Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a circuit device is prepared with the number of output terminals corresponding to the maximum resolution of a display, then the display can be supported, but the chip size increases
Solution Approach 1:
The patent implements a switching circuit that can dynamically allocate any combination of output terminals to different displays based on their resolution requirements. Instead of having dedicated terminals for each display configuration, the same set of output terminals can be reconfigured to support various display resolutions and arrangements, making the circuit device universally applicable to multiple display scenarios without increasing chip size
Solution Approach 2:
The patent employs a dynamic allocation mechanism where the switching circuit can flexibly assign output terminals to displays in real-time based on detected resolution requirements. This dynamic reconfiguration allows the system to adapt to different display configurations (e.g., single display, dual display, varying resolutions) using the same physical hardware, thereby supporting maximum resolution displays without permanently allocating all terminals for that purpose
2Productivity
If custom circuit devices are prepared for different display resolutions, then the data transmission can be optimized, but the device complexity increases
Solution Approach 1:
The patent creates a single universal circuit device design that can handle multiple display resolutions and configurations through software-controlled terminal allocation. The switching circuit responds to display resolution information and dynamically configures which output terminals are active, eliminating the need to manufacture different hardware versions for different resolutions while maintaining optimal data transmission for each scenario
Solution Approach 2:
The patent changes the operational parameters of the output terminals dynamically based on display resolution requirements. The switching circuit adjusts which terminals are enabled and how they are configured based on the detected display characteristics, allowing the same physical circuit to optimize data transmission for different resolutions without requiring custom hardware designs for each case

AI summary
A circuit device includes an image splitting circuit, a first output terminal group to an n-th output terminal group, and a switching circuit. The image splitting circuit splits input image data into first image data and second image data. The switching circuit allocates the first image data to any i output terminal groups among the first output terminal group to the n-th output terminal group, and outputs the first image data from the i output terminal groups to a first display. The switching circuit allocates the second image data to any j output terminal groups among output terminal groups obtained by excluding the i output terminal groups from the first output terminal group to the n-th output terminal group, and outputs the second image data from the j output terminal groups to a second display.
