Security Document Data Sheet with Flexible Paper Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security and/or valuable documents face issues with insufficient flexibility of the flap, leading to a 'folding-open' situation and potential delamination between layers, which complicates production and requires expensive modifications.
Innovation Solution
A data sheet formed of at least two stacked layers of organic polymeric material with a flexible paper material layer coated with an organic binding agent, creating a highly flexible flap that serves as a hinge and ensures a secure connection between layers, allowing for simple production and integration into documents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a textile fabric flap is used in the data sheet, then the connection between flap and polymeric layers is achieved, but the flexibility is insufficient causing folding-open situation
Solution Approach 1:
The patent changes the material parameter from textile fabric to paper material, fundamentally altering the flexibility characteristics while maintaining the connection function through the organic binding agent coating
Solution Approach 2:
The invention creates a composite structure where paper material layer is coated with organic binding agent to achieve both flexibility and secure connection to polymeric layers
2Strength
If expensive thermoplastic plastic layer is used with textile core layer, then connection is achieved, but production becomes complex and expensive
Solution Approach 1:
The patent replaces expensive thermoplastic plastic layers with a more economical paper material layer that achieves the same functional purpose through coating with organic binding agent
Solution Approach 2:
The invention changes the material composition and processing parameters, using paper material with organic binding agent coating instead of expensive thermoplastic materials, simplifying the manufacturing process
3Strength
If fabric material like polyester is used for flap, then firm connection is achieved, but expensive cut-outs are required
Solution Approach 1:
The patent replaces fabric material with paper material that achieves firm connection through chemical coating with organic binding agent, eliminating the need for complex mechanical cut-outs
Solution Approach 2:
The invention substitutes mechanical connection methods (cut-outs) with chemical bonding through organic binding agent coating on the paper material layer
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 solution provides a highly flexible flap that prevents document folding-open and ensures a stable connection, enhancing openability and reducing blocking tendencies while simplifying production and integration into security documents.
Implementation Method 1
The paper material layer is coated and/or wet through on one or both sides at least in the region between the layers at least partially with an organic binding agent and is bonded with the two layers by means of the binding agent
Data Source
AI summary
The invention relates to a data sheet (1) for integration in a preferably book-like security and/or valuable document, wherein the data sheet (1) is formed of at least two stacked layers (2, 3) of an organic polymeric material, wherein at least in a partial section between the layers (2, 3) and outside of the layers (2, 3), a paper material layer (5) forming a flap (4) is disposed, and wherein the paper material layer (5) is coated and/or wet through on one or both sides at least in the region between the layers (2, 3) at least partially with an organic binding agent (6), and is bonded with the two layers (2, 3) by means of the binding agent (6).
