Aerosol Device Colour Differentiation via Ambient Light Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol-generating devices and systems lack a means to differentiate themselves from their surroundings and other devices, leading to confusion and increased likelihood of being forgotten or misplaced.
Innovation Solution
Incorporation of optical sensors and light-emitting elements that detect ambient light and emit light based on a calculated color distance to enhance contrast and provide customizable color differentiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If colour is used to indicate different functional aspects of the device, then user guidance and ease of operation are improved, but the device structure becomes more complex due to multiple coloured components
Solution Approach 1:
The patent applies color coding to different functional components of the aerosol-generating device. The mouthpiece assembly includes a first color (e.g., blue) indicating its function, while the cartridge assembly includes a second color (e.g., red) indicating its function. This visual differentiation guides users in correctly assembling and operating the device, improving ease of operation without requiring complex mechanical guidance systems.
2Adaptability or versatility
If multiple assemblies are detachably connected to form a complete device, then adaptability and ease of cleaning are improved, but the device structure becomes more complex
Solution Approach 1:
The aerosol-generating device is divided into multiple detachable assemblies including a mouthpiece assembly, cartridge assembly, and battery assembly. Each assembly can be separately removed, cleaned, or replaced. The mouthpiece assembly detaches from the cartridge assembly, and the battery assembly detaches from the cartridge assembly, allowing for modular configuration and easier maintenance while maintaining overall device functionality.
3Reliability
If a heating element is contained within a cartridge assembly, then manufacturing precision and reliability are improved, but the device structure becomes more complex
Solution Approach 1:
The heating element is contained within a separate cartridge assembly that can be detached from the mouthpiece assembly. This segmentation isolates the heating element in its own protective housing with a sealed interface, improving reliability by preventing contamination and ensuring proper thermal contact, while the modular structure avoids integrating the heating element into the main device body.

AI summary
An aerosol-generating device or system includes one or more optical sensors, one or more light-emitting elements, and a controller. The one or more optical sensors may detect a colour of ambient light and the one or more light-emitting elements may emit light. The controller may be configured to receive the signal indicative of the colour of ambient light from the one or more optical sensors, determine an ambient colour value, generate a plurality of generated colour values, determine a colour distance between the ambient light value and each of the plurality of generated colour values, select one of the plurality of generated colour values based on a plurality of colour distances, and cause the one or more light-emitting elements to emit light having a colour corresponding to the selected one of the plurality of generated colour values.
