Information Cards TRIZ Cases
- Caustic Surface Design for Visual Authentication
A piecewise light-redirecting surface design method computes optimal weights to form accurate caustic patterns.
- Graphene Security Thread for Banknotes Using Liquid Crystal Color Shift
Replacing metallic coatings with graphene eliminates corrosion while maintaining electroconductivity and enabling RFID integration.
- Security Paper Weakness Lines Destroy Features on Splitting
Lines of weakness in carrier substrates destroy embedded security features when split, preventing reuse of sub-layers for counterfeiting.
- Security Product Decentralized Individualization with Overlapping Prints
Printing overlapping security features on outer layers resolves the trade-off between manipulation resistance and multicolored reproduction capability.
- Microoptical System Zero-Order 3D Image Diffraction
A microoptical system forms a 3D image in the zero diffraction order using multilevel kinoforms and electron beam lithography.
- Multilayer Identification Document Data Page Security Structure
Integrating a transparent layer into opaque openings creates visible security elements that resist tampering while simplifying manufacturing steps.
- One-Component Adhesive for Security Document Bonding
A one-component adhesive cures under actinic radiation to bond security elements securely.
- Digital Emergency Card System for Building Rescue Data
A digital emergency card system stores and transmits building data to first responders.
