Movable Top Cover Ejecting Aerosol-Generating Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerosol-generating devices require regular cleaning to remove unwanted residues of aerosol-forming substrates from the heater and cavity, which is inconvenient and time-consuming.
Innovation Solution
An aerosol-generating device with a movable top cover that automatically ejects spent aerosol-generating articles and includes a cleaning mechanism to remove residues during the ejection process, eliminating the need for manual cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the top cover remains stationary and the cavity remains open, then the device structure is simple and easy to operate, but residues accumulate on the heater and cavity walls requiring regular manual cleaning
Solution Approach 1:
The top cover is made movable between an extended position (cavity accessible) and a retracted position (cavity closed), allowing the system to dynamically change its state based on operational needs. This resolves the contradiction by enabling the cavity to be open during use for ease of operation, and closed during storage to prevent contamination.
Solution Approach 2:
The ejector automatically ejects spent aerosol-generating articles from the cavity when the top cover is retracted, and the cleaning element automatically cleans the heater and cavity walls during the same motion. This self-service mechanism eliminates the need for manual cleaning while maintaining simplicity of operation.
2Object-affected harmful factors
If the top cover is made movable with automatic ejection and cleaning mechanisms, then contamination is prevented and cleaning is automated, but the device structure becomes more complex
Solution Approach 1:
Multiple functions are merged into the single motion of the top cover: the retraction of the top cover simultaneously triggers the ejector to eject spent articles and the cleaning element to clean the heater and cavity. This merging reduces device complexity by using one coordinated mechanism instead of separate independent systems for each function.
Solution Approach 2:
The top cover serves multiple functions: it protects the cavity when retracted, triggers automatic ejection of spent articles, and activates the cleaning mechanism. This multi-functionality reduces the need for separate components, thereby managing device complexity while achieving contamination prevention and automated cleaning.
3Ease of operation
If the cavity remains permanently open for article insertion, then the device is easy to use, but unwanted contamination from outside enters the cavity
Solution Approach 1:
The top cover dynamically transitions between extended (open) and retracted (closed) positions. During article insertion, the cover is extended for easy access. After use, the cover is retracted to close the cavity and prevent contamination, resolving the contradiction between ease of use and contamination prevention.
Solution Approach 2:
The top cover is retracted to the closed position before article insertion begins, establishing a clean environment in advance. The cover remains closed during storage and only opens when needed, preventing contamination from entering the cavity in the first place.
