Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security elements for papers of value and security objects lack sufficient protection against forgery, as they do not provide a high enough combination and design variety to effectively deter counterfeiting.
Innovation Solution
A security element with at least one first region featuring structures that reflect an image motif in different spatial regions, creating a moving image when a light source is moved or the viewing angle is changed, combined with an optical effect layer that enhances the design variety and authenticity verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional security elements are used, then manufacturing is simpler, but protection against forgery is insufficient
Solution Approach 1:
The security element is divided into multiple functional regions: a first region containing structures that reflect image motifs and a second region containing an optical effect layer. This segmentation allows each region to provide specific security functions while collectively enhancing overall anti-forgery protection without requiring complete redesign of the entire element.
Solution Approach 2:
The patent combines two distinct security features (moving image structures and optical effect layer) into a single integrated security element. The optical effect layer is positioned to overlap with the first region, merging visual security features into one component that provides enhanced protection while maintaining manageable complexity through functional integration.
2Adaptability or versatility
If multiple security features are integrated, then design variety increases, but manufacturing complexity increases
Solution Approach 1:
The optical effect layer introduces a new dimensional aspect to the security element by adding optical properties (color shifts, iridescence) that vary with viewing angle and lighting conditions. This dimensional addition enhances design variety and security verification capabilities without requiring complex structural modifications in the planar dimensions, thereby managing manufacturing complexity.
Solution Approach 2:
Different regions of the security element are assigned distinct optical and visual properties: the first region contains structures for reflecting image motifs while the second region contains the optical effect layer for color-shifting effects. This local differentiation allows each region to be optimized for its specific function while maintaining overall manufacturing feasibility through modular production approaches.
3Ease of operation
If visual inspection is sufficient for verification, then ease of operation improves, but measurement precision may be compromised
Solution Approach 1:
The optical effect layer incorporates materials that exhibit color-shifting properties when viewed from different angles or under varying lighting conditions. This dynamic color change provides multiple verifiable characteristics that can be assessed through simple visual inspection, maintaining ease of operation while enhancing detection precision through multi-parameter optical verification.
Solution Approach 2:
The security element incorporates dynamic visual features including moving images that respond to light source movement and optical effects that change with viewing angle. These dynamic characteristics provide multiple states for verification, allowing observers to assess authenticity through simple visual inspection across different conditions, thereby maintaining ease of operation while improving detection accuracy through multiple observable parameters.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The integration of moving images and optical effects within the security element significantly increases protection against forgery, allowing for quick and secure authenticity verification by visual inspection without the need for aids.
Implementation Method 1
the structures reflect an image motif in different spatial regions, such that a moving image is produced for an observer when a light source is moved correspondingly and/or when a viewing angle is changed
Implementation Method 2
when the light source is moved and/or when the viewing angle is changed, a color-shifting effect occurs in the optical effect layer formed as a color-shifting layer or in the color-shifting ply
Data Source
AI summary
A security element with increased protection against forgery includes at least one first region with structures that reflect an image motif in different spatial regions, such that a moving image is produced for an observer when a light source is moved correspondingly and/or when the viewing angle is changed. When the light source is moved and/or the viewing angle is changed, a movement of the image motif occurs at the same time. Furthermore, an optical effect layer is provided which defines a second region. The optical effect layer is formed as a thin-layer element, wherein the structures are covered by the optical effect layer over their entire surface or partially.
