Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the rotary motor operates at rated speed to drive multiple hydraulic pumps, then the total power output is maximized, but the motor may become overloaded when multiple pumps operate at full power simultaneously
Solution Approach 1:
The patent applies dynamics by making the power distribution to hydraulic pumps variable rather than fixed. The adjuster dynamically redistributes the motor's power output among multiple hydraulic pumps based on operational needs, allowing the system to adapt power allocation in real-time while keeping the motor operating within its rated capacity and avoiding overload.
2Adaptability or versatility
If fixed power distribution is used among hydraulic pumps, then the system structure is simple, but the system cannot adapt to different operating modes and conditions
Solution Approach 1:
The adjuster introduces dynamic adaptability to the power distribution system. It enables variable power allocation among hydraulic pumps based on different operating modes and conditions, transforming a static system into a dynamic one that can respond to changing operational requirements without requiring complete system redesign.
Solution Approach 2:
The patent changes the power distribution parameter from a fixed value to a variable that can be adjusted according to operational needs. The adjuster modifies the power allocation parameters among hydraulic pumps, allowing the system to optimize performance for different drilling conditions while adding minimal structural complexity.
3Ease of operation
If individual power control for each hydraulic pump is implemented, then flexible power allocation is achieved, but the control system complexity increases
Solution Approach 1:
The adjuster serves as a universal control device that manages power distribution to multiple different hydraulic pumps through a single integrated mechanism. This multi-functional component simplifies the control system architecture by providing centralized power allocation control, reducing the need for separate complex control systems for each pump while maintaining flexible power distribution capabilities.

AI summary
The device has two hydraulic drives (11, 111), and a pump arrangement with pump units (10, 110), where the pump units comprise respective hydraulic pumps (12, 112) connected with the drives. A rotation motor (2) e.g. electric motor, has an output shaft (4) and drives the pumps, where output of the motor is distributed between the pumps. Two pump controllers control output of the pumps, and an adjusting device adjusts the distribution of the motor output between the pumps. The adjusting device has an operating element i.e. potentiometer, for adjusting distribution ratio of the motor output. An independent claim is also included for a method for operating a drilling device.
