Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing heat-not-burn devices require lengthy preheating times and continuous heating between inhalations, leading to poor user experience and high power consumption.
Innovation Solution
A control method for a heat-not-burn device that includes a heating component located at the periphery of the aerosol generating substrate, which rotates along the central axis of the substrate after each inhalation to heat a different region, allowing for rapid temperature increase and reduced power consumption by detecting inhalation actions in real time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If continuous heating is performed to maintain high temperature for timely response to next inhalation, then the device can respond quickly to user inhalation, but power consumption increases significantly
Solution Approach 1:
The heating component performs preliminary heating of the aerosol generating substrate before inhalation occurs. This preheating prepares the substrate in advance, ensuring that when the user inhales, the aerosol can be generated immediately without delay, thus achieving fast response while avoiding continuous heating and reducing power consumption.
Solution Approach 2:
Instead of continuous heating, the device uses periodic heating cycles - heating before inhalation, stopping during intervals, and reheating when next inhalation is detected. This periodic action maintains the ability to respond quickly to inhalation while significantly reducing overall power consumption compared to continuous heating.
2Temperature
If preheating is performed for more than 5 seconds before use, then the aerosol generating substrate reaches optimal temperature for aerosol generation, but user waiting time increases and user experience deteriorates
Solution Approach 1:
The device performs preliminary heating of the aerosol generating substrate as soon as it is inserted, even before the user is ready to inhale. This background preheating occurs silently and prepares the substrate in advance, so when the user actually inhales, the temperature is already optimal and no waiting time is required, thus improving user experience while ensuring proper heating.
Solution Approach 2:
The heating component operates continuously at a lower power level in the background to maintain the substrate at optimal temperature throughout the device usage period. This continuous but efficient heating eliminates the need for separate preheating phases and ensures the substrate is always ready for immediate aerosol generation upon inhalation.
3Reliability
If heating is maintained throughout the entire inhalation process and intervals between inhalations, then consistent aerosol quality is maintained, but energy waste increases due to unnecessary heating during intervals
Solution Approach 1:
The device uses sensors to detect user inhalation in real-time and provides feedback control to the heating component. When inhalation is detected, heating is activated or intensified; when inhalation stops, heating is reduced or stopped. This feedback mechanism ensures aerosol generation consistency during actual use while eliminating energy waste during intervals when no inhalation occurs.
Solution Approach 2:
The heating system activates automatically based on detected inhalation patterns without requiring continuous external control. The system serves itself by detecting when heating is needed (during inhalation) and when it can be stopped (during intervals), thereby maintaining aerosol generation reliability while minimizing energy waste through intelligent, demand-based operation.

AI summary
A heat-not-burn device control method for a heat-not-burn device that includes a heating component configured to heat an aerosol generating substrate includes: detecting, in real time after startup, whether an inhalation action occurs; controlling, when detecting that the inhalation action occurs, the heating component to start heating and remain at a preset target temperature so as to enable the heating component to heat a corresponding region of the aerosol generating substrate, the heating component being located at a periphery of the aerosol generating substrate and deviating from a central axis of the aerosol generating substrate; and controlling, when detecting that the inhalation action stops, the heating component and/or the aerosol generating substrate to rotate along the central axis of the aerosol generating substrate so as to enable the heating component and the aerosol generating substrate to generate a corresponding displacement in a circumferential direction of the aerosol generating substrate.
