Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating systems face challenges in achieving sufficient mixing of volatile delivery enhancing compounds and nicotine, leading to instability and degradation during storage and use, which affects the efficiency of aerosol formation.
Innovation Solution
An aerosol-generating system comprising an aerosol-generating device with an elongate piercing member that pierces compartments containing a tubular porous element with a delivery enhancing compound and a volatile liquid, controlling airflow to enhance mixing and stability, using a design with a piercing portion, shaft portion, and obstructing portion to define an airflow pathway that ensures effective vaporization and reaction of the compounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the aerosol-generating system uses a simple compartment design without airflow control structures, then the device complexity is reduced, but the mixing of volatile delivery enhancing compound and nicotine is insufficient
Solution Approach 1:
The piercing member acts as an intermediary element between the two compartments. It includes an obstructing portion that extends into the second compartment to control airflow patterns, facilitating mixing of the volatile delivery enhancing compound and nicotine without requiring complex mixing mechanisms. The piercing member mediates the interaction between compartments while maintaining a relatively simple overall design.
Solution Approach 2:
The piercing member introduces localized airflow control within the second compartment. The obstructing portion creates specific flow patterns in the local region where it extends, enhancing mixing at the critical interface between compartments without requiring complex structures throughout the entire device.
2Stability of the object's composition
If the aerosol-generating system stores volatile delivery enhancing compound and nicotine in separate sealed compartments, then the stability and retention of compounds during storage is improved, but the mixing of reactants during use needs additional mechanisms
Solution Approach 1:
The system divides the aerosol-generating article into two separate sealed compartments: a first compartment containing the volatile delivery enhancing compound sorbed on a tubular porous element, and a second compartment containing nicotine. This segmentation maintains stability during storage by keeping compounds separated and sealed, while allowing simple mixing during use through the piercing member mechanism.
Solution Approach 2:
The piercing member serves as an intermediary that connects the two sealed compartments during use. It allows controlled airflow and mixing of the separated compounds without requiring complex mixing mechanisms, maintaining both storage stability and operational simplicity.
3Ease of operation
If the aerosol-generating system uses a piercing member without an obstructing portion, then the ease of operation is improved, but the airflow control and mixing efficiency are reduced
Solution Approach 1:
The piercing member with its obstructing portion automatically controls airflow patterns when inserted. The obstructing portion self-regulates the mixing process by creating appropriate flow resistance and patterns, eliminating the need for additional complex control mechanisms while maintaining high aerosol generation efficiency.
