Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing aerosol-generating systems face challenges with Bluetooth Low Energy (BLE) pairing incompatibilities with various external computing devices, leading to difficulties in unlocking and youth access prevention, which are time-consuming and costly to resolve.

Innovation Solution

The system employs connectionless communications to transmit and receive unlock requests and grants, using a pre-shared secret and one-time random values to generate a unique unlock code, enabling seamless unlocking without BLE pairing, and ensuring youth access prevention through secure data validation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If Bluetooth Low Energy (BLE) pairing is used to unlock the aerosol-generating system, then youth access prevention can be implemented, but compatibility issues with external computing devices occur and firmware updates are required

Engineering Contradiction:

Improveyouth access preventionVSAvoidcompatibility with external computing devices

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces an intermediary unlocking mechanism that does not rely on BLE pairing between the aerosol-generating device and external computing devices. Instead, the system uses an intermediate unlocking code or token that can be obtained through alternative methods (such as web-based authentication, QR code scanning, or parental controls), thereby mediating the security requirement without the compatibility issues of direct BLE pairing.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical BLE pairing system with an alternative unlocking mechanism. The original BLE-based authentication system is substituted with a more versatile unlocking approach that may involve web services, cloud-based authentication, or other communication protocols that do not suffer from the same compatibility limitations as BLE pairing.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If BLE pairing incompatibilities are resolved through firmware updates, then compatibility improves, but the process is time-consuming and expensive

Engineering Contradiction:

ImprovecompatibilityVSAvoidtime to resolve incompatibilities

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by designing the unlocking system from the outset to support multiple authentication methods and communication protocols. Rather than starting with BLE pairing and later adding compatibility fixes through firmware updates, the system is pre-configured with versatile unlocking capabilities that work across different device types and operating systems from day one.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent applies universality by creating an unlocking mechanism that serves multiple functions and works with various external computing devices without requiring device-specific firmware updates. The system can authenticate through multiple channels (web, mobile app, QR code, parental controls) making it universally compatible across different platforms and devices.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If dedicated unlock apps are required for BLE pairing, then youth access prevention is enforced, but the system becomes more complex and harder to use

Engineering Contradiction:

Improveyouth access preventionVSAvoidunlocking process

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent uses an intermediary unlocking approach where the authentication process is mediated through alternative channels rather than requiring a dedicated unlock app. The intermediary mechanism could be a web-based authentication system, a parental control portal, or other third-party services that verify age and authorization without requiring users to install and navigate complex dedicated applications.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent enables self-service unlocking where users can authenticate and unlock the device through intuitive, built-in mechanisms such as scanning QR codes, entering verification codes, or using simplified web forms. This eliminates the need for complex dedicated unlock apps while maintaining youth access prevention through automated verification processes.

Inventive Principle:

Principle #25Self-service

AI summary

An aerosol-generating system is provided, in a locked state in which the aerosol-generating system is prevented from generating aerosol, the aerosol-generating system being configured to: receive an unlock grant from an external computing device using connectionless communications, and after receiving the unlock grant, transition the aerosol-generating system from the locked state to an unlocked state in which the aerosol-generating system is allowed to generate aerosol.
