Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate layers and components are used to create security features, then the security element can provide multiple security functions, but the device complexity and manufacturing complexity increase
Solution Approach 1:
The patent combines microstructures and diffractive structures into a single integrated layer, eliminating the need for separate layers and reducing structural complexity while maintaining multiple security functions. The microstructures and diffractive structures are formed in the same transparent plastic layer, creating a unified security element that is both simpler and more reliable.
Solution Approach 2:
The single transparent plastic layer serves multiple security functions simultaneously by incorporating both microstructures (for magnification and image formation) and diffractive structures (for color effects and verification). This multi-functional approach eliminates the need for multiple separate components while enhancing security.
2Reliability
If multiple separate embossing tools and steps are used to form different security structures, then various security features can be created, but the manufacturing complexity and time increase
Solution Approach 1:
The patent merges the formation of microstructures and diffractive structures into a single embossing step using one embossing tool. The embossing tool contains both microstructure-forming elements and diffractive structure-forming elements that simultaneously create both security features during one manufacturing process, significantly simplifying production.
Solution Approach 2:
The embossing tool is pre-configured with all necessary elements to form both microstructures and diffractive structures in a single operation. This preliminary preparation of the tool allows for efficient one-step formation of multiple security features without requiring sequential processing steps.
3Reliability
If additional layers and components are added to enhance security, then the security element provides more verification features, but the manufacturing precision requirements and contamination risk increase
Solution Approach 1:
By combining microstructures and diffractive structures in a single layer formed through one embossing process, the patent eliminates alignment issues between separate layers. The integrated formation ensures precise spatial relationships between different security features without requiring complex precision alignment procedures.
