Moisturizer-Impregnated Pouch for Aerosol Generating Article
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heating-type aerosol generating devices face challenges in accommodating a sufficient amount of tobacco material, requiring a process of accommodation and cutting, which is inconvenient, and generate insufficient smoke due to low moisture content in the tobacco material.
Innovation Solution
An aerosol generating article with a pouch impregnated with a moisturizer, ranging from 10 to 30 parts by weight relative to 100 parts by weight of the tobacco element, to enhance smoke generation when heated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If tobacco material is accommodated in the accommodation portion and heated, then aerosol is generated, but the amount of smoke is insufficient due to low moisture content
Solution Approach 1:
A pouch made of porous material is introduced as an intermediary between the heating element and the tobacco material. The pouch is impregnated with moisturizer that migrates to the tobacco material during heating, providing the necessary moisture to enhance smoke generation without interfering with the aerosol generation process
Solution Approach 2:
The physical and chemical parameters of the pouch material are specifically designed: it is made of porous material with controlled pore structure to allow moisture migration, and is impregnated with moisturizer at specific concentrations. These parameter changes enable the pouch to transform from a simple container to an active moisture delivery system
2Ease of operation
If tobacco material is accommodated in the accommodation portion, then aerosol can be generated, but the process is inconvenient due to requiring accommodation and cutting steps
Solution Approach 1:
The pouch containing the tobacco material is integrated directly into the accommodation portion, merging the container and the heating chamber into a single unit. This eliminates the need for separate accommodation and cutting steps, as the pouch itself serves as both the container and the heating substrate
Solution Approach 2:
The pouch is designed to be self-contained with the tobacco material already prepared and positioned inside. When placed in the accommodation portion, the system automatically heats the pouch, which in turn heats the tobacco material and generates aerosol, eliminating the need for manual intervention in the heating process
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
The solution provides improved smoking convenience and a sufficient amount of smoke, enhancing user satisfaction while maintaining hygiene through a mouthpiece attached to the pouch.
Implementation Method 1
a heater configured to heat the aerosol generating article accommodated in the accommodation portion
Implementation Method 2
the pouch is made of a porous material and is impregnated with a moisturizer
