Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the power of the e-cigarette is increased to improve vapor production, then the heating efficiency is improved, but the temperature of the heating element becomes excessively high causing scorching of the liquid guiding member and generation of harmful substances
Solution Approach 1:
The patent implements a temperature feedback control system where a temperature detection unit continuously monitors the heating element temperature and feeds this information to a control unit. The control unit adjusts the operating voltage accordingly to maintain temperature within a safe range, preventing scorching while allowing high power operation. This resolves the contradiction by enabling high power output without exceeding safe temperature thresholds.
Solution Approach 2:
The patent dynamically changes the operating voltage parameter based on temperature conditions. The operating voltage adjusting unit converts original voltage into adjusted operating voltage selectively supplied to the heating element according to heating temperature. This parameter adjustment allows the system to operate at high power when cool and reduce power when temperature rises, resolving the contradiction between power output and temperature control.
2Productivity
If the heating element operates at high temperature to improve atomization efficiency, then the vapor production is enhanced, but the service life of the heating element is shortened due to easy breaking
Solution Approach 1:
The temperature feedback control system continuously monitors heating element temperature and adjusts operating voltage to prevent excessive heating. This ensures the heating element operates within safe temperature ranges that maintain both atomization efficiency and structural integrity, thereby extending service life while preserving productivity.
Solution Approach 2:
The control system proactively adjusts operating voltage before the heating element reaches dangerous temperature levels. By preemptively reducing power when temperature approaches critical thresholds, the system prevents thermal stress that would cause breaking, thus protecting the heating element and extending its service life while maintaining acceptable atomization performance.
3Productivity
If the heating element temperature is increased to improve e-liquid vaporization, then the aerosol generation is enhanced, but the e-liquid may burst and injure the user's oral cavity
Solution Approach 1:
The temperature detection unit and control unit work together to maintain heating element temperature within a safe operating range. This feedback control ensures sufficient heat for effective aerosol generation while preventing temperature excursions that would cause e-liquid bursting and potential user injury, thus resolving the contradiction between productivity and safety.
Solution Approach 2:
The control system takes preliminary action by adjusting operating voltage to prevent the heating element from reaching temperatures that would cause e-liquid bursting. By proactively controlling temperature before dangerous conditions develop, the system maintains effective aerosol generation while preventing harmful effects to the user.

AI summary
The present invention relates to an temperature control system of an e-cigarette, which includes a power supply, a liquid guiding member, and a heating element, and further includes an operating voltage input unit separately connected to the power supply and the heating element, a temperature detection unit including a voltage detection module and a temperature processing module that are connected to each other, and an operating voltage adjusting unit separately connected to the temperature processing module and the heating element. According to the present invention, a temperature of the heating element is controlled by using the temperature control system. This avoids the following problems: When the e-cigarette operates, because the temperature of the heating element increases with a longer operating time, the liquid guiding member is burnt or e-liquid molecules are cracked to produce a burnt taste, thereby affecting human health as well as smoke taste and user experience.
