Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a single large-capacity power source is used, then power output is sufficient, but reliability decreases when the power source fails
Solution Approach 1:
The power system is divided into multiple independent power sources (first power source and second power source) instead of using a single large-capacity power source. Each power source has a capacity of not more than 750 W, and they work together to provide the required total power output while maintaining system reliability through redundancy.
2Reliability
If multiple power sources are used, then reliability improves, but device complexity increases
Solution Approach 1:
Multiple power sources are merged into a single integrated power system with unified control. The controller manages both power sources together, and the power distribution unit consolidates their outputs, simplifying the overall system architecture while maintaining the reliability benefits of having multiple power sources.
Solution Approach 2:
The power system is designed with universal components that can handle multiple power sources. The power distribution unit and controller are designed to work with either one or multiple power sources, providing multi-functionality and reducing the need for separate specialized components for each power source configuration.
3Reliability
If multiple power sources are used, then reliability improves, but control difficulty increases
Solution Approach 1:
The controller incorporates feedback mechanisms to monitor the status of multiple power sources and automatically adjust their operation. The system detects the output status of each power source and dynamically controls their contribution to the total power output, simplifying the control process while maintaining optimal performance and reliability.

AI summary
Disclosed is a hybrid power system and an operation machinery. The hybrid power system includes an engine, a power distribution device, and a double-shaft extension motor. An input end of the power distribution device is connected to the output end of the engine, a first power output end of the power distribution device is connected to one end of the drive shaft, the input end is connected to the first power output end; a second power output end of the power distribution device is connected to one end of the double-shaft extension motor, and the second power output end is configured to selectively coupled with the input end or separated from the input end; another end of the double-shaft extension motor is configured to connect with the hydraulic power system. The power distribution device is provided with a power coupling state and a separation state; in the power coupling state, the first power output end and the second power output end form a power coupling connection, so that the engine is connected to the double-shaft extension motor; in the separation state, the input end and the second power output end are separated, so that the engine and the double-shaft extension motor are separated. Disclosed can conveniently realize on-demand distribution of the power of the hybrid power system by changing the working state of the power distribution device according to actual needs.
