Flavored Sheet With Activated Carbon For Sustained Fragrance Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flavored sheets for smoking articles face issues with flavor component release due to heat sources during manufacturing, leading to uneven fragrance perception during smoking, and inefficiencies in flavor retention.
Innovation Solution
Incorporating activated carbon into the flavored sheet, which acts as a porous material with strong adsorption power, to retain flavor components and sustain fragrance release even under heat during smoking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a flavored sheet is prepared by drying a solution containing flavor components, then the flavored sheet can be added to smoking articles, but the flavor components are released due to heat sources during drying, resulting in non-uniform fragrance release during smoking
Solution Approach 1:
Activated carbon serves as an intermediary substance that adsorbs flavor components during the drying process, preventing their direct release due to heat. The activated carbon holds the flavor components and releases them gradually during smoking, achieving uniform fragrance distribution and preventing flavor loss during manufacturing.
2Ease of manufacture
If flavor components are added to cigarettes using a transfer jet nozzle system, then specific perfume components can be conveniently added, but a large amount of flavored liquid is discarded around tobacco components, decreasing flavoring efficiency
Solution Approach 1:
The flavored sheet acts as a disposable carrier that consolidates flavor components in a controlled format. Instead of spraying liquid perfume that disperses inefficiently, the pre-formed flavored sheet delivers flavor directly to the cigarette, eliminating wasted flavored liquid and improving flavoring efficiency while maintaining ease of application.
3Device complexity
If existing flavored sheets are used without activated carbon, then the manufacturing process is simpler, but the fragrance is rapidly released in the early stage of smoking and the amount of fragrance is reduced in later stages
Solution Approach 1:
Activated carbon's porous structure provides extensive surface area for adsorbing and gradually releasing flavor components. The porous material controls the release kinetics, allowing sustained fragrance emission throughout the entire smoking duration rather than rapid initial release followed by depletion, thereby extending the effective action duration.
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
The use of activated carbon in the flavored sheet enhances fragrance retention and ensures a more sustained release of flavors during smoking, improving flavoring efficiency and consistency.
Implementation Method 1
applying activated carbon that is a porous material with a large surface area and strong adsorption power
Implementation Method 2
the fragrance may more slowly decrease in a later stage of smoking, so that an effect of sustainedly releasing the fragrance may be shown
