Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing smoke filters fail to effectively filter toxicants from cigarette smoke while minimizing obstruction to airflow, as they do not utilize a radially extending panel design aligned with smoke flow.

Innovation Solution

A tube with radially extending panels containing filtering material, such as activated carbon, is integrated into a smoking implement, allowing smoke to flow parallel to the central axis while capturing toxicants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional smoke filter design is used, then the filter can be manufactured with simple structure, but the filtration efficiency is insufficient and airflow is blocked

Engineering Contradiction:

Improvefiltration efficiencyVSAvoidfilter structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The filter is divided into multiple panels that are coupled together and fan out radially from a central axis, creating multiple filtration zones that work simultaneously to improve overall filtration efficiency without requiring a single complex filtration medium

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The filter transitions from a traditional linear or cylindrical structure to a radial three-dimensional configuration where panels extend outward from a central axis, allowing smoke to be captured from multiple directions and increasing the effective filtration surface area

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If a filter blocks smoke flow to capture toxicants, then filtration is improved, but the smoking experience is degraded due to reduced airflow

Engineering Contradiction:

Improvetoxicant removalVSAvoidsmoking experience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The filter panels are positioned and configured to provide localized filtration at specific flow paths, allowing toxicants to be captured where smoke density is highest while maintaining open airflow channels that preserve the smoking experience

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The radial panel configuration allows the filter to adapt to the dynamic flow patterns of smoke, with panels positioned to intercept toxicants based on the natural trajectory and diffusion of smoke particles rather than creating a static blocking barrier

Inventive Principle:

Principle #15Dynamics

AI summary

A smoke filtering apparatus for filtering toxicants from cigarette smoke includes a tube sized and configured to insert into a smoking implement. The tube has a pair of ends, each of which is air permeable such that the tube is configured to permit air through the tube via the pair of ends. A filter is mounted within the tube. The filter comprises a plurality of panels which are coupled to each other at a central axis of the filter. The panels extend radially away from the central axis. Each panel comprises a filtering material configured to attract toxicants from smoke.
