Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a constant voltage is repeatedly applied to the heater to detect resistance value and control temperature, then the temperature control capability is improved, but the response speed and precision are insufficient
Solution Approach 1:
The patent applies periodic action by repeatedly applying constant voltage to the heater in cycles, measuring resistance values during each cycle, and using this periodic measurement to track temperature changes over time. This enables the control unit to detect temperature trends and adjust heating accordingly, improving both response speed and precision through continuous periodic monitoring rather than single-point measurement.
2Temperature
If the heating duration is extended to ensure adequate heating, then the temperature stability is improved, but the aerosol source consumption increases
Solution Approach 1:
The patent implements feedback by measuring the resistance value of the heater during voltage application and using this measurement to determine the actual temperature state. The control unit compares the measured resistance with target values and adjusts the heating duration and voltage application accordingly. This feedback mechanism allows the system to achieve adequate heating temperature stability while minimizing unnecessary heating time, thereby reducing aerosol source consumption.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting the voltage application duration and intensity based on real-time resistance measurements. The control unit modifies heating parameters (voltage duration, power level) according to the measured temperature state, enabling the system to reach target temperature efficiently without excessive heating time, thus balancing temperature stability with aerosol source conservation.
