Multi-stage Cigarette Holder Filter with Biomaterial Segmentation

Solution Overview

Problem

Existing disposable filter cigarette holders are costly, complex to prepare, and have poor filter efficiency, particularly for smokers of low and medium consumption, who are economically pressured and face health risks due to inadequate hygiene and high tar/nicotine exposure.

Innovation Solution

A disposable multi-stage cigarette holder filter apparatus is developed, featuring a cylinder structure with a composite filter rod, filter cushion layer, and multi-stage filtration, using biomaterials like wood-based biochar, fiber particles, and activated alumina, along with air inlets and a cooling layer to enhance filtration efficiency and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional disposable cigarette holders are used, then hygiene is improved through disposal, but filter efficiency deteriorates after 70% consumption and cost increases

Engineering Contradiction:

ImprovehygieneVSAvoidfilter efficiency

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The cigarette holder is divided into multiple functional segments: a first filter rod with porous structure for initial filtration, a second filter rod with different porosity for secondary filtration, and a partition wall separating them. This multi-stage segmentation enables sustained high filter efficiency throughout the entire smoking process, addressing the deterioration problem of traditional single-stage filters.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent employs composite material structures with varying porosity levels in different filter rod sections. The first filter rod uses a porous structure while the second uses a different porosity configuration, creating a composite filtration system that maintains effectiveness throughout cigarette consumption, thereby resolving the filter efficiency deterioration issue.

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If reusable cigarette holders are used, then cost is reduced, but hygiene deteriorates due to lack of proper disinfection

Engineering Contradiction:

ImprovecostVSAvoidhygiene

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent designs an affordable disposable cigarette holder using cost-effective materials and a simplified multi-stage filter structure. The low production cost makes disposable use economically acceptable for consumers, while the disposable nature ensures hygiene by eliminating cross-contamination risks associated with reusable holders that lack proper disinfection.

Inventive Principle:

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The cigarette holder is divided into multiple functional segments: a first filter rod with porous structure for initial filtration, a second filter rod with different porosity for secondary filtration, and a partition wall separating them. This multi-stage segmentation enables sustained high filter efficiency throughout the entire smoking process, addressing the deterioration problem of traditional single-stage filters.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements a multi-stage filtration system that provides excessive filtration capacity beyond what a single stage could achieve. By incorporating multiple filter rods with different porosity levels, the system ensures that even after 70% consumption, the remaining filter sections continue to provide effective filtration, thereby maintaining high filter efficiency throughout the cigarette's lifecycle.

Inventive Principle:

Core Design Contradiction:

Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The patent employs composite material structures with varying porosity levels in different filter rod sections. The first filter rod uses a porous structure while the second uses a different porosity configuration, creating a composite filtration system that maintains effectiveness throughout cigarette consumption, thereby resolving the filter efficiency deterioration issue.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The patent utilizes biomaterials with controlled porosity parameters to achieve both cost reduction and consistent filtration performance. By carefully selecting and configuring materials with specific porosity levels in different sections, the invention maintains manufacturing precision while using affordable biomaterials, resolving the contradiction between cost and quality.
