Solution Overview
Problem
In heat-not-burn devices, continuous high-temperature heating leads to inefficient energy consumption, inconsistent taste, and loss of aerosol-forming substrate due to prolonged heating during user breaks, affecting user experience.
Innovation Solution
A heating control method that dynamically adjusts the heating element's temperature based on user actions, employing infrared radiation with a heating body and tube element to maintain low temperatures during breaks and high temperatures during vaping, ensuring efficient energy use and consistent taste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the aerosol-forming substrate is continuously heated at high temperature, then aerosol generation is maintained, but energy consumption increases and substrate is lost during user breaks
Solution Approach 1:
The heating element dynamically adjusts its temperature based on user behavior detection. When vaping is detected, temperature increases to a first temperature for optimal aerosol generation. When no vaping is detected for a predetermined time, temperature decreases to a second temperature to conserve energy and prevent substrate loss. This dynamic adjustment resolves the contradiction between maintaining productivity and reducing energy consumption.
Solution Approach 2:
The system changes the temperature parameter of the heating element based on detected user actions. The controller adjusts the heating element's temperature between a first temperature (during vaping) and a second temperature (during breaks), optimizing both aerosol generation efficiency and energy consumption based on actual usage conditions.
2Stability of the object's composition
If continuous high-temperature heating is maintained, then aerosol generation is consistent, but taste becomes inconsistent and charring occurs
Solution Approach 1:
The heating element transitions between different temperature states based on real-time detection of vaping actions. During vaping, it reaches the first temperature for optimal aerosol generation. During breaks, it decreases to the second temperature, preventing charring and burning while maintaining substrate readiness. This dynamic temperature control ensures consistent taste without harmful charring effects.
3Speed
If the heating element is kept at high temperature during breaks, then rapid aerosol generation is ready, but most substrate is lost
Solution Approach 1:
The system changes the temperature parameter dynamically. During vaping, the heating element operates at the first temperature for rapid aerosol generation. During breaks, it decreases to the second temperature, which is sufficient to maintain substrate readiness while preventing excessive heat that would cause substrate loss. This parameter adjustment balances speed and substance preservation.

AI summary
A heating control method for a heat-not-burn device that includes a heating element for heating an aerosol-forming substrate includes: controlling the heating element so as to increase from an initial temperature to a first temperature when heating is started, and maintaining the first temperature; controlling the heating element so as to increase from a current temperature to a second temperature when detecting a puffing action, the second temperature being greater than the first temperature; and controlling the heating element so as to decrease from a current temperature to a third temperature when detecting that the puffing action ends, the third temperature being less than the second temperature.
