Dual Heating Element Aerosol Device Redundancy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol-generating devices in the related art cannot function normally if only one heating element is damaged, resulting in unused remaining e-liquid.
Innovation Solution
The device incorporates two heating members arranged in the atomization cavity, allowing the aerosol-generating device to continue functioning even if one heating member is damaged, as the other can still atomize the remaining e-liquid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only one heating element is used in the aerosol-generating device, then the device structure is simple, but the device cannot function normally when the heating element is damaged
Solution Approach 1:
The heating system is segmented into multiple independent heating elements (first heating element and second heating element) that can operate independently. Each heating element has its own heating coil and wick structure, allowing one element to function even when another is damaged, thereby improving device reliability without requiring a complete system redesign
2Reliability
If multiple heating elements are arranged in the atomization cavity, then the device can continue functioning when one heating element is damaged, but the device structure becomes more complex
Solution Approach 1:
Multiple heating elements are merged within a single atomization cavity structure, sharing common components such as the liquid storage cavity, atomization cavity, and air passage. The first and second heating elements are positioned side-by-side and both communicate with the same liquid storage cavity, reducing overall structural complexity while maintaining redundancy
3Reliability
If two heating members are mounted in parallel in the atomization cavity, then the remaining e-liquid can be atomized by the other heating member when one is damaged, but the atomization cavity space requirement increases
Solution Approach 1:
The heating elements are arranged in a nested-like configuration where the first and second heating elements are positioned in parallel within the atomization cavity, with their wicks extending into the liquid storage cavity. This compact arrangement allows both heating elements to coexist in a space-efficient manner, minimizing the required atomization cavity volume while maintaining redundancy
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design ensures continuous use of the aerosol-generating device by allowing the remaining e-liquid to be atomized even if one heating member is damaged, without affecting the device's normal operation.
Implementation Method 1
the heating element generates heat to atomize the e-liquid, to form the aerosol for the user to inhale
Implementation Method 2
the heating element generates heat to atomize the e-liquid

AI summary
An aerosol-generating device is provided. The device includes a liquid storage portion, a first heating member, and a second heating member. A liquid storage cavity, a main airway, and at least a part of an atomization cavity are defined in the interior of the liquid storage portion. One end of the main airway is in communication with the atomization cavity, so that an aerosol generated in the atomization cavity can enter the main airway, and the other end of the main airway is in communication with the outside, so that a user can inhale the aerosol in the main airway through the other end of the main airway.
