Security Vignette with Folded Sub-Elements for Anti-Forgery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security vignettes for vehicles lack forgery-proof and tamper-proof features, and current methods for individualization are not secure against misuse, as they can be easily manipulated or transferred between vehicles.
Innovation Solution
A system and method for producing a security element, such as a vignette, with a carrier element having two sub-elements that overlap and are glued together, where the second sub-element has a greater width and includes an individualization feature applied on its side, which is protected within the layer structure, making it inaccessible for manipulation, and features like relief structures and reflection layers enhance security against forgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If individualization features are applied externally to vignettes, then ease of individualization is improved, but security against manipulation deteriorates
Solution Approach 1:
The vignette is divided into multiple sub-elements (first sub-element with individualization feature, second sub-element with adhesive) that are separately prepared and then combined through folding and gluing. This segmentation allows the individualization feature to be applied early on the first sub-element while the final security structure is completed during assembly, resolving the contradiction between ease of individualization and security against manipulation.
Solution Approach 2:
The first sub-element containing the individualization feature is nested within the layered structure formed by folding the carrier element and gluing to the second sub-element. The individualization feature becomes embedded within the security element structure, protecting it from manipulation while maintaining ease of application during the manufacturing process.
2Ease of operation
If vignettes can be detached and transferred between vehicles, then ease of operation is improved, but security against misuse deteriorates
Solution Approach 1:
The vignette is segmented into sub-elements with specific functional zones: the second sub-element has adhesive positioned such that when folded and glued, it creates both easy attachment capability and anti-theft security features. The adhesive arrangement allows legitimate removal and reattachment while preventing unauthorized transfer through manipulation detection features.
Solution Approach 2:
Different regions of the vignette have different properties: the adhesive area provides ease of attachment, while specific security features (relief structures, optical elements) in localized areas provide tamper evidence and anti-theft protection. This local differentiation resolves the contradiction between ease of operation and security against misuse.
3Reliability
If security features are added to prevent forgery, then reliability is improved, but device complexity deteriorates
Solution Approach 1:
The vignette uses composite structures combining different materials and features: carrier element, sub-elements with adhesive, relief structures, and optical security features are integrated into a unified security element. This composite approach provides robust anti-forgery protection while maintaining a relatively simple overall structure that can be manufactured efficiently.

AI summary
The invention relates to a system (100, 200, 300, 400, 500, 600) for producing a security element (4), in particular a vignette for a windshield pane (6) of a transportation means. The security element comprises a support element (3) with a first and a second surface, wherein a first sub-element (1) of the security element (4) is arranged in a first region (31) of the first surface, and a second sub-element (2) of the security element (4) is arranged in a second region (32) of the first surface, said second region being separated from the first region (31) by a folding edge (33). The sub-elements (1, 2) can be brought into a stacked arrangement by folding the support element (3) along the folding edge (33) and can be adhered by means of an adhesive (25) arranged on the second sub-element (2) face facing away from the support element (3). An individualizing feature (14) can be applied onto a first (1) and/or second sub-element (2) face facing away from the support element (3). The invention further relates to a method for producing a security element (4) using such a system (100, 200, 300, 400, 500, 600) and to a security element (4) obtained using said method.
