Solution Overview
Problem
Existing aerosol generation devices for tobacco heating products lack effective control over airflow and ventilation, leading to inconsistent aerosol temperature and flavor profiles during use.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If airflow control mechanisms are added to regulate ventilation, then aerosol temperature and flavor consistency is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic airflow control by making the air inlet opening adjustable in size during the use session. The controller dynamically modifies the opening size based on session progress, transitioning from a larger opening at the start to a smaller opening as the session continues. This dynamic adjustment maintains stable aerosol temperature and flavor throughout the session, resolving the contradiction between stability and complexity.
Solution Approach 2:
The patent changes the physical parameter of the air inlet opening size to control airflow. By varying the opening size parameter throughout the use session, the system regulates the amount of air mixing with the heated aerosol, thereby maintaining consistent temperature and flavor characteristics despite the added control mechanism.
2Object-affected harmful factors
If airflow through the first opening is increased at the beginning of a use session, then initial heat discomfort is mitigated, but aerosol temperature consistency deteriorates
Solution Approach 1:
The system dynamically adjusts the air inlet opening size based on the progress of the use session. At the beginning of the session, the opening is larger to allow more airflow, which mitigates initial heat discomfort. As the session progresses, the opening size is reduced to maintain aerosol temperature consistency. This time-varying parameter adjustment resolves the contradiction between reducing harmful effects and maintaining stability.
Solution Approach 2:
The system performs preliminary airflow adjustment at the start of the use session by maintaining a larger opening size before the aerosol generation process fully stabilizes. This preliminary action prevents initial heat discomfort, and then the system transitions to a different operational state to maintain temperature consistency during the main usage phase.
