Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ultrasonic atomization apparatuses face challenges in accurately and responsively measuring the amount of material solution mist supplied, due to delays in information and weight measurement inaccuracies caused by the inclusion of mist supply pipes in the measurement target.
Innovation Solution
An ultrasonic atomization apparatus with a non-contact mist supply pipe and a leakproof tank, where the non-contact mist supply pipe has overlapping and non-overlapping regions, and a sealing liquid in the pipe overlapping space, allowing for accurate weight measurement of the material solution container and ultrasonic transducer without including the mist supply pipe in the measurement target.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the mist supply pipe is included in the weight measurement target, then the measurement system is simpler to implement, but the measurement precision deteriorates due to weight distribution effects and inability to accurately measure the material solution weight
Solution Approach 1:
The system divides the measurement target into two separate parts: the material solution container (including atomization container and separator cup) and the mist supply pipe. The scale measures only the container weight, while the flowmeter measures the material solution flow rate. This segmentation eliminates the weight distribution effect caused by the mist supply pipe being included in the measurement target, thereby improving measurement precision.
2Measurement precision
If the mist supply pipe is excluded from the measurement target, then the measurement precision improves, but the device complexity increases due to additional components and configuration
Solution Approach 1:
The flowmeter serves multiple functions: it measures the material solution flow rate (replacing the weight measurement function for the solution), and its placement outside the measurement target simplifies the overall measurement system configuration. This multi-functionality approach reduces device complexity while maintaining high measurement precision.
3Device complexity
If conventional weight measurement is used including mist supply pipe, then the system structure is simpler, but the responsiveness deteriorates due to delays in information about actual mist amount
Solution Approach 1:
The flowmeter measures the material solution flow rate in advance (upstream) before it enters the atomization container. This preliminary measurement provides real-time information about the amount of material solution being atomized, eliminating delays in information about the actual mist amount generated. The control system can immediately adjust parameters based on this advance information.
