Solution Overview

Problem

Aerosol-generating devices face challenges in providing users with clear progress and power availability feedback during usage sessions, leading to inefficient energy consumption and potential depletion of aerosol-forming substrates.

Innovation Solution

Incorporating a motion detection unit and controller to detect user gestures, allowing the device to output visual, haptic, or audio indications of session progress and available sessions, thereby enhancing user feedback and energy management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If continuous visual indication is provided during usage session, then user awareness of progress is improved, but device complexity and energy consumption increase

Engineering Contradiction:

Improveuser awareness of progressVSAvoidindicator system complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The indicator system provides progress information periodically through gesture-triggered queries rather than continuously. The motion detection unit detects specific gestures (e.g., shaking the device) that initiate status queries, transforming the continuous information provision into periodic updates. This reduces energy consumption and system complexity while maintaining user awareness at relevant moments.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The device enables users to self-initiate status queries through simple gestures. Instead of the system continuously monitoring and displaying progress, the user actively requests information when needed by performing a gesture, making the information retrieval self-service oriented and reducing continuous system overhead.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If gesture-based status query is implemented, then user feedback is enhanced, but device complexity increases due to additional sensors and processing

Engineering Contradiction:

Improveuser feedback mechanismVSAvoidmotion detection system

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The motion detection unit acts as an intermediary between the user and the indicator system. Instead of direct button presses or complex interfaces, the gesture recognition system mediates user intent by detecting movements and translating them into status query commands. This provides an intuitive feedback mechanism while managing complexity through a dedicated intermediary component.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Traditional mechanical buttons or switches are replaced with gesture-based motion detection. The system substitutes physical mechanical interaction with motion sensing and pattern recognition, enabling more intuitive user feedback while leveraging modern sensor technology to manage the complexity trade-off.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If multiple gestures are recognized for different queries, then user control is improved, but difficulty of detecting and measuring increases

Engineering Contradiction:

Improvequery type selectionVSAvoidgesture recognition accuracy

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

Different gesture types are segmented into distinct, easily distinguishable patterns. Instead of recognizing subtle variations in a continuous gesture space, the system defines discrete gesture categories (e.g., shake for progress, tap for sessions remaining) that are simple to detect and differentiate, reducing recognition difficulty while maintaining versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of trying to detect complex continuous gestures and interpret their meaning, the system inverts the approach by defining simple, intentional gestures where each motion pattern directly corresponds to a specific query type. This simplifies the detection and measurement task while achieving adaptable user control.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

An aerosol-generating device for generating an aerosol from an aerosol-forming substrate is provided, the aerosol-generating device being configured to generate the aerosol during a usage session, the aerosol-generating device including: an indicator system; a motion detector configured to detect movement of the aerosol-generating device and identify a first gesture associated with the detected movement; and a controller, in which, in response to the first gesture being identified by the motion detector, the controller is configured to control the indicator system to output a user detectable indication indicative of the number of usage sessions available.
