Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If fossil fuels are used in internal combustion engines, then desired efficiency and performance characteristics are achieved, but undesirable emissions are generated
Solution Approach 1:
The patent changes the chemical composition parameters of the fuel by using low carbon fuel blends (methanol, ethanol, methane, hydrogen) instead of traditional fossil fuels. This parameter change reduces carbon emissions while the control system adjusts operating parameters to maintain engine efficiency and performance characteristics.
Solution Approach 2:
The patent implements a feedback control system using exhaust sensors to monitor emissions and operational conditions. The controller receives feedback from these sensors and dynamically adjusts operating parameters to optimize the balance between engine performance and emissions reduction, ensuring that low carbon fuel blends operate at peak efficiency.
2Object-generated harmful factors
If low carbon fuel blends are used, then emissions are reduced, but engine performance and combustion optimization become more complex
Solution Approach 1:
The controller serves multiple functions: it receives initial fuel composition indications, implements feedforward adjustments based on fuel type, receives feedback from exhaust sensors, and dynamically adjusts operating parameters. This multi-functional approach consolidates the complexity into a single control unit that manages emissions reduction while optimizing engine performance across different low carbon fuel blends.
Solution Approach 2:
The system performs preliminary actions by receiving an initial indication of fuel blend composition and implementing feedforward adjustments before combustion occurs. This proactive approach prepares the control system with anticipated fuel characteristics, allowing it to pre-adjust operating parameters and reduce the complexity of real-time adjustments during combustion.
3Productivity
If feedforward and feedback control strategies are implemented, then combustion and emissions are optimized, but device complexity increases
Solution Approach 1:
The feedforward control strategy performs preliminary adjustments by receiving initial fuel composition indications and pre-adjusting operating parameters before combustion. This proactive preparation optimizes combustion for the specific fuel blend type, improving fuel efficiency while distributing the control complexity across predictable, pre-planned adjustments.
Solution Approach 2:
The feedback control strategy uses exhaust sensors to monitor actual combustion results and operational conditions, then dynamically adjusts operating parameters to optimize fuel efficiency and emissions. This closed-loop approach refines the combustion process in real-time, achieving high fuel efficiency while the controller integrates both feedforward and feedback mechanisms into a unified control system.
