Information Cards TRIZ Cases
- Distributed Mirror Surfaces for Angle-Dependent Image Visibility
A layered structure with distributed mirror surfaces controls image visibility through angle-dependent reflection.
- Optically Variable Security Element with Decoupled Kinematic and Chromatic Tilting
Diffractive grating patterns decouple chromatic tilting from kinematic motion, eliminating costly vacuum deposition processes.
- Reflective Microlens Optical Film for Thin 3D Imaging
An integral reflective microlens structure reduces film thickness while maintaining large aperture design space and environmental durability.
- Translucent Security Element in Identification Documents
Variable core thickness creates a translucent region that reveals forgery marks during backlight inspection without compromising front-side opacity.
- Luminescent Security Motif with Spectral Color Matching
A luminescent motif area uses spectral components to create a uniform hue under UV excitation.
- Transfer Film with Lacquer Grid for Security Elements
A transfer film uses a stable lacquer grid to anchor thin security element layers during separation from a temporary carrier.
- Lenticular Security Element with Radiation-Sensitive Motif
Radiation-sensitive motif layers enable precise registration with microlenses, reducing alignment costs while maintaining high security against forgery.
- Multilayer Security Document Color Laser Marking
Segmented layers filter laser wavelengths to prevent unwanted bleaching interference, enabling pure magenta and cyan colors.
- Security Element Moiré Magnification Design Freedom
Distributing motif portions across multiple lattice cells creates larger non-overlapping moiré elements, resolving thickness and design freedom constraints.
- Laser Perforation Device for Security Documents
Dual-matrix positioning and laser beams produce precise perforations in security documents, resolving precision versus complexity trade-offs.
- Thickness-Modulated Security Filaments for Flatness
Thickness modulation of security filaments compensates for window-paper differences, resolving stacking waviness in banknote processing.
