Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple input/output units are provided to support multiple computers and input/output devices, then the system's adaptability and functionality are improved, but the complexity of selecting correct connections increases and ease of operation deteriorates
Solution Approach 1:
The system performs automatic connection setting by itself without requiring user intervention. The connection setting unit automatically determines which input port corresponds to which output port by detecting image changes, eliminating the need for users to manually configure complex connections between multiple computers and input/output devices.
Solution Approach 2:
The system performs preliminary connection configuration automatically before user operation. By pre-establishing the correct mapping between input and output ports through automatic detection, the system prepares the connection state in advance, so users only need to perform simple operations without dealing with complex connection selection.
2Adaptability or versatility
If multiple input/output units are provided to establish electrical connections between computers and input/output devices, then the system's functionality is improved, but the complexity of the switching device increases
Solution Approach 1:
The system uses feedback from image change detection to automatically determine connection mappings. The detection unit monitors image changes on the display, and this feedback information is used by the connection setting unit to automatically configure the correct input-output port combinations, eliminating the need for complex manual switching mechanisms.
Solution Approach 2:
The patent replaces complex mechanical switching mechanisms with an automated detection and configuration system. Instead of using physical switches or complex routing hardware, the system uses image processing and automatic port mapping to manage connections, significantly reducing device complexity.
3Ease of operation
If automatic connection setting is implemented to simplify user operations, then ease of operation is improved, but the need for detection mechanisms increases device complexity
Solution Approach 1:
The display device performs multiple functions: it displays images from connected computers and simultaneously uses those same display images for connection detection. The display unit serves both as the output interface for users and as the detection target for automatic connection setting, eliminating the need for separate detection hardware.
Solution Approach 2:
The display image acts as an intermediary that bridges the connection between input and output ports. By detecting changes in the displayed image, the system can infer connection status without requiring direct communication between ports or additional detection hardware, simplifying the overall system architecture.

AI summary
An information processing system includes a CPU, computers, and a display device that displays a display screen including videos or images transmitted from the computers on a display. The display device includes a first input port to a fourth input port for receiving a video signal transmitted from each of the computers and a first output port to a fourth output port for outputting an operation signal to each of the computers. The CPU outputs a detection signal for changing the image to each of the first output port to the fourth output port, detects a change in the image on the display screen, and sets a combination of the output port that has output the detection signal and the input port corresponding to the display screen in which the image has changed.
