Aerosol Provision Device with Multi-Unit Heating Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision devices, such as tobacco heating products, struggle to efficiently heat aerosolizable materials without burning them, leading to inconsistent aerosol quality and user experience.
Innovation Solution
The device incorporates a heating apparatus with multiple heating units and a controller that independently controls each unit to heat different portions of the aerosolizable material at varying temperatures, ensuring that each portion is aerosolized without burning, and that the aerosol is generated from 'fresh' material throughout the heating session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a single heating zone is used to heat aerosolizable material, then the device structure is simple, but the heating is不均匀 leading to burning and poor aerosol quality
Solution Approach 1:
The heating zone is divided into multiple independently controllable heating units (first heating unit, second heating unit, third heating unit) positioned at different locations. Each heating unit can be controlled separately to heat different portions of the aerosolizable material, ensuring uniform heating and preventing burning while maintaining simple overall device structure.
Solution Approach 2:
Different portions of the aerosolizable material are heated to different temperatures by different heating units. The first portion is heated to a first temperature, the second portion to a second temperature, and the third portion to a third temperature, allowing each region to be optimized for its specific function while maintaining overall system simplicity.
2Manufacturing precision
If multiple heating units are used to heat different portions of material, then aerosol quality is improved, but heating session duration is limited by the first portion
Solution Approach 1:
The first heating unit heats the first portion of the aerosolizable material before the second and third heating units operate. This preliminary heating ensures that the first portion is ready for aerosol generation, while the second and third portions are heated in parallel afterward, extending the overall heating session duration.
Solution Approach 2:
The controller coordinates the heating units to operate in a continuous sequence: the first heating unit operates first, then the second heating unit operates while the first heating unit may be deactivated, and finally the third heating unit operates. This continuous coordination ensures uninterrupted aerosol generation from fresh material throughout the heating session.
3Temperature
If the first heating unit operates continuously, then the first portion is heated thoroughly, but energy is wasted when not needed
Solution Approach 1:
The controller coordinates the heating units to operate in periodic sequences rather than continuously. The first heating unit operates during a first period, then may be deactivated while the second heating unit operates during a second period, and the third heating unit operates during a third period. This periodic operation ensures thorough heating when needed while avoiding energy waste during transitions.
Solution Approach 2:
The controller monitors the heating process and coordinates the heating units based on feedback from temperature sensors and material state. When the first portion is sufficiently heated, the controller deactivates the first heating unit and activates the second heating unit, optimizing energy usage while maintaining required temperature levels.

AI summary
An aerosol provision device having a heating zone for receiving at least a portion of an article including aerosolizable material, an outlet through which aerosol is deliverable from the heating zone to a user in use, and heating apparatus for causing heating of the article when the article is at least partially located within the heating zone to thereby generate the aerosol. The heating apparatus is configured to, during a heating session, cause heating of a first portion of the aerosolizable material to a temperature sufficient to aerosolize a component of the first portion of the aerosolizable material, and heating of a second portion of the aerosolizable material to a temperature sufficient to aerosolize a component of the second portion of the aerosolizable material. The heating apparatus is configured to cause the heating of the first portion before or more quickly than the heating of the second portion.
