Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional elevated streetlight poles are used to provide illumination, then light intensity can be increased, but driver safety is compromised due to glare and the poles themselves become collision hazards
Solution Approach 1:
The lighting system transitions from vertical elevation (elevated poles) to horizontal ground-level installation. The lighting device is mounted on the roadway surface itself, illuminating the road from below rather than from above, thereby eliminating glare to drivers while maintaining illumination intensity.
Solution Approach 2:
The harmful element (elevated pole structure) is removed from the system. Only the lighting function remains, integrated directly into the roadway surface, eliminating the collision hazard of elevated poles while preserving the illumination function.
2Object-affected harmful factors
If regulated light intensity limits are applied to avoid dazzling drivers, then driver safety is improved, but road illumination effectiveness deteriorates
Solution Approach 1:
By changing the illumination direction from top-down (which causes glare) to bottom-up (which illuminates the road surface without dazzling drivers), the system achieves both effective road illumination and driver safety simultaneously.
3Area of stationary object
If traditional elevated lighting systems are installed, then illumination coverage can be achieved, but cost efficiency deteriorates due to pole purchase, installation, maintenance, and removal
Solution Approach 1:
The expensive pole structure is completely removed from the system. The lighting function is achieved through ground-level modules that require no elevated support structure, significantly reducing material costs, installation complexity, and long-term maintenance requirements.
Solution Approach 2:
The system uses affordable, modular ground-level lighting units that can be easily replaced if needed, eliminating the need for expensive, permanent elevated pole infrastructure.
4Adaptability or versatility
If obstructions such as trees and signage are present on roadways, then environmental and aesthetic requirements are met, but light uniformity deteriorates due to blocked light paths
Solution Approach 1:
By installing lighting at ground level rather than elevated positions, the system illuminates the road surface directly without being blocked by trees, signage, or other roadside obstructions, maintaining uniform light distribution regardless of environmental features.
