Flavor Inhalation Paper Filter with Hollow Member Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter designs for flavor inhalation articles face challenges in balancing delivery efficiency and ease of manufacture, particularly when incorporating an elongate hollow member in a paper filter, as it is difficult to position the hollow member correctly due to manufacturing constraints.
Innovation Solution
A filter portion for flavor inhalation articles is designed with a paper filter filled with a sheet member to form voids along the longitudinal direction, incorporating a hollow member with one end within a predetermined distance from the filter end, and using a paper tube or spiral paper tube for the hollow member, ensuring a lower filtration rate and balanced airflow resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a through-sized hollow member is arranged in the paper filter to adjust flavor and hardness, then delivery efficiency is improved, but manufacturing difficulty increases
Solution Approach 1:
The hollow member is divided into multiple sections along its length, with different sections having different filtration rates. The first section (near the mouthend) has a lower filtration rate to maintain delivery efficiency, while the second section (near the tailend) has a higher filtration rate to remove aerosol. This segmentation allows the hollow member to provide both delivery efficiency and aerosol filtration without requiring a through-sized configuration that is difficult to manufacture.
Solution Approach 2:
Different portions of the hollow member are given different filtration properties. The first portion has a lower filtration rate optimized for delivering aerosol to the user, while the second portion has a higher filtration rate optimized for filtering aerosol. This local differentiation of properties allows each section to perform its specific function optimally, resolving the contradiction between delivery efficiency and manufacturing ease.
2Productivity
If the hollow member is positioned within a predetermined distance from the longitudinal end of the filter portion, then delivery efficiency is improved, but manufacturing precision requirements increase
Solution Approach 1:
The hollow member is pre-assembled with the paper filter during the manufacturing process, with its position predetermined and fixed before the filter is fully assembled. The first section of the hollow member is positioned within the paper filter at a specific distance from the mouthend, while the second section extends beyond the paper filter. This preliminary positioning ensures delivery efficiency is maintained while the manufacturing process itself establishes the correct position, reducing the need for additional precision adjustments.
3Productivity
If the hollow member has lower filtration rate than the paper filter, then aerosol delivery is improved, but aerosol filtration capability is reduced
Solution Approach 1:
The hollow member is segmented into two sections with different filtration rates. The first section has a lower filtration rate than the paper filter to maintain aerosol delivery efficiency, while the second section has a higher filtration rate to provide aerosol filtration. This segmentation allows the system to achieve both aerosol delivery and filtration without compromising either function.
Solution Approach 2:
Different sections of the hollow member have different filtration properties tailored to their specific functions. The first section (lower filtration rate) is located where aerosol delivery is prioritized, while the second section (higher filtration rate) is located where aerosol filtration is prioritized. This local quality differentiation resolves the contradiction between delivery and filtration capabilities.
