Solution Overview

Problem

Existing non-combustible aerosol provision devices lack flexibility in configuring articles for different aerosol production profiles and user experience, with limited airflow management and visibility of aerosol-generating material.

Innovation Solution

An article for non-combustible aerosol provision devices featuring an aerosol-generating section surrounded by an outer wrapper with air permeable sections, allowing for different configurations and airflow paths, and visible aerosol-generating material through windows or perforations, enabling varied aerosol production and user identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the outer wrapper is made opaque and sealed, then the aerosol-generating material is protected from contamination, but the user cannot see the material usage and airflow management is limited

Engineering Contradiction:
Improveprotection of aerosol-generating materialVSAvoidairflow management flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The outer wrapper incorporates air permeable sections that allow controlled airflow through the wrapper while maintaining structural integrity. This enables the wrapper to be both protective and breathable, resolving the contradiction between sealing/protection and airflow management.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The outer wrapper is divided into different sections: opaque sealed portions for protection and air permeable sections for airflow. This segmentation allows different parts of the wrapper to serve different functions, simultaneously achieving protection and airflow management.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the outer wrapper is made fully opaque, then the aerosol-generating material is protected, but the user cannot identify material usage status

Engineering Contradiction:
Improveprotection of aerosol-generating materialVSAvoidvisibility of material usage
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The outer wrapper combines opaque and transparent sections, allowing the transparent portions to display material usage status while opaque portions provide protection. This resolves the contradiction between protection and information visibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The outer wrapper may incorporate color-changing or translucent sections that allow visual monitoring of material consumption. Users can see through these sections to determine whether the aerosol-generating material is depleted, maintaining protection while providing information.

Inventive Principle:
Principle #32Color changes

3Device complexity

If a single aerosol-generating material is used, then the device structure is simple, but the user experience lacks variety

Engineering Contradiction:
Improvestructure of articleVSAvoidaerosol production profiles
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The aerosol-generating material is divided into multiple sections with different compositions, flavors, or properties. Each section can produce different aerosol profiles, enabling variety while maintaining a single integrated article structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different sections of the aerosol-generating material have different local properties (flavors, densities, active substances). This allows the article to provide varied aerosol experiences without requiring multiple separate devices or complex mechanisms.

Inventive Principle:
Principle #3Local quality

4Adaptability or versatility

If air permeable sections are added to the outer wrapper, then airflow management is improved, but the structural integrity of the wrapper is compromised

Engineering Contradiction:
Improveairflow managementVSAvoidstructural integrity of outer wrapper
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The air permeable sections use porous materials that maintain structural strength while allowing airflow. The porous structure provides both mechanical integrity and breathability, resolving the contradiction between strength and airflow management.

Inventive Principle:
Principle #31Porous materials

Solution Approach 2:

The outer wrapper is segmented into air permeable and air impermeable sections. The impermeable sections provide structural strength and protection, while the permeable sections enable airflow. This segmentation allows the wrapper to simultaneously achieve strength and airflow management.

Inventive Principle:
Principle #1Segmentation
