Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple display modules are connected through long distances to form a large-sized display, then the display area is increased, but data communication reliability and speed are reduced
Solution Approach 1:
The patent divides the display system into multiple independent display modules that can be connected in various configurations. Each module operates semi-independently with its own controller, allowing the system to achieve large display area while maintaining communication reliability through segmented, modular connections rather than a single long communication path.
Solution Approach 2:
The patent introduces a feedback loop mechanism that adds a dimensional aspect to the communication architecture. By implementing bidirectional communication with feedback paths between adjacent modules, the system creates additional communication dimensions that enable synchronization and reliability maintenance despite long physical distances between modules.
2Area of stationary object
If multiple display modules are connected through long distances, then the display area is increased, but data communication speed is reduced
Solution Approach 1:
The patent segments the communication path into shorter segments between adjacent modules. Each module communicates with its immediate neighbors through localized interfaces, reducing the effective communication distance and maintaining high data communication speed while still achieving large overall display area through modular expansion.
Solution Approach 2:
The feedback loop mechanism enables continuous synchronization between modules, maintaining stable clock signals and data communication across the entire display system. This continuous action prevents signal degradation and maintains communication speed despite the extended physical distance covered by multiple modules.
3Area of stationary object
If multiple display modules are connected through long distances, then the display area is increased, but synchronization between clock and data becomes difficult
Solution Approach 1:
The patent implements feedback loops where each display module sends synchronization signals back to its neighbors. This feedback mechanism enables automatic adjustment and maintenance of clock and data synchronization across all modules, ensuring stable operation even when modules are connected over long distances to form large displays.
Solution Approach 2:
The patent creates a universal synchronization architecture where the same feedback loop mechanism serves multiple functions: clock synchronization, data timing coordination, and reliability verification. This multi-functional approach simplifies the challenge of maintaining synchronization across large-scale display systems.
