Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing aerosol generating devices, such as e-cigarettes, often provide frequent battery-level notifications that can be annoying to users, and there is a need for intelligent battery-level notifications based on usage patterns.

Innovation Solution

The device records periods of active use, detects user puffs, determines if a battery-level notification has been provided, and generates an indication if the battery level is below a predetermined threshold, using configurable rules for session-based or time-based notifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If frequent battery-level notifications are provided to users, then the user is kept informed about battery status, but the user experience deteriorates due to annoyance from excessive alerts

Engineering Contradiction:

Improvebattery status informationVSAvoiduser experience

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent implements periodic battery-level notifications based on usage sessions rather than continuous or frequent alerts. The system determines when to notify the user by checking if a notification was already provided in the current session, creating a periodic notification pattern that balances information provision with user comfort.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system performs preliminary checks before generating notifications by determining whether a battery-level notification has already been provided in the current session. This preliminary action prevents redundant notifications and ensures that information is provided at appropriate intervals without excessive alerts.

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If battery-level notifications are provided at all times, then complete information is given to the user, but the device complexity increases due to continuous monitoring and notification management

Engineering Contradiction:

Improvebattery status informationVSAvoidnotification management system

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the notification system into session-based units, where each usage session is independently tracked. The controller divides the monitoring period into sessions and manages notifications within each session context, reducing overall system complexity compared to continuous monitoring.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The notification system dynamically adapts to usage patterns by tracking sessions and adjusting when notifications are provided. The system transitions between different notification states based on session boundaries and previous notification status, creating a dynamic rather than static notification management approach.

Inventive Principle:

Principle #15Dynamics

AI summary

The invention discloses a method of operating an aerosol generating device comprising recording a period of active use of the device; detecting a puff inhaled by a user; determining if a battery-level notification had been provided to the user in the said period before the puff detection; determining a battery-level of the device if no notification had been provided previously; and generating an indication on the device for the user if the determined battery-level is below a predetermined level.
