Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional cylindrical ceramic atomizer core is used, then the device structure is simple, but e-liquid accumulates and blocks the atomization channel leading to operational failure
Solution Approach 1:
The atomizer core is divided into multiple cylindrical portions with different diameters along the airflow direction. The first cylindrical portion has a smaller outer diameter than the second cylindrical portion, creating segmented zones that control e-liquid distribution and prevent accumulation in the atomization channel.
Solution Approach 2:
The atomizer core employs an asymmetric structure where the first cylindrical portion has a smaller outer diameter than the second cylindrical portion. This asymmetric design creates different e-liquid absorption and vaporization characteristics in different zones, preventing e-liquid accumulation and blockage while maintaining structural functionality.
2Duration of action of stationary object
If the atomizer core structure is simplified, then manufacturing is easier, but e-liquid buildup occurs reducing service life
Solution Approach 1:
The atomizer core is segmented into multiple cylindrical portions with varying diameters, which controls e-liquid flow and vaporization more effectively. This segmentation prevents e-liquid accumulation and extends service life, while each portion can still be manufactured using standard ceramic processing techniques.
Solution Approach 2:
Different portions of the atomizer core have different diameters to create local variations in e-liquid absorption and vaporization efficiency. The first cylindrical portion with smaller diameter provides one type of local quality, while the second cylindrical portion with larger diameter provides another, optimizing overall performance and extending service life.
3Productivity
If e-liquid absorption is increased, then vapor generation is improved, but blockage in the atomization channel occurs
Solution Approach 1:
The segmented structure with different cylindrical portions creates zones with different e-liquid absorption rates. This segmentation allows efficient vapor generation in the second cylindrical portion while the first cylindrical portion with smaller diameter prevents excessive e-liquid accumulation that would cause blockage.
Solution Approach 2:
Different portions of the atomizer core have different diameters to create local variations in e-liquid absorption and vaporization efficiency. This local quality differentiation enables high vapor generation where needed while preventing blockage in other zones.

The improved design reduces blockages, prolongs the service life of the electronic cigarette device, enhances e-liquid usage efficiency, and simplifies manufacturing, assembly, adjustment, and maintenance processes.
Implementation Method 1
a microporous ceramic structure to reduce e-liquid buildup
Implementation Method 2
the generated airflow will trigger an airflow sensor, and thereby activate the heating element of the atomizer. The electric heating element, disposed within an atomization channel of the atomizer core, starts to heat the e-liquid, and generate aerosol or vapor
Implementation Method 3
the e-liquid 400 at the bottom diffuses from bottom to top due to a diffusion effect

AI summary
An atomization core provides a core body having a central channel, a first cylindrical portion having an outer diameter, and a second cylindrical portion having an outer diameter. The central channel extends through the first and second cylindrical portions, and the first cylindrical portion, the second cylindrical portion, and the central channel are aligned about a central axis. The outer diameter of the second portion is larger than the outer diameter of the first portion.
