Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an infrared camera is used to acquire biometric data, then authentication security is improved, but image quality and color accuracy deteriorate
Solution Approach 1:
The patent combines an infrared camera and a visible light camera into a single electronic device, allowing the system to use both cameras simultaneously or selectively. The infrared camera provides secure biometric authentication while the visible light camera captures color images for display, merging the security benefits of infrared with the visual quality of visible light imaging.
Solution Approach 2:
The electronic device is designed with multi-functional capability by incorporating both infrared and visible light cameras. The system can perform biometric authentication using infrared data while also providing visual feedback through color images from the visible light camera, making the device universally applicable for both security and user interface functions.
2Reliability
If an infrared camera is used to acquire biometric data, then authentication capability is improved, but color accuracy and visual quality deteriorate
Solution Approach 1:
The system merges the functional capabilities of two different camera types. The infrared camera captures biometric data for authentication while the visible light camera captures color information for display, combining the strengths of both imaging modalities to avoid information loss.
Solution Approach 2:
The visible light camera acts as an intermediary that captures color images for display purposes. When the infrared camera acquires biometric data, the visible light camera simultaneously captures the corresponding color image, which serves as a visual intermediary between the user and the authentication process, preventing loss of color information in the displayed feedback.
3Manufacturing precision
If a visible light camera is used to provide images for display, then image quality is improved, but operation is restricted in certain contexts
Solution Approach 1:
The system dynamically selects which camera to use for display based on contextual conditions. The processor determines whether to use the visible light camera or infrared camera for providing images to the display, allowing flexible adaptation to different operational contexts such as low light conditions, privacy requirements, or authentication stages.
Solution Approach 2:
The system changes operational parameters by switching between different camera modes and image processing settings based on context. This includes adjusting which camera is active, modifying image processing algorithms, and changing display parameters to optimize performance for different situations while maintaining image quality.
