Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If LED lighting elements are used to replace traditional bulbs, then power consumption is reduced, but lighting angle optimization fails causing increased glare and inadequate illuminance
Solution Approach 1:
The patent applies local quality by positioning LED lighting elements at specific angles (e.g., 30 degrees from vertical) and using zone-based control where different portions of the LED array can be independently controlled. This allows optimization of lighting in specific areas (sidewalks, streets) while reducing glare in others, thereby improving illumination intensity in targeted zones while maintaining energy efficiency.
Solution Approach 2:
The patent implements dynamics through remotely controllable LED lighting systems that can adjust lighting angles, intensity, and distribution patterns after installation. The control system allows dynamic modification of lighting parameters to optimize illuminance and reduce glare based on time of day, weather conditions, or specific operational requirements, thereby resolving the contradiction between fixed LED positioning and optimal lighting performance.
2Ease of manufacture
If fixed LED lighting designs are used, then manufacturing is simplified, but control over light distribution patterns and light levels is limited
Solution Approach 1:
The patent applies segmentation by dividing the LED lighting system into multiple independently controllable zones or groups. Each zone can be controlled separately to create different light distribution patterns, adjust intensity levels, or target specific areas. This segmentation maintains the simplicity of fixed LED manufacturing while enabling versatile post-installation control and customization of lighting patterns.
Solution Approach 2:
The patent implements universality by designing LED lighting fixtures that can perform multiple functions through a single integrated system. The same fixed LED structure can be controlled to provide various lighting patterns, adjust to different operational modes (e.g., full illumination, partial illumination, decorative modes), and adapt to different environmental conditions, thereby achieving versatility without complicating the manufacturing process.
3Area of stationary object
If LED lighting directs light horizontally, then area coverage is maximized, but glare increases and backlighting onto homes occurs
Solution Approach 1:
The patent applies local quality by controlling different zones of the LED array to direct light in different directions. Some zones may direct light horizontally for area coverage, while other zones direct light at downward angles to reduce glare and prevent backlighting onto homes. This zone-based differential control allows simultaneous achievement of area coverage and harmful factor reduction.
Solution Approach 2:
The patent implements feedback through control systems that can adjust LED lighting based on environmental conditions, time of day, or detected glare levels. The system receives feedback about lighting conditions and automatically adjusts the distribution pattern and intensity to minimize glare and backlighting while maintaining adequate area coverage, thereby dynamically resolving the contradiction between coverage and harmful effects.
