Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If USB interface is adopted for wireless projection, then ease of connection is improved, but additional USB ports are occupied
Solution Approach 1:
The patent combines image signal transmission and control signal transmission into a single USB Type-C connection. The USB Type-C interface integrates both data and power transmission capabilities, allowing the sender to receive image signals while simultaneously transmitting control signals back to the electronic device through the same physical connection, thereby eliminating the need for additional USB ports.
Solution Approach 2:
The USB Type-C interface is utilized for multiple functions: it serves as both the image transmission channel and the control feedback channel. The interface's bidirectional capability allows it to handle both incoming image data from the electronic device and outgoing control signals to the same device, making a single connection perform the work of multiple connections.
2Ease of manufacture
If application-based wireless projection is adopted, then driver installation is simplified, but operating system compatibility is limited
Solution Approach 1:
The system enables self-service operation by automatically establishing wireless projection without requiring manual driver installation or software configuration. The USB Type-C connection is automatically recognized by the electronic device, and the wireless projection function activates seamlessly, allowing users to connect without technical knowledge of drivers or software installation procedures.
Solution Approach 2:
The patent replaces the software-based application approach with a hardware-level USB Type-C connection approach. By utilizing the native capabilities of the USB Type-C interface for both image and control transmission, the system eliminates the need for operating system-specific applications, thereby achieving universal compatibility across different operating systems through hardware standardization rather than software adaptation.

AI summary
A transmission device capable of control feedback comprises a sender and a receiver. The sender electrically connects to an electronic device through USB type-C for receiving an image signal and sending a control signal. A first processing circuit of the sender converts a network packet into the control signal. A first communication circuit of the sender receives the network packet and sends the image signal. The receiver electrically connects to a display device for sending the image signal and receiving the control signal. A second processing circuit of the receiver encapsulates control signal into the network packet. A second communication circuit of the receiver communicably connects to the first communication circuit to send the network packet and receive the image signal.
