Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vaporizer heating methods lead to dry-burning when the material to be heated is insufficient, resulting in a shortened service life of the vaporizer.
Innovation Solution
A method and apparatus for heating a vaporizer that involves real-time monitoring of the thermal properties of the heating element, determining thermal equilibrium based on predefined rules, and controlling the output power to prevent dry-burning by stopping heating when the output power falls below a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional heating method is used without real-time monitoring, then the heating process is simple, but the vaporizer temperature rises sharply when material is insufficient, causing dry-burning and short service life
Solution Approach 1:
The patent implements real-time feedback control by continuously monitoring the thermal property (resistance or temperature) of the heating element and comparing it with stable values obtained during trigger operations. When the monitored value exceeds the stable value by more than a threshold, the system adjusts or stops heating to prevent dry-burning, thereby extending vaporizer service life without requiring complex additional hardware
Solution Approach 2:
The system performs self-diagnosis and self-protection by automatically detecting its own thermal state through real-time monitoring of the heating element's thermal property. The control unit uses this self-monitoring data to determine whether to continue heating, eliminating the need for external monitoring devices and keeping the system relatively simple while preventing damage
2Reliability
If real-time thermal monitoring is implemented, then dry-burning is prevented and service life is extended, but the system complexity increases
Solution Approach 1:
The control unit performs multiple functions: it controls heating power, monitors thermal properties, compares values with thresholds, determines thermal equilibrium states, and decides when to stop heating. By making the control unit multi-functional, the patent avoids adding separate dedicated monitoring and control devices, thereby preventing excessive system complexity while achieving reliable dry-burning prevention
Solution Approach 2:
The system monitors changes in thermal parameters (resistance or temperature) of the heating element to detect material depletion. By focusing on parameter changes rather than absolute values and using simple threshold comparisons, the system achieves effective monitoring with minimal computational complexity, extending service life without proportionally increasing system complexity

AI summary
A heating method and device for an atomizer, a computer apparatus, and a storage medium. The heating method comprises: upon detecting a trigger operation, acquiring, in real time, a sample value of a thermal property of a heating element in an atomizer (102); determining, according to a currently acquired sample value, whether the atomizer has attained thermal equilibrium (104); if it is determined that the atomizer has attained thermal equilibrium, taking a sample value of the thermal property of the heating element at which thermal equilibrium has been attained as a stable value, controlling differences between sample values of the heating element and the stable value to be within a first range, and acquiring, in real time, a first output power of the atomizer (106); and if the first output power is less than a first power threshold, stopping heating the heating element (108). The heating method and device for an atomizer, the computer apparatus, and the storage medium can extend service life of an atomizer.
