Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional outdoor lighting systems are used, then lighting function is provided, but the system is cumbersome and difficult to adapt to user-specific needs
Solution Approach 1:
The lighting system is divided into multiple independently controllable LED modules arranged in curved configurations. Each module can be individually addressed and controlled via DMX512 protocol, allowing flexible adaptation to different user needs without requiring complex system-wide redesign. The segmentation enables modular assembly and configuration.
Solution Approach 2:
The system incorporates programmable logic controllers (PLCs) that enable dynamic adjustment of lighting parameters including intensity, color temperature, and timing sequences. The lighting configuration can be dynamically reprogrammed through pulse-width modulation to adapt to different operational scenarios and user preferences.
2Ease of operation
If multiple LED configurations and curved housings are used, then flexibility and user control are improved, but circuitry complexity increases
Solution Approach 1:
A universal control system based on DMX512 protocol is implemented that can address and control all LED modules through a single communication channel. The PLC-based control architecture provides multi-functional capabilities including intensity control, color temperature adjustment, and timing sequences, reducing the need for multiple separate control circuits.
Solution Approach 2:
The PLC acts as an intermediary device that receives high-level control commands and translates them into individual LED module control signals. This intermediary layer simplifies the control interface for users while managing the complexity of driving multiple curved LED configurations through pulse-width modulation.

AI summary
An outdoor lighting device is disclosed having a vertical stand and a curved rigid housing disposed about a top of the stand coupled to a power source, wherein the curved housing has a curved planar surface having a radius of curvature. The curved housing has an outside side and an inner side, the inner side having a curved COB LED assembly with a radius of curvature that is substantially the same as the radius of curvature of the housing. A gear is coupled to the stand and the curved housing and is configured to permit the curved housing to be rotated 360 degrees radially with respect to the stand and 90 degrees vertically with respect to the stand.
