Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a diesel engine is used to drive the transmission and fracturing plunger pump, then the system can provide sufficient power, but the volume and weight increase significantly
Solution Approach 1:
The patent combines the generator and rectifier into an integrated power supply device, merging multiple functions (power generation, voltage rectification) into a single compact unit. This reduces the overall system volume and weight while maintaining sufficient power output for fracturing operations.
Solution Approach 2:
The patent extracts and eliminates the diesel engine and transmission components from the system by using an electric drive system instead. This removes the large-volume internal combustion engine while providing power through a more compact generator-rectifier integration.
2Duration of action of moving object
If a diesel engine is used to drive the fracturing plunger pump, then the system can operate continuously, but environmental pollution and noise increase
Solution Approach 1:
The patent replaces the mechanical diesel engine system with an electrical power system. The generator produces electricity that is rectified and used to drive the fracturing pump, eliminating combustion-related pollution and noise while maintaining continuous operation capability.
3Power
If a diesel engine with transmission is used, then the system can deliver high power, but the cost and maintenance requirements increase
Solution Approach 1:
The patent merges the generator and rectifier into a single integrated power supply device, reducing the number of separate components and simplifying the overall system. This integration maintains high power delivery capability while reducing device complexity and maintenance requirements.
4Reliability
If multiple black-start devices are used for multiple generators, then each generator can be started independently, but the equipment variety and complexity increase
Solution Approach 1:
The patent designs the power supply device with multi-functional capability, where the single integrated unit can serve as both generator and rectifier, and can be started by either diesel engine or external power source. This universal design eliminates the need for separate black-start devices for different generator types.
