Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If face authentication is performed using ambient light conditions, then the device complexity is reduced, but the image quality and authentication accuracy deteriorate due to brightness variations
Solution Approach 1:
The patent applies preliminary action by installing dedicated lighting devices (first light and second light) that illuminate the user's face before the camera captures the image. This ensures that the face is properly lit regardless of ambient light conditions, thereby guaranteeing high-quality images for authentication without increasing overall system complexity
Solution Approach 2:
The patent uses lighting devices as intermediaries between the ambient environment and the camera sensor. These lights mediate the illumination conditions, converting variable ambient light into consistent, controlled lighting that ensures high image quality for authentication purposes
2Measurement precision
If high-quality images are acquired for accurate authentication, then the authentication accuracy is improved, but the device complexity increases due to additional lighting control components
Solution Approach 1:
The patent applies universality by designing a lighting system that serves multiple functions: the first light provides general illumination, the second light provides supplementary illumination, and together they ensure consistent lighting across different ambient conditions. This multi-functional approach achieves high authentication accuracy without requiring multiple separate lighting systems
Solution Approach 2:
The patent applies parameter changes by adjusting the luminance of the first and second lights based on detected ambient light levels and user position. This dynamic parameter adjustment ensures optimal image quality for authentication while avoiding the need for overly complex fixed high-intensity lighting systems
3Ease of operation
If ambient light conditions are used for face capture, then the ease of operation is improved, but the reliability of authentication deteriorates due to brightness variations at different times of day
Solution Approach 1:
The system performs preliminary action by automatically detecting ambient light conditions and activating the appropriate lighting devices before image capture. This ensures that users can simply stand in front of the device without manually adjusting lighting, maintaining ease of operation while ensuring authentication reliability through controlled illumination
Solution Approach 2:
The patent applies feedback by using light detection devices to monitor ambient lighting conditions and user position, then automatically adjusting the luminance of the first and second lights accordingly. This closed-loop feedback system maintains authentication reliability while requiring minimal user intervention, preserving ease of operation
