Innovation Solution
An electronic vaporization device with a heating control method that adjusts the heating temperature of a heating body based on inhalation parameters, progressively increasing the target temperature threshold in stepwise manner to optimize nicotine and substance release, using a ΔT=(U*I*t-Q dissipation)/(M*C) relation to adjust heating parameters such as voltage, current, and time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the heating body heats the flavor cartridge at a constant temperature, then the device structure is simple, but the nicotine release amount is low and attenuates seriously
Solution Approach 1:
The patent implements dynamic heating temperature adjustment based on inhalation parameters. The control module progressively increases the target temperature threshold in a stepwise manner according to inhalation duration or inhalation times, making the heating temperature adaptive rather than static. This resolves the contradiction by enabling variable temperature control that optimizes nicotine release without requiring overly complex external equipment.
Solution Approach 2:
The patent changes the heating temperature parameter dynamically based on inhalation characteristics. By adjusting the target temperature threshold according to inhalation duration or cumulative inhalation times, the system optimizes nicotine release at different stages of usage. This parameter adaptation resolves the contradiction between maintaining simple device structure and achieving sufficient nicotine release.
2Quantity of substance
If the heating temperature is increased to improve nicotine release, then the nicotine release amount increases, but the taste deteriorates due to excessive temperature
Solution Approach 1:
The patent implements dynamic temperature adjustment that adapts to inhalation progression. The target temperature threshold is progressively increased in steps based on inhalation parameters, allowing the system to optimize nicotine release at each stage without exceeding optimal temperature ranges. This dynamic adaptation prevents taste deterioration while maintaining effective nicotine release.
Solution Approach 2:
The patent employs periodic or staged heating temperature adjustment based on inhalation cycles. By dividing the heating process into stages corresponding to different inhalation parameters, the system applies appropriate temperature levels at each stage, preventing excessive temperature exposure that would degrade taste while ensuring sufficient nicotine release over the complete inhalation sequence.
3Stability of the object's composition
If the heating temperature is adjusted frequently to optimize release, then the substance release uniformity improves, but the control system complexity increases
Solution Approach 1:
The patent implements dynamic but structured temperature adjustment based on inhalation parameters. The control module progressively increases the target temperature threshold in a stepwise manner, providing structured control that ensures uniform substance release without requiring excessively frequent or complex adjustments. This balanced approach achieves release uniformity while maintaining reasonable control system complexity.

AI summary
The present invention relates to an electronic vaporization device, and a heating control apparatus and a heating control method thereof. The heating control method includes: obtaining a current inhalation parameter according to an inhalation situation of a user; obtaining a corresponding target temperature threshold according to the current inhalation parameter, where the target temperature threshold is progressively increased in a stepwise manner as the inhalation parameter increases; and detecting a current heating temperature value of a heating body, and adjusting the current heating temperature value of the heating body to the target temperature threshold. In the present invention, secondary heating is performed on a flavor cartridge/cigarette through the heating body. In addition, when the heating body heats the same flavor cartridge/cigarette, as an inhalation action is performed, a heating temperature of the heating body is gradually progressively increased in a stepwise manner, so that nicotine and other effectively substances in the flavor cartridge/cigarette are uniformly released in different inhalation stages, thereby improving the taste.
