Multi-Axis Security Element with Variable Movement Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current security elements for securities and security papers lack sufficient protection against forgery, as they only provide a single movement image when tilted, which can be easily replicated, thereby failing to enhance security effectively.
Innovation Solution
Incorporating a second structural region with distinct movement images when tilted about a different axis, allowing for varied movement impressions or no impressions, with the first and second axes forming an apex angle of 10° to 90°, and utilizing micromirrors, diffractive structures, and reflective layers for enhanced security features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single structural area with first structures is used to generate a movement image when tilted, then the security element provides basic anti-counterfeiting protection, but the protection is insufficient and can be easily replicated
Solution Approach 1:
The security element is divided into multiple structural areas (first structural area with first structures, second structural area with second structures) that can be tilted about different axes independently. Each structural area generates distinct movement images, increasing the complexity of replication while maintaining manageable individual components
Solution Approach 2:
The patent introduces multiple tilting axes (first axis, second axis) that enclose an apex angle, adding dimensional complexity to the movement image generation. This multi-axis approach creates movement impressions that are difficult to replicate as they require precise three-dimensional orientation control
2Reliability
If multiple structural areas with different movement images are added to increase security protection, then the anti-counterfeiting capability is enhanced, but the device complexity increases
Solution Approach 1:
Multiple structural areas serve the universal function of generating movement images for security verification, but each area is configured with different structures and tilting axes to provide varied movement impressions. This multi-functionality approach enhances security while maintaining a unified security element design
