Solution Overview

Problem

Users may re-use aerosol generating articles, leading to changes in flavor and discomfort due to reuse, necessitating a solution to prevent reuse.

Innovation Solution

An aerosol generating device with a deformation guiding portion that deforms the aerosol generating article upon initial insertion, allowing detection of reuse through sensors and preventing operation or alerting the user.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users re-insert a used aerosol generating article, then the device allows operation, but the flavor of the aerosol changes and user comfort deteriorates

Engineering Contradiction:

Improvedevice operationVSAvoidaerosol flavor consistency

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The deformation guiding portion performs a preliminary action by deforming one end of the aerosol generating article during initial insertion. This deformation creates a permanent physical change that serves as a marker to distinguish first use from reuse, allowing the device to prevent subsequent operations that would compromise flavor consistency

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The sensor provides feedback by detecting whether one end of the aerosol generating article has been deformed. Based on this feedback, the controller determines whether the article is being inserted for the first time or reused, and accordingly allows or blocks device operation to maintain aerosol flavor consistency

Inventive Principle:

Principle #23Feedback

2Reliability

If a deformation guiding portion is added to detect reuse, then reuse prevention is achieved, but device complexity increases

Engineering Contradiction:

Improvereuse detection accuracyVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The deformation guiding portion acts as an intermediary element between the aerosol generating article and the sensor. It translates the physical state of the article (used or unused) into a detectable deformation signal, enabling reliable reuse detection without requiring complex sensing mechanisms

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The aerosol generating article itself serves the dual function of being both the consumable item and the source of detection information. Its own physical deformation upon insertion provides the signal needed for reuse detection, eliminating the need for separate identification mechanisms or additional components

Inventive Principle:

Principle #25Self-service

AI summary

An aerosol generating device includes: an accommodation portion configured to accommodate an aerosol generating article through an opening; and a deformation guiding portion that comes into contact with one end of the aerosol generating article when the aerosol generating article is inserted into an accommodation portion. The deformation guiding portion deforms the one end of the aerosol generating article when the aerosol generating article is inserted for the first time into the accommodation portion such that the aerosol generating device detects whether an aerosol generating article is being reused based on whether its end is deformed or not.
