Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional combustion efficiency measurement methods are used, then the system is simple to operate, but the measurement precision is insufficient leading to incomplete combustion
Solution Approach 1:
The patent segments the combustion analysis into multiple spectral wavelength bands (e.g., 4.2-4.3 μm for CO2, 3.3-3.5 μm for hydrocarbons, 4.5-4.8 μm for CO). By dividing the spectral analysis into specific bands, each detector can precisely measure particular combustion products, achieving high measurement precision without requiring a single overly complex measurement system
Solution Approach 2:
The patent employs a multi-functional measurement system where a single apparatus simultaneously measures multiple combustion parameters (CO2 concentration, hydrocarbon concentration, CO concentration, and combustion efficiency) across different spectral bands. This universal approach consolidates multiple measurement functions into one system, improving precision while managing complexity
2Measurement precision
If visual inspection methods are used, then the device complexity is low, but the measurement precision and reliability are insufficient
Solution Approach 1:
The patent replaces manual visual inspection with an automated optical measurement system. Instead of relying on human spotters to visually assess combustion, the system uses spectral analysis detectors to automatically measure combustion product concentrations and calculate efficiency, significantly improving precision and reliability
Solution Approach 2:
The patent implements automatic feedback control where the measured spectral data is processed to calculate combustion efficiency, which then feeds back to the control system to automatically adjust combustion parameters. This closed-loop feedback mechanism ensures continuous optimization of combustion efficiency without manual intervention
3Reliability
If constant tuning and monitoring are performed, then the combustion efficiency can be maintained, but the loss of time and operational complexity increase
Solution Approach 1:
The patent enables the combustion system to self-regulate through automatic control. The measurement system continuously monitors combustion products and the control system automatically adjusts combustion parameters to maintain optimal efficiency, eliminating the need for manual tuning and reducing operational time loss
Solution Approach 2:
The patent implements continuous real-time measurement and control of combustion efficiency. Instead of periodic manual checks, the spectral analysis system continuously monitors combustion products and provides ongoing feedback for automatic adjustment, ensuring consistent efficiency maintenance without interrupting operations
