Problem
Existing electronic aerosol provision systems face issues with waste generation due to disposable articles and potential misuse of refillable consumables, along with challenges in convenient and safe refilling processes, especially with aerosol-generating materials like liquid nicotine.
Innovation Solution
A refilling unit and system that includes an article port, information reader, and controller to manage refilling based on actual and expected usage, ensuring safe and efficient transfer of aerosol-generating material, while preventing misuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual refilling is used, then user control and flexibility are improved, but alignment accuracy and spillage prevention deteriorate
Solution Approach 1:
The docking station serves as an intermediary device between the refill bottle and the cartridge. It provides a controlled environment with alignment guides and transfer mechanisms that automatically position components correctly, eliminating the alignment problems of manual refilling while maintaining user control through the automated process.
Solution Approach 2:
The system enables self-service refilling where the user simply places the bottle and cartridge in the docking station, and the system automatically performs the refilling process without requiring manual alignment or operation, combining ease of operation with precise alignment.
2Ease of operation
If disposable articles are used, then convenience and safety are improved, but waste generation deteriorates
Solution Approach 1:
Instead of discarding the entire cartridge after use, the system separates the depleted cartridge from the refillable bottle. The cartridge can be discarded or recycled, while the bottle is recovered and refilled for multiple uses, reducing waste while maintaining convenience.
Solution Approach 2:
The system divides the aerosol provision system into separable components: a disposable or recyclable cartridge and a refillable bottle. This segmentation allows the bottle to be reused multiple times while only the cartridge is discarded, significantly reducing waste compared to fully disposable units.
3Loss of substance
If refillable consumables are used, then waste reduction is improved, but system reliability and safety deteriorate
Solution Approach 1:
The docking station acts as an intermediary that verifies and controls the refilling process. It can include sensors and control mechanisms to ensure that only compatible, regulated materials are transferred into approved containers, maintaining system reliability while enabling refillable usage.
Solution Approach 2:
The system incorporates feedback mechanisms through the docking station that can detect the type of material being refilled, the state of the cartridge, and the refilling progress. This feedback ensures that refilling only occurs under safe and appropriate conditions, maintaining reliability while enabling waste reduction through reuse.

AI summary
A refilling unit for refilling a refillable article for use with an aerosol provision device for generating aerosol from aerosol-generating material stored within the refillable article, the refilling unit including: an article port for receiving at least the article; an information reader configured to read a readable element for storing information corresponding to the article; and a controller for controlling operations of the refilling unit, wherein the controller is configured to: determine or obtain an actual usage of the article based on an indication of usage of the article read from the readable element; determine or obtain an expected usage of the article; and compare the actual usage with the expected usage and, if the actual usage is within a predetermined range of the expected usage, permit the refilling unit to refill the article with aerosol-generating material. Also described is an article, aerosol provision device, system and method.
