Segmented Cigarette Filter with Capsule and Shaping Paper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Capsule filter cigarettes face issues where the content liquid from the capsule permeates through the tipping paper and wrapping paper, causing adherence to fingers and degrading cigarette flammability and taste, and existing solutions either allow air permeability issues or are impractical for manufacturing.
Innovation Solution
A cigarette filter design featuring spaced-out filter materials with a capsule in between, using water- or oil-proof shaping paper and an adhesion device to prevent liquid permeation, where the filter materials are made of non-wrapped acetate and the adhesion device fills gaps between the shaping paper and filter segments, ensuring the content liquid does not reach the wrapping paper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If permeation-preventing material (oil-proof material) is used for shaping paper, then content liquid permeation is prevented, but air permeability is compromised
Solution Approach 1:
The filter is divided into multiple filter segments with cavities between them. The capsule is placed in the cavity rather than being wrapped by the shaping paper, segmenting the liquid containment function from the air permeation function. This allows the shaping paper to maintain air permeability while the capsule cavity structure prevents liquid permeation.
Solution Approach 2:
The capsule containing the liquid flavoring agent is extracted from the wrapping structure and placed independently in the cavity between filter segments. This removes the liquid containment requirement from the shaping paper, allowing the shaping paper to focus on air permeability while the capsule structure handles liquid prevention.
2Object-generated harmful factors
If conventional rolling paper is used, then air permeability is maintained, but content liquid flows through gaps and permeates wrapping paper
Solution Approach 1:
The filter is segmented into multiple sections with the capsule positioned in the cavity between segments. This segmentation creates a structured arrangement where the capsule is contained within the filter segment cavity, preventing liquid from flowing through gaps to reach the wrapping paper while maintaining proper air flow paths.
3Reliability
If impervious material is used to cover capsule, then liquid permeation is prevented, but air permeability and manufacturing practicality are adversely affected
Solution Approach 1:
The filter structure is segmented with cavities formed between filter segments. The capsule is placed in this cavity space rather than being wrapped in impervious material. This segmentation approach provides a simple, practical manufacturing method where the capsule is positioned in the natural cavity formed during filter assembly, eliminating complex wrapping operations while effectively preventing liquid permeation.

Function Achieved in This Case
Effectively prevents the content liquid from permeating to the tipping paper and wrapping paper, improving the quality of capsule filter cigarettes by maintaining flavor and preventing liquid adherence, while ensuring air permeability and practical manufacturing.
Implementation Method 1
shaping paper that covers the filter materials and the capsules, connects the filter materials to each other, and includes permeation-preventing material for preventing the permeation of the content liquid
Implementation Method 2
an adhesion device for adhering the filter materials and the shaping paper to each other in between the filter materials and the shaping paper over a part of or the entire circumference of the filter materials and the shaping paper
