Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Aerosol generating devices are vulnerable to unauthorized use by minors due to their operation based on simple user input, lacking effective security measures.

Innovation Solution

Incorporation of an inhalation sensor to detect user inhalation patterns and a controller to compare these patterns with pre-stored data for user authentication, ensuring only authorized users can operate the device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If simple button input operation is used, then ease of operation is improved, but device security deteriorates allowing unauthorized use by minors

Engineering Contradiction:

Improveoperation simplicityVSAvoiddevice security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the simple mechanical button press system with a biometric authentication system using an inhalation sensor. The sensor detects inhalation patterns (flow rate, volume, waveform) to verify user identity, substituting mechanical input with physiological-based authentication while maintaining ease of use through natural breathing actions.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If inhalation sensor and authentication system are added, then device security is improved, but device complexity increases

Engineering Contradiction:

Improvedevice securityVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The inhalation sensor serves multiple functions: it detects user identity through inhalation pattern recognition, monitors usage behavior, and triggers authentication protocols. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while achieving enhanced security.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses the user's own physiological characteristics (inhalation patterns) as the authentication key, eliminating the need for external authentication devices or complex credential systems. The user's breathing serves both as the authentication mechanism and the identification data source.

Inventive Principle:

Principle #25Self-service

3Reliability

If inhalation data analysis is implemented, then unauthorized use prevention is improved, but loss of time increases due to authentication process

Engineering Contradiction:

Improveunauthorized use preventionVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system pre-stores legitimate user inhalation patterns and authentication criteria in memory. During actual use, the system only needs to compare real-time inhalation data against these pre-established patterns, significantly reducing authentication time compared to complex verification processes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system performs authentication based on key inhalation parameters (flow rate, volume, waveform characteristics) rather than analyzing every possible variable. This selective measurement approach achieves sufficient authentication accuracy while minimizing processing time and computational requirements.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

An aerosol generating device includes an inhalation sensor configured to detect user's inhalation, and a controller configured to compare first inhalation data obtained from the inhalation sensor with second inhalation data stored beforehand to perform user authentication according to a comparison result. Therefore, unauthorized use by an unauthorized user or a minor may be prevented.
