Laser-Formed Lens Structure for Readable ID Security Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personalized plastic identification documents lack effective security features that allow for clear visibility and readability of security elements without the need for additional tools, making them susceptible to counterfeiting and fraudulent use.
Innovation Solution
Incorporation of a lens structure with a plurality of lenses formed using a laser on the document to facilitate viewing and reading of security features, such as text or images, which are embedded beneath the lens structure, enabling visibility and readability with the naked eye.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security features are printed directly on the document without a lens structure, then the document structure remains simple and manufacturing is easier, but the security features are not visibly discernible or readable to the naked eye
Solution Approach 1:
A lens structure is introduced as an intermediary element between the security feature printing layer and the observer's eye. This lens structure magnifies and makes readable otherwise invisible printed text and images, resolving the contradiction by enabling visibility without making the underlying security features more complex.
Solution Approach 2:
The solution adds a third dimension by incorporating a lens structure that protrudes from or is integrated into the document surface. This dimensional addition allows the security features to be viewed through magnification, transforming invisible 2D printed information into visible magnified images without complicating the base document structure.
2Reliability
If a lens structure is added to make security features visible, then security against counterfeiting is improved, but the manufacturing process becomes more complex
Solution Approach 1:
The lens structure is merged with existing document components such as the protective laminate or window elements. By combining the lens function with already-present structural elements, the anti-counterfeiting capability is enhanced without requiring entirely new manufacturing processes or additional separate components.
3Ease of operation
If security features are made visible through a lens structure, then readability to the naked eye is improved, but additional processing steps are required
Solution Approach 1:
The lens structure is pre-formed and positioned on the document during the personalization process, before the security features are printed. This preliminary preparation allows the security features to be printed directly in their final visible positions, eliminating the need for post-printing adjustments or additional processing steps to achieve readability.
