Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic cigarettes and low-temperature heating cigarettes rely on barcodes for anti-counterfeiting and information storage, which are limited by environmental factors and have small information capacity, and require a flat surface for recognition.
Innovation Solution
An aerosol-generating article with a magnetic recording medium for information storage, integrated into the article body, and an aerosol-generating device with a magnetic head for reading this information, allowing for flexible placement and higher storage capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If barcode is used for information storage and anti-counterfeiting, then the implementation is simple and cost-effective, but the information storage capacity is limited and recognition is affected by environmental factors
Solution Approach 1:
The patent replaces the optical recognition system (barcode) with a magnetic field-based recognition system. The magnetic recording medium stores information that can be read by a magnetic head, eliminating the need for optical scanners and improving both information capacity and environmental robustness.
Solution Approach 2:
The patent changes the physical parameter used for information storage from optical (barcode) to magnetic (magnetic recording medium). This parameter change enables higher information density and removes environmental constraints on recognition, as magnetic fields are not affected by lighting or surface conditions.
2Adaptability or versatility
If barcode is printed on flat surface, then the recognition is straightforward, but the application is limited to flat surfaces only
Solution Approach 1:
The patent uses a magnetic recording medium that can be applied as a thin film or coating on the article body surface. This flexible medium can conform to curved or irregular surfaces, enabling information storage on three-dimensional objects while maintaining manufacturing simplicity.
3Reliability
If optical recognition system is used to read barcode, then the system is simple to implement, but the recognition is limited by environmental factors
Solution Approach 1:
The patent replaces the optical recognition system with a magnetic field-based system. The magnetic head reads information from the magnetic recording medium through magnetic field interaction, which is not affected by environmental factors such as lighting, dust, or surface texture, thereby significantly improving recognition reliability.
