Solution Overview
Problem
General aerosol generating apparatuses often carbonize the wick due to excessive heating, which affects the production and quality of aerosol.
Innovation Solution
The aerosol generating apparatus includes a wick with varying absorption rates for the aerosol generating material along its length, and a coil heating element with different winding intervals to optimize heating intensity, preventing wick carbonization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the wick is heated uniformly along its entire length, then the aerosol generating material at the end portions (with high absorption rates) can be effectively vaporized, but the center portion (with low absorption rates) becomes excessively heated and carbonized
Solution Approach 1:
The heating element is designed with non-uniform heating characteristics: it applies strong heating to the end portions of the wick where absorption rates are high, and weak heating to the center portion where absorption rates are low. This local differentiation of heating intensity matches the spatial variation in absorption rates, preventing carbonization while maintaining aerosol generation efficiency
Solution Approach 2:
The heating parameters (temperature distribution along the wick length) are changed to correspond with the absorption rate profile. By adjusting the heating intensity at different positions along the wick, the system optimizes both aerosol production and prevents harmful carbonization
2Productivity
If the heating intensity is increased to enhance aerosol production, then more aerosol generating material is vaporized, but the wick carbonizes due to excessive heating
Solution Approach 1:
The heating element provides differentiated heating intensity at different wick positions: high heating intensity at end portions where material is readily available for vaporization, and low heating intensity at the center portion where material supply is limited. This prevents carbonization and maintains wick durability while ensuring sufficient aerosol production

AI summary
A vaporizer includes a storage storing a liquid aerosol generating material, a wick extending in one direction and absorbing the aerosol generating material through both end portions thereof that are connected to the storage, and a coil surrounding the wick a plurality of times at different winding intervals and heating the aerosol generating material absorbed by the wick, based on an absorption rate profile of the aerosol generating material which changes in the wick along the one direction.
