Inner Tube Aperture Coding for Secure Aerosol Article Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods for aerosol-generating articles, such as heat-not-burn devices, are prone to being easily replicated and lack robustness, especially when exposed to heat, and require additional indicia that complicate the manufacturing process.
Innovation Solution
An authentication system using apertures in the inner tube of the aerosol-generating article, which are arranged to form a machine-readable pattern, allowing identification without visible indicia, and detected through light transmission and scattering properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If visible indicia (barcodes, codes) are arranged on the outer surface of the article for authentication, then the identification capability is improved, but the manufacturing process complexity increases and the codes can be easily copied or altered
Solution Approach 1:
The patent extracts the authentication information from the outer surface and relocates it to the inner tube structure. The machine-readable pattern is formed by apertures in the inner tube wall, which are invisible from the outside, thereby removing the need for visible indicia on the article surface and simplifying manufacturing.
Solution Approach 2:
The inner tube acts as an intermediary carrier for the authentication code. Instead of placing codes directly on the outer surface where they are vulnerable to copying, the code is embedded in the inner tube structure, using the tube itself as the medium that conveys authentication information securely.
2Reliability
If codes are arranged on the outer surface for authentication, then identification is enabled, but the codes are easily visible and can be replicated by human eye
Solution Approach 1:
Instead of making the code visible on the outer surface for easy detection, the patent inverts the approach by making the code invisible. The machine-readable pattern is formed by apertures in the inner tube that are not detectable by human eye, requiring specialized optical detection systems.
Solution Approach 2:
The inner tube serves as a flexible barrier that contains the authentication code. The tube wall with apertures provides a protective barrier that prevents direct viewing of the code while still allowing optical detection through the apertures when illuminated.
3Reliability
If visible indicia are applied to the article surface, then authentication information is provided, but the indicia may be altered or damaged by heat exposure
Solution Approach 1:
The patent extracts the authentication code from the outer surface layer that is exposed to heat and relocates it to the inner tube structure. The inner tube, being part of the core structure rather than an outer coating, is better protected from heat exposure and environmental factors that could alter or damage visible indicia.
4Loss of information
If traditional barcodes are used for authentication, then identification is possible, but the information density is low and easily copied
Solution Approach 1:
The patent transitions from traditional 2D surface codes to a 3D structural code embedded in the inner tube. The machine-readable pattern is formed by the arrangement of apertures in the tube wall, utilizing the third dimension (depth/thickness) to encode information, thereby increasing information density and making copying more difficult.
