Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication patterns are used, then the authentication device is simple to manufacture, but the ability to distinguish between similar patterns is insufficient leading to false positives or negatives
Solution Approach 1:
The authentication pattern is divided into multiple discrete pattern-forming members, each comprising multiple pattern-defining elements. This segmentation allows for increased complexity and uniqueness in the overall pattern while maintaining manufacturability through modular construction. Each member can be independently formed and then assembled into the complete authentication pattern.
Solution Approach 2:
Different pattern-forming members and pattern-defining elements within members have contrasting optical or visual properties, creating local variations in appearance. This local quality differentiation enhances the distinguishability of the authentication pattern, allowing verification systems to detect genuine patterns more reliably while maintaining a manageable overall structure.
2Measurement precision
If woven patterns with contrasting threads are used, then pattern distinguishability is improved, but manufacturing precision requirements increase
Solution Approach 1:
The pattern-defining elements are formed by twisting threads in preliminary actions that create stable, reproducible structures. The twisting process establishes the pattern characteristics before final assembly, ensuring that the optical and visual properties are predetermined and can be verified against reference patterns without requiring extremely tight tolerances during final manufacturing.
Solution Approach 2:
The authentication pattern uses composite construction with multiple threads of contrasting optical or visual properties twisted together. This composite approach allows the pattern to incorporate multiple distinguishing features within each pattern-forming member, enhancing verification accuracy while the modular nature of the composite structure maintains manufacturing feasibility.
3Reliability
If multiple pattern defining elements are used in each woven element, then authenticity verification reliability is enhanced, but the device complexity increases
Solution Approach 1:
The complex authentication pattern is segmented into multiple pattern-forming members, with each member containing multiple pattern-defining elements. This hierarchical segmentation allows the system to achieve high reliability through the cumulative effect of multiple distinguishable features while keeping individual components manageable in size and complexity for manufacturing purposes.
Solution Approach 2:
The pattern complexity is managed by organizing multiple pattern-defining elements within a two-dimensional woven structure. The elements are arranged in specific spatial relationships (adjacent or abutting positions) that create a comprehensive authentication signature without requiring three-dimensional complexity, thus enhancing verification reliability while maintaining manufacturing feasibility.
