Innovation Solution
A heating system with distributed capillary action and surface tension forces in multiple supply channels, combined with electrical heating elements, provides a two-stage heating process, preheating the substance in the first zone and full vaporization in a second zone, optimizing energy use and aerosol delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single heating zone is used for vaporization, then the device structure is simple, but the energy consumption is high and vapor generation efficiency is low
Solution Approach 1:
The heating system is divided into two distinct heating zones: a first heating zone with a first heating element and a second heating zone with a second heating element. This segmentation allows different portions of the liquid to be heated at different temperatures, improving overall energy efficiency and vapor generation effectiveness.
Solution Approach 2:
The first heating zone performs preliminary heating of the liquid before it reaches the second heating zone. This preheating action reduces the energy required in the second zone to achieve full vaporization, thereby improving overall energy efficiency and reducing total energy consumption.
2Productivity
If heating is performed in a single zone, then the device complexity is low, but the aerosol delivery efficiency is insufficient
Solution Approach 1:
The heating system is divided into two distinct heating zones: a first heating zone with a first heating element and a second heating zone with a second heating element. This segmentation allows different portions of the liquid to be heated at different temperatures, improving overall energy efficiency and vapor generation effectiveness.
Solution Approach 2:
Different regions of the heating system are assigned different thermal characteristics. The first heating zone provides preliminary heating at a lower temperature, while the second heating zone completes vaporization at a higher temperature. This local differentiation of heating quality optimizes both aerosol delivery efficiency and energy utilization.
