Solution Overview

Problem

Existing aerosol generating devices face challenges in minimizing size and weight due to the need for thermal insulation between the heater and the outer housing, which occupies valuable space.

Innovation Solution

The integration of a solid-state energy storage device within the aerosol generating device, positioned between the heater and the outer housing, serves as both additional energy storage capacity and thermal insulation, reducing the need for separate insulating materials.
