Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nebulization structures face issues with metal nebulization plates experiencing fatigue and embrittlement at high frequency oscillations, while polymer plates lack sufficient rigidity to effectively transmit vibration energy, leading to inefficient nebulization due to inadequate energy transmission to the center of the nebulization plate.
Innovation Solution
A nebulization structure comprising a piezoelectric annular driving element, a circular disc-shaped structure plate with radially arranged through holes and ribs, and a nebulization plate made of polymer or metal materials, where the nebulization plate is clamped between the driving element and structure plate, enhancing energy transmission and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the nebulization plate is made of metal material, then the vibration energy transmission efficiency is improved, but the plate becomes fatigued and embrittled after long-time high frequency oscillation
Solution Approach 1:
The patent uses a metal nebulization plate combined with a polymer protective layer, creating a composite structure that leverages the high vibration transmission efficiency of metal while protecting it from fatigue and embrittlement through the polymer coating, thus resolving the contradiction between energy transmission and durability
2Reliability
If the nebulization plate is made of polymer material, then the plate durability is improved, but the rigidity becomes insufficient and vibration energy transmission efficiency decreases
Solution Approach 1:
The patent creates a composite structure where a polymer layer is applied over a metal nebulization plate, allowing the polymer to provide durability and corrosion resistance while the underlying metal ensures sufficient rigidity and vibration energy transmission efficiency
3Ease of manufacture
If the structure annular plate is designed as an annular structure, then the manufacturing simplicity is improved, but the vibration energy transmission to the center position of the nebulization plate becomes insufficient
Solution Approach 1:
The patent segments the structure plate into multiple functional zones including radial ribs that divide and direct vibration energy transmission paths, ensuring that energy from the annular piezoelectric element is effectively distributed to the center position of the nebulization plate while maintaining manufacturing simplicity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves effective vibration energy transmission and improved nebulization efficiency by stabilizing the nebulization plate and ensuring efficient energy distribution across the plate, preventing fatigue and embrittlement, and enhancing chemical resistance.
Implementation Method 1
When an electric field is applied to the piezoelectric annular plate 11 from the lateral side of the piezoelectric annular plate 11, the piezoelectric annular plate 11 produces a transverse contraction and induces the deformation of the nebulization plate 12
Implementation Method 2
the structure annular plate 13 is provided for fixing the nebulization plate 12 and oscillated by the piezoelectric annular plate 11 to vibrate together with the piezoelectric annular plate 11

AI summary
A nebulization structure includes a driving element, a structure plate and a nebulization plate. The structure plate is installed on a side of the driving element, and the structure plate is substantially in a circular disc shape and has a plurality of through holes, and at least one rib is formed between adjacent through holes to define a water guide passage. The nebulization plate is clamped between the driving element and the structure plate and made of a polymer material to overcome the problems of having easy metal fatigue and embrittlement of the nebulization plate made of metal, and being corroded by corrosive liquids.
