Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple printing inks are used to create magnetic regions, then security against forgery is improved, but production complexity and fluctuations increase
Solution Approach 1:
The patent combines multiple magnetic materials with different coercivities into a single printing ink formulation. This allows the security element to maintain high anti-forgery reliability through complex magnetic region differentiation while simplifying production by using only one printing ink, thereby eliminating production fluctuations and complexities associated with multiple inks.
Solution Approach 2:
The patent changes the magnetic parameters (coercivity) by incorporating multiple magnetic materials with different coercivity values into a single ink. This enables the creation of distinct magnetic regions with different signal strengths that are difficult to forge, while maintaining production simplicity through single-ink application.
2Reliability
If multiple printing inks are used to create magnetic regions, then unique magnetic coding is achieved, but production fluctuations and costs increase
Solution Approach 1:
The patent merges multiple magnetic materials into a single printing ink, enabling unique magnetic coding through the differential coercivity of the materials while simplifying manufacturing processes. This eliminates the need for precise registration and timing required when applying multiple inks, significantly improving production ease and reducing costs.
3Reliability
If magnetic materials with different coercivities are used in a mixture, then resistance to forgery is increased, but signal strength consistency may be affected
Solution Approach 1:
The patent utilizes the different coercivity parameters of multiple magnetic materials to create forgery-resistant security features. By carefully selecting and formulating the mixture ratio of materials with different coercivities, the patent ensures that each magnetic region produces a consistent and distinguishable signal strength, thereby maintaining manufacturing precision while enhancing anti-forgery capabilities.
4Ease of manufacture
If a single printing ink with defined mixing ratio is used, then production simplicity is improved, but security against forgery may be reduced
Solution Approach 1:
The patent creates a composite printing ink that contains multiple magnetic materials with different coercivities in defined mixing ratios. This composite ink maintains production simplicity through single-ink application while providing enhanced security against forgery through the complex magnetic signatures that result from the different coercivity values of the constituent materials.
