Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high pixel density electroluminescent light sources are used to enable precise illumination control, then illumination precision and anti-glare function are improved, but device complexity increases due to the need for individual control of each pixel
Solution Approach 1:
The light source is divided into multiple independently controllable pixels arranged in a matrix, where each pixel can be individually controlled to illuminate specific areas of the road. This segmentation enables precise illumination control and anti-glare functions by selectively activating or deactivating individual pixels based on detected objects or conditions.
Solution Approach 2:
The patent transitions from conventional single-point or simple array light sources to a two-dimensional matrix arrangement of pixels. This dimensional change from one-dimensional or point sources to a two-dimensional grid enables spatially selective illumination control, allowing precise targeting of specific road areas while maintaining manageable control architecture through matrix-based addressing.
2Device complexity
If conventional light sources are used, then device complexity is reduced, but illumination precision and ability to perform anti-glare functions deteriorates
