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.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air insulating spaces or insulating material are used between the heater and outer housing, then thermal insulation is improved, but device volume and weight increase
Solution Approach 1:
The solid-state energy storage device is integrated into the air insulating space between the heater and outer housing, combining the functions of thermal insulation and energy storage into a single component arrangement, thereby eliminating the need for separate insulating materials and reducing overall device volume
Solution Approach 2:
The solid-state energy storage device serves dual purposes: it provides electrical energy storage for the heating element and simultaneously acts as a thermal insulator by occupying the air insulating space, preventing heat transfer to the outer housing without requiring additional insulating materials
