Aerosol Charge Indicator for Dual-Battery Power Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-combustible aerosol provision devices face challenges in efficiently managing battery power distribution and charge indication, particularly in devices with increased functionalities that demand more from the base unit battery, leading to complexities in determining and indicating the charge levels of both the device and base batteries.
Innovation Solution
An aerosol provision system comprising a heater assembly, a device battery, a base unit with a base battery, and a controller that determines charge levels and directs power distribution, using an indicator assembly to display charge status through illuminating elements, prioritizing device battery recharging when both are connected to a power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the base unit battery capacity is increased to support increased functionalities, then the device can operate longer and support more features, but the device size and weight increase
Solution Approach 1:
The battery system is segmented into two separate batteries: a base unit battery housed in the charging base and a device battery integrated into the aerosol provision device. This segmentation allows the device to maintain lightweight construction while the base unit provides extended capacity for multiple charging cycles, resolving the contradiction between operation duration and device weight.
2Loss of information
If the system monitors and indicates charge levels of both batteries, then user awareness of battery status is improved, but the control system complexity increases
Solution Approach 1:
The control system implements feedback mechanisms that automatically monitor charge levels of both the base unit battery and device battery, and provide real-time visual feedback through indicator assemblies. The system uses simple indicator lights to communicate charge status without requiring complex user interaction or interpretation, reducing information loss while maintaining manageable system complexity.
Solution Approach 2:
The control system operates autonomously to monitor and indicate battery charge levels without requiring user intervention. The indicators automatically display the charge status of both batteries, and the system self-manages the charging process, reducing the complexity burden on the user while providing comprehensive charge information.
3Loss of information
If the indicator assembly displays device battery charge level, then users can monitor device battery status, but it may cause confusion when base battery charge is also relevant
Solution Approach 1:
The indicator assembly provides differentiated visual information for different battery types. When the device is docked and charging, the indicators specifically display base unit battery charge level. When the device is removed from the dock, the indicators display device battery charge level. This contextual differentiation ensures users receive relevant information without confusion, as the displayed charge level always corresponds to the appropriate battery for the current operational state.
