Crimped Sheet Filler Elements for Uniform Liquid Additive Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing filter materials, such as acetate tow, suffer from uneven distribution of liquid additives, leading to spilling and contamination, which affects the quality and consistency of flavor inhalation articles.
Innovation Solution
A manufacturing device and method that involves crimping the sheet to increase surface area, using a multiple-nozzle addition system to uniformly distribute liquid additives, and forming a gathering rod that is wrapped to create a filler element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a relatively large amount of additive is added to the filter textile, then the flavor production function is enhanced, but the additive becomes unevenly distributed and spills
Solution Approach 1:
The patent divides the additive application into multiple segments by using multiple nozzles arranged in the width direction, allowing controlled distribution of additive across different regions of the sheet to prevent local saturation and spilling
Solution Approach 2:
The patent applies different properties to different regions by creating crimped parts at specific locations on the sheet, which locally increase absorption capacity in those areas while maintaining normal properties elsewhere, enabling uniform overall distribution
2Ease of manufacture
If a flat sheet is used for the filter material, then the manufacturing process is simple, but the additive distribution becomes uneven
Solution Approach 1:
The patent creates crimped parts at specific locations on the sheet to locally increase surface area and absorption capacity, allowing the rest of the sheet to remain flat and simple while achieving uniform overall additive distribution
Solution Approach 2:
The patent transforms the two-dimensional flat sheet into a three-dimensional crimped structure by forming ridges and grooves, which increases the effective surface area for additive absorption without complicating the manufacturing process
3Adaptability or versatility
If the additive is dropped onto the upper surface of the filter textile, then the flavoring function is achieved, but the spilled additive contaminates equipment
Solution Approach 1:
The patent introduces crimped parts as an intermediary structure that mediates between the additive and the filter textile, providing increased absorption capacity that prevents additive from spilling onto equipment while maintaining flavor production function
Solution Approach 2:
The patent segments the additive application process using multiple nozzles positioned at different locations, ensuring additive is distributed across the entire sheet surface and absorbed uniformly, preventing spillage onto equipment
4Reliability
If acetate tow is used as the filter material, then the filtering function is provided, but the additive cannot be uniformly added
Solution Approach 1:
The patent modifies the acetate tow by creating crimped parts at specific locations, which locally increase absorption capacity to compensate for the inherent limitations of acetate tow in uniform additive distribution, while maintaining the filtering function
Solution Approach 2:
The patent transforms the two-dimensional acetate tow into a three-dimensional crimped structure, increasing the effective surface area for additive absorption and enabling uniform additive distribution while preserving the filtering function
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
Enables uniform addition of liquid additives without spilling, improving the quality and consistency of flavor inhalation articles by reducing equipment contamination and ensuring consistent smoke taste.
Implementation Method 1
The sheet processing section forms a crimped part in the sheet during the conveying process of the sheet, the crimped part being arranged in the width direction and extending in the longitudinal direction
Implementation Method 2
The addition section has a feed portion that continuously feeds the additive dropwise onto the upper surface of the sheet, having the crimped part formed therein
Implementation Method 3
a gathering section that forms a gathering rod during a conveying process of the sheet along the conveyance path, the gathering rod being reduced in diameter by gathering the sheet
Implementation Method 4
a wrapping section that wraps the gathering rod, formed at the gathering section, with wrapping paper to form a filler rod
