Aerosol Heater Timing Control for Pause-Aware Puff Duration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices face issues with user satisfaction due to inadequate control methods that either terminate heating prematurely or result in incomplete aerosol generation, leading to unsatisfactory smoking experiences.
Innovation Solution
An aerosol generating device with a controller that manages heating based on operation time and includes a timer that pauses and restarts, allowing for a customizable smoking experience by considering pause times in addition to preset operation times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If heating is terminated when a preset time has elapsed after heating is started, then the operation time is controlled, but the aerosol generating material is not sufficiently exhausted and the cigarette has to be discarded
Solution Approach 1:
The patent applies dynamics by making the operation time adjustable rather than fixed. The controller allows users to modify the operation time parameter to match their actual usage patterns, transforming a static time limit into a dynamic parameter that adapts to user behavior. This resolves the contradiction by enabling the system to extend heating duration when users take longer puffs or pause between puffs, ensuring complete aerosol generation without premature termination.
2Productivity
If heating is terminated when the number of accumulated puffs reaches a preset number of puffs, then the puff count is controlled, but the smoking time is less than the smoking time desired by the user
Solution Approach 1:
The patent applies parameter changes by allowing users to modify both the number of puffs parameter and the operation time parameter according to their preferences. The controller adjusts heating duration based on the relationship between puff count and individual puff duration, transforming fixed parameters into adjustable ones. This enables the system to extend total smoking time when users take fewer but longer puffs, resolving the contradiction between puff count control and desired smoking duration.

AI summary
An aerosol generating device includes at least one heater configured to heat an aerosol generating material, a memory storing at least one temperature profile and an operation time of the aerosol generating device, a timer turned on by receiving a second control signal and turned off by receiving a first control signal, and a controller configured to control power supplied to the at least one heater based on the operation time, wherein the operation time is stored as a first time, and the controller is further configured to operate the aerosol generating device by adding a second time, in which the timer operates in a turned-on state, to the first time.
