Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ceramic body with large apertures is used, then E-liquid flow is improved, but E-liquid leakage occurs
Solution Approach 1:
The patent applies local quality by creating different aperture sizes in different regions of the ceramic body. The first aperture region has larger apertures to facilitate E-liquid supply, while the second aperture region has smaller apertures to prevent leakage. This spatial variation in aperture quality allows the system to simultaneously achieve adequate E-liquid flow and prevent unwanted leakage.
2Object-affected harmful factors
If ceramic body with small apertures is used, then E-liquid leakage is prevented, but dry-burning of heating wire occurs
Solution Approach 1:
The patent divides the ceramic body into two aperture regions with different aperture sizes. The first region with larger apertures ensures sufficient E-liquid supply to prevent dry-burning, while the second region with smaller apertures prevents leakage. This local differentiation in aperture quality resolves the contradiction between preventing leakage and ensuring adequate E-liquid supply.
3Device complexity
If heating wire is integrated with ceramic body at 800-900°C, then structure is simplified, but ceramic stability is reduced causing powder loss
Solution Approach 1:
The patent changes the sintering temperature parameter from the conventional 800-900°C to a higher temperature range of 1200-1400°C. This parameter change transforms the ceramic body to achieve full densification and grain recrystallization, significantly improving ceramic stability and eliminating powder loss while maintaining the integrated structure with the heating wire.
4Ease of manufacture
If uniform aperture size is used in ceramic body, then manufacturing is simplified, but atomization efficiency is reduced
Solution Approach 1:
The patent implements local quality by creating two distinct aperture regions with different aperture sizes within the ceramic body. The first region with larger apertures optimizes E-liquid supply, while the second region with smaller apertures enhances atomization efficiency. This localized differentiation in aperture quality improves atomization performance while maintaining reasonable manufacturing feasibility.

AI summary
The present invention provides mainly a self-regulating smart atomizing core and its manufacturing method, and an atomization generating device including said atomizing core. Said atomizing core comprises a main body being consisted of grains (11, 12, 13) and having a first surface and a second surface set oppositely, a heating and atomizing layer is set on the second surface, the main body having open apertures (111, 121, 131) connecting the first surface and the second surface for allowing a liquid to pass through, the sizes of said open apertures among the grains of said main body decrease from the first surface to the second surface in the thickness direction, the first surface is configured, when it is in contact with the liquid, to allow the liquid flows into the apertures among the grains of said main body, pass through these apertures toward the second surface. During the liquid flowing through the main body, because apertures among the grains of the main body decrease from the first surface to the second surface, the flow rate of the liquid toward the second surface gradually increases and the pressure also gradually increases, which allow the liquid to arrive finally at the second surface and to be atomized under high rate and high pressure. The present invention provides also an atomization generating device for electronic cigarette, said atomization generating device may be sheet-type and/or negative-pressure type.
