Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If software solutions are used to reduce high-energy blue light, then harmful light emission is reduced, but color temperature and system color accuracy are significantly impacted
Solution Approach 1:
The patent segments the light spectrum management by using a physical filter that specifically targets only the harmful blue light wavelengths (415-455 nm) while allowing other wavelengths to pass through. This is combined with software that selectively adjusts only the blue light channel, rather than applying blanket adjustments across the entire visible spectrum, thereby preserving color accuracy while reducing harmful emissions.
Solution Approach 2:
The physical filter is designed with localized optical properties that selectively absorb or block only the harmful blue light band (415-455 nm) while maintaining transparency to other wavelengths. This localized filtering approach, combined with software that applies color correction only to the blue channel, ensures that harmful light is reduced without degrading overall system color accuracy.
2Object-affected harmful factors
If physical filters are used to reduce high-energy blue light, then harmful light emission is reduced, but coverage across the blue light spectrum is limited and system color is impacted
Solution Approach 1:
The patent merges a physical filter with software-based light management to create a hybrid system. The physical filter provides baseline reduction of harmful blue light wavelengths, while the software layer adds adaptability by dynamically adjusting blue light emission based on usage patterns, ambient light conditions, and user preferences. This combination achieves both spectrum coverage and adaptability that neither solution could achieve alone.
Solution Approach 2:
The system transitions from a static physical filter to a dynamic hybrid solution where software continuously monitors and adjusts blue light emission levels based on real-time conditions such as time of day, ambient lighting, and cumulative exposure metrics. This dynamic adjustment capability enhances spectrum coverage adaptability while the physical filter maintains its role in blocking harmful wavelengths.
3Object-affected harmful factors
If software filtration of high-energy visible light is implemented, then harmful light band management is attempted, but narrow band management capability is limited and manual adjustment is required
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors cumulative blue light exposure, time of day, and ambient lighting conditions. Based on this feedback, the software automatically adjusts the blue light filter strength and spectral management parameters without requiring manual user intervention. The system can also provide feedback to the user about exposure levels and recommended settings.
Solution Approach 2:
The hybrid system performs self-adjustment by automatically managing blue light filtration based on pre-programmed algorithms that consider cumulative exposure metrics, circadian rhythm considerations, and ambient conditions. The physical filter provides automatic passive filtration, while the software layer autonomously adjusts digital blue light emission, eliminating the need for manual user configuration and adjustment.
4Object-affected harmful factors
If existing light management solutions are used, then some blue light reduction is achieved, but cumulative exposure tracking and intelligent adjustment are not provided
Solution Approach 1:
The system implements comprehensive feedback loops that track cumulative blue light exposure over time and use this information to dynamically adjust filtration strength. The software monitors total exposure duration, intensity, and patterns, then automatically modifies blue light management parameters to prevent excessive cumulative exposure. This feedback mechanism enables intelligent adaptation to individual usage patterns.
Solution Approach 2:
The system performs preliminary assessment of usage patterns and environmental conditions to proactively adjust blue light filtration before harmful cumulative exposure occurs. By monitoring time of day, expected usage duration, and ambient lighting conditions in advance, the system can pre-adjust filter settings to prevent excessive exposure while maintaining visual comfort and color accuracy throughout the usage session.
