Flavor Inhalation Paper Filter for Balanced Aerosol Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Paper filters used in flavor inhalation articles reduce smoking flavor delivery efficiency compared to filters using fibers like cellulose acetate.
Innovation Solution
A flavor inhalation article design featuring a paper filter with a sheet member forming a gap in the longitudinal direction and a low filtration member with lower filtration rate, positioned downstream, enhances flavor delivery by adjusting airflow resistance and incorporating an aerosol modifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a paper filter is used for aerosol filtration, then the filtration ability is improved, but the smoking flavor delivery efficiency is reduced
Solution Approach 1:
The filter part is segmented into multiple functional zones: a paper filter section for aerosol filtration and a low filtration member section for flavor delivery. This segmentation allows each section to perform its specific function optimally without compromising the other.
Solution Approach 2:
Different sections of the filter part have different filtration properties. The paper filter section has high filtration ability while the low filtration member section has lower filtration rate, creating local quality variations that simultaneously achieve both aerosol filtration and flavor delivery.
2Reliability
If a paper filter with high filtration rate is used, then aerosol filtration is improved, but airflow resistance increases
Solution Approach 1:
The filter part is divided into sections with different airflow resistance characteristics. The paper filter section provides filtration while the low filtration member section reduces overall airflow resistance, creating a balanced system.
Solution Approach 2:
The filtration rate parameter is varied along the longitudinal direction of the filter part, transitioning from high filtration rate in the paper filter section to low filtration rate in the low filtration member section, optimizing both filtration and airflow.
