Vehicle Lamp Image Overlap Control for Distortion-Free Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image distortion occurs when two lamps on a moving object, such as a vehicle, output a single image, particularly in the center portion due to overlapping areas, which can result in empty or overlapping images.
Innovation Solution
A lamp system with a control unit that allocates and adjusts the first and second images to be output by the left and right lamps, respectively, by modifying the transparency and brightness of overlapping areas, ensuring the images are divided and output without distortion, and includes a sensor to adjust the overlapping area based on the distance between the projection surface and the moving object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the left and right lamps divide and output one image separately, then the lighting function is achieved, but image distortion occurs in the center portion due to overlapping areas
Solution Approach 1:
The patent applies local quality by adjusting the transparency and brightness parameters specifically in the overlapping area of the two lamps' images. The control unit modifies only the overlapping region's properties (transparency gradually lowered, brightness gradually lowered) while leaving other areas unchanged, thereby resolving the image distortion problem locally without affecting the overall image output mechanism
Solution Approach 2:
The patent employs parameter changes by dynamically adjusting transparency and brightness values in the overlapping area. The control unit changes these parameters based on the distance between the projection surface and the moving object (detected by sensor), allowing the system to adapt to different viewing conditions and eliminate image distortion across various scenarios
2Manufacturing precision
If the lamps output one image together, then the image completeness is maintained, but the center portions may be empty or overlap due to image processing errors
Solution Approach 1:
The patent implements feedback by using a sensor to detect the distance between the projection surface and the moving object, then feeding this information back to the control unit. The control unit adjusts the overlapping area size and transparency/brightness parameters based on this feedback, creating a closed-loop system that automatically compensates for image alignment issues and maintains reliable image output under varying conditions
Solution Approach 2:
The patent applies dynamics by making the overlapping area size and transparency/brightness parameters dynamic rather than fixed. The system continuously adjusts these parameters based on real-time distance measurements, allowing the image processing to adapt to changing viewing conditions and prevent center portion emptiness or overlap

AI summary
A lamp system capable of improving ease of use by outputting an image without distortion when one image is divided and output from left and right lamps, respectively. The lamp system includes a left lamp (220) installed on a left side of a moving object in one direction to output an allocated first image (21), a right lamp (230) installed on a right side of the moving object in one direction to output an allocated second image (31), and a control unit receiving original image information from the outside to allocate the first image (21) and the second image (31) to the left lamp (220) and the right lamp (230), respectively, based on the original image but change and allocate an overlapping area (22, 32) that is an overlapping portion of the first image (21) and the second image (31).
