Cartridge Refilling Control with Refill Count Expiration Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol provision systems, such as e-cigarettes, face issues with the reliability and predictability of reusable cartridges due to degradation of components over time, leading to reduced performance and potential failure, as they are often limited by the life of consumable aerosol-generating materials rather than the cartridge's capacity, and existing refilling solutions lack effective authentication and expiration tracking.
Innovation Solution
A refilling device equipped with refilling control circuitry that facilitates the transfer of aerosol-generating material from a reservoir to a cartridge, updates a counter to track refills, determines cartridge authenticity and expiration, and prevents further refilling when expired, while also providing notifications to the user through a connected system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the article is refilled multiple times to extend its life, then the productivity is improved, but the reliability deteriorates due to component degradation
Solution Approach 1:
The system performs preliminary actions by tracking the refill count and predicting component failure before it occurs. The machine learning model analyzes usage patterns and predicts when components will fail, allowing the system to proactively manage article lifecycle and notify users before reliability issues arise.
Solution Approach 2:
The system implements continuous feedback loops by monitoring article usage, updating refill counts, and using machine learning models to analyze performance data. This feedback mechanism allows the system to adaptively manage article lifecycle, adjusting refilling recommendations based on predicted component reliability.
2Productivity
If refilling is allowed without restrictions to extend article life, then the productivity is improved, but harmful factors increase due to degraded components
Solution Approach 1:
The system performs preliminary analysis of component degradation trends using machine learning models before harmful degradation products accumulate to dangerous levels. By predicting component failure and degradation patterns in advance, the system can alert users to replace articles before harmful substances are generated.
Solution Approach 2:
The patent replaces traditional mechanical/refilling-based lifecycle management with an intelligent system using machine learning models and sensors. This substitution enables the system to detect and respond to component degradation through data analysis rather than simple refill counting, preventing harmful degradation products by predicting failure modes.
3Reliability
If authentication mechanisms are added to verify article authenticity, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The system implements multi-functional authentication mechanisms that serve multiple purposes: verifying article authenticity, tracking refill counts, and collecting usage data for machine learning models. By combining these functions into a single integrated system, the patent reduces overall complexity while maintaining reliable authentication.
Solution Approach 2:
The patent uses intermediary elements such as RFID tags, NFC chips, or coded identifiers embedded in articles that facilitate authentication without requiring complex verification systems in the refilling device. These intermediaries carry authentication data that can be read and verified through simple communication protocols.

AI summary
A refilling device for an article of an aerosol provision system comprises refilling control circuitry. The refilling control circuitry is configured to facilitate the transfer of aerosol-generating material from a reservoir coupled to the refilling device to the article and cause a value of a counter to be updated in response to the transfer of the aerosol- generating material.. The value of the counter indicative of a number of times the article has been refilled. The refilling control circuitry determines if the article is expired based on a comparison between the updated value of the counter and a refill limit and writes data to computer-readable memory indicating that the article is expired in response to determining that the article is expired.
