1Productivity

If the heating element operates at high power continuously, then heating efficiency is improved, but temperature accumulation becomes excessive causing inconsistent aerosol taste

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSTemperature

Solution Approach 1:

The heating element operates in periodic cycles with distinct phases: a first time period with first power parameters, a second time period with second power parameters, and a third time period with third power parameters. This periodic operation allows the heating element to efficiently heat during the first phase while controlling temperature accumulation through reduced power in subsequent phases, thereby maintaining consistent aerosol taste throughout the suction process.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The control module dynamically changes the power parameters supplied to the heating element across different time periods. By adjusting power parameters (voltage, current, or power level) from high in the first time period to lower in the second and third time periods, the system optimizes heating efficiency while preventing excessive temperature accumulation that would cause taste inconsistency.

If the heating element temperature is rapidly increased, then heating efficiency is improved, but heat accumulation may cause inconsistent aerosol quality

Engineering Contradiction:

Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The heating process is divided into periodic stages with different power levels. The first time period enables rapid temperature increase for efficient heating, while the second and third time periods with reduced power parameters ensure temperature stabilization and prevent excessive heat accumulation, thereby maintaining reliable and consistent aerosol quality throughout the operation.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The control module performs preliminary heating at high power in the first time period to rapidly bring the heating element to the required temperature. Subsequently, power parameters are reduced in the second and third time periods to maintain temperature within an optimal range, preventing overheating and ensuring consistent aerosol quality from the outset.

Inventive Principle:
Principle #10Preliminary action
