Aerosol Heater Power Feedback for Smoking Time Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating devices often end heating operations prematurely, either by the number of puffs or time, leading to insufficient smoking time for users, as they either stop before the aerosol generating material is exhausted or continue beyond the desired duration.
Innovation Solution
An aerosol generating device with a controller that calculates the power consumption over a preset time period and adjusts the heating based on a reference power amount, ensuring the heating operation continues until the material is adequately vaporized, providing a more satisfying smoking experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If heating operation is controlled based on preset time or number of puffs, then device operation is simple, but smoking time is insufficient and material is not fully utilized
Solution Approach 1:
The controller monitors the actual power consumption of the heater in real-time and compares it with the expected power consumption. Based on this feedback, the controller dynamically adjusts the heating operation to ensure adequate vaporization of the aerosol generating material, thereby extending smoking time without significantly increasing device complexity.
Solution Approach 2:
The patent changes the control parameter from fixed time/puff count to dynamic power consumption monitoring. By measuring actual power usage and comparing it with expected values, the system adapts the heating duration to match the actual material consumption rate, extending smoking time while maintaining reasonable control complexity.
2Loss of substance
If heating operation continues until preset time elapses, then material utilization is complete, but user satisfaction decreases due to excessive duration
Solution Approach 1:
The system continuously monitors power consumption and compares actual values with expected values. When the aerosol generating material is fully vaporized, the power consumption pattern changes, providing feedback to the controller to terminate heating, thus achieving complete material utilization without excessive duration.
Solution Approach 2:
The heater and controller system automatically detects when the aerosol generating material is exhausted through power consumption monitoring and self-terminates the heating operation, eliminating the need for user intervention and preventing excessive heating duration.
3Use of energy by moving object
If heating operation stops at preset time, then energy consumption is controlled, but aerosol generating material is wasted
Solution Approach 1:
The controller monitors actual power consumption and compares it with expected power consumption patterns. This feedback mechanism allows the system to extend heating operation when material remains and adjust energy consumption accordingly, preventing material waste while maintaining energy efficiency.
Solution Approach 2:
The heating operation transitions from static preset time control to dynamic power consumption-based control. The system continuously adapts heating duration based on real-time power monitoring, optimizing the balance between energy consumption and material utilization.

AI summary
Disclosed is an aerosol generating device including a heater that heats an aerosol generating material and a controller that controls power to be supplied to the heater. The controller calculates a first power amount indicating a power amount used by the heater during a preset first time period after a heating operation of the heater is started, and controls the heating operation of the heater based on whether the first power amount is greater than or equal to a preset reference power amount.
