Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If light detection method is used to detect preceding or oncoming vehicles, then detection simplicity is improved, but measurement precision deteriorates due to erroneous detection of street lights or neon billboards
Solution Approach 1:
The patent segments the detection process into multiple stages: first extracting continuous coordinate areas from the image, then pairing coordinate areas with similar feature quantities, and finally determining vehicle locations based on paired coordinates. This segmentation allows the system to distinguish between actual vehicle lights and stationary light sources like street lights or billboards, thereby improving measurement precision while maintaining operational simplicity.
2Difficulty of detecting and measuring
If camera imaging is used to capture condition around vehicle, then detection capability is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The patent extracts only the essential information needed for vehicle detection by identifying and pairing coordinate areas with similar feature quantities from the camera image. Instead of processing the entire image data, the system extracts continuous coordinate areas representing light sources, pairs them based on feature similarity, and uses only this extracted information for vehicle location determination. This extraction approach maintains high detection capability while reducing processing complexity.
3Device complexity
If rough controlling capability is used for head lamp control, then device complexity is reduced, but manufacturing precision deteriorates as optimal light distribution pattern cannot be realized
Solution Approach 1:
The patent implements a dynamic head lamp control system that adjusts light distribution patterns based on the paired coordinate information of detected vehicles. The control system dynamically determines appropriate light distribution patterns according to the location and direction of paired coordinate areas, enabling precise light distribution adjustment without requiring overly complex control mechanisms. This dynamic adaptation achieves optimal lighting conditions while maintaining reasonable device complexity.
