Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing tobacco sheets in heated cigarettes face challenges in achieving uniform nicotine release and smoke quality, particularly in terms of nicotine puff-by-puff uniformity and aroma, which are not adequately addressed by current technologies.
Innovation Solution
A nicotine regulator comprising components A and B, where A is tannic acid, proline, caffeic acid, or pyruvic acid, and B is phosphoric acid or boric acid, combined with an adhesive and gum to encapsulate and modify the tobacco tissue, enhancing nicotine release uniformity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional thick-paste-method or roll-pressing method is used to prepare tobacco sheets, then the sheets can be produced with adjustable chemical composition and combustion properties, but the nicotine puff-by-puff release uniformity is poor and smoke quality is insufficient
Solution Approach 1:
The patent applies preliminary action by pre-modifying tobacco powder with specific acids (citric acid, malic acid, or tartaric acid) before sheet formation. This pre-treatment creates uniform nicotine release characteristics that are maintained throughout the smoking process, resolving the contradiction between manufacturing flexibility and release uniformity.
Solution Approach 2:
The patent changes chemical parameters by introducing specific acids and controlling their concentration (0.5-5% w/w) in the tobacco powder mixture. This parameter modification enables consistent nicotine release across multiple puffs while maintaining the adaptability of chemical composition adjustment inherent in reprocessed tobacco sheets.
2Object-generated harmful factors
If cigarette powder and adhesive are mixed to make thick paste for sheet production, then sheets can be formed with functional roles in reducing tar and harm, but the aroma becomes dull and nicotine release uniformity is insufficient
Solution Approach 1:
The patent introduces acids (citric acid, malic acid, or tartaric acid) as intermediary substances that mediate between the tobacco powder and adhesive matrix. These intermediaries improve nicotine release uniformity and aroma quality without compromising the tar reduction function, effectively resolving the contradiction between harm reduction and product quality reliability.
3Ease of manufacture
If existing tobacco sheet processes are used for heated cigarettes, then production can proceed with current materials and methods, but nicotine release during heating (150°C-300°C) is difficult to control and release uniformity is not ideal
Solution Approach 1:
The patent modifies the chemical composition parameters of the tobacco powder by adding specific acids before sheet formation. This parameter change ensures that during the heating process (150°C-300°C), nicotine is released uniformly across multiple puffs, while maintaining relative simplicity in the manufacturing process.
Applied Scientific Principles

AI summary
A nicotine regulator for improving nicotine puff-by-puff release uniformity of a new tobacco product. The nicotine regulator comprises a component A and a component B, wherein the component A is at least one of tannic acid, proline, caffeic acid and pyruvic acid; and the component B is at least one of phosphoric acid and boric acid. In addition, provided are a thick slurry comprising the nicotine regulator and a preparation method therefor, a thick-slurry-method thin sheet prepared by using the thick slurry, and a new tobacco product comprising the thick-slurry-method thin sheet. In the nicotine regulator, by means of the combined cooperation of the component A and the component B, the release behavior of nicotine in a tobacco tissue can be induced and adjusted, and the nicotine puff-by-puff release uniformity of the new tobacco product can be significantly improved.
