Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If medium-high color temperature light is emitted by conventional road lamp, then luminous efficiency is improved, but penetration rate deteriorates in rainy days
Solution Approach 1:
The patent segments the light-emitting system into multiple independent light-emitting elements with different color temperatures (e.g., first light-emitting elements with medium-high color temperature and second light-emitting elements with low color temperature). Each element can be controlled separately, allowing the system to select or combine different color temperature lights based on environmental conditions such as weather, thereby resolving the contradiction between luminous efficiency and penetration rate.
Solution Approach 2:
The patent implements dynamic control of light emission by using a controller to adjust the emission state of different light-emitting elements based on real-time environmental conditions. The system can dynamically switch between medium-high color temperature light (for clear weather with high luminous efficiency) and low color temperature light (for rainy weather with better penetration), or combine them in various ratios, making the lighting system adaptive to changing conditions.
2Object-affected harmful factors
If low color temperature light is emitted by conventional road lamp, then penetration rate in rainy days is improved, but luminous efficiency deteriorates
Solution Approach 1:
The patent divides the lighting system into multiple light-emitting elements with different color temperature characteristics. Second light-emitting elements emit low color temperature light with better penetration rate, while first light-emitting elements emit medium-high color temperature light with higher luminous efficiency. The controller can selectively activate second light-emitting elements during rainy conditions to improve penetration while maintaining energy efficiency.
Solution Approach 2:
The system dynamically adjusts the emission characteristics by controlling different light-emitting elements based on environmental conditions. During rainy days, the controller increases the proportion of low color temperature light emission to improve penetration rate, while during clear weather, it switches to medium-high color temperature light for optimal luminous efficiency, thus dynamically optimizing the balance between penetration and energy consumption.
3Ease of operation
If conventional road lamp emits fixed color temperature light, then control simplicity is maintained, but adaptability to environmental changes deteriorates
Solution Approach 1:
The patent segments the light-emitting system into multiple independently controllable light-emitting elements with different color temperature characteristics. This segmentation allows the controller to selectively activate specific elements based on environmental conditions without requiring complex mechanical adjustments, maintaining control simplicity while significantly improving adaptability to different weather conditions.
Solution Approach 2:
The patent implements dynamic control where the controller automatically adjusts the emission state of different light-emitting elements based on environmental conditions such as weather, time, or road conditions. This dynamic adaptation allows the system to respond to environmental changes without manual intervention, maintaining ease of operation while achieving high versatility and adaptability.
