USB Type-C Port Automatic Configuration via Cross-Point Switch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The confusion for users in determining which USB Type-C port to use for specific functions, such as data or video, due to the same physical port being used for various signals, leading to frustration when connecting external devices.
Innovation Solution
A custom logic device automatically configures USB Type-C ports by determining the capabilities of an external device connected and instructing a cross-point switch to route the appropriate signal paths, enabling 'plug and play' functionality without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple USB Type-C ports are used to transport various signals (data, video, etc.), then the versatility and adaptability of the computing device is improved, but the ease of operation deteriorates because users cannot determine which port to use for specific functions
Solution Approach 1:
The patent applies LED indicators with different colors (e.g., green, blue, amber) to visually distinguish the functional status and capability of each USB Type-C port. This allows users to quickly identify which port supports which function (data, video, power) without confusion, directly resolving the port identification problem while maintaining multi-signal transport capability
2Reliability
If USB Type-C ports are configured for specific functions (USB storage, Ethernet, video), then the reliability of signal transmission is improved, but the device complexity increases due to automatic configuration requirements
Solution Approach 1:
The patent implements an automatic configuration system where the computing device autonomously detects the connected external device type and automatically routes the appropriate signal through the USB Type-C port without requiring user intervention. The system self-configures by detecting device capabilities and establishing proper signal paths, thereby maintaining reliability while managing complexity through automation
Solution Approach 2:
The patent employs a feedback mechanism where the system continuously monitors the status of USB Type-C ports and connected devices, using this information to dynamically adjust signal routing and port configuration. This feedback loop ensures reliable signal transmission by matching port capabilities with device requirements while automating the configuration process
3Manufacturing precision
If USB Type-C ports replace traditional segregated ports (USB Type-A, HDMI, DP), then the manufacturing precision and standardization are improved, but the ease of operation worsens due to user confusion
Solution Approach 1:
The patent uses color-coded LED indicators to provide visual feedback about each USB Type-C port's functional capabilities, allowing users to easily identify which port to use for specific connections despite all ports having the same physical appearance. This maintains the manufacturing advantages of standardized USB Type-C connectors while compensating for the loss of physical differentiation

AI summary
In some implementations a logic device, such as an embedded controller, automatically configures a universal serial bus (USB) Type-C port by connecting the USB Type- C port to appropriate input/output (I/O) signals. For example, the logic device may receive a notification that an external device is connected to a USB Type-C port of a computing device. The logic device may receive data from a port controller over an internal communication bus associated with the USB Type-C port. Based at least in part on the data, the logic device may determine one or more types of signals that the external device is configured to send, receive, or send and receive. The logic device may instruct a cross-point switch to connect the USB Type-C port to one or more signal paths in the computing device to enable the external device to send/receive the one or more types of signals.
