Packaging Fingerprint Panel for Authentication Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaged goods are not well-suited for authentication systems due to the structure of typical packages, which prevents the unique and non-clonable properties from being conveniently and accurately imaged, leading to inefficient light illumination and imaging, thereby hindering the generation of identification codes.
Innovation Solution
A package design featuring a fingerprint panel with a diffuse transmission of light, where the illumination side is directly illuminated by a light source and the imaging side is directly imaged by a device, allowing for effective imaging of unique features representing the package's identity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light passes through a translucent package structure to illuminate the fingerprint area, then the package can be sealed and protect the product, but the light intensity is substantially reduced and the fingerprint area is poorly illuminated
Solution Approach 1:
The package is divided into separate functional areas: a translucent sealed portion for product protection and a transparent fingerprint panel for authentication. This segmentation allows each area to optimize its specific function without compromising the other.
Solution Approach 2:
Different portions of the package have different optical properties - the sealed portion remains translucent while the fingerprint area uses a transparent panel. This local differentiation enables optimal light transmission for authentication while maintaining package integrity.
2Illumination intensity
If the product is positioned within the package, then the package can contain and protect the product, but the product partially blocks the light emitted by the light source
Solution Approach 1:
The package structure separates the product containment function from the authentication function by using a dedicated transparent fingerprint panel, allowing light to reach the fingerprint area without being blocked by the product.
Solution Approach 2:
The transparent fingerprint panel acts as an intermediary between the light source and the fingerprint area, ensuring unobstructed light transmission while the product remains contained in the sealed portion of the package.
3Measurement precision
If the package structure prevents light from effectively illuminating the fingerprint area, then the package maintains its conventional sealed structure, but the authentication assembly cannot effectively image the fingerprint area
Solution Approach 1:
The package incorporates a localized transparent fingerprint panel with specific optical properties that enable effective imaging, while the rest of the package maintains its conventional sealed structure for product protection.
Solution Approach 2:
The transparent fingerprint panel serves multiple functions: it allows light transmission for illumination, enables clear imaging for authentication, and integrates seamlessly with the conventional package structure for product containment.
4Measurement precision
If the package uses translucent material for sealing, then the package can be hermetically sealed, but the unique and non-clonable properties cannot be conveniently and accurately imaged
Solution Approach 1:
The package separates the sealing function (translucent material) from the authentication function (transparent fingerprint panel), allowing each to optimize its performance without compromise.
Solution Approach 2:
The fingerprint panel uses transparent material with specific optical properties that enable accurate imaging of unique features, while the sealed portions use translucent material for product protection.
