Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plurality of heaters operate simultaneously to provide rich smoke and improved flavors, then the heating performance and aerosol generation quality are improved, but the power consumption increases causing voltage drop in low battery voltage or temperature states
Solution Approach 1:
The system performs preliminary detection of battery voltage and temperature states before enabling simultaneous heater operation. The processor checks whether the battery is in a low voltage or low temperature state, and only allows simultaneous operation of multiple heaters when the battery is in a normal state, preventing voltage drop before it occurs.
Solution Approach 2:
The system implements feedback control by continuously monitoring battery voltage and temperature states, and adjusting heater operation accordingly. When the battery enters a low voltage or low temperature state during simultaneous heater operation, the system automatically adjusts the heating strategy to maintain stable voltage and prevent system failure.
2Reliability
If the battery is in a low voltage or low temperature state, then the battery's voltage drop increases, but simultaneous operation of multiple heaters exacerbates the voltage drop causing system failure
Solution Approach 1:
The system applies preliminary anti-action by detecting low voltage or low temperature states in advance and preventing simultaneous heater operation during these conditions. The processor explicitly checks battery state before enabling multiple heaters, and takes countermeasures to avoid the harmful voltage drop before it can occur.
Solution Approach 2:
The system dynamically adjusts heater operation based on real-time battery state. When the battery is in a normal state, multiple heaters can operate simultaneously; when the battery enters a low voltage or low temperature state, the system dynamically changes the heating strategy to maintain system stability and prevent voltage drop.
3Reliability
If multiple heaters are used to deliver improved flavors, then the aerosol generation quality is enhanced, but the battery consumption increases reducing overall device efficiency
Solution Approach 1:
The system changes operational parameters based on battery state. When the battery is in a normal state, the system allows simultaneous heater operation with high power consumption for improved aerosol quality. When the battery enters a low voltage or low temperature state, the system changes parameters to reduce power consumption and extend battery life.
