Solution Overview

Problem

Current vaping device technologies fail to consistently and conveniently verify the age and identity of users, allowing underage individuals to access and use vaping devices, and limit flavor options for adult users, leading to imperfect solutions.

Innovation Solution

A personal vaping device (PVD) that authenticates users through a combination of thumbprint recognition and bioimpedance analysis, ensuring only authorized users can activate the heating chamber by matching a unique identity data combination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If repeated reauthentication is required, then age verification reliability is improved, but user convenience deteriorates

Engineering Contradiction:
Improveage verification reliabilityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary action by establishing a unique identifier for each authorized user during initial setup, storing this identifier in the device memory. This preliminary identification allows the system to automatically recognize authorized users without requiring repeated manual authentication, thus improving convenience while maintaining security through the pre-established unique identifiers.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If simple identification methods are used, then ease of operation is improved, but security against underage access deteriorates

Engineering Contradiction:
Improveease of accessVSAvoidunderage access prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system introduces an intermediary mechanism by generating a unique identifier that combines multiple authentication factors (such as fingerprint, facial recognition, or other biometric data) during the initial setup. This unique identifier acts as a mediator between the user and the vaping device, providing both ease of access for authorized users and strong security against underage access through the complexity of the identifier generation process.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If multiple authentication factors are required, then security is improved, but device complexity increases

Engineering Contradiction:
Improveuser authorization securityVSAvoidauthentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system applies merging by combining multiple authentication factors (biometric data, device usage patterns, temporal information) into a single unique identifier during the initial setup. This consolidation reduces the complexity of the authentication system during normal operation, as the device only needs to verify the pre-generated unique identifier rather than evaluating multiple separate authentication factors in real-time, while still maintaining high security standards.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A personal vaping device (“PVD”) for age authenticated vaping is configured to read the thumbprint of an active user of the vaping device and, essentially simultaneously, perform a bioimpedance analysis (“BIA”) to measure a bioimpedance signature of the active user. The combination of the user's thumbprint with the bioimpedance signature defines a unique identity data combination for the user that can be compared to stored identity data combinations of authorized users. If the identity data combination of the active user matches, within a statistical confidence level, a stored identity data combination of an authorized user, the vaping device “unlocks” its heating chamber such that power is supplied to the coil/heating element for vaporizing e-juice.
