Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If carbon capture and storage methods are used to reduce CO2 emissions, then CO2 emissions are reduced, but the process becomes costly and energy-intensive
Solution Approach 1:
The patent changes the chemical parameters of the combustion process by introducing catalysts (lithium, boron, aluminum compounds) that alter the reaction pathways. This enables direct reduction of CO2 emissions at the source through modified combustion chemistry rather than post-combustion capture, thereby reducing energy consumption while maintaining emission reduction benefits
Solution Approach 2:
The patent converts the harmful effect of complete combustion (which produces CO2) into a beneficial process by using catalysts to promote alternative reaction pathways. The catalysts enable partial oxidation and carbonation reactions that produce desirable products while reducing CO2 emissions, effectively turning the harmful complete combustion process into a more beneficial partial combustion process
2Object-generated harmful factors
If carbon capture and storage methods are used to reduce CO2 emissions, then CO2 emissions are reduced, but the process becomes costly
Solution Approach 1:
The patent employs inexpensive catalysts such as lithium compounds, boron compounds, and aluminum compounds that can be added in small quantities to the fuel. These cheap catalysts provide effective CO2 reduction without requiring expensive infrastructure like carbon capture and storage systems, making the solution economically viable for widespread implementation
Solution Approach 2:
The patent extracts and eliminates the need for complex carbon capture and storage infrastructure by addressing CO2 reduction at the combustion source through catalytic modification. This extraction of the CO2 reduction function from post-combustion processing eliminates the associated high costs of capture, compression, and storage systems
3Object-generated harmful factors
If conventional catalysts are used to reduce emissions, then some pollution is reduced, but thermal efficiency does not improve significantly
Solution Approach 1:
The patent employs composite catalytic systems combining multiple elements (lithium, boron, aluminum) and their compounds to achieve synergistic effects. This composite approach simultaneously reduces pollution emissions and improves thermal efficiency by creating a comprehensive catalytic system that addresses both objectives, unlike conventional single-catalyst approaches
4Object-generated harmful factors
If lithium catalyst is added to fuel, then CO2 and carbon oxide emissions are reduced, but fuel composition must be modified
Solution Approach 1:
The patent develops lithium-based catalysts that are universally applicable across different fuel types including gasoline, diesel, and other hydrocarbon fuels. The catalyst can be incorporated through various methods (fuel blending, injection systems) and maintains effectiveness across diverse combustion applications, providing broad fuel compatibility while reducing carbon oxide emissions

AI summary
An afterburner system and method for reducing the CO2 and other pollutants produced by the combustion of a fuel in a combustion chamber while maintaining or increasing the efficiency of said combustion includes feeding a catalyst, preferably lithium and/or boron to the afterburner, or a preconditioning afterburner, along with the exhaust from the combustion chamber. The presence of the catalyst in the after burner results in further reduction of pollutants generated by the combustion in the combustion chamber.
