Aerosol Apparatus Marker Authentication and Dynamic Heating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generation technologies, such as 'heat-not-burn' products and e-cigarettes, face challenges in accurately identifying and authenticating aerosolisable medium articles, leading to potential counterfeit usage and inconsistent user experiences due to varying characteristics of the aerosolisable medium, such as tobacco blends, and insertion rate variations affecting sensor accuracy.
Innovation Solution
An apparatus with a housing, heating chamber, and controller that includes sensors to detect a marker on the aerosolisable medium article, determining its parameter and rate of movement to authenticate and tailor the heating profile, preventing counterfeit usage and optimizing the aerosol generation process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are used to detect markers on aerosolisable medium articles for authentication, then counterfeit prevention is improved, but measurement precision deteriorates due to varying insertion rates affecting sensor accuracy
Solution Approach 1:
The system dynamically adjusts the heating profile and authentication criteria based on the detected insertion rate. The controller modifies operational parameters in real-time to compensate for variations in insertion speed, ensuring that marker detection remains accurate regardless of how fast or slow the article is inserted into the chamber.
Solution Approach 2:
The system changes detection parameters based on the measured insertion rate. By adjusting sensitivity thresholds, detection windows, and heating temperatures according to the insertion speed, the system maintains measurement precision across varying operational conditions while continuing to effectively prevent counterfeit usage.
2Ease of operation
If heating profiles are tailored based on detected article parameters, then user experience is improved, but device complexity increases due to additional control mechanisms
Solution Approach 1:
The system automatically determines article parameters from detected markers and self-adjusts the heating profile without requiring user input or manual configuration. The controller autonomously selects appropriate heating parameters based on the authenticated article type, simplifying operation for the user while managing complexity internally within the control system.
3Reliability
If authentication based on marker detection is implemented, then genuine aerosolisable medium usage is ensured, but device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The sensor system serves multiple functions: it detects the marker for authentication, measures the insertion rate for dynamic compensation, and provides data for heating profile selection. By making the sensor system multi-functional, the patent reduces the need for separate dedicated components, thereby limiting the increase in device complexity while maintaining robust authentication capabilities.
