Internal Display Stream Routing via PCIe-USB4 Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of external cables to route display stream data from discrete graphics cards to USB Type-C ports in personal computers is aesthetically unpleasing, costly, and prone to accidental disconnection.
Innovation Solution
Implementing a system within the PC housing that uses Discrete Graphics (DG) circuitry and System-on-Chip (SoC) to route display stream data internally via a USB4 protocol, eliminating the need for external cables by encoding DP packets into PCIe Transaction Layer packets and decoding them back into DP stream data for output through a USB connector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external cables are used to route display stream data from discrete graphics cards to USB Type-C ports, then data transmission can be achieved, but the aesthetic appearance deteriorates and the risk of accidental disconnection increases
Solution Approach 1:
The patent extracts the cable connection function from the external domain and relocates it internally within the device. The display stream data routing is moved from external cables to internal pathways through the housing, eliminating the visible external cables while maintaining the data transmission function. This resolves the contradiction by removing the aesthetic drawback (external cables) while preserving connection reliability through internal routing.
Solution Approach 2:
The patent introduces an intermediary routing mechanism within the device housing that mediates between the discrete graphics card and the USB Type-C port. This internal routing system acts as a mediator, transferring display stream data without requiring external cable connections, thereby improving aesthetic appearance while maintaining reliable data transmission.
2Reliability
If external cables are used to connect discrete graphics cards to USB Type-C ports, then data transmission is possible, but device cost increases
Solution Approach 1:
The patent extracts the costly external cable component from the system and replaces it with internal routing infrastructure that is already present in the device housing. By eliminating the need for external cables and their associated connectors, the overall device cost is reduced while maintaining the essential data transmission capability between the discrete graphics card and USB Type-C port.
3Reliability
If display stream data is routed externally via cables, then data transmission can occur, but the system becomes more complex
Solution Approach 1:
The patent merges the display stream data routing function with the existing internal structure of the device housing. Instead of adding a separate external cable system, the routing is combined with the internal pathways already present in the device, thereby reducing system complexity while maintaining reliable data transmission functionality.
