Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the ceramic material of the core has a high porosity, then e-liquid absorption capacity is improved, but e-liquid leakage occurs due to too high guide speed
Solution Approach 1:
The atomization core is divided into multiple ceramic layers with different porosity values. The first ceramic layer has a first porosity value optimized for e-liquid absorption, while the second ceramic layer has a second porosity value optimized for controlling e-liquid guide speed. This segmentation allows each layer to perform its specific function without the harmful effects of extreme porosity values.
Solution Approach 2:
Different regions of the atomization core (different ceramic layers) are assigned different porosity values according to their specific functional requirements. The first layer near the e-liquid source has higher porosity for absorption, while the second layer closer to the heating element has lower porosity for controlled delivery, creating local quality optimization throughout the structure.
2Object-generated harmful factors
If the ceramic material of the core has a low porosity, then e-liquid leakage is prevented, but dry burning occurs due to insufficient e-liquid supply
Solution Approach 1:
The atomization core is divided into multiple ceramic layers with different porosity values. The first ceramic layer has a first porosity value optimized for e-liquid absorption and supply reliability, while the second ceramic layer has a second porosity value optimized for preventing e-liquid leakage. This segmentation allows each layer to perform its specific function without the harmful effects of extreme porosity values.

3Device complexity
If a single-layer ceramic structure is used, then device complexity is reduced, but it is difficult to balance e-liquid delivery and vaporization efficiency
Solution Approach 1:
The atomization core is divided into multiple ceramic layers with different porosity values. The first ceramic layer has a first porosity value optimized for e-liquid absorption and delivery, while the second ceramic layer has a second porosity value optimized for vaporization efficiency. This segmentation allows each layer to perform its specific function without the harmful effects of extreme porosity values.

AI summary
An atomization core provides a core body having a central channel, a generally cylindrical, ceramic first layer having an outer diameter and an inner diameter, and a generally cylindrical, ceramic second layer having an outer diameter and an inner diameter. The central channel extends through the first and second layers. The first layer, the second layer, and the central channel are aligned about a central axis, and the inner diameter of the second layer is about equal to the outer diameter of the first layer.
