Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a complete set of electrically-driven fracturing equipment is used, then environmental pollution is reduced and operation area is minimized, but power supply installation time increases to half to one month
Solution Approach 1:
The power generation system is divided into two separable conveyances: one carrying the gas turbine, generator, and auxiliary systems; the other carrying the intake-exhaust system. This segmentation allows each module to be transported and installed independently, reducing overall installation time while maintaining the environmental benefits of electrically-driven equipment.
Solution Approach 2:
The intake assembly and exhaust duct are pre-assembled on the second conveyance with lifting gears ready for deployment. This preliminary preparation enables rapid deployment at the well-site without requiring extensive on-site assembly, thus reducing installation time while preserving the complete electrically-driven system's environmental advantages.
2Reliability
If various parts of a power supply system require different assembly, transportation and installation methods, then system functionality is ensured, but installation time increases to half to one month
Solution Approach 1:
The lifting gears are integrated into the second conveyance structure, merging the transportation function with the lifting function. This unified design allows the intake-exhaust system to be both transported and erected using the same platform, reducing the need for multiple specialized assembly operations while ensuring proper system functionality.
Solution Approach 2:
The lifting gears are self-contained within the second conveyance, enabling the intake-exhaust system to lift and position itself relative to the first conveyance without requiring external cranes or additional heavy machinery. This self-service capability significantly reduces installation time while maintaining system reliability.
3Area of stationary object
If the power generation system is assigned onto two conveyances, then area occupation is reduced and transportation energy consumption is minimized, but structural complexity increases
Solution Approach 1:
The system is segmented into two conveyances to reduce area occupation and transportation energy consumption. The first conveyance carries the power generation components while the second carries the intake-exhaust system. This segmentation allows for more compact site footprint and optimized transportation logistics despite the increased structural division.
Solution Approach 2:
The second conveyance is designed with multi-functionality, serving both as a transportation platform and as a lifting mechanism through its integrated lifting gears. This universal design reduces the need for additional specialized equipment, thereby limiting the increase in structural complexity while achieving the area reduction goals.

AI summary
The present invention discloses a mobile power generation system. The whole power generation system is assigned onto two conveyances. A gas turbine, a generator, an intake chamber, an exhaust collector, and an auxiliary system are disposed on a first conveyance, an intake assembly and an exhaust duct are integrally disposed on a second conveyance. The second conveyance further includes at least four lifting gears, which are configured to separate the intake assembly and the exhaust duct from the second conveyance, and jack up the intake assembly and the exhaust duct so as to accommodate the power generation transport apparatus and move it to the bottom of the intake assembly and the exhaust duct. The intake assembly and the exhaust duct are then brought down by the lifting gears to dock with the intake chamber and the exhaust collector respectively. A seal docking can be achieved by the weights of the intake assembly and the exhaust duct themselves.
