Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wavelength LEDs are used to provide creative graphical control, then lighting versatility is improved, but operational complexity increases
Solution Approach 1:
The lighting fixture is divided into multiple independently controllable LED groups, each group containing LEDs of different wavelengths (colors). Each group can be controlled separately to create various graphical patterns and lighting effects, enabling versatility while maintaining manageable operational complexity through modular control.
Solution Approach 2:
Graphical content programs are pre-stored in memory before operation. These programs contain predetermined patterns and sequences for controlling the multiple LED groups. During operation, the processor simply retrieves and executes these pre-programmed sequences, eliminating the need for real-time complex adjustments and reducing operational complexity.
2Measurement precision
If manual adjustment of intensity and color levels is required, then lighting precision is improved, but time consumption increases
Solution Approach 1:
The system automatically controls the intensity and color levels of multiple LEDs based on pre-stored graphical content programs. The processor retrieves these programs from memory and automatically adjusts each LED group's output according to the stored patterns, eliminating manual adjustment requirements while maintaining precise lighting control and significantly reducing time consumption.
3Productivity
If graphical content is pre-stored in memory, then productivity is improved, but device complexity increases
Solution Approach 1:
The system replaces manual mechanical adjustment processes with an automated electronic control system. A processor retrieves graphical content programs from memory and automatically controls the LED groups, substituting manual operations with electronic automation. This improves productivity by eliminating time-consuming manual adjustments while the added electronic components represent a manageable increase in system complexity.
