Hinged Laminate Body for Expanded Authenticity Determination Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods, such as holograms, have limited installation areas and are costly, making it difficult to increase the authenticity determination area effectively.
Innovation Solution
A hinged laminate body comprising a transparent resin layer, watermarked sheet material, and a hinge layer with a protruding hinge portion, where the watermarked sheet material includes a watermark and laser marking contiguous with the interlayer and hinge arrangement portions, and an electronic component holding layer, allowing for increased authenticity determination area without the high costs associated with holograms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a hologram is used for authenticity determination, then authenticity verification is achieved, but the installation area is limited and cost is high
Solution Approach 1:
The patent uses a watermarked sheet material that contains a watermark and laser marking as a copy or alternative representation of authenticity, replacing the need for expensive holograms. The watermarked sheet material serves as a visual copy that can be easily replicated and distributed, providing authenticity verification without the high cost of holographic technology.
Solution Approach 2:
The patent changes the parameter of authenticity determination from holographic images to watermarked sheet materials with specific visual characteristics (watermark and laser marking). This parameter change allows for a larger installation area while reducing cost, as the watermarked sheet material can be easily produced in large quantities at lower cost compared to holograms.
2Area of stationary object
If a hologram is used for authenticity determination, then authenticity verification is achieved, but the installation area is limited
Solution Approach 1:
The patent segments the authenticity determination function into separate visual elements: a watermark and a laser marking on the watermarked sheet material. This segmentation allows each element to be independently optimized and positioned to maximize the authenticity determination area without increasing overall structural complexity.
Solution Approach 2:
The patent transitions from a two-dimensional holographic image to a multi-layered structure with the watermarked sheet material positioned between the hinge layer and transparent resin layer. This dimensional change allows the authenticity determination area to be expanded across multiple layers and positions, effectively increasing the available area without proportionally increasing complexity.
3Area of stationary object
If watermarked sheet material is used throughout the laminate body, then authenticity determination area is increased, but manufacturing complexity increases
Solution Approach 1:
The watermarked sheet material serves multiple functions simultaneously: it provides authenticity determination through its watermark and laser marking, acts as a structural layer within the laminate body, and contributes to the overall design and visual appearance. This multi-functionality reduces the need for separate components, thereby limiting the increase in manufacturing complexity despite the expanded authenticity determination area.

AI summary
Provided are a hinged laminate body, a booklet, and a laminate body that are able to increase the installation area of a member for authenticity determination. A hinged laminate body is configured so as to be able to increase the installation area of a member for authenticity determination by being provided with: an upper transparent layer; watermarked paper that is arranged below the upper transparent layer; and a hinge layer that has a hinge portion protruding from the upper transparent layer in a plan view and that is arranged below the watermarked paper. The watermarked paper of the hinged laminate body is provided with: an inner watermarked paper section that is arranged between the upper transparent layer and the hinge layer; and an outer watermarked paper section that is provided to the hinge portion so as to be arranged contiguously with the inner watermarked paper section.
