Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If specific printed circuit boards and optical elements are designed for each luminaire application, then the lighting pattern on the illuminated surface can be precisely controlled, but the production cost increases and the design process becomes time-consuming
Solution Approach 1:
The patent employs a universal printed circuit board design that can be used across multiple luminaire applications. Instead of designing specific PCBs for each application, the invention uses a single standardized PCB combined with adjustable optical elements (lenses or reflectors) that can be positioned at different angles to achieve various lighting patterns. This multi-functional approach allows the same hardware platform to serve pedestrian roads, highways, one-way roads, and other applications, thereby reducing production costs and design time while maintaining precise lighting pattern control through mechanical adjustment of the optical elements.
2Adaptability or versatility
If different optical elements are installed for each site and application, then the light distribution can be optimized for specific uses, but the installation complexity increases and stock keeping requirements expand
Solution Approach 1:
The invention implements a dynamic adjustment mechanism that allows the optical elements (lenses or reflectors) to be mechanically repositioned to different angles and orientations after installation. The luminaire includes an adjustable mounting structure with locking mechanisms that enable field adjustments of the optical elements without requiring different components for each application. This dynamic adaptability allows the same luminaire to be optimized for various sites and uses simply by adjusting the optical element positions, eliminating the need for complex pre-configured optical assemblies and reducing installation complexity.
Solution Approach 2:
The luminaire is designed as a modular system where the optical elements are separate, independently adjustable components rather than fixed integrated assemblies. The optical elements can be individually positioned and locked at different angles, allowing flexible configuration without affecting other parts of the system. This segmentation enables simplified stock keeping (only one type of optical element needed) while maintaining high adaptability to different applications through independent adjustment of each optical element's position and orientation.
3Ease of manufacture
If a standardized luminaire design is used for all applications, then production costs decrease and manufacturing becomes simpler, but the ability to adapt to different sites and applications is reduced
Solution Approach 1:
The invention maintains a standardized luminaire design with fixed physical dimensions and electrical specifications for ease of manufacture, but introduces adjustable parameters through the optical element positioning system. The optical elements can be rotated and positioned at various angles (e.g., 0°, 15°, 30°, 45°, 60°, 75°, 90°) relative to the luminaire housing, creating different light distribution patterns without changing the physical structure. This parameter-based adaptability allows a single standardized design to serve multiple applications while maintaining manufacturing simplicity and economies of scale.
