Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a fill light is used to increase brightness in low-light environments, then image clarity is improved, but eye irritation increases and local shadows may worsen if brightness is not properly adjusted
Solution Approach 1:
The patent implements dynamic brightness adjustment by continuously detecting ambient light conditions through a light sensing unit and automatically adjusting the fill light output accordingly. This dynamic adaptation ensures optimal brightness without causing eye irritation, resolving the contradiction between improving image clarity and preventing harmful effects.
Solution Approach 2:
The system employs feedback control by using the light sensing unit to monitor ambient light levels and feed this information back to the control unit, which then adjusts the fill light intensity. This closed-loop feedback mechanism prevents both insufficient brightness and excessive brightness that causes eye irritation.
2Illumination intensity
If brightness is increased to compensate for low ambient light, then image clarity improves, but local shadow areas increase if brightness is too weak
Solution Approach 1:
The system dynamically adjusts fill light intensity based on real-time ambient light detection, ensuring sufficient brightness to eliminate local shadows while maintaining image clarity. This dynamic adjustment prevents the reliability issue of insufficient brightness compensation.
3Reliability
If ambient light detection and dynamic adjustment are implemented, then image quality and comfort are improved, but device complexity increases
Solution Approach 1:
The light sensing unit serves multiple functions: detecting ambient light intensity, determining color temperature, and providing data for both brightness and color adjustment. This multi-functionality reduces the need for separate components, thereby limiting the increase in device complexity while improving image quality and viewing comfort.
