Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If hydro-mechanical damping measures are used to reduce vibrations, then stability improves, but device complexity increases
Solution Approach 1:
The patent replaces hydro-mechanical damping measures with an electronic control system that uses sensors to detect vibrations and actuators to counteract them. This substitution of mechanical damping components with an electronic control system reduces device complexity while maintaining stability improvement.
Solution Approach 2:
The patent introduces an electronic control system as an intermediary between the hydro machine and the hydraulic consumers. This intermediary uses sensors to detect system state and actuators to adjust parameters, thereby reducing vibrations and improving stability without requiring complex hydro-mechanical damping components.
2Ease of operation
If additional damping components are added to reduce vibrations, then movement quality improves, but device complexity increases
Solution Approach 1:
The patent replaces mechanical damping components with an electronic control system that actively manages vibrations through sensor feedback and actuator response. This substitution improves movement quality while avoiding the addition of complex mechanical damping components.
Solution Approach 2:
The electronic control system continuously monitors system parameters through sensors and automatically adjusts actuator positions to counteract vibrations. This self-regulating mechanism improves movement quality without requiring external damping components or manual intervention.
3Adaptability or versatility
If electronic control is used to master hydro machine dynamics, then dynamic characteristic adjustability improves, but device complexity increases
Solution Approach 1:
The patent implements an electronic control system that dynamically adjusts hydro machine parameters based on real-time sensor feedback. This dynamic control approach enables adaptable dynamic characteristics while using a relatively simple electronic architecture compared to complex hydro-mechanical adjustment mechanisms.
Solution Approach 2:
The electronic control system changes operational parameters such as delivery volume and outlet pressure based on detected system conditions and desired dynamic characteristics. This parameter-based control provides adjustability without requiring complex mechanical adjustment mechanisms.

AI summary
A hydraulic pressurizing medium supply assembly having a hydro machine for supplying pressurizing medium of at least one hydraulic consumer, includes a hydraulic control block for controlling the at least one consumer, a first control module, and a second control module. The control block, by way of the first control module, is able to be controlled by at least one actuating signal. A data interface is included between the control modules. The first control module, by way of the data interface, as a further actuating signal transfers to the second control module as input variable/variables a nominal outlet pressure for the hydro machine and/or a nominal delivery volume for the hydro machine. The second control module by way of the nominal outlet pressure and/or by way of the nominal delivery volume controls an adjusting mechanism of the hydro machine by way of a valve actuating signal.
