Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smoking alternatives that heat tobacco or aerosol-generating materials do not effectively replicate the smoking experience, as they lack efficient aerosol generation mechanisms that mimic combustion without burning the material.
Innovation Solution
An aerosol generating device with a tapered heating element that protrudes into a receptacle, capable of heating aerosol-generating material to generate an aerosol, featuring a peripheral surface that is tapered along its length, and an air outlet to supply air to the heating zone, allowing for progressive heating and efficient aerosol production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional heating element is used in heating devices, then the device can heat aerosol-generating material, but it does not effectively replicate the smoking experience due to inefficient aerosol generation
Solution Approach 1:
The heating element's geometric parameters are changed by introducing a tapered peripheral surface instead of a conventional uniform cylindrical shape. This parameter modification optimizes heat distribution and aerosol generation efficiency, allowing the device to effectively replicate the smoking experience while maintaining reliable heating function.
2Productivity
If heating is applied to aerosol-generating material, then compounds are released, but the process does not efficiently generate aerosol without burning the material
Solution Approach 1:
The heating element exhibits local quality variation through its tapered peripheral surface, where different radial positions provide different heating characteristics. This localized heating approach enables efficient aerosol generation in specific zones while maintaining lower overall temperatures that prevent combustion, thus achieving high productivity without harmful burning effects.
