Plenum Chamber Airflow Path in Aerosol Provision System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision systems, such as electronic cigarettes, face challenges in efficiently directing and guiding airflow through their components, particularly upstream of the vaporizer, leading to convoluted and inefficient airflow paths.
Innovation Solution
The introduction of a plenum chamber and optimized air inlet designs within the aerosol provision system, which allows airflow to pass from outside the system, through an air inlet, into the plenum chamber, and then into the cartridge, improving airflow direction and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional airflow paths are used in aerosol provision systems, then the system structure is simpler, but the airflow efficiency deteriorates and paths become convoluted
Solution Approach 1:
A plenum chamber is introduced as an intermediary component between the air inlet and the cartridge. This plenum chamber receives air from the air inlet and distributes it to the cartridge, creating a more efficient airflow path. The plenum chamber acts as a mediator that optimizes airflow distribution without requiring complex integrated designs, thus improving airflow efficiency while maintaining reasonable structural complexity.
2Productivity
If airflow paths are optimized to be less convoluted, then airflow efficiency improves, but detection capability may worsen
Solution Approach 1:
The plenum chamber serves as an intermediary that maintains detection capability while optimizing airflow. By positioning sensors within the plenum chamber, the system can detect user activation through airflow patterns even as the overall path becomes more direct and efficient. The plenum chamber provides a strategic location for sensor placement that preserves detection functionality.
Solution Approach 2:
The system incorporates sensors that detect airflow through the plenum chamber and provide feedback to control system activation. This feedback mechanism ensures that user detection remains effective even with optimized airflow paths, as the sensors monitor airflow patterns and trigger appropriate responses based on detected user intent.

AI summary
A body for an aerosol provision system for generating an aerosol from an aerosolizable material includes a receptacle for releasably receiving a cartridge. The receptacle includes at least one air inlet and a plenum chamber. In this way, the receptacle is configured for allowing the cartridge to engage against a portion of the plenum chamber when the receptacle is releasably receiving the cartridge, for then allowing a flow of air to pass from outside of the receptacle, through the at least one air inlet, into the receptacle, and then into the plenum chamber.
