Aerosol Device Safety: Preventing Overheating and Electrical Risks
Here’s PatSnap Eureka !
Summary
Problems
Aerosol generating devices face risks of overheating, overcurrent, short circuits, overcharging, and over-discharging, leading to dangerous situations in various use environments.
Innovation solutions
Incorporating a temperature sensor and controller within the device to monitor internal component temperatures and prevent abnormal operations by stopping the device when overheating or other hazardous conditions are detected.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If a heater is used to generate aerosol by heating to high temperature, then aerosol generation efficiency is improved, but the risk of overheating and dangerous situations increases
Why choose this principle:
The patent applies preliminary action by installing temperature sensors and control circuits before overheating incidents occur. The system proactively monitors temperature levels and implements preventive cooling or shutdown mechanisms when threshold values are approached, thereby preventing dangerous situations before they manifest while maintaining efficient aerosol generation during normal operation.
Principle concept:
If a heater is used to generate aerosol by heating to high temperature, then aerosol generation efficiency is improved, but the risk of overheating and dangerous situations increases
Why choose this principle:
The patent implements feedback control through temperature sensors that continuously monitor the heater's temperature and feed this information back to a control unit. Based on this feedback, the system automatically adjusts power supply to the heater or activates cooling mechanisms, creating a closed-loop control system that maintains safe operating temperatures while preserving aerosol generation efficiency.

Abstract
An aerosol generating device according to one embodiment may include: a housing that forms an exterior of the aerosol generating device and includes an opening into which a cigarette is inserted; a heater that generates an aerosol by heating the cigarette; a battery that supplies power to the heater; a temperature sensor that senses a temperature of an internal component of the aerosol generating device; and a controller that prevents abnormal operation of the aerosol generating device based on the temperature of the internal component sensed by the temperature sensor.
