Information Cards TRIZ Cases
- Protective Layer for Laser-Sensitive Security Documents
A protective layer separates laser-sensitive materials from polycarbonate substrates to maintain high image quality in security documents.
- Embedded Paper Strip in Polymer Film for Banknote Security
A multi-layer substrate embeds a watermark-bearing paper strip between extruded film webs to create a durable value document.
- Optically Variable Security Device Using Color-Shifting Layers
A security device uses layered color-shifting materials and a light control layer to modify reflected light angles.
- Polymer Film Security Element via Standing Light Wave Interference
Standing light waves generate microfibrils in polymer films, replacing expensive photoresists to simplify production of colorful security elements.
- Biometric ID Lens Arrangement for Forgery Resistance
A lens arrangement creates a three-dimensional effect from base and derivative images, increasing forgery resistance by emphasizing geometric relationships.
- Value Document Perforation Film Security Element
A perforated value document substrate integrates a film security element with transparent and non-transparent regions to generate distinct visual motifs.
- Card Security Element with Oblique Cylindrical Lenses
Oblique cylindrical viewing grids reconstruct high-resolution target images through moiré magnification.
- Multi-page Security Document Laser Personalization
Laser-alterable ink layers on document edges form a two-dimensional pattern across adjacent pages to detect page swapping and prevent counterfeiting.
- Laser-Processed Security Feature With Colored Hole Borders
Laser radiation with intensity distribution creates perforated holes and modifies marking substances to form colored rims on substrates.
- Security Element Ink Layering for Infrared Transparency
Segmented ink layers resolve the contradiction between visible opacity and infrared transparency, enabling hidden security features to be detected.
- Dichroic Dye Liquid Crystal Foil for Dual-Side Security
Embossed liquid crystal foil with dichroic dyes produces distinct dual-side images.
- Security Devices with Polarisation-Dependent Zero-Order Outputs
Dual embossed reflective metal diffraction gratings generate polarisation-dependent zero-order colour effects to strengthen security against copying.
- Optically Variable Security Element Encoding Multiple Motifs
Integrating diffraction gratings between reflective structures increases information density without requiring large angular separation ranges.
- Dual-Sided Security Element Using Reflective Micro-Imaging
A security element uses reflective micro-imaging elements on one side and microlenses on the other to create enlarged images from both surfaces.
- Security Document Variable Color Inversion Optical Patterns
Segmented optical patterns permute colors during observation mode switching, resolving authentication ambiguity while complicating reproduction.
- Groove-Shaped Security Elements for Banknotes
Groove-shaped structural elements scatter parallel light to generate three-dimensional movement effects without complex color coatings.
