Book-like Document Welding for Forgery-Resistant Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for producing book-like documents, such as identification documents, are time-consuming and material-intensive due to the need for sewing or punching threads, which also pose challenges in maintaining security against forgery.
Innovation Solution
A book-like document is produced using data pages connected to the book cover through welding or lamination, eliminating the need for mechanical connecting elements and allowing for a sutureless binding process, with welds or adhesive points forming inseparable connections to enhance security against manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sewing or punching with threads is used to bind data pages to the book cover, then the binding is secure and reversible, but the production time increases and material consumption increases
Solution Approach 1:
The patent replaces the mechanical sewing/punching system with a thermal welding system. Instead of using needles and threads to mechanically join data pages to the book cover, the invention uses heat-induced welding to fuse the plastic coating on data pages directly to the book cover, eliminating the need for mechanical connecting elements and significantly reducing production time
Solution Approach 2:
The invention changes the binding method from mechanical (reversible) to thermal (irreversible). By applying heat to weld the plastic-coated data pages to the book cover, the binding becomes permanent and inseparable, which increases security against forgery while reducing production time and material consumption
2Ease of manufacture
If sewing or punching with threads is used to bind data pages to the book cover, then the binding can be reversed for manipulation, but the production time increases and material consumption increases
Solution Approach 1:
The patent replaces the mechanical sewing/punching system with a thermal welding system. Instead of using needles and threads to mechanically join data pages to the book cover, the invention uses heat-induced welding to fuse the plastic coating on data pages directly to the book cover, eliminating the need for mechanical connecting elements and significantly reducing production time
Solution Approach 2:
The invention changes the binding method from mechanical (reversible) to thermal (irreversible). By applying heat to weld the plastic-coated data pages to the book cover, the binding becomes permanent and inseparable, which increases security against forgery while reducing production time and material consumption
3Productivity
If welding or lamination is used to permanently connect data pages to the book cover, then security against forgery increases and production time decreases, but the connection becomes inseparable
Solution Approach 1:
The invention changes the binding method from mechanical (reversible) to thermal (irreversible). By applying heat to weld the plastic-coated data pages to the book cover, the binding becomes permanent and inseparable, which increases security against forgery while reducing production time and material consumption
Solution Approach 2:
The patent replaces the mechanical sewing/punching system with a thermal welding system. Instead of using needles and threads to mechanically join data pages to the book cover, the invention uses heat-induced welding to fuse the plastic coating on data pages directly to the book cover, eliminating the need for mechanical connecting elements and significantly reducing production time
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
This method significantly reduces production time and material consumption while maintaining or increasing security against forgery by creating a non-detachable connection that is optically recognizable if tampered with.
Implementation Method 1
The folded edge of the at least one data page and the folded edge in the folded area of the book cover are permanently connected to one another without mechanical connecting elements. Only one or more welds or adhesive points are provided for this purpose along the folded edge in the folded area of the data page and the book cover to form the connection point.
Implementation Method 2
The data pages are connected to one another by lamination or welding to form a book block and the book block is permanently bound into the book cover.

AI summary
The invention relates to a book-like document, in particular an identification document, and to a method for producing same. The document comprises a book binder (12) and multiple data pages (17, 18). The book binder (12) has a fold region (35), and the data pages (17, 18) are bound into the fold region (35) of the book binder (12) in a non-detachable manner at least in some regions by means of a welding or laminating process.
