Crescent-Opening Mouthpiece with Absorbent Insert for Droplet Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional smoking articles often suffer from accumulated droplets in the flowtube, leading to an unpleasant user experience due to e-liquid buildup and subsequent large droplets entering the user's mouth.
Innovation Solution
The aerosol consumable device features a mouthpiece with crescent-shaped openings and a liquid absorbing insert, which directs aerosol through the openings and absorbs accumulated droplets, enhancing user experience by preventing large droplet formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional flowtube is used in aerosol delivery devices, then the device structure is simple, but accumulated droplets form in the flowtube leading to unpleasant user experience
Solution Approach 1:
The mouthpiece is divided into multiple functional zones: a hydrophobic zone for droplet separation, a hydrophilic zone for droplet absorption, and aerosol passageways. This segmentation allows different regions to perform specialized functions that collectively prevent accumulated droplets while maintaining overall device functionality
Solution Approach 2:
The liquid absorbing insert acts as an intermediary component between the aerosol generation chamber and the user's mouth. It intercepts and absorbs accumulated droplets before they can reach the user, while allowing aerosol to pass through via its internal channel
2Productivity
If e-liquid is delivered through a standard aerosol system, then aerosol generation is efficient, but large droplets form and enter the user's mouth causing unpleasant experience
Solution Approach 1:
Different regions of the mouthpiece are赋予 different surface properties: the outer surface of the liquid absorbing insert is hydrophobic to repel and separate droplets, while the internal channel surface is hydrophilic to absorb accumulated droplets. This local differentiation allows the system to maintain aerosol flow efficiency while eliminating harmful droplet formation
Solution Approach 2:
The liquid absorbing insert utilizes porous absorbent material within its structure to capture and retain accumulated droplets. The porous nature provides large surface area for absorption while maintaining permeability for aerosol passage through the internal channel

AI summary
The present disclosure provides an aerosol consumable device. In some cases, the aerosol consumable device includes at a first end, a mouthpiece portion having a top surface comprising two or more crescent-shaped openings arranged on opposite sides of an aerosol cap having a closed end. The aerosol consumable device further comprises a liquid absorbing insert positioned within the mouthpiece portion between the first end and a second end opposite the first end, and an aerosol tube positioned between the liquid absorbing insert and the second end. The liquid absorbing insert defines an internal aerosol channel. Upon a draw on the mouthpiece portion by a user, a first portion of aerosol generated by the aerosol consumable device travels through the internal aerosol channel and through the crescent-shaped openings and the aerosol tube is configured to direct accumulated droplets on an inner surface of the aerosol tube into the liquid absorbing insert.
