Solution Overview

Problem

Existing non-combustible aerosol provision devices face challenges in efficiently delivering aerosols from multiple types of aerosol generating materials without burning, particularly in ensuring uniform heating and maintaining flavor consistency.

Innovation Solution

The design of an article for non-combustible aerosol provision devices includes spaced and abutting sections of aerosol generating materials, each with optional different compositions, wrapped by a wrapper, and is used with a device featuring separate heating elements to independently heat these sections, allowing for concurrent or sequential aerosol production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple types of aerosol generating materials are used in a single article, then flavor variety and user experience are improved, but heating uniformity and flavor consistency deteriorate due to cold spots and uneven heat distribution

Engineering Contradiction:

Improveflavor varietyVSAvoidheating uniformity

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The article is divided into multiple discrete sections, each containing a different type of aerosol generating material. Each section is independently wrapped and positioned at specific locations along the article's longitudinal axis, allowing separate heating zones to target each material type uniformly without interference from adjacent materials.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different sections of the article are designed with locally optimized properties - each section contains materials tailored for specific flavor profiles and heating requirements. The spacing and positioning of sections are optimized to ensure each material type receives appropriate heat distribution from corresponding heating elements.

Inventive Principle:

Principle #3Local quality

2Productivity

If aerosol generating material sections are placed close together to maximize material density, then productivity and aerosol output are improved, but heat distribution uniformity deteriorates due to cold spots between sections

Engineering Contradiction:

Improveaerosol outputVSAvoidheat distribution uniformity

Core Design Contradiction:

ProductivityVSTemperature

Solution Approach 1:

The spacing between material sections is pre-calculated and designed during manufacturing to anticipate heat distribution patterns. This preliminary spacing arrangement ensures that heating elements can effectively reach all sections without creating cold spots, while still maximizing overall material density within the article.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of only varying the spacing distance between sections, the invention optimizes the spatial arrangement in multiple dimensions - including the longitudinal positioning, radial distribution, and angular orientation of sections relative to heating elements - to achieve uniform heat distribution while maintaining high material density.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Temperature

If sections are spaced apart to improve heating uniformity and eliminate cold spots, then temperature distribution is improved, but article length and device complexity increase

Engineering Contradiction:

Improveheat distribution uniformityVSAvoidarticle length

Core Design Contradiction:

TemperatureVSLength of stationary object

Solution Approach 1:

The invention systematically varies the spacing parameters between sections - using different distances, angular positions, and radial offsets - to achieve optimal heat distribution. By carefully adjusting these geometric parameters, uniform heating is achieved without requiring excessive article length, as each spacing value is optimized for its specific function.

Inventive Principle:

Principle #35Parameter changes
