Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If traditional combustion of fossil energy carriers is used, then energy is produced, but pollutants such as nitrogen oxide (NOx), carbon dioxide (CO2), soot and dust particles are generated
Solution Approach 1:
The patent changes the chemical parameters of the combustion process by using hydrogen and oxygen gases instead of fossil fuel carbon hydrocarbons. This fundamental parameter change in fuel composition eliminates carbon-based pollutants (CO2, soot, dust) while maintaining energy production through the hydrogen-oxygen combustion reaction.
Solution Approach 2:
The patent converts the previously harmful combustion process into a beneficial one by using hydrogen fuel. The combustion of hydrogen produces water vapor instead of carbon-based pollutants, transforming the combustion process from a source of environmental harm into an environmentally friendly energy production method.
2Object-generated harmful factors
If hydrogen gas and oxygen gas are supplied separately to the combustion chamber, then pollution-free combustion is achieved, but the device complexity increases due to additional inlet valves and gas supply systems
Solution Approach 1:
The patent segments the gas supply system into separate inlet openings for hydrogen gas and oxygen gas, with dedicated inlet valves for each gas. This segmentation allows independent control of each gas flow, enabling precise stoichiometric mixing ratio control while maintaining a relatively simple overall system architecture that avoids complex mixing equipment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The engine operates without producing pollutants, achieving a more environmentally friendly combustion process by utilizing the hydrogen-oxygen mixture for efficient energy conversion and water recycling, resulting in a cleaner energy output.
Implementation Method 1
a thermolysis catalyst forms the combustion chamber covering, which thermolysis catalyst has two hollow cylinders arranged at a distance from one another and concentrically and surrounding an intermediate space
Implementation Method 2
the walls of the hollow cylinders defining the intermediate space are provided with a metal coating for release of the heat of combustion acting on the inner hollow cylinder
Implementation Method 3
The spring valve can be opened at about 160 degrees in the piston positions from the bottom dead center to shortly before the upper dead center
