Innovation Solution
A multi-screen display management system comprising multiple signal input modules, a screen management module, a list modification module, a mode management module, and a driving module that determines active and non-active screens, modifies signal input ports, and drives display devices to display active screens according to user operations, ensuring efficient signal input management across multiple modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single signal input module is used, then the device complexity is reduced, but the number of signal input ports is limited
Solution Approach 1:
The system segments the signal input functionality into multiple independent signal input modules, each with its own set of signal input ports. This allows the system to scale from a single module to multiple modules based on needs, increasing the total number of available ports while keeping each module's complexity manageable and modular.
Solution Approach 2:
The signal input module is designed as a universal component that can function both as a standalone single-module system and as part of a multi-module system. The module structure, control logic, and interface designs are standardized to enable flexible configuration, allowing the same basic module to serve in different system configurations without requiring complete redesign.
2Adaptability or versatility
If multiple signal input modules are provided, then the number of signal input ports increases, but signal input management becomes more complex
Solution Approach 1:
The system merges the control and management functions of multiple signal input modules into a unified management mechanism. The screen management list integrates signals from multiple modules, and the switching control logic provides centralized management, allowing the system to handle multiple modules as a cohesive unit rather than managing each module separately, thus reducing overall management complexity.
Solution Approach 2:
The screen management list and control logic act as intermediaries between the multiple signal input modules and the display device. This intermediary layer abstracts the complexity of managing multiple modules, providing a standardized interface and automated switching logic that simplifies the management process while maintaining full adaptability to different configuration scenarios.
3Reliability
If screen switching is performed without validation, then the switching speed is fast, but signal input module overload occurs
Solution Approach 1:
The system performs preliminary validation checks before executing screen switching operations. The control logic verifies whether the target signal input port and corresponding display screen configuration are valid and whether the signal input module has sufficient capacity to handle the switch. This preliminary action prevents invalid switches and overload conditions, ensuring reliable switching while minimizing unnecessary delays through efficient pre-validation.

AI summary
A multi-screen display management system to effectively manage multi-screen display by creating a screen management list to establish correspondence between each display screen and signal input port. The multi-screen display management system includes a signal input module, a screen management module, a list modification module, a mode management module and a driving module. The screen management module stores a screen management list, in which multiple display screens are pre-defined and a signal input port corresponding to each display screen is recorded. The list modification module is configured to modify the screen management list according to user's operation. The mode management module is configured to determine an active screen in the screen management list according to user's operation. The driving module is configured to drive the display device to display each active screen.
