Cigarette Filter Opacity via Segmented Material Paper and Ventilation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cigarettes with black absorbents in the filter portion face issues with opacity, as the black absorbents are visible through the tipping paper, and increasing the tipping paper's opacity leads to reduced rigidity and bonding force, causing wrinkles and breakage, while achieving high opacity is difficult without distorting the filter's roundness.
Innovation Solution
A cigarette design with a filter portion containing black absorbents, where the material paper around the filter sections has an opacity of 78% or more, and ventilation holes in the tipping paper on sections without black absorbents, allowing for high outward opacity of 92% or more without compromising rigidity or ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the opacity of the tipping paper is increased to make black absorbents invisible, then the outward appearance is improved, but the rigidity and bonding force of the tipping paper decrease, causing wrinkles and breakage
Solution Approach 1:
The filter portion is divided into multiple filter sections, with at least one section containing black absorbents and other sections not containing black absorbents. This segmentation allows different parts of the filter to have different functional requirements, enabling the tipping paper to maintain appropriate opacity without excessive filler while still achieving the desired white clean appearance.
Solution Approach 2:
Ventilation holes are selectively formed in the tipping paper at positions corresponding to filter sections that do not contain black absorbents. This local modification allows those specific areas to maintain higher opacity while other areas with black absorbents can have different ventilation characteristics, resolving the contradiction between overall opacity and local structural integrity.
2Illumination intensity
If the tipping paper is made thicker to increase opacity without increasing filler, then opacity is improved, but the difference between inner and outer circumferential lengths increases, distorting the filter's roundness and generating wrinkles
Solution Approach 1:
Instead of uniformly increasing the thickness of the tipping paper, the invention changes the opacity parameter by using conventional tipping paper with appropriate thickness and instead achieves high outward opacity (92% or more) through the combination of high-opacity material paper (78% or more) around filter sections containing black absorbents and selective ventilation hole formation.
3Object-affected harmful factors
If more black absorbents are used to achieve milder smoking taste, then the smoking taste is improved, but the visibility of black absorbents through the filter portion increases, compromising the white clean impression
Solution Approach 1:
The material paper serving as an intermediary layer between the black absorbents and the external environment is enhanced with high opacity (78% or more). This intermediary effectively blocks the view of black absorbents while still allowing the filter to function, thus maintaining the white clean appearance even when black absorbents are present in the filter portion.
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 design achieves a high outward opacity of the filter portion, making black absorbents difficult to see, maintaining sufficient ventilation, and preventing wrinkles, while using conventional tipping paper with appropriate rigidity and thickness, thus providing a white clean impression.
Implementation Method 1
the material paper winding around the filter section containing the black absorbents has opacity of 78% or more
Implementation Method 2
the tipping paper has ventilation holes opened in advance in its part positioned on the filter section containing no black absorbents
