Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high intensity discharge lamps are used to illuminate wide areas, then illumination intensity is improved, but light distribution control deteriorates causing waste on rack tops and equipment surfaces
Solution Approach 1:
The lighting system is segmented into multiple independent LED modules, each capable of being individually controlled and directed. This segmentation allows precise targeting of light to specific areas needing illumination while avoiding unnecessary illumination of rack tops and equipment surfaces, thereby reducing light waste while maintaining required illumination intensity.
Solution Approach 2:
The patent implements local quality by providing different illumination characteristics to different spatial zones. LED modules are positioned and angled to deliver concentrated light to specific work areas, aisles, or product zones, while minimizing light spill to areas where illumination is not needed, thus reducing energy waste while maintaining high illumination intensity where required.
2Area of stationary object
If high intensity discharge lamps are installed in a fixed grid pattern, then coverage area is improved, but adaptability to layout changes deteriorates
Solution Approach 1:
The lighting system transitions from a static fixed grid to a dynamic reconfigurable arrangement. LED modules can be easily moved, repositioned, and reangled to adapt to changing warehouse layouts, rack configurations, and operational requirements, maintaining comprehensive coverage while providing flexibility for layout changes without requiring complete system replacement.
Solution Approach 2:
The LED modules are designed as universal, multi-functional units that can serve various illumination needs across different locations and configurations. Each module can be positioned to illuminate aisles, rack faces, work stations, or open areas, making the system adaptable to diverse and changing operational requirements while maintaining broad coverage capability.
3Adaptability or versatility
If high intensity discharge lamp fixtures are relocated, then lighting configuration is improved, but installation complexity deteriorates due to heavy weight and conduit requirements
Solution Approach 1:
The patent replaces the heavy mechanical fixture system of high intensity discharge lamps with lightweight LED modules that eliminate the need for robust metal conduit and heavy support structures. The LED modules use low-voltage DC power distribution, substituting the complex high-voltage AC conduit system with simpler wiring, thereby reducing installation complexity while improving lighting configuration flexibility.
Solution Approach 2:
The system undergoes parameter changes by transitioning from high-voltage AC power (requiring heavy conduit and robust fixtures) to low-voltage DC power (enabling lightweight modules and simpler installation). This parameter change fundamentally reduces device complexity and makes lighting reconfiguration much easier while maintaining adaptability to different warehouse layouts.
4Ease of operation
If fluorescent lamps are positioned above storage racks, then accessibility is improved, but light distribution efficiency deteriorates due to wide radiant pattern illuminating unwanted areas
Solution Approach 1:
The LED modules provide localized illumination quality by directing light precisely to rack faces, product labels, and aisle areas where visibility is needed for operations. Unlike fluorescent lamps with wide radiant patterns that waste light on rack tops and unobstructed floors, the LED modules concentrate light where it is most needed, reducing energy waste while maintaining accessibility for forklifts and equipment.
