Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a boiler combustion model is designed and configured using multiple model types (ARX, NARX, state space models) with systematic input/output design and verification, then the accuracy and stability of the combustion model is improved, but the device complexity and modeling time increase
Solution Approach 1:
The combustion model design process is segmented into distinct modules: model type selection (ARX, NARX, state space), input/output design, model generation, verification, and modification. Each module handles a specific aspect of the modeling process, making the complex task manageable and systematic while ensuring high model accuracy through thorough verification at each stage.
Solution Approach 2:
The system performs preliminary model verification and simulation before final deployment. Multiple model types are pre-configured and tested to identify the most suitable model for specific combustion conditions. This preliminary action ensures that only verified, accurate models are implemented, reducing the need for later modifications and maintaining high precision.
2Object-generated harmful factors
If combustion efficiency is increased through optimized boiler combustion models, then pollution exhaust gas levels are reduced, but the operational cost for model configuration and verification increases
Solution Approach 1:
The system implements a feedback mechanism where model verification results and simulation outcomes are used to automatically adjust and optimize combustion parameters. This closed-loop approach continuously improves combustion efficiency and reduces pollution while minimizing the need for manual intervention and expensive reconfiguration, as the system self-optimizes based on performance data.
Solution Approach 2:
The system optimizes combustion by dynamically adjusting key parameters such as air-fuel ratio, combustion temperature, and oxygen levels based on real-time conditions. By changing these parameters through verified models, the system achieves better combustion efficiency and lower emissions without requiring expensive hardware modifications or frequent manual tuning.
3Productivity
If incomplete combustion is reduced through accurate combustion modeling, then combustion efficiency is improved, but the complexity of model verification and modification increases
Solution Approach 1:
The system creates simplified digital copies (virtual models) of the boiler combustion process using ARX, NARX, and state space models. These virtual models replicate combustion behavior without requiring physical experimentation, allowing thorough verification and testing of different combustion scenarios. This copying approach enables accurate efficiency optimization while reducing the complexity of physical verification procedures.
