Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If higher power equipment is used to generate greater amounts of light, then the desired lighting requirements in the target area are met, but energy consumption increases
Solution Approach 1:
The reflector assembly is divided into multiple modular reflector units, each capable of being independently oriented to direct light in specific directions. This segmentation allows precise control over light distribution patterns, ensuring that light is directed only where needed to meet illumination requirements while minimizing energy waste in unwanted directions.
Solution Approach 2:
Different portions of the reflector assembly are oriented differently to create distinct light distribution patterns in different areas. This local differentiation ensures that each region receives appropriate lighting intensity based on its specific requirements, optimizing the balance between illumination needs and energy consumption in each zone.
2Illumination intensity
If more light is generated to meet lighting requirements, then the target area is adequately illuminated, but uncontrolled light is wasted in areas around the target area
Solution Approach 1:
The reflector assembly is divided into multiple modular reflector units, each capable of being independently oriented to direct light in specific directions. This segmentation allows precise control over light distribution patterns, ensuring that light is directed only where needed to meet illumination requirements while minimizing energy waste in unwanted directions.
Solution Approach 2:
Different portions of the reflector assembly are oriented differently to create distinct light distribution patterns in different areas. This local differentiation ensures that each region receives appropriate lighting intensity based on its specific requirements, optimizing the balance between illumination needs and energy consumption in each zone.
3Illumination intensity
If multiple light sources are used to meet lighting requirements, then the desired illumination is achieved, but the complexity of the lighting system increases
Solution Approach 1:
Multiple identical reflector modules are used in the assembly, where each module can be oriented to perform different functions by directing light in different directions. This universality reduces design complexity compared to using different types of reflectors for different functions, while still meeting diverse lighting requirements through systematic arrangement and orientation of the same modular units.
