Cigarette Filter with Green Tea Extract for Smoke Odor Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cigarette smoke lingers on smokers' hands, causing discomfort and inconvenience, as conventional filters are ineffective in significantly reducing the intensity of the smoke smell.
Innovation Solution
A cigarette filter incorporating a green tea extract containing catechin, citric acid, glycerol, or tannic acid is used to reduce the smell of cigarette smoke, with these materials being added to the filter unit or wrapping paper via coating, dipping, or mixing with a liquid, and the filter unit is coupled to a tobacco shred with a tipping paper to enhance smoke filtration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional filter is used to filter cigarette smoke, then smoke filtration is achieved, but cigarette smoke smell lingers on hands causing discomfort
Solution Approach 1:
The patent introduces an intermediary substance (green tea extract containing catechin, citric acid, glycerol, or tannic acid) applied to the filter wrapping paper or filter unit. This intermediary material acts as a mediator between the cigarette smoke and the user's hands, chemically interacting with smoke components (nicotine, pyridine, 3-ethyl pyridine) to reduce their adherence to hands and thereby eliminating the lingering smell problem
Solution Approach 2:
The patent employs composite materials by combining multiple functional substances (green tea extract, catechin, citric acid, glycerol, tannic acid) with the filter structure. This composite approach creates a multi-functional filter that not only filters smoke particles but also chemically neutralizes odor-causing compounds, thereby resolving the contradiction between filtration and smell removal
2Object-affected harmful factors
If green tea extract and smell removing materials are added to the filter, then cigarette smoke smell on hands is reduced, but filter manufacturing complexity increases
Solution Approach 1:
The patent applies the preliminary action principle by pre-coating or pre-soaking the filter wrapping paper or filter unit with green tea extract and smell-removing materials during the manufacturing process. This preliminary treatment ensures that the functional materials are already in place before the filter is assembled and used, simplifying the overall manufacturing process while achieving the desired smell reduction effect
Solution Approach 2:
The patent utilizes parameter changes by optimizing the concentration and composition of green tea extract and associated materials (catechin, citric acid, glycerol, tannic acid) applied to the filter. By carefully controlling these material parameters, the patent achieves effective smell reduction while maintaining manageable manufacturing complexity through standardized coating or soaking processes
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 filter significantly lowers the intensity of cigarette smoke smell lingering on hands by reducing nicotine, pyridine, and 3-ethyl pyridine levels by approximately 30%, 13%, and 40% respectively, compared to conventional tobacco filters, thereby improving user experience.
Implementation Method 1
a green tea extract containing catechin and citric acid, glycerol or tannic acid are added to a cigarette filter to remove a smell from cigarette smoke
Implementation Method 2
The cigarette smoke smell removing material may include any one or a mixture of catechin, citric acid, glycerol, tannic acid or β-cyclodextrin

AI summary
The filter using technology for reducing the smell of tobacco smoke on hands, according to one embodiment of the present invention, comprises: a filter unit for filtering tobacco smoke, the filter unit being coupled to a tobacco shred; and filter-wrapping paper for wrapping the filter unit. The filter unit or the filter-wrapping paper may contain a material for reducing the smell of tobacco smoke. According to the embodiment of the present invention, green tea extracts containing catechin or other materials for reducing the smell of tobacco smoke, e.g. citric acids, glycerols, tannic acids and the like can be added to a tobacco filter to remove the smell from tobacco smoke generated during smoking, thus significantly lowering the strength of the smell of tobacco smoke on the hands of a smoker as compared to conventional tobacco filters.
