Solution Overview

Problem

Existing aerosol-generating systems face issues with non-authentic consumables being used with authentic devices, leading to potential harm to users, and the lack of customizable heating profiles for different consumables results in sub-optimum aerosol generation.

Innovation Solution

The aerosol-generating device incorporates a sensor to scan longitudinally-spaced indicators on the consumable, which encodes information about the consumable's characteristics. This information is used by a controller to select the appropriate operation mode, ensuring only authentic consumables are heated, and allowing for specific heating profiles based on the consumable type.

Solution Approach 1:

The system performs preliminary identification of the consumable type by scanning indicators before heating begins. Based on this preliminary identification, the controller pre-selects the appropriate heating profile from stored configurations, enabling optimized heating for different consumables without real-time complex calculations.

Inventive Principle:

Solution Approach 2:

The system changes heating parameters (temperature, power level, heating duration) based on the identified consumable type. Different heating profiles are applied to different consumables, allowing optimization of aerosol generation for each specific consumable type while maintaining a relatively simple device architecture.
