Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the spray plate vibrates under the driving of the vibrating element for atomization, then the atomization function is achieved, but the vibration area increases causing spray plate fatigue and reduced service life
Solution Approach 1:
The invention introduces a limiting ring that segments the spray plate's vibration area, confining it to a specific circular region. This prevents the entire spray plate from vibrating, thereby reducing fatigue in non-vibrating areas and extending service life while maintaining effective atomization coverage
Solution Approach 2:
The limiting ring creates a localized vibration zone with specific geometric constraints. By defining a precise vibration area through the limiting ring's inner diameter, the spray plate exhibits different mechanical behaviors in different zones: the central area vibrates for atomization while the peripheral area remains stationary, preserving structural integrity
2Productivity
If the entire spray plate vibrates to atomize liquid, then atomization coverage is improved, but the load on spray plate increases reducing atomization efficiency
Solution Approach 1:
The limiting ring segments the spray plate into a vibrating zone and a non-vibrating support zone. This segmentation allows the vibration energy to be concentrated where needed for atomization while avoiding unnecessary load on the entire spray plate structure, thereby improving atomization efficiency
Solution Approach 2:
Instead of vibrating the entire spray plate area, the invention applies partial action by limiting vibration to only the necessary central region. This reduces unnecessary mechanical load while providing sufficient atomization coverage through optimized vibration concentration in the active zone
3Quantity of substance
If piezoelectric material vibrates to push liquid through spray holes, then droplet formation is achieved, but greater energy consumption is required compared to spray plate vibration
Solution Approach 1:
The invention uses the spray plate as an intermediary between the piezoelectric vibrating element and the liquid. The piezoelectric element generates vibration that is transmitted through the spray plate to atomize the liquid. This intermediary approach allows efficient energy transfer and droplet formation with lower energy consumption compared to direct piezoelectric pushing
