Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a disc-shaped ultrasonic atomization sheet is used with a cylindrical fixing sleeve, then the structure is simple and easy to manufacture, but the high-frequency working amplitude is limited and the atomization effect is poor
Solution Approach 1:
The piezoelectric substrate is divided into a fixed section (connected to the fixing sleeve) and an oscillating section (free to vibrate). This segmentation allows the oscillating section to achieve larger amplitude vibrations for better atomization effect, while the fixed section provides stable mounting, resolving the contradiction between ease of manufacture and atomization effectiveness.
2Reliability
If the diameter of the ultrasonic atomization sheet is increased to improve atomization effect, then the atomization effect improves, but the size of the ultrasonic electronic cigarette becomes large
Solution Approach 1:
The invention changes the shape of the piezoelectric substrate from a disc (two-dimensional circular area) to an elongated rectangular shape. This dimensional change allows the oscillating section to extend in length rather than requiring a large diameter, achieving good atomization effect with a more compact overall device size.
3Reliability
If the piezoelectric substrate is made elongated, then the amplitude and atomization effect are improved, but the structural complexity increases
Solution Approach 1:
The elongated piezoelectric substrate is segmented into fixed and oscillating sections, with clear functional differentiation. This segmentation simplifies the overall structure by defining specific roles for each part, reducing structural complexity while maintaining improved atomization effect from the elongated oscillating section.
