Aerosol Generating Device with Auto-Adjusting Cartridge Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating devices lack the ability to efficiently adjust the position of a second cartridge based on the remaining amount of a first cartridge, leading to inconvenient use and potential disruptions in aerosol quality.
Innovation Solution
An aerosol generating device that includes a first cartridge for accommodating a first material, a second cartridge with multiple chambers for accommodating a second material, a remaining amount sensor to detect the first material's remaining amount, and a controller to determine the consumption rate and adjust the position of the second cartridge relative to the first cartridge based on a pre-set reference consumption amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the position of the second cartridge is manually adjusted based on first cartridge consumption, then device complexity is reduced, but ease of operation deteriorates due to required user intervention
Solution Approach 1:
The system automatically monitors the remaining amount of first material in the first cartridge and autonomously adjusts the position of the second cartridge without requiring user intervention. The controller executes the position adjustment based on detected consumption levels, making the system self-servicing.
Solution Approach 2:
The remaining amount sensor continuously detects the consumption level of the first material and feeds this information back to the controller. The controller then uses this feedback to determine when position adjustment is necessary and executes the adjustment accordingly, creating a closed-loop control system.
2Ease of operation
If automatic position adjustment is implemented, then ease of operation is improved, but device complexity increases due to additional sensors and controllers
Solution Approach 1:
The controller serves multiple functions: it controls the atomization process, monitors sensor data, determines consumption levels, and executes position adjustment commands. By making the controller multi-functional, the patent avoids adding separate dedicated components for each function, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent combines the position adjustment mechanism with the existing cartridge assembly structure. The second cartridge is designed to be movable relative to the first cartridge along the aerosol delivery path, integrating the adjustment function into the existing structural framework rather than adding completely separate adjustment mechanisms.
3Productivity
If the second cartridge position is not adjusted, then device complexity remains low, but productivity deteriorates due to inefficient material usage
Solution Approach 1:
The system proactively adjusts the position of the second cartridge before the first cartridge is completely depleted. By monitoring the remaining amount and predicting when adjustment is needed, the system performs the position change in advance, ensuring continuous efficient operation without interruption.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated control system that uses sensor detection and electronic control to determine and execute position changes. This substitution of mechanical user intervention with an automated system improves productivity while managing complexity through integrated control.
4Adaptability or versatility
If multiple chambers are used in the second cartridge, then adaptability is improved for various flavors, but device complexity increases
Solution Approach 1:
The second cartridge is divided into multiple independent chambers, each containing different second materials for various flavors or functions. This segmentation allows the system to offer diverse aerosol characteristics while keeping each chamber relatively simple in structure, managing overall complexity through modular design.
Solution Approach 2:
The system dynamically adjusts which chamber is positioned at the aerosol delivery path based on the consumption level of the first material. The controller can change the relative position of the second cartridge to bring different chambers into alignment with the delivery hole, providing adaptability without requiring multiple separate cartridges.

AI summary
An aerosol generating device includes a first cartridge including a first material and a delivery hole, a second cartridge including chambers for accommodating a second material through which an aerosol passes, a position of the second cartridge with respect to the first cartridge being changeable, a remaining amount sensor configured to detect a remaining amount of the first material, and a controller configured to determine a consumption amount at which the first material is consumed with respect to a usage chamber that currently passes the aerosol based on the detected remaining amount of the first material and to compare the consumption amount of the first material with a pre-set reference consumption amount of the first material with respect to the usage chamber, thereby determining a position changing time at which changing of a position of the second cartridge is required.
