Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a preset pouring location is used with fixed pumping duration, then automatic distribution can be achieved, but the system cannot dynamically adapt to construction demands and may pour wrong concrete grades
Solution Approach 1:
The patent implements dynamic adjustment of pumping speed based on real-time feedback. The control system continuously monitors actual pumping volume and adjusts the pumping speed dynamically to match the required distribution volume for different pouring locations and concrete grades, enabling the system to adapt to varying construction demands while maintaining automation.
Solution Approach 2:
The patent employs a feedback mechanism where the actual pumping volume is measured in real-time and compared with the target volume. The control system uses this feedback information to adjust pumping parameters, ensuring accurate distribution across different pouring locations with different concrete grade requirements, thereby resolving the contradiction between automation and adaptability.
2Productivity
If pumping volume is determined only by pumping time, then calculation is simple, but distribution volume accuracy is very large and cannot meet construction requirements
Solution Approach 1:
The patent replaces the simple time-based volume calculation with a feedback-controlled system that continuously measures actual pumping volume. The control system uses real-time feedback on pumping volume, piston stroke count, and concrete cylinder area to accurately determine when the target distribution volume is reached, significantly improving volume accuracy while maintaining operational efficiency.
Solution Approach 2:
The patent substitutes the mechanical/time-based volume determination method with an electronic control and measurement system. By using sensors, controllers, and digital calculation based on piston stroke counting and concrete cylinder dimensions, the system achieves precise volume control without relying solely on time-based estimation.
3Device complexity
If fixed pumping speed is used, then control is simple, but distribution volume cannot be accurately controlled and may exceed or fall short of requirements
Solution Approach 1:
The patent implements dynamic pumping speed control where the pumping speed is continuously adjusted based on real-time feedback. The control system monitors actual pumping progress and dynamically modifies pumping parameters to ensure the distribution volume precisely matches the target volume, resolving the contradiction between control simplicity and volume accuracy.
4Adaptability or versatility
If manual operation is required for boom and pumping, then flexibility is high, but operator workload is extremely high and labour intensity is high
Solution Approach 1:
The patent implements an automated control system that performs pumping operations autonomously. The system automatically controls pumping speed, monitors volume, and adjusts parameters without continuous manual intervention, significantly reducing operator workload while maintaining the flexibility to handle various construction scenarios through programmable control.

AI summary
The invention relates to the field of engineering machinery, and discloses a pumping control method and apparatus, a material distribution method and apparatus as well as a distribution device. The pumping control method includes: calculating an initialized pumping speed; controlling a distribution device to pump at the initialized pumping speed; and dynamically adjusting the pumping speed of the distribution device in real time according to a completed real-time distribution volume and real-time distribution time during the pumping of the distribution device until the real-time distribution volume is a desired distribution volume. Therefore, the accuracy of a final distribution volume is improved. The distribution method includes: controlling a distribution device to perform distribution at a to-be-distributed location in a preset distribution area; and after distribution at the to-be-distributed location is completed, determining a next to-be-distributed location in the preset distribution area and performing distribution at the next to-be-distributed location until distribution at each to-be-distributed location in the preset distribution area is completed. Therefore, automatic distribution is achieved.
