Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If diesel-generated mechanical power is used to power hydraulic fracturing equipment, then sufficient power is available to operate pumps, blenders, cranes, and wireline units, but the system produces harmful emissions, generates excessive noise, requires constant fuel transportation, and increases safety risks
Solution Approach 1:
The patent replaces the diesel mechanical power system with an electrical power system using battery-powered generators. This substitution eliminates the harmful emissions and noise associated with diesel engines while providing reliable electrical power to drive electric motors that power the hydraulic fracturing equipment including pumps, blenders, cranes, and wireline units
Solution Approach 2:
The patent changes the energy source parameter from chemical energy (diesel) to electrical energy (battery-powered generators). This parameter change fundamentally alters the system's environmental impact by eliminating exhaust emissions and reducing noise, while maintaining the ability to deliver sufficient power through electrical motors
2Power
If heavy diesel engines are used to provide sufficient power for fracturing operations, then the equipment can operate pumps and other components, but the equipment requires large amounts of heavy trailers and trucks for transportation
Solution Approach 1:
The patent replaces heavy diesel engines with battery-powered electrical generators and electric motors. This substitution dramatically reduces the weight of moving equipment while maintaining sufficient power output, as electrical motors are significantly lighter than equivalent diesel engines and eliminate the need for heavy fuel storage and transportation infrastructure
3Duration of action of moving object
If diesel fuel is constantly transported and delivered to the well site, then the equipment can maintain operation, but significant carbon dioxide emissions are generated
Solution Approach 1:
The patent replaces the diesel fuel supply chain with an electrical power supply system using battery-powered generators. This substitution eliminates carbon dioxide emissions from fuel combustion and transportation while maintaining operational continuity, as batteries can store sufficient energy to power fracturing operations for extended periods without requiring fuel delivery
Solution Approach 2:
The patent extracts and removes the diesel fuel component from the system entirely, replacing it with an electrical energy storage and delivery system. This extraction eliminates the harmful carbon dioxide emissions associated with diesel fuel transportation and combustion while maintaining the system's ability to provide continuous power for fracturing operations
4Reliability
If onsite refueling is performed during operations, then the equipment can maintain power supply, but the risks of fuel leaks, fires, and other accidents increase
Solution Approach 1:
The patent replaces the diesel fuel storage and refueling system with an electrical battery-powered system. This substitution eliminates safety risks associated with fuel leaks and fires, as electrical batteries do not present the same combustion hazards as diesel fuel, while maintaining reliable power supply to operate pumps, blenders, cranes, and wireline units throughout fracturing operations
