Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes suffer from uneven atomization due to the heating wire only heating liquid close to it, leading to poor atomization of liquid farther away, resulting in uneven particle sizes and reduced taste.
Innovation Solution
An atomizing element with a porous body and a porous heating film having micropores enhances liquid contact area and uniform heating, ensuring consistent atomization across the liquid, preventing large atomized particles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a spiral resistance wire is used as the heating element, then the heating speed is fast, but the atomization effect is uneven due to temperature drop with distance
Solution Approach 1:
The patent employs a porous heating film instead of a conventional spiral resistance wire. The porous structure increases the surface area for liquid contact and distributes heat more uniformly across the heating surface, eliminating the temperature gradient that occurs in spiral wires where temperature drops with distance from the heat source. This maintains fast heating while achieving uniform atomization.
Solution Approach 2:
The heating element is constructed as a composite structure combining a porous substrate with heating material, creating a porous heating film. This composite design allows the heating element to simultaneously provide rapid heat generation and uniform heat distribution across its surface, resolving the contradiction between heating speed and atomization uniformity.
2Area of stationary object
If the heating wire distance increases, then more liquid can be heated, but the temperature drops greatly resulting in poor atomization
Solution Approach 1:
The porous heating film provides a large surface area for liquid contact while maintaining uniform temperature distribution. The porous structure allows liquid to penetrate and contact the heating surface throughout the entire area, ensuring that even distant regions receive sufficient heat for effective atomization without significant temperature drop.

Function Achieved in This Case
The solution improves the atomization effect by uniformly heating the liquid, resulting in improved taste and consistent particle sizes, enhancing the overall smoking experience.
Implementation Method 1
a porous heating film formed on the atomizing surface... the plurality of micropores on the porous heating film can increase a contact area for the liquid, thus enhancing an atomizing effect
Implementation Method 2
the porous heating film can further enable the porous body to be heated uniformly, therefore the temperature of the porous body evenly increases at all part
Implementation Method 3
a porous body comprising an atomizing surface and a liquid absorbing surface... The porous body of the aforementioned atomizing element can block the liquid while ensure the liquid guiding effect
Implementation Method 4
When activated, the resistance wire quickly heats up thus turning the liquid absorbed by the wicking material into a vapor... the atomized liquid can be exhausted from the porous body
