Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision systems face challenges in efficiently generating aerosols from replaceable media without combustion, particularly in devices using resistive heating systems, which often require frequent replacement of the medium and lack efficient methods for producing diverse aerosols.
Innovation Solution
A method of forming an aerosol generator involving a resistive heating layer with an electrically conductive material, a layer of aerosol generating material on one side, and heating elements on the other side, which can be formed through cutting, etching, or printing, and optionally incorporating a mesh structure for the aerosol generating material, allowing for efficient and diverse aerosol production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resistive heating systems are used to create aerosol from replaceable medium, then aerosol generation is achieved, but frequent medium replacement is required and diversity of aerosols is limited
Solution Approach 1:
The heating system is segmented into multiple independent heating elements (first heating element, second heating element, etc.) that can independently heat different portions of the aerosol-generating material layer, enabling diverse aerosol generation from a single replaceable unit and reducing replacement frequency
Solution Approach 2:
The heating elements are arranged in multiple dimensions within the heating layer, with each element capable of heating different regions of the aerosol-generating material. This spatial arrangement enables a single replaceable unit to produce multiple types of aerosols by activating different heating elements, thereby reducing the need for frequent medium replacement
2Device complexity
If single-layer heating structure is used, then device simplicity is maintained, but aerosol diversity and efficiency are limited
Solution Approach 1:
The heating layer is segmented into multiple heating elements with different configurations (first heating element with first configuration, second heating element with second configuration), allowing a single-layer structure to achieve aerosol diversity through internal differentiation rather than multiple layers
Solution Approach 2:
Different portions of the heating layer are assigned different local qualities through the use of heating elements with different configurations and positions. Each heating element can be optimized for specific heating requirements, enabling diverse aerosol generation from a unified single-layer structure
