Aerosol Refill Control for Predictable Article Life
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerosol provision systems face issues with articles becoming less reliable and unpredictable due to continuous use, leading to potential failure, as refilling with aerosol-generating material can cause degradation of components and affect user experience.
Innovation Solution
A refilling device with control circuitry that detects the article and reservoir, determining the amount of aerosol-generating material and facilitating transfer based on thresholds, while also charging the aerosol provision device and providing a desktop design with separate interfaces for efficient refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the article is continuously refilled with aerosol-generating material, then the life of the article is extended, but the reliability of the article decreases due to component degradation
Solution Approach 1:
The system performs preliminary detection of component condition and aerosol-generating material level before degradation occurs. The control circuitry monitors parameters such as heating element resistance and wick saturation to predict remaining useful life, enabling proactive refilling decisions that prevent degradation while extending article life
Solution Approach 2:
The system implements feedback control by continuously monitoring component health parameters and aerosol-generating material levels, then adjusting refilling operations accordingly. The control circuitry uses sensor data to determine optimal refilling timing and quantity, preventing over-refilling that could cause degradation while maximizing article utilization
2Productivity
If manual refilling is performed, then the article can be refilled, but the process is time-consuming and imprecise
Solution Approach 1:
The article performs self-service refilling through integrated control circuitry that automatically detects when refilling is needed and controls the refilling process. The system monitors its own aerosol-generating material levels and component status, eliminating the need for user intervention and enabling precise, automated refilling operations
Solution Approach 2:
The system replaces manual mechanical refilling operations with electronic control and automated mechanisms. The control circuitry uses electrical signals to regulate material transfer, replacing imprecise manual pouring or injection with electronically controlled dosing that ensures accurate material delivery
