Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machine-readable magnetic areas are provided in conventional security elements, then automatic verification is enabled, but detection becomes problematic when sensors encounter non-magnetic gaps between magnetic areas
Solution Approach 1:
The magnetic layer is segmented into multiple frame-shaped magnetic elements arranged in sequences, where each frame contains magnetic areas in its arms. This segmentation allows the magnetic information to be distributed across multiple discrete locations rather than requiring continuous magnetic coverage, enabling reliable detection even when sensors encounter gaps between frames or within frame structures.
Solution Approach 2:
The magnetic frames are arranged in multiple sequences that extend in directions transverse to the longitudinal direction of the security element. This multi-dimensional arrangement ensures that magnetic information is available across different spatial dimensions, allowing sensors to detect magnetic areas regardless of the specific transport direction or sensor position.
2Reliability
If magnetic material is used for machine-readable areas, then automatic verification is enabled, but transparency of negative writing areas is impaired
Solution Approach 1:
The magnetic layer is divided into frame-shaped elements with distinct arms and inner areas. The arms contain the magnetic material necessary for machine reading, while the inner areas remain free of magnetic material to preserve transparency for negative writing features. This segmentation allows magnetic and transparent regions to coexist within the same security element structure.
Solution Approach 2:
Different regions of the magnetic layer have different properties: the arms of the frames contain magnetic material for machine reading, while the inner areas are non-magnetic to maintain transparency. This local differentiation of material properties allows the security element to simultaneously achieve both magnetic detectability and optical transparency where required.
3Reliability
If space is allocated for magnetic areas, then machine reading is enabled, but design freedom for visual elements is restricted due to limited space
Solution Approach 1:
The magnetic information is segmented into multiple frame-shaped elements distributed across the security element. Each frame contains magnetic areas in its arms but leaves the inner area free for additional design elements. This segmentation distributes the magnetic functionality across multiple locations, freeing up continuous spaces for visual design elements and providing greater design freedom.
Solution Approach 2:
Magnetic frames are arranged in multiple sequences extending in transverse directions, distributing magnetic information across different spatial dimensions. This multi-dimensional distribution of magnetic elements liberates the longitudinal direction and other areas for visual design elements, enhancing design freedom while maintaining machine reading capability.
