Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If iris authentication is performed in outdoor environments with varying illumination conditions, then the system can be used in more environments, but the image capture quality deteriorates leading to reduced authentication accuracy
Solution Approach 1:
The patent applies dynamics by making the display unit's luminance adjustable and controllable. The display control unit dynamically adjusts the luminance of the authentication UI based on the captured image quality and environmental conditions, allowing the system to adapt to varying outdoor illumination conditions while maintaining optimal pupil diameter for authentication accuracy
Solution Approach 2:
The patent changes the luminance parameter of the display unit to control pupil diameter. By adjusting the display luminance, the system optimizes the pupil size in captured images, ensuring that the iris pattern is clearly visible regardless of external lighting conditions, thus maintaining authentication accuracy across different environments
2Measurement precision
If the pupil diameter is controlled by adjusting display luminance, then the authentication accuracy improves, but the device complexity increases
Solution Approach 1:
The system performs self-service by automatically analyzing the quality of captured iris images and autonomously adjusting the display luminance to optimize pupil diameter. The display control unit evaluates image quality metrics and independently controls the display unit without requiring manual intervention, simplifying the user interface while maintaining authentication accuracy
Solution Approach 2:
The patent implements feedback by using the quality assessment of captured images to adjust display luminance. The display control unit receives feedback from image quality analysis and dynamically modifies the display output to achieve optimal pupil diameter, creating a closed-loop control system that improves authentication accuracy without adding complex manual controls
