Solution Overview

Problem

Existing non-combustible aerosol provision devices lack visibility and identification features for users, making it difficult to determine the presence and usage status of aerosol-generating materials.

Innovation Solution

An article for non-combustible aerosol provision devices is designed with an aerosol-generating section surrounded by an outer wrapper featuring windows and a visual indicator, allowing users to see the aerosol-generating material and identify usage through visible changes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the aerosol-generating section is completely enclosed by the outer wrapper, then protection and containment are improved, but visibility of the aerosol-generating material deteriorates

Engineering Contradiction:
ImprovecontainmentVSAvoidvisibility
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The outer wrapper is designed with different properties in different regions: opaque material for protection and containment, and transparent windows for visibility. This local differentiation allows the wrapper to simultaneously provide both containment and visibility functions without compromise.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The outer wrapper is segmented into multiple portions with different transparency characteristics. Opaque portions provide containment while transparent window portions provide visibility, allowing the structure to fulfill multiple functions through division of labor among its segments.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If the outer wrapper is made opaque for protection, then safety and containment are improved, but user identification and visibility of usage status deteriorate

Engineering Contradiction:
ImproveprotectionVSAvoidusage status identification
Core Design Contradiction:
Object-affected harmful factorsVSLoss of information

Solution Approach 1:

The visual indicator layer changes color or appearance based on usage status, providing visual feedback to users. This color change mechanism allows users to identify whether the aerosol-generating material has been used without compromising the protective function of the opaque wrapper.

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The visual indicator layer acts as an intermediary between the opaque outer wrapper and the user. It translates the usage status into visible signals that can be perceived through the opaque material or at the ends of the article, bridging the information gap while maintaining protection.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If the outer wrapper is made transparent for visibility, then user identification and visibility are improved, but protection and containment deteriorate

Engineering Contradiction:
ImprovevisibilityVSAvoidprotection
Core Design Contradiction:
Loss of informationVSObject-affected harmful factors

Solution Approach 1:

Instead of making the entire wrapper transparent, the invention uses local quality by applying transparency only where needed (at the ends and through windows) while maintaining opacity in the bulk material for protection. This localized approach provides visibility without compromising overall containment.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The wrapper is segmented into transparent and opaque portions. The transparent segments at the ends and windows provide visibility and identification, while the opaque segments maintain protection and containment, allowing both functions to coexist through structural division.

Inventive Principle:
Principle #1Segmentation

4Loss of information

If windows are added to the outer wrapper for visibility, then user identification is improved, but structural integrity and protection deteriorate

Engineering Contradiction:
ImprovevisibilityVSAvoidstructural integrity
Core Design Contradiction:
Loss of informationVSStrength

Solution Approach 1:

The windows are formed as thin transparent films or layers integrated into the wrapper structure. These thin film windows provide visibility while maintaining the overall structural integrity and protective function of the wrapper, avoiding the need for large openings that would compromise strength.

Inventive Principle:
Principle #30Flexible shells and thin films
