Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the atomization amount is increased, then visual satisfaction is improved, but environmental restrictions worsen
Solution Approach 1:
The patent implements dynamic control of the vibrator's operating frequency and temperature based on user needs and environmental conditions. The processor adjusts the operating frequency within a predetermined range including the resonant frequency to control the vibrator temperature, enabling the system to adapt atomization output to different situations, thus resolving the contradiction between visual satisfaction and environmental restrictions
Solution Approach 2:
The patent changes the operating parameters (frequency and temperature) of the vibrator to control atomization amount. By adjusting the operating frequency within a predetermined range, the vibrator temperature is controlled to optimize atomization output, allowing the system to provide appropriate atomization levels for different environmental conditions
2Productivity
If the vibrator temperature is increased, then atomization efficiency is improved, but energy consumption increases
Solution Approach 1:
The patent optimizes the relationship between operating frequency and temperature by selecting frequencies within a predetermined range that achieves the desired atomization efficiency while minimizing energy consumption. The processor determines the operating frequency based on the correlation between frequencies and impedances to control the vibrator temperature efficiently
Solution Approach 2:
The patent incorporates impedance measurement as a feedback mechanism to monitor and control the vibrator's operating state. By measuring the impedance at different frequencies and using this information to determine the optimal operating frequency, the system can maintain efficient atomization while managing energy consumption
3Temperature
If the operating frequency is adjusted away from resonant frequency, then temperature control is improved, but vibration efficiency decreases
Solution Approach 1:
The patent dynamically adjusts the operating frequency within a predetermined range including the resonant frequency based on the desired temperature control. The processor determines the operating frequency by considering the correlation between frequencies and impedances, allowing the system to balance temperature control requirements with vibration efficiency
Solution Approach 2:
The patent performs preliminary measurement of the correlation between frequencies and impedances to establish the relationship before actual operation. This preliminary characterization allows the processor to determine the optimal operating frequency that achieves the desired temperature while maintaining adequate vibration efficiency
