Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional aerosol provision devices using induction heating for flat aluminum substrates experience undesirable movement of the consumable during heating, leading to instability issues.
Innovation Solution
The aerosol provision device incorporates an aerosol generator with inductor coils where the article is interlaced or positioned between the windings, stabilizing the consumable and preventing unwanted movement by creating a mechanical cancellation effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If induction heating is used to heat flat aluminum substrates, then heating efficiency is improved, but the consumable moves in an undesirable manner leading to instability
Solution Approach 1:
The patent changes the orientation of the flat aluminum substrate from the conventional longitudinal insertion to a position between the windings of the inductor coil. This dimensional repositioning allows the substrate to be heated effectively by induction while the coil windings provide mechanical constraint from multiple directions, preventing unwanted movement and stabilizing the consumable during heating.
2Productivity
If a flat aluminum substrate is inserted into the heating zone, then aerosol generation is enabled, but the article moves undesirably during heating
Solution Approach 1:
The inductor coil windings act as an intermediary structure that simultaneously performs two functions: generating the magnetic field for induction heating to enable aerosol generation, and providing mechanical constraint to stabilize the flat aluminum substrate. The windings serve as both the heating source and the positioning mechanism, eliminating the need for separate constraint structures.
3Device complexity
If conventional longitudinal insertion is used, then device structure is simple, but inductive heating causes undesirable movement
Solution Approach 1:
The inductor coil is designed to perform multiple functions: it generates the varying magnetic field for induction heating and simultaneously provides mechanical constraint to stabilize the consumable. This multi-functionality eliminates the need for separate heating and positioning mechanisms, maintaining structural simplicity while achieving stable heating of flat aluminum substrates.
