Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating systems face limitations in efficiency and design constraints due to the types of magnetic field generating devices and the parameters affecting inductive coupling, such as separation distance and relative sizes of magnetic field generators and susceptors, which hinder the development of improved aerosol generating systems for non-combustible aerosol provision devices.
Innovation Solution
The proposed system incorporates inductor coils and ferritic susceptors, where the susceptors are formed by mixing iron (III) oxide with additional metallic elements like barium, manganese, nickel, or zinc, and are arranged to be heated by a varying magnetic field, with aluminum elements positioned in close proximity to enhance heating and aerosol generation, allowing for efficient aerosol production without combustion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If traditional inductor coils are used with conventional susceptors, then the device structure is simple, but the inductive coupling efficiency is limited due to separation distance and relative size constraints
Solution Approach 1:
The patent applies composite materials by using ferritic susceptor materials that combine magnetic properties with enhanced heating efficiency. The ferritic material composition allows for improved magnetic coupling between the inductor coil and susceptor, resolving the contradiction by using advanced materials rather than simply increasing device complexity
Solution Approach 2:
The patent changes physical parameters by optimizing the separation distance between the inductor coil and susceptor, as well as adjusting the relative sizes and orientations of these components. These parameter optimizations improve inductive coupling efficiency without requiring fundamentally more complex device architecture
2Loss of energy
If the separation between magnetic field generating device and susceptor is reduced to improve coupling, then inductive coupling efficiency improves, but device design flexibility is constrained
Solution Approach 1:
The patent applies dynamics by making the heating assembly removable and replaceable, allowing the system to adapt to different articles and usage scenarios. This dynamic design enables optimization of coupling parameters for each specific application while maintaining overall system versatility through modular architecture
3Productivity
If conventional heating methods are used, then the device structure is simple, but aerosol generation efficiency is insufficient for non-combustible aerosol provision
Solution Approach 1:
The patent replaces conventional mechanical heating systems with an induction heating system that uses electromagnetic fields to heat the ferritic susceptor and indirectly heat the article. This substitution significantly improves aerosol generation efficiency by enabling rapid, controlled heating without combustion, while the modular design keeps the overall system complexity manageable
