Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a compression spring or glass fiber tube is used to press the liquid guide element against the atomization surface, then good contact is kept between the liquid guide element and the atomization surface, but the internal design becomes complex and material and assembly costs increase
Solution Approach 1:
The sealing member is designed to perform multiple functions simultaneously: it seals the liquid storage cavity, presses the liquid guide element against the atomization surface to ensure good contact, and provides structural support. By combining these functions into a single component, the patent eliminates the need for separate compression springs or glass fiber tubes, thereby simplifying the internal design and reducing assembly complexity while maintaining reliable contact between the liquid guide element and atomization surface
Solution Approach 2:
The sealing member is designed as a multi-functional component that simultaneously achieves sealing of the liquid storage cavity and mechanical pressing of the liquid guide element against the atomization surface. This universal design allows a single component to fulfill multiple roles that previously required separate parts, reducing overall device complexity and assembly requirements while ensuring consistent contact quality
2Reliability
If a glass fiber tube is used to press the liquid guide element, then good contact is kept, but glass fiber catkins generated can easily cause severe damage to a human body
Solution Approach 1:
The patent replaces the glass fiber tube with a sealing member made from safer, non-shattering materials such as silicone rubber or thermoplastic elastic body. These materials do not generate harmful fibers or catkins that could damage the human body, while still providing the necessary mechanical pressing function to maintain good contact between the liquid guide element and atomization surface
Solution Approach 2:
The patent eliminates the harmful aspect of glass fiber tubes (fiber generation and shattering risk) by using elastomeric materials that are inherently safer. The sealing member made from materials like silicone rubber or thermoplastic elastic body provides the same mechanical function without the harmful side effects, effectively converting a harmful component into a safe one while maintaining contact quality
3Reliability
If a rigid pressing element is used to press the liquid guide element against the atomization surface, then contact is maintained, but the atomization sheet may be damaged during high-frequency oscillation
Solution Approach 1:
The patent changes the material parameters of the pressing element from rigid to elastomeric. The sealing member is made from materials with appropriate elasticity and hardness (such as silicone rubber with Shore A 20-40 or thermoplastic elastic body with Shore D 60-80), allowing it to maintain contact pressure while deforming elastically during high-frequency oscillation, thereby preventing damage to the atomization sheet
Solution Approach 2:
The elastomeric sealing member acts as a cushioning element that absorbs and distributes the mechanical stresses during high-frequency oscillation. The material's elasticity provides a buffering effect that prevents concentrated forces from damaging the atomization sheet, while still maintaining sufficient contact pressure for proper liquid guidance

AI summary
An ultrasonic atomizer (10) and an ultrasonic atomization device (100) are provided. The ultrasonic atomizer (10) includes a housing. The housing is internally provided with: a liquid storage cavity (A); a liquid guide element (102, 103); an ultrasonic atomization sheet (1051), including an atomization surface, where the ultrasonic atomization sheet (1051) is configured to ultrasonically atomize a liquid substrate absorbed by the liquid guide element (102, 103) to generate an aerosol; and a sealing member (104), configured to seal at least a part of the liquid storage cavity (A), where the sealing member (104) is further configured to stay in contact with at least a part of the liquid guide element (102, 103) and abut the at least a part of the liquid guide element (102, 103) against the atomization surface. In the ultrasonic atomizer (10), the sealing member (104) of the liquid storage cavity (A) is utilized to directly abut against the liquid guide element (102, 103), so that the liquid guide element (102, 103) can be in close contact with the atomization surface of the ultrasonic atomization sheet (1051), thereby saving material and assembly costs. In addition, since the sealing member (104) is elastic, the liquid guide element (102, 103) elastically abuts against the atomization surface of the ultrasonic atomization sheet (1051), so that the sealing member (104) and the liquid guide element (102, 103) do not cause damage to the ultrasonic atomization sheet (1051) when the ultrasonic atomization sheet (1051) oscillates at a high frequency.
