Aerosol-Forming Rod Composition Using Slurry and Paper-Making Sheets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional reconstituted tobacco sheets for heating-type aerosol-generating articles lack versatility in compensating for disadvantages such as filling power, combustion rate, and taste, as they are typically made from a single type of sheet manufactured by a single process.
Innovation Solution
A method and apparatus that utilize the sheet-specific properties of aerosol-forming rod manufacturing processes, such as slurry, paper-making, or extrusion, by mixing two or more types of reconstituted tobacco sheets with different properties or components to control physical properties and tastes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single type of reconstituted tobacco sheet is used, then the manufacturing process is simple, but the filling power and combustion characteristics are insufficient
Solution Approach 1:
The patent applies composite materials by combining reconstituted tobacco sheets from different manufacturing processes (slurry process and paper-making process) to create a mixed tobacco rod. The slurry process provides good combustion characteristics while the paper-making process contributes high filling power, achieving synergistic effects that neither single process can achieve alone.
Solution Approach 2:
The patent applies local quality by using different reconstituted tobacco sheets in different proportions or distributions within the tobacco rod. By controlling the mixing ratio and spatial distribution of sheets from different processes, the patent optimizes local combustion characteristics and filling power to achieve overall performance improvement.
2Ease of manufacture
If a single type of reconstituted tobacco sheet is used, then the manufacturing cost is low, but the taste quality is limited
Solution Approach 1:
The patent combines reconstituted tobacco sheets from different manufacturing processes to create a composite tobacco material that delivers superior taste quality. The slurry process sheets provide good combustion and flavor release, while paper-making process sheets contribute to overall taste balance, creating a synergistic effect that enhances overall taste quality beyond what single-process sheets can achieve.
3Quantity of substance
If reconstituted tobacco sheets from different processes are mixed, then the physical properties and taste are improved, but the manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the tobacco rod into sections or layers containing different reconstituted tobacco sheets from different manufacturing processes. This segmentation allows each process type to contribute its strengths while maintaining manageable manufacturing complexity through modular assembly and standardized mixing ratios.
4Speed
If reconstituted tobacco sheets from different processes are mixed, then the combustion characteristics are improved, but the manufacturing process complexity increases
Solution Approach 1:
The patent applies parameter changes by systematically varying the mixing ratio of reconstituted tobacco sheets from different processes to optimize combustion characteristics. By controlling parameters such as the proportion of slurry process sheets (which provide good combustion) versus paper-making process sheets, the patent achieves desired combustion rates while managing manufacturing complexity through parameter optimization rather than process complexity.
