Secure Article Revelation Screen Nested Image Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current secure articles lack advanced optical systems capable of producing multiple visual effects for authentication and identification, limiting their ability to differentiate between similar items, such as banknotes with the same fiduciary value, and are restricted to displaying a single imprinted image at a time.
Innovation Solution
A secure article featuring a revelation frame and a combined image with nested images of different colors, where the revelation frame comprises occulting and non-occulting elements, allowing for the observation of multiple revealed images by adjusting the angle or position, creating a colorful pattern recognizable by the naked eye and providing new authentication possibilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single imprinted image is used in secure articles, then the structure is simple and easy to manufacture, but the authentication capability is limited and cannot differentiate between similar items
Solution Approach 1:
The patent implements nested images where multiple images are superimposed on the same plane. Each nested image contains unique visual information that can be revealed by selectively obscuring portions of the combined image. This allows multiple authentication patterns to coexist in a single compact structure, enhancing authentication capability without proportionally increasing structural complexity.
Solution Approach 2:
The patent divides the combined image into multiple nested images that can be independently controlled. By using an obscuring image with transparent and opaque regions, specific nested images can be selectively revealed or hidden. This segmentation allows the system to display different authentication patterns from a single combined image structure.
2Adaptability or versatility
If multiple nested images are displayed simultaneously, then authentication capability is enhanced, but the visual complexity increases making it harder to observe and recognize patterns
Solution Approach 1:
The patent extracts and displays only the relevant nested image information at any given time by using transparent and opaque regions in the obscuring image. This selective extraction allows observers to clearly see one authentication pattern without interference from other nested images, maintaining ease of recognition while preserving multiple authentication options.
Solution Approach 2:
The patent enables dynamic switching between different nested images by moving or rotating the obscuring image relative to the combined image. This dynamic control allows the same physical structure to present different authentication patterns on demand, enhancing versatility while keeping the observer interface simple and clear at any moment.
3Adaptability or versatility
If the dimension of non-occulting screen elements is greater than nested image elements, then multiple nested images can be observed, but the precision of individual image observation is reduced
Solution Approach 1:
The patent uses non-occulting screen elements with dimensions larger than individual nested image elements, creating an intentional overlap region. This excessive dimension ensures that when the obscuring image is positioned to reveal one nested image, adjacent nested images are partially visible in the overlap region, providing context and enabling verification of multiple images simultaneously while maintaining clear observation of the primary image.
