Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If cable connections are used between modules and network cables between cabinets for signal transmission, then video information can be transmitted between different modules and cabinets, but the cable connections occupy a lot of space inside the cabinet, which is not conducive to the thinning of the screen
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. Specifically, it uses wireless communication modules (such as Wi-Fi, Bluetooth, or other wireless protocols) to transmit video signals between cabinets and modules, eliminating the need for physical cable connections. This substitution directly reduces the space occupied inside cabinets and enables screen thinning while maintaining signal transmission functionality.
2Reliability
If cable connections are used between modules and network cables between cabinets, then video information can be transmitted, but the connections are complicated, which is not conducive to disassembly and maintenance, and is prone to open circuit due to poor contact
Solution Approach 1:
The patent replaces mechanical cable connections with wireless communication modules integrated into each cabinet and module. This eliminates physical connectors that are prone to poor contact and open circuits, thereby improving connection reliability.同时, it greatly simplifies disassembly and maintenance as no cable connections need to be handled during these operations.
3Stability of the object's composition
If network cables are used to connect different cabinets, then video signals can be transmitted between cabinets, but an open channel is required between cabinets to supply the cable, which is not conducive to the sealing of the cabinet
Solution Approach 1:
The patent replaces the need for physical cable routing through open channels with wireless communication. Each cabinet is equipped with wireless communication modules that transmit video signals through the air, eliminating the requirement for open channels and maintaining complete cabinet sealing. This improves both the sealing stability and aesthetic appearance of the cabinets.
4Ease of operation
If cable connections and network cables are used for signal transmission, then video information can be transmitted between modules and cabinets, but signal control and system debugging become more complicated due to multiple factors such as line connection, cabinet location, wiring method, and wiring location
Solution Approach 1:
The patent replaces complex wired signal control systems with wireless communication modules that automatically establish connections. The wireless system eliminates the need for manual wiring configuration, cabinet location-based routing decisions, and connection verification. System debugging becomes simpler as there are no physical connections to verify, and the wireless protocol handles automatic connection establishment and signal routing.
5Reliability
If multi-channel serial port wiring is used for communication, then information can be transmitted between cabinets, but it has high requirements on the environment, requiring the cabinet to have good air tightness and waterproof performance
Solution Approach 1:
The patent replaces multi-channel serial port wiring with wireless communication modules. This substitution eliminates the need for physical communication channels that are vulnerable to environmental factors such as moisture, dust, and air quality. Wireless communication occurs through electromagnetic waves in the air, requiring no physical openings in the cabinet, thereby maintaining air tightness and waterproof performance while ensuring reliable communication.
