Textile Connecting Strap Penetrating Data Page Print for Passport Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional passport book constructions are not sufficiently secure against the exchange of data pages, making it difficult to detect manipulation, and complex materials and processes are required for existing solutions.
Innovation Solution
A data carrier with a connecting strap made of textile material that overlaps and penetrates the data page's printing, ensuring that any tampering or manipulation is visible by damaging the printing, thus making it irreversible and detectable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a plastic card is sewn into a passport book using a textile connecting flap, then the card can be turned over like a normal page, but the construction is not sufficiently secure against data page exchange and manipulation detection is difficult
Solution Approach 1:
The patent applies foil printing that changes appearance under different lighting conditions (iridescent, holographic effects) directly on the data page. This creates visible security features that are difficult to replicate and can detect manipulation through changes in color, brightness, or pattern when viewed from different angles or under different light sources.
Solution Approach 2:
The data page is constructed as a composite of multiple layers including foil-printed layers, plastic substrates, and textile connecting flaps. This multi-layer composite structure integrates security features directly into the data page itself, making manipulation detection easier while maintaining the flexibility needed for turning pages.
2Reliability
If complex multilayer structures with coextruded strip films are used to create a data carrier, then security features can be integrated, but the manufacturing process becomes complex and difficult to produce
Solution Approach 1:
The patent combines multiple functions into the data page itself: the security foil printing, the structural plastic layer, and the connecting flap are integrated into a single manufacturable unit. This reduces the number of separate manufacturing steps and assemblies required while maintaining integrated security features.
Solution Approach 2:
The patent uses foil printing techniques that can be applied directly to the data page surface, changing the optical parameters (reflectivity, color, pattern) without requiring complex multilayer coextrusion processes. This simplifies manufacturing while achieving the same security effect.
3Ease of manufacture
If conventional passport constructions are used, then production is simpler, but security against data page exchange and manipulation detection is insufficient
Solution Approach 1:
The patent applies iridescent and holographic foil printing directly to the data page, creating security features that change color and appearance based on viewing angle and lighting conditions. This provides enhanced security against forgery while maintaining compatibility with conventional manufacturing processes.
Solution Approach 2:
The security foil printing is applied to the data page during the initial manufacturing process rather than as a separate post-processing step. This preliminary integration of security features simplifies production while ensuring that security measures are built into the document from the start.

AI summary
In order to protect against manipulation by detaching a data carrier (300) from a booklet- or book-shaped object (20) into which the data carrier is inserted, the data carrier (300) according to the invention is formed by a data side (100) and a connecting link (200) connected to the data side in an edge overlap region (310), wherein the connecting link (200) has a textile material (210) and the data side (100) contains a print (180), wherein the print (180) also extends into the overlap region (310) and wherein the textile material (210) touches the print (180) and/or completely or partially penetrates the print.
