1Reliability

If two video interfaces are used to output images for left and right headlamps, then image output capability is ensured, but material costs increase

Engineering Contradiction:
Improveimage output capabilityVSAvoidmaterial costs
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent combines two separate video interfaces into a single video interface by using a serializer to multiplex video data for both left and right headlamps. This merging approach reduces the number of image processors from two to one, thereby lowering material costs while maintaining the capability to output images for both headlamps simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single video interface and image processor are designed to handle multiple functions by generating video data for both left and right headlamps through serialization. The system achieves multi-functionality where one interface serves the purpose of two interfaces, reducing hardware requirements while ensuring reliable image output for both lamps.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Manufacturing precision

If two image processors are used to generate video images for both lamps, then image quality is maintained, but device complexity increases

Engineering Contradiction:
Improveimage qualityVSAvoidnumber of image processors
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent merges two image processors into one by implementing a serialization mechanism that allows a single image processor to generate video data for both left and right headlamps. This reduces device complexity by eliminating redundant hardware while maintaining image quality through proper video data generation and timing control.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The video data generation process is segmented into different time slots or data streams within the single image processor, allowing it to handle both left and right headlamp images sequentially or in parallel through multiplexing. This segmentation enables one processor to perform the work of two without compromising image quality.

Inventive Principle:
Principle #1Segmentation
