Engineering Contradiction Analysis
1Productivity
If fossil fuels are used in conventional internal combustion engines, then the engines can generate mechanical work, but the supply is limited and greenhouse gas emissions increase
Solution Approach 1:
The patent changes the fundamental parameter of fuel composition from fossil-based hydrocarbons to nanoscale nuclear fuel particles embedded in a carrier fluid. This parameter change enables sustained energy supply through nuclear fission while eliminating greenhouse gas emissions, as the nuclear reaction process does not produce CO2 or other atmospheric pollutants.
Solution Approach 2:
The patent replaces the chemical combustion mechanism with a nuclear fission mechanism. Instead of relying on chemical oxidation reactions that consume oxygen and produce CO2, the system uses neutron-induced nuclear fission of uranium-235 atoms, fundamentally substituting the energy release mechanism to eliminate harmful emissions while providing sustained energy supply.
2Use of energy by moving object
If nanofuel with million times energy density is used, then energy efficiency is improved, but the device complexity increases due to neutron source and reflector requirements
Solution Approach 1:
The patent embeds nanoscale uranium-235 fuel particles within a carrier fluid matrix, creating a nested structure where the nuclear fuel is contained within droplets or particles that are themselves suspended in a deliverable fluid medium. This nesting enables the high-energy-density nuclear fuel to be handled and delivered using conventional fluid injection systems.
Solution Approach 2:
The patent introduces a carrier fluid as an intermediary substance that facilitates the delivery and control of nanoscale nuclear fuel particles. This intermediary enables the nuclear fuel to be injected, mixed, and controlled using conventional engine fuel delivery infrastructure, thereby managing the complexity of handling such high-energy-density material.
3Ease of operation
If conventional fossil fuels are used, then the fuel is easy to handle and deliver, but the energy density is low compared to nanofuel
Solution Approach 1:
The patent utilizes hydraulic principles by formulating nanofuel as a liquid suspension or emulsion that can be pumped, injected, and delivered through conventional hydraulic fuel delivery systems. This approach maintains ease of handling by using fluid mechanics to transport the nanoscale nuclear fuel particles, leveraging existing infrastructure designed for liquid fossil fuels.
