Solution Overview
Problem
Current security elements for data carriers, such as banknotes and documents, lack enhanced protection against forgery, particularly in visual effects that depend on viewing angle, which can be reproduced by modern copiers.
Innovation Solution
A security element with a first dynamic motif created by magnetically oriented magnetic pigments and a second dynamic motif formed by a see-through area with perforations, providing increased recognition value and counterfeit security through coordinated movement effects in incident and transmitted light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If magnetically alignable effect pigments are used to create visual effects that depend on viewing angle, then the security element provides protection against forgery, but modern copiers can still reproduce these effects
Solution Approach 1:
The security element is divided into two distinct motifs: a first motif created by magnetically oriented effect pigments and a second motif created by see-through areas with perforations. This segmentation creates multiple layers of security features that work together to prevent forgery while maintaining visual appeal.
Solution Approach 2:
The patent combines two different security mechanisms (magnetic pigments and perforated see-through areas) into a single security element. The coordination of movement effects between the first and second motifs creates a composite security feature that is difficult to reproduce, as it requires simultaneously replicating both the magnetic alignment effect and the perforation pattern.
2Reliability
If a see-through area with perforations is added to create a second dynamic motif, then recognition value and counterfeit security are increased, but the device complexity increases
Solution Approach 1:
The see-through areas with perforations serve multiple functions: they create the second dynamic motif, provide see-through effects in both incident and transmitted light, and coordinate their movement with the first motif to enhance overall security. This multi-functionality justifies the increased structural complexity.
Solution Approach 2:
The patent introduces a new dimension of security by adding see-through effects in transmitted light to the traditional reflective effect of magnetic pigments. This dimensional addition creates a more complex security feature that requires viewing from different angles and lighting conditions, thereby increasing counterfeit security.
3Adaptability or versatility
If the first motif reflects multiple different image motifs to create a tilting or moving image, then the security element provides dynamic visual effects, but the manufacturing precision requirements increase
Solution Approach 1:
The patent utilizes changes in viewing angle and lighting conditions as parameters to create dynamic visual effects. The magnetic pigments and perforations are designed to respond to these parameter changes, creating tilting or moving images without requiring complex active mechanisms, thereby managing manufacturing precision requirements.
Solution Approach 2:
The first motif is designed to reflect two or more different image motifs in different spatial areas, creating asymmetric visual effects that change with viewing angle. This asymmetry enhances the dynamic visual impact while the coordination with the symmetric second motif (perforations) provides a balancing structural element.

AI summary
The invention relates to a security element for security papers, valuable documents and other data carriers which consists of a substrate having a front side and a rear side, wherein a color layer comprising magnetically aligned magnetic pigments is applied to at least one side of the substrate, said pigments forming a first motif in the form of patterns, characters or a coding, wherein the first motif exhibits a first dynamic movement effect when the security element is tilted, wherein the first dynamic motif is combined with a second motif, wherein the second motif is applied to at least one side of the substrate. The invention furthermore relates to a method for producing a corresponding security element. According to the invention, the second motif is formed by a see-through region in the security element, wherein the see-through region is formed by at least one perforation. A perforation is a region with a reduced thickness of the substrate or complete removal of the substrate. A perforation is thus a partial material removal of the substrate or else a hole in the substrate. In this case, a motif region having a visual impression that is altered in reflected light and/or transmitted light is arranged within the see-through region, said motif region exhibiting a second dynamic movement effect.
