Segmented Mouthpiece Assembly for Aerosol Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hybrid aerosol provision devices require frequent replacement of the material container, which is often smaller than the liquid cartridge, leading to the desire to detach the container while keeping the liquid cartridge attached.
Innovation Solution
A mouthpiece assembly for an aerosol provision device, comprising a first housing for the user's mouth and a second housing for containing a material through which the aerosol flows, with the two housings connected to form a releasable assembly that can be attached to a section of the aerosol provision device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the container for material is releasably attached to the cartridge, then the material can be replaced frequently, but the structure becomes more complex and the aerosol flow path becomes longer
Solution Approach 1:
The mouthpiece assembly is segmented into two separate housings: a first housing that forms the mouthpiece and is releasably attachable to the cartridge, and a second housing that contains the material. This segmentation allows the material container to be independently replaced while keeping the cartridge attached, resolving the contradiction between frequent material replacement and structural complexity.
2Adaptability or versatility
If the container for material is releasably attached to the cartridge, then the material can be replaced frequently, but the aerosol flow path becomes longer
Solution Approach 1:
By segmenting the mouthpiece assembly into a first housing (mouthpiece) and a second housing (material container) that are connected but can be independently attached/detached, the design allows frequent material replacement without significantly extending the aerosol flow path through the entire device structure.
3Ease of operation
If the mouthpiece assembly is configured to be releasably connected to the aerosol provision device, then user convenience and hygiene are improved, but the connection mechanism becomes more complex
Solution Approach 1:
The mouthpiece assembly is designed as a separable unit with a releasable connection to the aerosol provision device. This segmentation improves hygiene by allowing the mouthpiece to be replaced frequently and enhances user convenience, while the connection mechanism complexity is managed through modular design.
Solution Approach 2:
The first housing (mouthpiece) and second housing (material container) are merged into a single mouthpiece assembly that connects to the aerosol provision device as one unit, simplifying the connection mechanism while maintaining the ability to replace the entire assembly for hygiene purposes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows for easy replacement of the material container without detaching the liquid cartridge, improving user convenience and hygiene by ensuring the mouthpiece is replaced with the same frequency as the material, and enhancing the aerosol flow quality.
Implementation Method 1
a first barrier that is porous to the flow of aerosol and which prevents material in the second housing from exiting the second housing

AI summary
A mouthpiece assembly for an aerosol provision device includes a first housing for being received, in use, in a mouth of a user, and a second housing for containing a material through which, in use, an aerosol generated by the aerosol provision device flows before passing out of the mouthpiece assembly for inhalation by the user. The first housing and the second housing are connected together to form the mouthpiece assembly, and the mouthpiece assembly is configured to be releasably connectable to a section of the aerosol provision device.
