Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If combustion gas injection is used for propulsion, then thrust generation is achieved, but weight and size increase due to fuel and storage tank requirements
Solution Approach 1:
The invention extracts and eliminates the combustion system (fuel tank, fuel, combustion chamber) from the propulsion device, replacing it with a motor-driven rotor system that generates thrust through electromagnetic forces and elastic body interactions, thereby significantly reducing weight while maintaining thrust capability
Solution Approach 2:
The invention replaces the chemical combustion mechanism with an electromagnetic motor system. The thrust-generator motor drives the rotor, which interacts with elastic bodies to generate thrust through mechanical vibrations and kinetic energy transfer, substituting chemical energy conversion with electromagnetic-to-mechanical energy conversion
2Force
If combustion gas injection is used for propulsion, then thrust generation is achieved, but device complexity increases due to fuel storage and injection systems
Solution Approach 1:
The invention removes the complex fuel storage tank, fuel injection system, and combustion control mechanisms, retaining only the essential thrust-generator motor and rotor assembly, thereby simplifying the overall device structure while maintaining propulsion functionality
Solution Approach 2:
The rotor serves multiple functions: it acts as both the driven element of the motor and the thrust-generating element through its interaction with elastic bodies. This multi-functionality reduces the number of separate components needed, simplifying the device structure

AI summary
The propulsion device 1 comprises a thrust generator 11 and a reverse rotational force generator 70. The thrust generator is configured to generate thrust in one direction perpendicular to the central axis and to generate rotational force in the circumferential direction. The reverse rotational force generator is coupled to the thrust generator and is configured to generate a rotational force in an opposite direction to the rotational force generated by the thrust generator.
