Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional centrifugal atomization device is used, then the liquid can be atomized into droplets, but the particle diameter of the thrown droplets is not uniform
Solution Approach 1:
The atomization disc is segmented into multiple flow guide grooves that divide the liquid flow into separate paths, each producing uniform droplets. The annular body with teeth further segments the droplet stream, causing them to break into more uniform smaller droplets through differential impact angles and forces.
Solution Approach 2:
The teeth on the annular body act as intermediary elements between the centrifugal atomization disc and the final droplet stream. These teeth mediate the droplet formation process by providing controlled impact surfaces that break up larger droplets into uniform smaller droplets without requiring complex additional atomization mechanisms.
2Productivity
If the particle diameter is reduced to improve atomization, then spraying efficiency increases, but chemical liquid is wasted due to non-uniform distribution
Solution Approach 1:
Different regions of the atomization system are optimized for specific functions: the flow guide grooves on the atomization disc create initial droplet formation, while the teeth on the annular body create secondary breakdown into finer droplets. This local optimization ensures uniform particle size distribution throughout the spray pattern, improving coverage and reducing waste.
Solution Approach 2:
The system changes physical parameters by utilizing the centrifugal force generated by rotation to control droplet size and distribution. The flow guide grooves and teeth are designed with specific geometries that optimize the centrifugal separation and impact forces, producing uniform droplets of controlled size that improve spraying efficiency and reduce chemical liquid waste.
3Volume of moving object
If the space between the annular body and centrifugal atomization disc is reduced, then the structure is more compact, but droplets cannot be completely torn for adequate atomization
Solution Approach 1:
The system resolves the space constraint by utilizing the rotational dimension. The teeth on the annular body are arranged radially outward from the center, creating a three-dimensional atomization zone that allows adequate space for droplet breakdown while maintaining compact radial dimensions. The rotational motion provides the necessary separation distance for effective atomization.

Implementation Method 1
an atomization disc rotates at a high velocity under the action of a motor, and liquid stretches into a thin film on the surface of the rotating atomization disc due to the action of the centrifugal force and moves towards the edge of the disc at a continuously increasing velocity
Implementation Method 2
a plurality of teeth are arranged on the annular body at intervals along the circumferential direction of the annular body; and the teeth are radially arranged outwards on the basis of the center of the annular body
