Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional street lighting systems are used to provide illumination, then lighting coverage is achieved, but luminous pollution and high energy consumption occur
Solution Approach 1:
The patent applies local quality by using asymmetric optics with specifically designed refractive surfaces that direct light preferentially toward the road surface rather than uniformly in all directions. The asymmetric lens geometry creates localized light concentration on the road while minimizing upward light emission that causes luminous pollution.
Solution Approach 2:
The patent changes the optical parameters by using asymmetric lens designs with specific refractive indices and surface curvatures. The asymmetric optics modify the light distribution pattern from conventional symmetric patterns to directional patterns that optimize road illumination while reducing skyward light emission.
2Illumination intensity
If custom lighting systems are designed for each road typology to optimize luminous distribution, then lighting optimization is achieved, but production and design costs increase
Solution Approach 1:
The patent applies universality by designing a standardized lighting system with asymmetric optics that can be universally applied to different road typologies. The asymmetric lens design inherently provides optimized light distribution for various road configurations without requiring custom design for each application, making the system multi-functional across different street lighting scenarios.
Solution Approach 2:
The patent enables dynamic adaptability by allowing the asymmetric optics to be configured in different orientations and arrangements to suit various road typologies. The system can be dynamically adapted to different lighting requirements through geometric arrangement of the asymmetric lenses rather than through custom design, reducing production costs while maintaining optimization.
3Adaptability or versatility
If entire illuminating bodies are replaced to adapt to road modifications, then correct illumination is achieved, but system complexity and replacement costs increase
Solution Approach 1:
The patent applies segmentation by separating the asymmetric optics from the illuminating body housing. This allows the optics to be independently replaced or reconfigured without replacing the entire illuminating body. The modular design enables adaptive response to road modifications by simply changing the optic components rather than the complete system.
4Illumination intensity
If multiple components are used in lighting systems to achieve desired luminous distribution, then lighting performance is improved, but production costs and assembly complexity increase
Solution Approach 1:
The patent applies merging by integrating the asymmetric optics directly into the illuminating body housing as a unified component. The asymmetric lens is molded or attached as an integral part of the housing structure, eliminating the need for separate adjustment mechanisms, mounting brackets, and alignment devices. This reduces the total component count while maintaining optimized luminous distribution.
