Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple images are captured and processed to verify security features, then authentication accuracy is improved, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary actions by capturing the document image and detecting security features before the actual authentication decision is made. The electromagnetic signal is emitted to illuminate security features in advance, and the system prepares verification criteria beforehand, reducing the time needed for final authentication.
Solution Approach 2:
The system extracts only the essential security features from the document using electromagnetic signals, rather than processing entire multiple images. By isolating and analyzing specific security features (holograms, watermarks, etc.) that are illuminated by the electromagnetic signal, the system reduces processing complexity while maintaining authentication accuracy.
2Measurement precision
If multiple images are captured and processed to verify security features, then authentication accuracy is improved, but device complexity increases
Solution Approach 1:
The system uses a single device (smartphone or portable electronic device) that performs multiple functions: emitting electromagnetic signals to illuminate security features, capturing images of the document, processing the captured images, and making authentication decisions. This multi-functional approach reduces the need for multiple separate devices and complex system architecture.
Solution Approach 2:
The system combines the electromagnetic signal emission, image capture, image processing, and authentication decision-making into a single integrated system. By merging these functions that were previously distributed across multiple devices or systems, the overall system complexity is reduced while maintaining the ability to verify security features accurately.
3Measurement precision
If electromagnetic signal parameters are adjusted based on document location, then security feature detectability is improved, but measurement complexity increases
Solution Approach 1:
The system uses feedback from document location detection to automatically adjust electromagnetic signal parameters. The device detects the document's position and orientation, then uses this information to adjust the intensity, angle, or other parameters of the electromagnetic signal to optimize illumination of security features, reducing the need for manual measurement and adjustment.
Solution Approach 2:
The system performs self-adjustment of electromagnetic signal parameters based on automatically detected document characteristics. Rather than requiring manual measurement and setup, the system autonomously adapts the signal parameters to the document's position and orientation, simplifying the measurement process while improving security feature detectability.
