.
2Object-affected harmful factors
If the pressure difference between upper and lower limit values is reduced to minimize pressure fluctuations, then comfort is improved, but the number of switch-on procedures increases
Solution Approach 1:
The pressure control parameters are dynamically adjusted based on detected pressure values and system conditions. The control device learns from temporal pressure courses and adapts the pressure difference between upper and lower limit values to minimize fluctuations while avoiding excessive pump start-stop cycles.
Solution Approach 2:
The control device uses feedback from detected pressure values to continuously optimize the pressure control parameters. By monitoring the temporal course of pressure values, the system adjusts the pressure difference between limit values to achieve minimal fluctuations without causing an excessive number of switch-on procedures.
3Object-affected harmful factors
If manual adaptation of pressure control parameters is performed, then pressure fluctuations can be reduced, but the system requires manual intervention and does not automatically adapt to changing conditions
Solution Approach 1:
The control device automatically adapts the pressure control parameters by detecting pressure values and analyzing their temporal course. This self-learning mechanism replaces manual adaptation, allowing the system to automatically optimize pressure fluctuations while adapting to changing hydraulic conditions without human intervention.
Solution Approach 2:
The control device continuously monitors detected pressure values and uses this feedback to automatically adjust the pressure control parameters. This closed-loop approach enables the system to learn from operational data and autonomously optimize performance, eliminating the need for manual adaptation.

AI summary
A pressure boosting device increases pressure of a fluid flowing through a conduit (5) and includes a booster pump (2), a control device (12), controlling the booster pump (2), as well as a pressure sensor (8) arranged at the exit side of the booster pump (2) and connected to the control device. The control device (12) is configured to control the booster pump, in an operating region, in a start-stop operation, a switching off of the booster pump (2) when reaching an upper pressure limit value (P1) and a switching on of the booster pump (2) when reaching a lower pressure limit value (P2). The control device (12) is further configured in a start-stop operation to automatically adapt at least one pressure control parameter (P1, P2) of the control device (12) on the basis of the temporal course of at least one pressure value (P) detected by the pressure sensor.
