Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the horizontal distance between lamps is increased to reduce light density, then light intensity on individual plants is reduced, but light uniformity on the light receiving surface is also reduced
Solution Approach 1:
The patent divides the light distribution function by using multiple reflectors positioned at different locations and angles. Each reflector segment directs light to specific zones, creating a segmented approach to light distribution that maintains both intensity and uniformity across the planting surface.
Solution Approach 2:
Different reflectors are positioned to provide localized light distribution optimization. The reflectors create zone-specific light patterns that address the unique lighting needs of different areas of the planting surface, ensuring uniformity while maintaining adequate intensity.
2Ease of manufacture
If lamps are fixed in a standard distribution above working aisles, then installation is simple, but light sources are wasted due to fixed distribution not adapting to plant needs
Solution Approach 1:
The patent introduces adjustable reflectors that can be positioned and angled to direct light dynamically toward plant canopies. This dynamic adjustment capability allows the lighting system to adapt to different plant growth stages and spatial requirements, maximizing light utilization efficiency while maintaining installation simplicity through modular design.
Solution Approach 2:
The reflector system ensures continuous and efficient light delivery to plants by capturing and redirecting light that would otherwise be lost. The multi-reflector configuration maintains continuous useful light action across the entire planting area, reducing energy waste while preserving the fixed installation advantage.
3Volume of moving object
If panel lamps are disposed on the top of multi-layer planting, then space utilization is improved, but light intensity cannot be reduced by adjusting height and edge plants receive insufficient light
Solution Approach 1:
The patent employs asymmetric reflector positioning and angling to address the asymmetric lighting problem at edge locations. Reflectors are strategically positioned to provide enhanced light distribution to edge plants that would otherwise receive insufficient light, creating an asymmetric compensation pattern that balances overall illumination across the planting area.
Solution Approach 2:
The patent adds angular dimensionality to light distribution through tilted and angled reflectors. By introducing angular variations in light reflection paths, the system achieves three-dimensional light distribution that compensates for the fixed horizontal position of panel lamps, ensuring adequate light intensity reaches edge plants without requiring height adjustment.
