Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Aerosol generating devices are vulnerable to unauthorized use by minors due to their operation based on simple button inputs, lacking effective user authentication mechanisms.

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, such as adults, 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 due to unauthorized use by minors

Engineering Contradiction:

Improveoperation simplicityVSAvoiddevice security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

An inhalation sensor is introduced as an intermediary between the user and the device operation. The sensor detects inhalation patterns and transmits this data to a controller that compares it with pre-stored authentication data, thereby mediating the access control process without requiring complex user interactions

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The mechanical button press system is supplemented with a biological detection system (inhalation sensor). Instead of relying solely on mechanical input, the system substitutes part of the operation mechanism with physiological signal detection, comparing inhalation patterns to authenticate users

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If user authentication through inhalation detection is implemented, 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 presence, authenticates user identity through pattern comparison, and can potentially monitor usage patterns. This multi-functionality reduces the need for separate authentication components, thereby limiting the increase in device complexity

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system performs self-authentication by automatically comparing real-time inhalation data with pre-stored authentication data without requiring external verification systems. The controller autonomously makes authentication decisions, eliminating the need for complex external authentication infrastructure

Inventive Principle:

Principle #25Self-service

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.
