Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ultrasonic wave is continuously applied to atomize raw material liquid, then atomization efficiency is improved, but bubbles are generated from intermediate liquid to inhibit ultrasonic wave propagation
Solution Approach 1:
The patent extracts and removes bubbles from the intermediate liquid using a degassing mechanism before the ultrasonic wave is applied. This prevents bubbles from inhibiting ultrasonic wave propagation while maintaining continuous atomization operation.
Solution Approach 2:
The patent applies a preliminary degassing action to remove bubbles from the intermediate liquid before the ultrasonic atomization process begins. This preliminary action ensures that the ultrasonic wave can propagate continuously without interference from bubbles.
2Object-affected harmful factors
If angle of bottom face of raw material container is provided relative to liquid level to avoid bubble adhesion, then bubble adhesion is reduced, but raw material liquid depth becomes ununiform and atomization is insufficient
Solution Approach 1:
Instead of changing the container geometry to prevent bubble adhesion, the patent extracts bubbles using a degassing mechanism. This allows the container to maintain a horizontal bottom face for uniform liquid depth while still preventing bubble interference through active bubble removal.
Solution Approach 2:
The patent introduces a degassing mechanism as an intermediary system that handles bubble removal separately from the container structure. This mediator approach allows the container to maintain simple geometry for uniform liquid distribution while bubbles are handled by the degassing system.
3Productivity
If multiple ultrasonic wave generators are employed to improve atomization, then atomization efficiency is improved, but apparatus structure becomes complex and expensive
Solution Approach 1:
The patent removes bubbles that would otherwise require multiple ultrasonic generators to effectively atomize. By extracting bubbles through the degassing mechanism, a single ultrasonic wave generator can achieve sufficient atomization efficiency without increasing apparatus complexity.

AI summary
A film-forming atomizer atomizing a raw material liquid with ultrasonic wave to generate a raw material mist, includes: a raw material container containing the raw material liquid; a propagation vessel containing an intermediate liquid as a medium for propagating the ultrasonic wave to the raw material liquid; a support mechanism to support the raw material container so that at least a part of the raw material container is positioned in the intermediate liquid; a circulation mechanism to circulate the intermediate liquid; an ultrasonic wave generator to generate and apply the ultrasonic wave to the propagation vessel; and a degassing mechanism to discharge a gas in the intermediate liquid out of the film-forming atomizer.
