Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual exhaust sensors are assigned to each gas burner for combustion adaptation, then combustion control precision is improved, but system cost increases
Solution Approach 1:
The patent merges the exhaust sensing function into a single common sensor that serves multiple burners, eliminating the need for individual sensors at each burner. This consolidation reduces system cost while maintaining combustion control precision through centralized monitoring and adaptation of the common exhaust gas composition.
Solution Approach 2:
The common exhaust sensor performs multiple functions: monitoring exhaust gas composition from multiple burners, providing combustion adaptation data for the entire system, and enabling cost-effective scaling. This universal sensor replaces multiple specialized sensors, reducing overall system complexity and cost.
2Device complexity
If a common exhaust sensor is used for multiple gas burners, then system cost is reduced, but measurement precision deteriorates due to interference from multiple burners
Solution Approach 1:
The system implements periodic single-burner operation cycles where each burner is activated individually while others remain off. During these periodic intervals, the common exhaust sensor measures exhaust gas composition from a single burner source, ensuring high measurement precision for combustion adaptation without interference from multiple simultaneous burners.
Solution Approach 2:
The patent extracts the measurement function from the operational phase and performs it during dedicated single-burner intervals. By separating the measurement action from continuous multi-burner operation, the system ensures that the common sensor receives uncontaminated exhaust signals from individual burners, maintaining precision while using cost-effective single sensor architecture.
