Charging Unit Battery Checks for Uninterrupted Aerosol Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision systems face challenges in ensuring seamless operation during sessions, particularly when the device is disconnected from the charging unit mid-session, due to insufficient battery capacity checks.
Innovation Solution
Implementing controllers in the aerosol provision device and charging unit to determine and ensure sufficient battery capacity before commencing a session, allowing for seamless operation by utilizing both device and charging unit batteries if needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the aerosol provision device relies solely on its own battery capacity, then the device structure remains simple, but the session duration is insufficient when disconnected from the charging unit
Solution Approach 1:
The patent merges the charging unit's battery with the aerosol provision device's battery system, creating a combined power supply architecture. The charging unit's controller and the device's controller communicate to coordinate battery usage, allowing the device to draw power from either battery depending on availability, thereby extending session duration without significantly increasing device complexity
Solution Approach 2:
The charging unit's battery is designed to serve dual purposes: it functions as both a charging source for the device's battery and as a supplemental power source during aerosol provision sessions. This multi-functionality allows the same battery to extend session duration while maintaining simple system architecture
2Reliability
If the system checks battery capacity of both device and charging unit, then seamless operation is ensured, but the control complexity increases
Solution Approach 1:
The controllers perform preliminary battery capacity checks before initiating aerosol provision sessions and before allowing disconnection from the charging unit. By checking battery levels in advance and predicting whether sufficient power remains for the remainder of the session, the system ensures seamless operation without requiring complex real-time monitoring during active use
Solution Approach 2:
The system implements feedback mechanisms where the device's controller communicates battery status and session progress to the charging unit's controller. This feedback loop enables coordinated battery management, allowing the charging unit to provide supplemental power when needed while maintaining simple individual controller designs through distributed intelligence
