Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Aerosol-generating articles face issues with loose fitting in devices, airflow clogging, and inefficient substrate consumption due to changing diameters and excessive wrapping paper usage, leading to frequent cleaning needs.

Innovation Solution

The aerosol-generating article features a downstream section with protruding wrapping paper sections that extend upstream, ensuring secure positioning, maintaining airflow, and reducing wrapping paper requirements by creating a reliable connection between sections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the wrapping paper is extended upstream to provide a reliable connection between sections, then the connection reliability is improved, but the amount of wrapping paper required increases

Engineering Contradiction:

Improveconnection reliabilityVSAvoidwrapping paper consumption

Core Design Contradiction:

ReliabilityVSLoss of substance

Solution Approach 1:

The wrapping paper is segmented into a body portion and separate protruding sections. The protruding sections extend upstream to provide connection reliability, while the body portion maintains a limited circumference coverage. This segmentation allows the wrapping paper to fulfill multiple functions with reduced overall material consumption.

Inventive Principle:

Principle #1Segmentation

2Productivity

If the article diameter changes during consumption, then the substrate consumption is improved, but the article stability in the device deteriorates

Engineering Contradiction:

Improvesubstrate consumptionVSAvoidarticle stability

Core Design Contradiction:

ProductivityVSStability of the object's composition

Solution Approach 1:

The wrapping paper structure is divided into a body portion that maintains a first diameter and protruding sections that extend upstream. This segmentation allows the article to consume substrate effectively while the protruding sections maintain stability by engaging with the device cavity.

Inventive Principle:

Principle #1Segmentation

3Reliability

If the protruding sections are added to the wrapping paper, then the airflow path is maintained, but the device complexity increases

Engineering Contradiction:

Improveairflow pathVSAvoidwrapping paper structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The protruding sections of the wrapping paper serve multiple functions simultaneously: they maintain airflow paths, provide structural stability, and enable reliable connection between article sections. This multi-functionality reduces the need for separate components, thereby not increasing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
