Aerosol Article Marker Detection for Variable-Speed Code Reading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol generating apparatuses face challenges in reliably identifying and reading identification codes on aerosol generating articles, especially when the articles are inserted at varying speeds, leading to inaccuracies in determining the type of consumable being used.
Innovation Solution
An aerosol generating apparatus and article system that employs a sensor arrangement to detect a first marker arrangement and a second marker arrangement positioned relative to each other, allowing for the determination of data associated with the article by comparing the marker regions, ensuring accurate identification independent of insertion speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single identification code is used on the article, then the device can identify the article type, but the reading accuracy deteriorates when the article is inserted at varying speeds
Solution Approach 1:
The identification code is divided into multiple marker regions (first marker regions and second marker regions) arranged in sequences. Instead of reading a single continuous code, the system segments the code into discrete readable units that can be individually detected and compared, making the reading process less sensitive to insertion speed variations.
Solution Approach 2:
The system performs preliminary detection of multiple marker regions before final identification. By pre-detecting and storing the positions and characteristics of multiple marker regions, the system can later compare these pre-captured data points to accurately determine the identification code even if the article was inserted at varying speeds.
2Ease of operation
If the sensor reads the identification code during article insertion, then the process is simple, but the varying insertion speed causes reading inaccuracies
Solution Approach 1:
The identification process is segmented into multiple discrete marker detections rather than a single continuous read. The sensor detects individual marker regions (first marker regions and second marker regions) separately, allowing the system to reconstruct the identification code from these discrete detections regardless of the speed at which the article was inserted.
Solution Approach 2:
The system uses feedback by comparing the detected marker regions with expected patterns. The controller compares the detected first and second marker regions to determine the identification code, providing a feedback mechanism that verifies reading accuracy and compensates for variations in insertion speed.
3Measurement precision
If multiple marker regions are compared to determine identification, then the identification accuracy improves, but the device complexity increases
Solution Approach 1:
The identification system is segmented into distinct marker regions (first marker regions and second marker regions) that can be independently detected. This segmentation allows the complex task of identification to be broken down into simpler sub-tasks of detecting and comparing individual marker regions, making the overall system more manageable despite the increased number of detection points.
Solution Approach 2:
The system creates a digital copy or representation of the physical marker arrangements on the article. By detecting the positions and characteristics of marker regions and creating a digital model for comparison, the system simplifies the processing complexity while maintaining high identification precision through pattern matching against the copied marker data.
