Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional daylighting curtains are used, then the structure is simple and easy to manufacture, but the natural light cannot be evenly scattered into the room at different lighting stages
Solution Approach 1:
The daylighting curtain is divided into multiple thin light sheets arranged in a matrix, with each sheet containing lens arrays and sawtooth gratings. This segmentation allows different regions to handle different incident angles of sunlight throughout the day, achieving uniform light distribution while maintaining manageable structural complexity through modular repetition
Solution Approach 2:
Each thin light sheet combines two different optical elements: lens arrays on the outer surface and sawtooth gratings on the inner surface. This composite structure enables the curtain to effectively process natural light at various incident angles by leveraging the complementary optical properties of both elements
2Adaptability or versatility
If traditional daylighting curtains are used, then the manufacturing process is simple, but the device cannot adapt to natural light at different incident angles throughout the day
Solution Approach 1:
The daylighting curtain is designed with ten different thin light sheets, each optimized for specific incident angle ranges. As the sun moves across the sky and incident angles change throughout the day, different sheets become active, allowing the system to dynamically adapt to varying lighting conditions without requiring mechanical movement
Solution Approach 2:
During the manufacturing stage, ten different thin light sheets are pre-configured with specific lens and grating combinations tailored to different incident angles. This preliminary preparation ensures that when natural light enters at any angle during operation, the appropriate pre-designed sheet is already in position to handle it effectively
