Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation devices face challenges in power management, particularly in efficiently charging batteries and reducing the need for high-power external sources for fast pulse charging, which increases costs and device size.
Innovation Solution
A power system comprising a supercapacitor module and a battery module, controlled by a controller that implements a pulse-charging regime by cyclically switching power flows between charging and not charging, allowing the supercapacitor to boost current from a lower power external source and recharge during off periods, thereby reducing energy losses and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a high power external power source is used for fast pulse charging, then charging speed is improved, but device cost and size increase
Solution Approach 1:
The patent introduces a supercapacitor module as an intermediary component between the external power source and the battery module. The supercapacitor receives power from the external source during off-periods and delivers high current to the battery during on-periods, enabling fast pulse charging without requiring a high-power external power source. This mediator allows the system to achieve high charging speeds while using a smaller, lower-power external adapter.
2Productivity
If a high power external power source is used for fast pulse charging, then charging speed is improved, but energy losses increase
Solution Approach 1:
The patent implements a pulse charging regime with periodic on-periods and off-periods. During off-periods, the supercapacitor is charged from the external power source at lower power. During on-periods, the supercapacitor delivers high current to the battery. This periodic action allows the system to achieve fast charging效果 while reducing overall energy losses compared to continuous high-power charging.
3Adaptability or versatility
If pulse charging is implemented without supercapacitor boosting, then device complexity is reduced, but flexibility in power source selection is limited
Solution Approach 1:
The supercapacitor module serves multiple functions: it acts as a power booster during on-periods, as an energy storage device during off-periods, and as a buffer to protect the battery from high current stress. This multi-functionality enables the system to work with various low-power external power sources (USB ports, power banks, wall adapters) while maintaining fast pulse charging capability, thus improving adaptability without proportionally increasing complexity.
