Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating devices face inefficiencies in battery usage, leading to potential battery exhaustion during use, and there is a need to miniaturize the holder to improve portability.
Innovation Solution
A cradle and holder system where the cradle has a higher battery capacity than the holder, with processors that manage power supply based on charge levels and temperature, ensuring efficient battery use and allowing the holder to be miniaturized by reducing its battery size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the holder battery capacity is increased to ensure sufficient power supply during use, then the reliability of aerosol generation is improved, but the holder size increases and portability deteriorates
Solution Approach 1:
The power supply system is segmented into two parts: a small holder battery for portability and a larger cradle battery for sufficient power supply. The holder and cradle work together as a distributed power system, allowing the holder to remain compact while the cradle provides additional energy capacity when the holder is docked.
Solution Approach 2:
The cradle acts as an intermediary power source between the electrical outlet and the holder battery. It charges the holder battery when docked and can directly supply power to the heater, mediating the power transfer to ensure the holder has sufficient energy capacity without carrying a large battery.
2Volume of moving object
If the holder battery size is reduced to miniaturize the holder, then the portability is improved, but the battery may be exhausted during use
Solution Approach 1:
The cradle processor performs preliminary charging of the holder battery when the holder is docked in the cradle. This preliminary action ensures the holder battery is fully charged before use, extending the effective duration of action without increasing the battery size in the portable holder.
Solution Approach 2:
The system maintains continuous power availability through the cradle-holder connection. When the holder is docked, the cradle continuously charges the holder battery or directly supplies power to the heater, ensuring uninterrupted useful action without requiring a large battery in the holder.
3Productivity
If the cradle processor manages power supply based on charge levels, then the battery usage efficiency is improved, but the device complexity increases
Solution Approach 1:
The cradle processor implements feedback control by monitoring the holder battery charge level and adjusting power supply accordingly. When the charge level is sufficient, the processor manages power optimally; when insufficient, it prioritizes charging. This feedback mechanism improves battery usage efficiency without requiring complex control logic.
