Aerosol-Generating Sheet Composition for Better Handleability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating sheets using tobacco extracts require concentration to achieve a manageable composition, and simply adjusting moisture does not result in a sheet that is easy to handle.
Innovation Solution
The composition of the aerosol-generating sheet is formulated with 15 to 50% tobacco extract, 10 to 60% aerosol source, and a total of 23 to 50% non-wood fiber and binder, with citrus fiber and carboxyalkyl cellulose or guar gum as preferred components, maintaining a water:non-water ingredient ratio of 2 to 10:1.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a tobacco extract is used as the tobacco-derived material in aerosol-generating sheets, then the sheet can be produced without concentrating the composition, but the sheet becomes difficult to handle due to improper moisture concentration
Solution Approach 1:
The patent applies parameter changes by optimizing the moisture concentration to a specific range of 10-60% by weight, and setting the total amount of non-wood fiber and binder to 23-50% by weight. These parameter adjustments transform the sheet properties to achieve both easy manufacture and good handleability, resolving the contradiction between production simplicity and operational ease.
2Ease of operation
If the moisture concentration is simply adjusted to improve sheet handleability, then the production process remains simple, but a sheet that is easy to handle cannot be obtained
Solution Approach 1:
The patent uses composite materials by combining non-wood fiber and binder in a specific total amount of 23-50% by weight. This composite approach provides synergistic effects where the non-wood fiber contributes to sheet structure and the binder ensures proper adhesion, achieving precise composition control while maintaining manufacturing simplicity and improving sheet handleability.
3Ease of operation
If the total amount of non-wood fiber and binder is set within a certain range, then the sheet becomes easy to handle, but the composition formulation becomes more complex
Solution Approach 1:
The patent resolves the contradiction by establishing a specific parameter range for the total amount of non-wood fiber and binder (23-50% by weight). This parameter optimization simplifies the formulation complexity while achieving the desired sheet handleability, as the defined range provides clear manufacturing guidelines without requiring overly complex composition design.
