Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision devices lack user interaction capabilities during a session, limiting control over heating profiles and energy management, which can lead to inefficient energy use and suboptimal user experience.
Innovation Solution
An aerosol provision device with a user interface that allows users to pause, alter, or change the heating profile and power mode of aerosol generators after a session has commenced, enabling temperature and duration adjustments, and automatic power saving features based on user interaction or inactivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the aerosol generators operate continuously with a fixed heating profile, then the device structure remains simple, but user control capability and energy efficiency deteriorate
Solution Approach 1:
The heating profile is made dynamic and adjustable during operation. The controller allows users to modify heating parameters (temperature, duration, intensity) in real-time during a session, transforming the static heating process into a dynamic one that adapts to user needs and conditions.
Solution Approach 2:
The system incorporates user feedback through the user interface, where users can interact to pause, resume, or alter heating profiles based on their experience. This feedback loop enables the controller to adjust heating parameters dynamically, improving user control without requiring complete system redesign.
2Use of energy by moving object
If the heating profile is fixed from the start of a session, then the device operation is simple, but energy efficiency and user experience deteriorate
Solution Approach 1:
The heating profile transitions from a fixed static pattern to a dynamic adjustable one. Users can pause heating, resume it, or modify temperature and duration parameters during the session, allowing the system to adapt energy consumption to actual usage needs and improve overall energy efficiency.
Solution Approach 2:
The system allows changing of heating parameters (temperature, duration, intensity) during operation. The controller receives user input and modifies heating profile parameters in real-time, enabling flexible energy management without complicating the basic operation through simple interface interactions.
3Loss of energy
If the device lacks pause or power saving modes, then the operational reliability is maintained, but energy consumption increases
Solution Approach 1:
The heating operation is made periodic rather than continuous. The system can pause heating for specified durations and resume when needed, creating periodic on-off cycles that reduce energy consumption while maintaining operational reliability through user-controlled resumption capability.
Solution Approach 2:
The system provides self-service power management features where users can initiate power-saving modes or pause heating when not in use. The controller automatically manages the transition between active and power-saving states based on user input, reducing energy loss without compromising the ability to resume operation when needed.

Implementation Method 1
heats smokable material to volatilize at least one component of the smokable material, typically to form an aerosol
Implementation Method 2
reduce energy or power supplied to the one or more aerosol generators so that the operational temperature of the one or more aerosol generators drops to a temperature T1

AI summary
An aerosol provision device, for generating aerosol from aerosol generating material, can include one or more aerosol generators arranged to cause aerosol to be generated from the aerosol generating material, a controller for controlling the aerosol generators, and a user interface. The user interface may be arranged so as to enable a user to interact with the user interface at a time after a session of use has commenced in order to cause the controller either: (i) to pause or alter further operation of the aerosol generators; and/or (ii) to cause the aerosol generators to enter into a power saving mode of operation; and/or (iii) to change or vary a heating profile which is set for the aerosol generators for the remainder of the session; and/or (iv) to change or vary the duration of a heating profile which is set for the aerosol generators for the remainder of the session.
