Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional lighting systems are used, then the structure is simple, but the information exchange and communication capability between traffic participants is insufficient
Solution Approach 1:
The lighting system is divided into multiple independently controllable light sources arranged in a matrix array, where each light source can be individually controlled to display different patterns, colors, and intensities. This segmentation enables complex information communication while maintaining modular simplicity in the overall system architecture.
Solution Approach 2:
The lighting display device integrates multiple functions including illumination, information display, communication signals, and warning functions into a single system. The same matrix light source array can perform different functions by varying the control patterns, eliminating the need for separate dedicated devices for each function.
2Adaptability or versatility
If multiple light sources are independently controlled for pixelated display, then the information communication capability is improved, but the light interference and dazzling effect increase
Solution Approach 1:
Light shields are strategically positioned between adjacent light sources to extract and block the harmful lateral light radiation. Each light shield is specifically designed to block light from neighboring light sources while allowing the intended light to pass through, thereby eliminating interference without affecting the display capability.
Solution Approach 2:
The light shields are selectively placed only where needed between specific light sources based on the display pattern requirements. The shielding structure is optimized locally at each light source position rather than applying uniform shielding across the entire array, maintaining display quality while reducing interference.
3Measurement precision
If light shields are added to prevent interference, then the light control precision is improved, but the device complexity increases
Solution Approach 1:
The light shields are integrated with the light source modules in a combined structure where the shields form part of the housing or mounting structure for the light sources. This merging reduces the number of separate components and simplifies assembly while maintaining the precise light control functionality.
Solution Approach 2:
The light shields are nested within the overall lighting assembly structure, positioned inside the housing or mounting framework. This nesting approach allows the shields to be incorporated without significantly increasing the external dimensions or complexity of the device.
