Solution Overview
Problem
Existing aerosol generating devices, such as electronic cigarettes, often fail to produce aerosol that tastes as good as traditional cigarettes due to inefficient heating methods.
Innovation Solution
An aerosol generating device with a shell, mouthpiece assembly, atomizing assembly, circuit board assembly, and connecting assembly, featuring a cylindrical heating body with both inner and outer surfaces that heat a tobacco block, and a thermal baffle to enhance air flow and flavor mixing, powered by a detachable battery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a heating component is used to heat tobacco liquid in an atomizer, then aerosol is generated, but the taste quality of the aerosol is poor compared to ordinary cigarettes
Solution Approach 1:
The patent changes the heating parameters by using a heating body that directly contacts the tobacco block, heating it to a temperature range of 200-400°C. This temperature control parameter change enables efficient aerosol generation while preserving the tobacco's original taste, resolving the contradiction between taste quality and heating efficiency.
Solution Approach 2:
The patent replaces the conventional atomizer's liquid heating mechanism with a solid tobacco block heating system. The heating body directly contacts and heats the tobacco block, substituting the mechanical atomization process with a simpler thermal heating process that better preserves taste while improving heating efficiency.
2Productivity
If a heating body with both inner and outer surfaces is used to heat a tobacco block, then heating efficiency and taste are improved, but device complexity increases
Solution Approach 1:
The heating body is segmented into distinct inner and outer surfaces, with the inner surface contacting the tobacco block and the outer surface exposed to air flow. This segmentation allows independent optimization of each surface's function, improving heating efficiency while keeping the overall structure manageable.
Solution Approach 2:
The heating body merges the heating function with the structural support function. The same component that provides structural support for the tobacco block also serves as the heating element, eliminating the need for separate heating components and reducing overall device complexity despite the dual-surface heating capability.
3Reliability
If air flow is enhanced through the use of a thermal baffle, then flavor mixing is improved, but device complexity increases
Solution Approach 1:
The thermal baffle acts as an intermediary component between the heating body and the air flow path. It mediates the interaction by directing air flow across the heating surface, enabling effective flavor mixing without requiring complex active flow control mechanisms. The baffle passively shapes the air flow to achieve the desired mixing effect.
