Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If hydrogen is added to gasoline in the internal combustion engine, then hydrocarbon emissions are reduced, but carbon capture efficiency is insufficient
Solution Approach 1:
The system extracts and separates carbon dioxide from the exhaust gas stream using a condensation trap and filtration system. The catch device condenses water vapor and CO2 from the exhaust, then a filter removes the carbon dioxide, effectively extracting the harmful carbon component from the emissions stream.
Solution Approach 2:
The patent introduces intermediate devices between the engine exhaust and the environment: a catch device that condenses exhaust components, and a filter that captures carbon dioxide. These intermediary components enable the separation and capture of carbon from the exhaust stream before release.
2Reliability
If a catch device and filter are added to capture carbon, then carbon capture efficiency is improved, but device complexity increases
Solution Approach 1:
The catch device serves multiple functions: it condenses water vapor from exhaust, captures carbon dioxide through the filter, and potentially recovers other valuable components. This multi-functionality reduces the need for separate dedicated devices for each function, thereby managing system complexity while achieving effective carbon capture.
Solution Approach 2:
The system recovers carbon dioxide that would otherwise be discarded into the atmosphere. By capturing and concentrating CO2 through condensation and filtration, the system transforms waste emissions into a recoverable resource, potentially for storage or utilization purposes.

AI summary
An automobile includes an internal combustion engine having an emission control system, intake manifold and an exhaust manifold. A hydrogen source is positioned to deliver hydrogen to the intake manifold. Hydrogen and gasoline combustion takes place in a cylinder of the internal combustion engine and a catch device is positioned to receive fluid mixture from the exhaust manifold of the internal combustion engine. The catch device condenses the fluid mixture and a filter receives the condensed fluid mixture from the catch device and filters the condensed fluid mixture. A container is positioned to receive the filtered fluid mixture.
