Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the atomization amount is increased to provide visual satisfaction, then the aerosol production volume increases, but the environmental restrictions and user convenience deteriorate
Solution Approach 1:
The patent implements dynamic control of the vibrator operating frequency based on real-time impedance detection. The processor adjusts the frequency within a predetermined range including the resonant frequency to optimize atomization output. This dynamic adjustment allows the device to adapt atomization levels to different usage conditions, providing visual satisfaction when needed while maintaining environmental friendliness during normal operation.
Solution Approach 2:
The patent changes the operating parameters of the vibrator by adjusting its frequency within a predetermined range around the resonant frequency. By monitoring impedance changes and selecting optimal frequencies, the system can vary the atomization amount to match user needs and environmental conditions, resolving the contradiction between visual satisfaction and environmental restrictions.
2Speed
If the vibrator temperature is increased to reduce aerosol generating material viscosity, then the atomization speed improves, but the energy consumption increases
Solution Approach 1:
The patent implements a pre-heating function where the processor controls the vibrator to operate at a frequency that generates heat before the actual atomization process. This preliminary heating reduces the viscosity of the aerosol generating material in advance, so when atomization is needed, the material is already in an optimal state for quick atomization without requiring excessive energy during the atomization moment.
Solution Approach 2:
The system uses periodic heating cycles where the vibrator frequency is adjusted to generate heat during idle periods or before use, then switched to atomization-optimized frequencies when needed. This periodic action pattern allows the system to maintain low viscosity material ready for atomization while managing overall energy consumption through controlled heating intervals.
3Productivity
If the vibrator operates at resonant frequency for efficient atomization, then the atomization effectiveness improves, but the temperature control precision deteriorates
Solution Approach 1:
The patent dynamically adjusts the vibrator frequency within a predetermined range around the resonant frequency based on real-time impedance measurements. The processor monitors impedance changes and selects frequencies that balance atomization effectiveness with temperature control requirements. This dynamic frequency adjustment allows the system to operate near resonance for efficiency while maintaining precise temperature control by avoiding sustained operation at the exact resonant peak.
Solution Approach 2:
The system implements feedback control by continuously monitoring the vibrator's impedance and using this information to adjust the operating frequency. The processor analyzes impedance changes to determine the optimal frequency that achieves both effective atomization and desired temperature control, creating a closed-loop system that resolves the contradiction between productivity and precision.
