Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating devices face challenges in optimizing aerosol generation, particularly in terms of droplet size and consistency, which are influenced by factors such as cooling, air pressure, ambient temperature, and humidity, and lack a mechanism to ensure consistent user experience and efficient manufacturing.
Innovation Solution
The introduction of a two-piece Venturi portion, with parts integrated into the main body and mouthpiece, enhances aerosol generation by controlling droplet size and ensuring compatibility with correct mouthpieces, allowing interchangeable mouthpieces for customizable user experiences and reducing manufacturing complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional single-piece Venturi portion is used, then the device structure is simpler, but the aerosol generation consistency and droplet size control are insufficient
Solution Approach 1:
The Venturi portion is divided into two separate pieces: a first Venturi piece integrated with the main body and a second Venturi piece integrated with the mouthpiece. This segmentation allows for precise manufacturing of each piece independently, improving aerosol generation consistency while managing device complexity through modular assembly.
2Manufacturing precision
If the Venturi portion is integrated into a single piece, then manufacturing is easier, but the droplet size distribution control is insufficient
Solution Approach 1:
By separating the Venturi portion into two pieces with distinct functions (first piece in main body, second piece in mouthpiece), each component can be manufactured with optimized tolerances and features for its specific role, achieving better droplet size distribution control while maintaining ease of manufacture through standard modular production processes.
3Adaptability or versatility
If the mouthpiece is fixed to the main body, then the device structure is more stable, but the adaptability and customization options are reduced
Solution Approach 1:
The mouthpiece is made detachable from the main body through a removable connection, allowing the system to dynamically switch between different mouthpiece configurations. This enables customization of delivery profiles while maintaining structural stability during use through secure attachment mechanisms.
4Productivity
If a two-piece Venturi portion is used, then aerosol generation is enhanced, but the device complexity increases
Solution Approach 1:
The two-piece Venturi portion is segmented into functional components distributed across the main body and mouthpiece assemblies. This segmentation enhances aerosol generation by optimizing airflow control in each section while managing overall device complexity through modular design that allows independent manufacturing and assembly of each piece.

AI summary
The invention relates to an aerosol-generating device comprising a main body, a mouthpiece, which is configured removably attachable to the main body and a two-piece Venturi portion. The two-piece Venturi portion comprises an inlet portion, an outlet portion, a main airflow channel extending between the inlet portion and the outlet portion and a constricted airflow channel arranged in the main airflow channel. The inlet portion of the two-piece Venturi portion is at least partly arranged in the main body when the mouthpiece is attached to the main body, and the outlet portion of the two-piece Venturi portion is at least partly arranged in the mouthpiece or integrated with the mouthpiece.
