Aerosol-Generating Material Using Guar Gum and Starch Binders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-combustible aerosol provision systems face challenges in generating an inhalable aerosol with desirable sensory characteristics when using cut rag tobacco blends, as these blends are unsuitable for high aerosol-former material loading and replacement with reconstituted tobacco can result in undesirable sensory traits.
Innovation Solution
An aerosol-generating material comprising aerosol-former material, guar gum as a first binder, starch or modified starch as a second binder, and filler, which is formulated to have a high aerosol-former content and suitable area density, allowing for the generation of an acceptable aerosol when heated, and can be combined with tobacco material to form an aerosol-generating composition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If cut rag tobacco blends are used in non-combustible aerosol provision systems, then the material structure is simple and easy to manufacture, but the aerosol-former material loading is limited and sensory characteristics are undesirable
Solution Approach 1:
The patent applies composite materials by combining cut rag tobacco with reconstituted tobacco in a specific blend ratio (at least 20% reconstituted tobacco by weight). This composite approach allows the material to achieve both structural integrity for easy manufacture and sufficient aerosol-former loading capacity, as the reconstituted tobacco component provides the necessary binding and aerosol-generation properties that pure cut rag tobacco lacks.
2Quantity of substance
If reconstituted tobacco is used to replace cut rag tobacco, then aerosol-former material loading increases, but undesirable sensory traits appear
Solution Approach 1:
The patent applies local quality by specifying that reconstituted tobacco should constitute at least 20% but not exceed a certain proportion of the total tobacco material. This controlled local incorporation of reconstituted tobacco in specific quantities allows the blend to achieve sufficient aerosol-former loading while limiting the negative sensory effects that would result from excessive reconstituted tobacco content. The specific percentage range optimizes the balance between aerosol generation and sensory quality.
3Quantity of substance
If high aerosol-former content is achieved, then desirable aerosol generation is possible, but the area density and material composition become difficult to control
Solution Approach 1:
The patent applies parameter changes by establishing specific quantitative parameters for the tobacco blend composition (at least 20% reconstituted tobacco by weight) and controlling the area density within a defined range. By setting these specific parameter thresholds and ranges, the patent enables manufacturers to achieve high aerosol-former content while maintaining precise control over area density and other physical properties, ensuring consistent aerosol generation performance.
