Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the heater temperature is controlled based on a preset temperature profile, then the smoking taste can be optimized, but the measured temperature of the heater differs from the actual temperature at which the aerosol generating material is heated
Solution Approach 1:
The patent applies feedback by measuring the actual temperature of the aerosol generating material and using this measurement to correct the heater temperature control. The system continuously monitors the material temperature and adjusts the heater power accordingly to maintain the desired temperature profile, resolving the discrepancy between measured heater temperature and actual material temperature.
Solution Approach 2:
The patent replaces direct mechanical/thermal measurement of heater temperature with an indirect measurement approach. Instead of measuring the heater temperature directly, the system measures the temperature of the aerosol generating material and uses this information to infer and control the actual heating temperature, substituting a more reliable measurement method.
2Measurement precision
If multiple temperature correction algorithms are used to improve temperature accuracy, then the temperature control precision is improved, but the device complexity increases
Solution Approach 1:
The patent segments the temperature correction process into multiple distinct algorithms, each optimized for specific temperature ranges or operating conditions. By dividing the correction process into separate manageable algorithms rather than one complex unified algorithm, the system achieves high accuracy while maintaining manageable complexity through modular design.
Solution Approach 2:
The patent implements dynamic selection of temperature correction algorithms based on current operating conditions. The system dynamically switches between different correction algorithms depending on the temperature range or operational state, allowing optimal accuracy for each condition without requiring a single overly complex algorithm to handle all scenarios.
