Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no preheating method is provided when the electronic cigarette is turned on, then the device structure remains simple and operation is straightforward, but the viscosity of cigarette liquid increases at low temperature, reducing fluidity and preventing proper vapor production
Solution Approach 1:
The patent applies preliminary action by implementing a preheating routine that activates automatically when the electronic cigarette is turned on. The microcontroller executes a preheating program that heats the cigarette liquid before normal vaporization begins, ensuring the liquid reaches appropriate temperature and fluidity. This preliminary heating action prevents the technical contradiction by preparing the liquid in advance to overcome low-temperature viscosity issues.
2Reliability
If preheating is implemented to warm up the cigarette liquid, then vapor production is improved in cold conditions, but the heating device complexity and power consumption increase
Solution Approach 1:
The patent applies dynamics by making the preheating process adjustable and adaptive. The microcontroller allows modification of preheating parameters such as temperature, time, and power levels. The system can dynamically adjust heating intensity and duration based on detected temperature conditions and user preferences, optimizing energy consumption while ensuring adequate liquid fluidity for reliable vapor production.
Solution Approach 2:
The patent applies parameter changes by allowing the microcontroller to modify preheating parameters (temperature, time, power) based on operating conditions. The system can change heating parameters dynamically during the preheating process and across different operating scenarios, enabling efficient energy utilization while achieving the required liquid fluidity for reliable vaporization.
3Adaptability or versatility
If preheating parameters are fixed in the microcontroller, then the system is simple to operate, but the device lacks adaptability to different user preferences and environmental conditions
Solution Approach 1:
The patent applies self-service by enabling users to independently adjust preheating parameters through an interface connected to the microcontroller. Users can modify temperature, time, and power settings according to their preferences and environmental conditions without requiring technical assistance or complex procedures. The system serves itself by providing intuitive parameter adjustment capabilities that adapt to individual user needs while maintaining ease of operation.

AI summary
An electronic cigarette preheating method and preheating system are provided. The preheating method performs data interaction by communication connection established between an intelligent terminal and the electronic cigarette, allows for displaying and changing preheating parameters on a control software interface of the intelligent terminal, and sends the updated preheating parameters to the microcontroller MCU arranged in the electronic cigarette to replace previous preheating parameters preset in the microcontroller MCU. When the electronic cigarette is turned on, based on real-time temperature value detected by temperature sensor arranged in the electronic cigarette, determining whether preheating of the cigarette liquid stored inside the liquid storage chamber is required by means of the microcontroller MCU. If yes, based on preheating parameters and preset routine, controlling the heating device of the electronic cigarette by means of the microcontroller MCU to perform heating for the preset heating time or until the preset target temperature value is reached. Then, ending the preheating and entering the available stand-by state of the electronic cigarette. After preheating, the cigarette liquid or liquid substances containing drugs may easily penetrate or flow to the heating device for vaporization, such that the electronic cigarette may easily produce vapor even at low temperature.
