Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security elements are vulnerable to counterfeiting and lack customization and variety in visual effects, making them susceptible to forgery.
Innovation Solution
Incorporating a micro-image arrangement with a colour-shifting layer on a relief structure, which is only discernible through a focusing layer, creating a viewing-angle-dependent colour impression and enhancing the security element's difficulty to forge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a micro-image arrangement is used in security elements, then protection against counterfeiting is enhanced, but the device complexity increases due to multiple layers and components
Solution Approach 1:
The patent combines multiple functional layers (micro-image arrangement, colour-shifting layer, focusing layer) into a single integrated security element structure. This merging approach maintains high counterfeit protection while reducing overall system complexity by consolidating components that work together synergistically within one element.
Solution Approach 2:
The security element incorporates multiple functions within a single structure: the micro-image arrangement provides base security, the colour-shifting layer adds dynamic visual verification, and the focusing layer enables magnification effects. This multi-functionality enhances counterfeit protection without requiring separate independent components.
2Adaptability or versatility
If a colour-shifting layer is added to the micro-image arrangement, then customization and visual variety are enhanced, but the manufacturing complexity increases
Solution Approach 1:
The colour-shifting layer utilizes changes in optical parameters (colour, transparency, magnification) based on viewing conditions such as angle and focal distance. This allows high customization and visual variety while maintaining relatively simple manufacturing processes, as the effects are achieved through material properties rather than complex structures.
3Reliability
If multiple layers are integrated to create viewing-angle-dependent effects, then protection against counterfeiting is enhanced, but the manufacturing precision requirements increase
Solution Approach 1:
The patent achieves high counterfeit protection through parameter changes in the colour-shifting layer (colour, transparency, magnification) that respond to viewing conditions. This approach enhances security reliability while avoiding the need for extremely precise manufacturing tolerances, as the effects are achieved through material optical properties rather than tight dimensional tolerances.
