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 further away, resulting in uneven temperature distribution and particle size, which affects taste and quality.

Innovation Solution

An atomizing element with a porous body and porous heating film enhances atomization by increasing contact area and ensuring uniform heating through micropores, preventing liquid leakage, and allowing uniform temperature distribution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a spiral resistance wire is used as the heating element, then the heating element can be simple in structure, but the atomization effect becomes uneven and poor for liquid located away from the heating wire

Engineering Contradiction:
Improveheating element structureVSAvoidatomization uniformity
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The patent applies porous materials by forming a heating layer on the heating element that contains numerous micropores. These micropores allow liquid to penetrate and be heated uniformly throughout the heating layer, ensuring consistent atomization across the entire surface including areas away from the heating wire. The porous structure increases the effective heating surface area and improves liquid distribution.

Inventive Principle:
Principle #31Porous materials

2Area of stationary object

If the heating wire distance increases, then the heating coverage area increases, but the temperature drops greatly resulting in uneven atomizing particles

Engineering Contradiction:
Improveheating coverage areaVSAvoidtemperature uniformity
Core Design Contradiction:
Area of stationary objectVSTemperature

Solution Approach 1:

The patent changes the physical parameters of the heating element by adding a heating layer with controlled porosity (30-80%) and specific micropore dimensions (5-50 micrometers). This layer acts as a thermal distribution medium that maintains temperature uniformity across the heating coverage area, preventing temperature drop at greater distances from the heating wire while expanding the effective heating area.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If only liquid close to the heating wire is heated, then the heating element structure remains simple, but the atomization efficiency decreases

Engineering Contradiction:
Improveheating element structureVSAvoidatomization efficiency
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The heating layer with micropores enables liquid to be drawn into and distributed throughout the entire heating surface area. This porous structure dramatically increases atomization efficiency by providing numerous micropores (increasing contact area) for liquid evaporation, while maintaining a relatively simple overall heating element structure consisting of the heating wire plus the heating layer coating.

Inventive Principle:
Principle #31Porous materials
