Separable Helical Coil for Aerosol Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision devices for generating aerosols from aerosol-generating materials often rely on combustion, which can be harmful and inefficient, and lack effective mechanisms for accessing and heating the material without burning it.
Innovation Solution
The aerosol provision device incorporates a heating assembly with a helical coil that generates a varying magnetic field to heat the aerosol-generating material without combustion, and a separable coil design that allows access to the heating zone for easy insertion and maintenance of the material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed coil design is used to generate magnetic field for heating, then the heating function is stable, but access to the heating zone is difficult
Solution Approach 1:
The coil is divided into two separate portions (first coil portion and second coil portion) that can be moved relative to each other. This segmentation allows the coil to be opened to provide access to the heating zone while maintaining the complete coil structure for stable heating function when closed and connected.
2Ease of operation
If the coil is made separable to allow access to heating zone, then ease of operation improves, but electrical connection complexity increases
Solution Approach 1:
The electrical connection between the first and second coil portions is designed to be dynamic rather than fixed. The portions can be electrically connected when closed and disconnected when opened, allowing the system to adapt its connection state based on operational requirements without permanent complex wiring.
3Ease of repair
If a separable coil design is implemented, then maintenance access improves, but manufacturing complexity increases
Solution Approach 1:
The coil is manufactured as separate portions that can be independently produced and then assembled. This segmentation simplifies manufacturing by allowing each portion to be made separately with standard connections, rather than requiring complex integrated coil assembly processes.
