Inhalation Device Heating Control for Rapid Post-Cleaning Drying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inhalation devices require users to wait for the accommodating portion to dry after cleaning with cleaning agents, leading to inconvenience and potential delivery of poor-quality smoking flavor aerosol.
Innovation Solution
An inhalation device with a control unit that operates the heating unit based on different heating information when the substrate is accommodated or not, allowing for efficient drying and improved convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the accommodating portion is cleaned using cleaning agents such as alcohol or water, then the cleanliness of the accommodating portion is improved, but the interior of the accommodating portion becomes wet and requires waiting time to dry naturally
Solution Approach 1:
The heating unit performs drying action immediately after cleaning before the user needs to use the device again. By anticipating the drying need and executing it proactively through automated heating, the system eliminates the waiting time that would otherwise be required for natural evaporation.
Solution Approach 2:
The heating unit automatically dries the accommodating portion without requiring user intervention or waiting. The control unit detects when cleaning has occurred and autonomously activates the heating unit to evaporate moisture, making the drying process self-service rather than passive natural drying.
2Ease of operation
If the user uses the inhalation device while the interior of the accommodating portion is wet, then immediate use is possible, but poor-quality smoking flavor aerosol is delivered to the user
Solution Approach 1:
The system performs drying action before the user uses the device again. The control unit detects when the substrate is removed (indicating cleaning) and automatically activates the heating unit to dry the accommodating portion, ensuring the space is dry before the next use and preventing quality degradation.
Solution Approach 2:
The heating unit, which generates heat for vaporizing the aerosol source, is repurposed to evaporate moisture from the accommodating portion. This converts the heat function into a drying function that eliminates the harmful effect of moisture without requiring additional components.
3Speed
If the heating unit operates continuously to dry the accommodating portion, then the drying speed is improved, but energy consumption increases
Solution Approach 1:
The heating unit operates intermittently rather than continuously. The control unit activates the heating unit for specific drying periods after cleaning detection, then stops heating when drying is sufficient, creating a periodic operation pattern that balances drying speed with energy conservation.
Solution Approach 2:
The control unit adjusts the heating parameters (temperature and duration) based on the drying need. By optimizing the heating intensity and duration to the minimum required for effective drying, the system achieves sufficient drying speed while minimizing energy consumption.

AI summary
An MCU (1) of an inhalation device (100) operates a heating unit (121C) based on a stick heating profile for heating a stick-type substrate (150) when the stick-type substrate (150) is accommodated in an accommodating portion (140C), and operates the heating unit (121C) based on a cleaning heating profile different from the stick heating profile when the stick-type substrate (150) is not accommodated in the accommodating portion (140C).
