Aerosol Generation Device With Adaptive Capacity Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation devices determine the remaining capacity of secondary batteries using a fixed threshold, which does not account for battery deterioration, leading to premature discard of aerosol sources even when they could still be fully used.
Innovation Solution
The device adjusts the threshold for determining the remaining capacity based on the cumulative number of heating cycles, increasing it as the device is used, to ensure that aerosol sources are not discarded prematurely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed threshold is used to determine remaining battery capacity, then the determination is simple and reliable, but aerosol sources are discarded prematurely even when they could still be fully used
Solution Approach 1:
The patent applies the dynamics principle by making the threshold variable rather than fixed. The threshold is dynamically adjusted based on the cumulative number of heating cycles, allowing the system to adapt to battery deterioration over time. This resolves the contradiction by enabling accurate remaining capacity determination (improving reliability) while preventing premature discarding of aerosol sources (reducing waste).
Solution Approach 2:
The patent changes the parameter of the threshold from a constant value to a variable that depends on the cumulative number of heating cycles. By modifying this parameter based on battery usage history, the system can accurately assess remaining capacity despite battery deterioration, thereby avoiding both false positives (discarding usable sources) and false negatives (allowing insufficient capacity).
2Loss of substance
If the threshold is increased to allow more aerosol sources to be used, then waste is reduced, but the risk of insufficient capacity increases
Solution Approach 1:
The patent implements feedback by using the cumulative number of heating cycles as input to adjust the threshold. This feedback mechanism allows the system to learn from past usage patterns and battery performance, dynamically setting the threshold to maximize aerosol source utilization while maintaining sufficient capacity. The feedback loop prevents both waste (by allowing more sources) and insufficiency (by adjusting based on actual battery state).
3Device complexity
If a fixed threshold is used, then the device complexity is low, but the number of usable aerosol sources is limited
Solution Approach 1:
By transitioning from a static to a dynamic threshold based on heating cycle count, the patent increases productivity (number of usable aerosol sources) with only minimal added complexity (counter and conditional logic). The dynamic adjustment enables the system to fully utilize more aerosol sources per battery charge while maintaining relatively simple device architecture.
