Aerosol Heater Pause Temperature Control to Limit Ingredient Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices face issues with active ingredients vaporizing during pauses due to high heater temperatures, leading to inefficiency and potential waste when the device is paused before the aerosol generating material is fully consumed.
Innovation Solution
The device includes a controller that lowers the heater temperature during pauses and resumes heating when the pause is released, with customizable temperature profiles and notifications for user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the heater temperature is maintained high during pause, then the heating speed is fast and aerosol generation is efficient, but the active ingredient vaporizes and is consumed unnecessarily
Solution Approach 1:
The heater temperature is made dynamic rather than static. During pause operation, the temperature is automatically reduced from the high operating temperature to a lower temperature, and then restored to the original high temperature when the pause is ended. This dynamic temperature adjustment resolves the contradiction by maintaining high temperature for efficiency during operation while reducing temperature to prevent unnecessary vaporization during pause.
Solution Approach 2:
The temperature parameter of the heater is changed based on the operational state. When pause is detected, the temperature parameter is modified from the high operating level to a lower level, and then restored when pause ends. This parameter change allows the system to maintain productivity during operation while preventing active ingredient loss during pause.
2Loss of substance
If the heater temperature is lowered during pause, then the active ingredient is protected from vaporization, but the reheating time after pause increases
Solution Approach 1:
Instead of completely stopping heating during pause, the system applies partial heating action by maintaining a lower temperature rather than fully reducing to zero. This partial action preserves the active ingredient from unnecessary vaporization while minimizing the reheating time needed after pause, as the heater only needs to restore temperature from the lower pause level rather than from zero.
3Duration of action of moving object
If the operation time is extended during pause, then the total smoking time is increased, but the heating control complexity increases
Solution Approach 1:
The system uses feedback from the pause detection to automatically adjust the operation time. When pause is detected, the controller extends the operation time by the pause duration, and when pause ends, the heating is restored. This feedback mechanism automatically handles the time extension without requiring complex manual control, as the system self-adjusts based on the pause event.

AI summary
An aerosol generating device controls supplying of power to a heater such that a temperature of the heater reaches a temperature lower than a temperature defined in a temperature profile when receiving a user input signal to pause an operation of the aerosol generating device, controls the supplying of power to the heater such that, when the pause is released, the temperature of the heater reaches the temperature defined in the temperature profile, and extends an operation time by a paused time.
