Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single controller generates and displays multiple types of ship information simultaneously including 3D echo images, then all information can be displayed in one device, but the throughput becomes insufficient due to the large amount of information processing required
Solution Approach 1:
The patent divides the single controller into multiple independent processors (first processor, second processor, graphic processor) that each handle specific image generation tasks. This segmentation allows parallel processing of different ship information types, resolving the throughput bottleneck while maintaining comprehensive display capability.
Solution Approach 2:
The patent combines multiple processors and a graphic processor into an integrated display system that synthesizes their outputs through image synthesis. This merging enables the system to maintain versatile display capabilities while leveraging the combined computational power of multiple processing units to handle large information volumes.
2Manufacturing precision
If higher information processing capability is used to generate 3D echo images from large amounts of echo information, then image quality improves, but the throughput of the controller becomes insufficient when displaying with other ship information
Solution Approach 1:
The patent assigns the computationally intensive 3D echo image generation to a dedicated second processor, separating it from other information processing tasks. This segmentation allows high-quality image generation without compromising the throughput for displaying other ship information simultaneously.
Solution Approach 2:
The graphic processor acts as an intermediary that synthesizes images from multiple processors and outputs the final composite display. This intermediary role allows complex image processing to occur in parallel while maintaining coordinated output, preserving both image quality and overall system throughput.
3Loss of information
If multiple types of ship information are displayed simultaneously, then information completeness improves, but the load on the processor becomes overwhelming
Solution Approach 1:
The patent segments the processing of different information types across multiple specialized processors (first processor for nautical charts, second processor for echo images, etc.). This segmentation distributes the computational load, preventing any single processor from becoming overwhelmed while maintaining complete information display.
Solution Approach 2:
The graphic processor serves as a universal component that handles image synthesis from multiple specialized processors. This multi-functional element coordinates the outputs of various processors, enabling comprehensive information display without concentrating all processing complexity in a single unit.

AI summary
A ship information display device is provided, which may include a first processor, a second processor, a graphic processor, and a display. The first processor may generate a first image based on first ship information received from a first ship sensor and generate a screen to be synthesized including the first image and a blank image. The second processor may generate a second image based on second ship information received from a second ship sensor. The graphic processor may generate a synthesized screen including the first image and the second image by replacing the blank image of the screen to be synthesized by the second image generated by the second processor. The display may display the synthesized screen.
