Card Edge Transparent Section Asymmetry for Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security documents lack effective features to prevent counterfeiting, as existing methods do not provide a non-fully framed transparent security feature that adequately protects against forgery.
Innovation Solution
A card with a non-transparent card base and a transparent material section that forms part of the card edge, which can be either partially or fully transparent, offering increased security through asymmetry and haptic differentiation, and is embedded with a material boom for enhanced lamination and composite strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a transparent security feature is completely framed by opaque material, then the card structure is stable and manufacturing is simple, but the counterfeiting security is insufficient
Solution Approach 1:
The patent applies asymmetry by positioning the transparent material section at the edge of the card body rather than centering it or framing it symmetrically. This asymmetric placement creates a unique visual and tactile characteristic that is difficult to replicate, thereby enhancing counterfeiting security while maintaining structural simplicity
Solution Approach 2:
The patent applies local quality by having different regions of the card body with different properties - specifically, a transparent material section at the edge contrasting with the opaque card base body. This local differentiation creates security features that are both visually distinctive and structurally integrated, improving counterfeiting protection without excessive complexity
2Reliability
If a transparent material section is added to the card edge, then counterfeiting security is enhanced, but manufacturing complexity increases
Solution Approach 1:
The patent merges the transparent security feature with the card edge structure itself, rather than adding it as a separate component. The transparent material section is integrated into the card body formation process, allowing simultaneous creation of the card edge and security feature, thereby enhancing security while maintaining manufacturing simplicity
Solution Approach 2:
The patent applies preliminary action by incorporating the transparent material section into the card body during the initial formation process rather than adding it as a subsequent step. This preliminary integration ensures the security feature is built-in from the start, simplifying manufacturing by eliminating separate assembly steps
3Reliability
If the transparent material section forms part of the card edge, then visual and tactile security features are created, but material bonding requirements increase
Solution Approach 1:
The patent uses thin film materials for the transparent section, which can be flexibly bonded to the card base body. This approach allows for strong bonding while maintaining the flexibility and transparency needed for security features, creating unique visual and tactile characteristics without excessive bonding complexity
