Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for electric power generation, oil cooling, and fluid circulation, then each device can be optimized independently, but the system volume and weight increase
Solution Approach 1:
The patent combines the power generation device and fluid circulation device into a single integrated unit. The power generation rotor and fluid circulation rotor share a common structure, allowing both functions to be performed by one device rather than two separate devices, thereby reducing overall system weight while maintaining functional optimization
Solution Approach 2:
The integrated device serves multiple functions simultaneously: it generates electric power through the power generation part while also circulating fluid for cooling and lubrication through the pumping mechanism. This multi-functionality eliminates the need for separate dedicated devices for each function
2Reliability
If separate devices are used for electric power generation, oil cooling, and fluid circulation, then each device can be optimized independently, but the system complexity increases
Solution Approach 1:
By merging the power generation device and fluid circulation device into one integrated unit with a shared rotor structure, the patent reduces the number of separate components and connections required, thereby simplifying the overall system architecture while preserving the ability to optimize each functional part
3Temperature
If oil is forcibly sprayed onto motor components for cooling, then cooling effectiveness is improved, but the system requires additional separate cooling devices
Solution Approach 1:
The patent integrates the fluid circulation pumping mechanism directly into the power generation rotor structure. The inclined plate and piston components that enable fluid pumping are built into the rotor assembly, eliminating the need for external separate cooling devices while maintaining effective fluid circulation for cooling and lubrication

AI summary
Disclosed herein is an electric power and thermal management system in which, when a shaft is rotated due to an operation of a power part, generation of electric power and a circulation of a fluid are performed together so that the generation of the electric power and a circulation structure of oil are integrated, and thus a layout can be reduced, and a structure can be simplified. In addition, in a state in which the generation of the electric power and the circulation structure of the oil are integrated, a circulation amount of the oil is adjusted according to an angle of an inclined plate constituting a pumping mechanism so that an oversupply of the oil to parts through which the oil is circulated can be prevented.
