Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If two-dimensional image analysis is used for authentication, then the device complexity is reduced, but the measurement precision of three-dimensional security features deteriorates
Solution Approach 1:
The patent transitions from two-dimensional image analysis to three-dimensional detection by introducing height detectors that measure the vertical dimension of security features. The height detector captures the z-axis information of embossed marks and layer structures, enabling accurate verification of three-dimensional characteristics that cannot be detected by planar imaging alone.
Solution Approach 2:
The authentication system is divided into multiple specialized detectors: full mark detectors for two-dimensional pattern recognition, height detectors for vertical dimension measurement, and embossed mark detectors for surface topology analysis. Each detector segment handles specific aspects of security feature verification, improving overall measurement precision while maintaining manageable system complexity through modular design.
2Measurement precision
If multiple detectors are used to capture three-dimensional security features, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
Multiple detectors are integrated into a single authentication device that processes various security features simultaneously. The full mark detector, height detector, and embossed mark detector are combined in one system, allowing comprehensive verification of security features through coordinated operation rather than requiring separate devices for each detection type.
Solution Approach 2:
The authentication device is designed as a multi-functional system capable of detecting different types of security features using various detection methods. The device can authenticate both two-dimensional printed marks and three-dimensional embossed features, as well as verify layer structures, making it a universal authentication solution that handles diverse security feature types within a single platform.
3Reliability
If height detection is implemented to verify card layers, then the reliability of authentication improves, but the manufacturing precision requirements increase
Solution Approach 1:
The height detector provides feedback information about the actual vertical dimensions of security features and layer structures. This measured data is compared against expected values to verify authenticity, creating a feedback mechanism that enhances authentication reliability by confirming that manufactured features match their specified dimensional parameters.
