Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional fracturing equipment is used, then fracturing operations can be performed, but the equipment footprint and environmental impact increase
Solution Approach 1:
The patent replaces traditional diesel-powered mechanical systems with an electrically-driven system. The electric motor drives the fracturing pump through an electrical power system, eliminating diesel engines and reducing harmful emissions. This substitution maintains full fracturing operational capability while significantly reducing environmental impact through cleaner energy conversion.
Solution Approach 2:
The patent changes the energy source parameter from chemical energy (diesel) to electrical energy. By introducing an electrical power system with battery banks and charge controllers, the system transforms the fundamental energy parameter, reducing harmful emissions while maintaining the mechanical output required for fracturing operations.
2Productivity
If multiple pumps are used to increase productivity, then fracturing efficiency improves, but device complexity increases
Solution Approach 1:
The patent combines multiple fracturing pumps into a single integrated mobile system with a common electrical power source. The dual pump configuration shares the same battery banks, charge controllers, and control systems, reducing overall equipment complexity compared to separate pump units while maintaining enhanced productivity through simultaneous or sequential operation of both pumps.
Solution Approach 2:
The electrical power system serves multiple functions: it powers both fracturing pumps, operates control systems, charges battery banks, and provides monitoring capabilities. This multi-functional design reduces the need for separate systems for each pump, simplifying the overall device configuration while enabling high-productivity multi-pump operations.
3Ease of operation
If remote control capability is added, then operational safety and efficiency improve, but device complexity increases
Solution Approach 1:
The patent introduces a control system with user interfaces and monitoring devices as intermediaries between the operator and the fracturing pumps. This intermediary layer enables remote operation and enhanced safety by allowing operators to control pump operations from a distance while maintaining full system functionality through electrical signaling and digital communication.
Solution Approach 2:
The control system incorporates feedback mechanisms that monitor pump operation, pressure levels, and system status, transmitting this information to remote operators. This feedback loop enables safe remote control by providing real-time system state information without requiring complex manual intervention, as the electrical system automatically communicates operational parameters.
