Aerosol Article Extracting Structure for Stable Airflow Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol generating devices face issues with inconsistent airflow paths and residue introduction due to gaps between the extracting portion and the housing, leading to unstable aerosol flavor and potential device damage.
Innovation Solution
The device features an extracting portion that moves in response to the cover portion's movement, ensuring close contact with the housing to maintain a stable airflow path and prevent residue ingress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the extracting portion is fixed relative to the housing, then the structure is simple, but gaps form between the extracting portion and housing causing unstable airflow and residue introduction
Solution Approach 1:
The extracting portion is designed to move dynamically relative to the housing, transitioning between retracted and extended positions. This dynamic configuration allows the extracting portion to maintain close contact with the housing during aerosol generation, eliminating gaps that would cause airflow instability and residue introduction, while remaining simple when not in use.
Solution Approach 2:
The extracting portion is separated into a movable component that can be independently controlled. This segmentation allows the extracting portion to be displaced specifically when needed for aerosol generation, while the housing and other components remain stationary, reducing overall structural complexity while improving reliability.
2Reliability
If the extracting portion is displaced when cover opens, then gap is prevented and airflow is stable, but the mechanism complexity increases
Solution Approach 1:
The movement mechanism of the extracting portion is merged with the cover opening/closing mechanism. When the cover opens, the extracting portion is automatically displaced through this integrated mechanism, ensuring consistent airflow and aerosol generation without requiring a separate, complex control system.
Solution Approach 2:
The extracting portion's movement is automatically triggered by the cover opening action itself. The mechanism uses the cover's motion to drive the extracting portion's displacement, eliminating the need for additional actuators or control systems, thereby maintaining simplicity while ensuring reliable aerosol consistency.
3Ease of operation
If gap exists between extracting portion and housing, then extraction is easy, but residues are introduced and device function decreases
Solution Approach 1:
The extracting portion dynamically adjusts its position based on operational needs. During extraction, it maintains easy access for article insertion, but during aerosol generation, it moves to close the gap with the housing, preventing residue introduction while preserving ease of operation.

AI summary
An aerosol generating device includes an accommodating portion accommodating an aerosol generating article through an opening formed in an upper housing, a cover portion configured to open and close the opening, and an extracting portion mounted in the accommodating portion, contacting with the aerosol generating article, and configured to extract the aerosol generating article by moving from a first position to a second position in an longitudinal direction of the accommodating portion when the cover portion opens the opening.
