Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a conventional heating device is used, then the heating operation can be performed, but the heating rate is slow and heating time is long
Solution Approach 1:
The patent replaces the conventional heating device with an instantaneous electric heater that directly contacts the portions to be heated. This substitution of heating mechanism enables rapid heating by directly converting electrical energy to thermal energy at the target components, dramatically reducing heating time while maintaining effective temperature increase.
Solution Approach 2:
The patent extracts the heating function from the main turbine engine system by using the auxiliary power unit to drive an instantaneous electric heater separately. This separation allows the heating operation to be performed independently and rapidly without being constrained by the main system's operational limitations, thus reducing overall heating time.
2Temperature
If a conventional heating device is used, then the heating operation can be performed, but energy consumption is increased
Solution Approach 1:
The patent substitutes the conventional heating device with an instantaneous electric heater powered by the auxiliary power unit. This replacement creates a more efficient energy conversion path, directly heating the target components without the energy losses associated with conventional indirect heating methods, thereby improving heating efficiency and reducing overall energy consumption.
Solution Approach 2:
The auxiliary power unit serves dual purposes: it powers the fracturing operation and simultaneously provides power for the heating operation through the instantaneous electric heater. This self-service arrangement eliminates the need for separate external heating energy sources, optimizing energy utilization and reducing total energy consumption.
