Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If one ultrasonic vibrator is driven at a fixed frequency (180 kHz±5 kHz), then the device structure is simple, but it cannot appropriately atomize chemical liquids with different target frequencies
Solution Approach 1:
The oscillation unit is segmented into multiple independent oscillation elements (first oscillation element, second oscillation element, etc.), each capable of generating a specific frequency component. This allows the system to select different frequency components based on the liquid type, achieving versatility while maintaining a modular structure that doesn't overly complicate the overall device.
Solution Approach 2:
The oscillation unit is designed with multi-functionality by incorporating multiple oscillation elements that can generate different frequency components (first frequency component, second frequency component, etc.). A single oscillation unit can thus serve multiple purposes by selecting the appropriate frequency component based on the liquid's atomization requirements, eliminating the need for multiple separate devices.
2Adaptability or versatility
If multiple ultrasonic vibrators with different frequencies are used, then liquids with different target frequencies can be atomized, but the device complexity increases
Solution Approach 1:
The system incorporates dynamic selection capability where the oscillation unit can switch between different frequency components (first, second, and additional frequency components) based on the liquid type being processed. This dynamic adaptability allows the device to respond to various needs without requiring a fixed configuration for each liquid type, maintaining versatility while managing complexity through intelligent control.
Solution Approach 2:
The invention changes the operating parameters (frequency components) of the oscillation unit based on the liquid type. By adjusting which frequency component is activated (first frequency component for first liquid, second frequency component for second liquid, etc.), the system achieves adaptability to different liquids without physically changing the oscillation elements themselves, thus managing device complexity.
3Adaptability or versatility
If a fixed frequency oscillation unit is used, then the device is easy to operate, but it cannot respond to various needs of different liquid types
Solution Approach 1:
The system incorporates automatic frequency selection capability where the oscillation unit can autonomously determine and switch between different frequency components based on the liquid type being processed. This self-service feature reduces the need for manual adjustment by the operator, maintaining ease of operation while achieving adaptability to different liquid types with varying viscosities and target frequencies.
Solution Approach 2:
The oscillation unit dynamically adapts its frequency output based on the processing requirements. By incorporating dynamic frequency selection between first, second, and additional frequency components, the system responds to various liquid types automatically, maintaining operational simplicity for the user while achieving high adaptability to different viscosity and frequency requirements.

Enables the nebulizer to effectively atomize liquids with different target frequencies, enhancing its versatility and efficiency without requiring frequent adjustments in settings, and allowing for easy replacement of components for different liquid types.
Implementation Method 1
the vibration surface of the ultrasonic vibrator is vibrated at a certain frequency (within a range of 180 kHz±5 kHz) substantially matching the resonance frequency of the ultrasonic vibrator
Implementation Method 2
the vibration surface of the ultrasonic vibrator is vibrated at a certain frequency... This causes the chemical liquid to be atomized and sprayed through the mesh portion
