Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If conventional gas-powered jet engines are used, then thrust and propulsion are achieved, but combustion is required which reduces efficiency and increases emissions
Solution Approach 1:
The patent replaces the combustion-based mechanical system with an electromagnetic system. Electric motors with rotating magnetic fields directly drive the compressor and generate thrust through electromagnetic forces, eliminating the need for combustion chambers and thermal energy conversion, thus removing emissions while maintaining propulsion power
Solution Approach 2:
The invention changes the fundamental operating parameters from thermal/chemical energy conversion to electromagnetic energy conversion. By using electric motors that convert electrical energy directly to mechanical rotation and thrust, the system achieves the same propulsion effect without the harmful byproducts of combustion
2Power
If combustion chambers and gas turbines are used, then power generation is achieved, but system complexity increases
Solution Approach 1:
The patent extracts and removes the combustion chamber and gas turbine components from the jet engine system. By eliminating these complex thermal management systems and replacing them with electric motors, the invention simplifies the overall engine structure while maintaining power generation capability through electromagnetic conversion
Solution Approach 2:
The electric motor serves multiple functions simultaneously: it acts as both the power generation device and the compressor driver, eliminating the need for separate combustion chamber and turbine components. This multi-functionality reduces system complexity while achieving the same power output
3Object-generated harmful factors
If electric motors with magnets and coils are used, then combustion is eliminated, but new technical challenges arise in electromagnetic system design
Solution Approach 1:
The patent replaces complex thermal-mechanical systems with electromagnetic systems. The electric motor uses rotating magnetic fields generated by coils and magnets to directly drive the compressor and generate thrust, eliminating combustion-related emissions while the electromagnetic design challenges are managed through standard motor engineering principles
