Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If power allocation between energy suppliers is not optimized, then operating efficiency decreases, but service life is shortened
Solution Approach 1:
The patent implements dynamic power allocation by continuously monitoring output power and power change rates of different energy suppliers, and adjusting their reference powers in real-time based on current operating conditions. This dynamic adjustment ensures optimal operating efficiency while preventing any single supplier from being over-stressed, thereby extending service life.
Solution Approach 2:
The patent changes the operating parameters (reference power) of energy suppliers based on their current state and power change rates. By adjusting these parameters dynamically, the system achieves both high operating efficiency and extended service life through optimized power distribution.
2Speed
If power change rate is not controlled, then response speed improves, but energy supplier imbalance increases
Solution Approach 1:
The patent employs feedback control by continuously monitoring the output power and power change rates of energy suppliers, then using this information to adjust reference powers. This feedback mechanism maintains energy supply balance while enabling rapid response to changing load conditions.
Solution Approach 2:
The patent introduces reference power as an intermediary parameter that mediates between the actual output power and the required power allocation. This intermediary enables smooth transitions and maintains balance while allowing rapid response to power demands.
3Productivity
If gas flow rate and furnace temperature are not optimized, then conversion efficiency improves, but energy supplier performance deteriorates
Solution Approach 1:
The patent optimizes gas flow rates and furnace temperatures by dynamically adjusting these parameters based on the operating conditions and power requirements of energy suppliers. This ensures high conversion efficiency while maintaining optimal performance and extending the service life of energy suppliers.
