USB Type-C Connector Bidirectional Data Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices with USB type-C connectors can only transmit data to external devices but not receive user input, limiting user control over the displayed screen image when connected through a USB type-C interface.
Innovation Solution
An electronic device equipped with a USB type-C connector, a display, and a processor that senses connections with external devices, receives user input data through the connector, and controls the device based on this input, enabling bidirectional communication and user control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the electronic device transmits data to the external electronic device through the USB type-C connector, then the data transmission capability is improved, but the ability to receive user input from the external electronic device deteriorates
Solution Approach 1:
The USB type-C connector is configured to perform multiple functions: it can both transmit data from the electronic device to the external electronic device and receive user input data from the external electronic device. The connector includes multiple pins that enable bidirectional communication, allowing the same physical interface to serve both data output and user input control purposes.
2Adaptability or versatility
If the USB type-C connector is used for charging and data transmission, then the connectivity function is improved, but the user control capability over the displayed screen image deteriorates
Solution Approach 1:
The USB type-C connector is divided into multiple functional pins, where specific pins are designated for different purposes. Some pins are configured for power transmission and data output, while other pins are specifically allocated to receive user input signals from the external electronic device's input/output component, enabling screen control functionality.
3Productivity
If the electronic device functions as a host transmitting data to the external device, then the data output capability is improved, but the bidirectional communication capability deteriorates
Solution Approach 1:
The roles of the electronic device and external electronic device are dynamically adjustable. The electronic device can function as a host for data transmission, but also accepts user input from the external device through dedicated pins. This dynamic role assignment enables bidirectional communication where the electronic device both outputs data and receives control signals.
