Solution Overview
Problem
Conventional ceramic heating cores have centralized heating sections that concentrate heat, leading to high local atomization temperatures, poor taste due to e-liquid molecule destruction, limited e-liquid storage, and increased risk of leakage.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the effective heating section is centralized with a short axial height, then the heating efficiency is improved, but the local atomization temperature becomes too high causing e-liquid molecule destruction and poor taste
Solution Approach 1:
The heating wire is designed as multiple helical coils distributed along the axial direction rather than a centralized heating section. This segments the heat generation along the axial direction, distributing the thermal load and preventing excessive local temperature rise while maintaining overall heating efficiency
Solution Approach 2:
The heating wire is configured in a helical shape that extends along the axial dimension of the ceramic body. By utilizing the axial dimension for heat distribution, the patent achieves uniform temperature distribution along the atomization surface without concentrating heat in a small centralized area
2Length of stationary object
If the ceramic body height is limited to 6 mm, then the device size is reduced, but the e-liquid storage amount is limited causing insufficient replenishment and small atomization amount
Solution Approach 1:
The helical heating coils are nested within the ceramic body structure, utilizing the internal volume efficiently. The heating wire is positioned within the ceramic matrix, allowing maximum use of the available space for both heating function and e-liquid storage capacity
Solution Approach 2:
The patent changes the geometric parameters of the heating system by using helical coils with specific pitch and diameter ratios. This configuration increases the surface area of the heating element within the same axial height, improving heat distribution and e-liquid contact efficiency without increasing the overall device size
3Device complexity
If the heating wire is disposed centrally, then the structure is simplified, but the heat distribution is concentrated causing poor taste and increased leakage risk
Solution Approach 1:
The heating wire is configured as an asymmetric helical structure rather than a symmetric centralized coil. The helical shape creates an asymmetric heat distribution pattern that naturally spreads heat along the axial direction, improving uniformity without requiring complex multi-component structures
Solution Approach 2:
The heating wire adopts a curved helical path instead of a straight or simple circular configuration. This curvature allows the heating element to follow the contour of the ceramic body and distribute heat more uniformly across the atomization surface, reducing hot spots and improving both taste quality and leakage prevention
