Aerosol Device Visual Progress Indicator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol-generating devices lack effective visual indicators to convey the progression of operational phases to users, making it difficult for users to determine the remaining duration or progress of a usage session, especially when multiple parameters influence the session duration.
Innovation Solution
An aerosol-generating device equipped with a controller and indicator system that displays progress through a sequence of multiple indication states, using a visual indicator such as a lighting array with discrete light emitting units, to provide a high-resolution visual feedback on the remaining duration or progress of the usage session.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional visual indicator with limited states is used, then the device complexity is reduced, but the information precision about usage session progress is insufficient
Solution Approach 1:
The indicator comprises a predetermined number (i) of discrete light emitting units, each light emitting unit being controllable to emit light in a predetermined number (j) of different states... i being a number between 3 and 24, or 4 and 24, and j being a number between 2 and 5
Solution Approach 2:
each light emitting unit being controllable to emit light in a predetermined number (j) of different intensities or static luminance levels... progression through the first to nth indication states involves a corresponding increase or decrease in intensity or luminance of light displayed
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances user experience by providing precise and granular visual feedback on the usage session progress, allowing users to better manage their consumption and interaction with the device.
Implementation Method 1
The indicator may be a light emitting indicator comprising three or more discrete light emitting units. Each of the light emitting units is individually controllable to deliver a sequence of indication states
