Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional jet engines use combustion and gas turbines, then they can generate thrust, but they have limitations in efficiency and produce harmful emissions
Solution Approach 1:
The patent replaces the combustion-based mechanical system with an electromagnetic system. Electric motors with rotors and stators generate rotational motion directly through electromagnetic forces, eliminating the need for combustion chambers and gas turbine mechanics. This substitution removes harmful emissions entirely while improving energy efficiency through direct electromagnetic-to-mechanical energy conversion.
Solution Approach 2:
The invention changes the fundamental operating parameters from thermal combustion processes to electromagnetic field interactions. By using electric motors that convert electrical energy directly to rotational mechanical energy, the system operates at higher efficiency levels without the thermal losses inherent in combustion-based systems, thereby improving both efficiency and reducing emissions.
2Object-generated harmful factors
If jet engines eliminate combustion chambers and gas turbines, then emissions are reduced, but the propulsion mechanism must be fundamentally changed
Solution Approach 1:
The patent substitutes complex combustion chambers, fuel injection systems, and gas turbine mechanics with relatively simpler electric motor components (rotors, stators, and magnets). This electromagnetic approach eliminates the need for combustion-related subsystems while providing a more compact and potentially easier-to-maintain propulsion mechanism.
3Stress or pressure
If conventional engines use compressors to increase air pressure, then combustion efficiency is improved, but the system requires fuel and combustion infrastructure
Solution Approach 1:
The patent replaces the mechanical compressor system that requires fuel combustion with an electrically-driven compression system. Electric motors drive the compression process directly, eliminating the need for combustion infrastructure while maintaining the necessary air pressure levels for efficient operation.
