Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication is used for data transmission in display devices, then data transmission rate and reliability are improved, but movement freedom and ease of operation deteriorate
Solution Approach 1:
The patent replaces the mechanical wired communication system with a wireless communication system using RF signals. The transmitter converts display signals to RF signals for wireless transmission, and the receiver converts received RF signals back to display signals, eliminating physical cables and connectors while maintaining data transmission functionality.
Solution Approach 2:
The patent changes the transmission medium from electrical signals through cables to electromagnetic RF signals through air space. By using extremely high frequency (EHF) band RF signals with frequencies of 30 GHz or more, the system achieves both wireless freedom of movement and reliable high-speed data transmission suitable for display devices.
2Ease of operation
If wireless communication is used to enable movement freedom, then ease of operation is improved, but protocol compatibility and device adaptability deteriorate
Solution Approach 1:
The patent introduces a protocol conversion function as an intermediary between wireless communication and display signal transmission. The transmitter includes a conversion unit that converts display signals to RF signals according to wireless communication protocols, while the receiver includes a conversion unit that converts received RF signals back to display signals, enabling compatibility between different protocols and devices.
Solution Approach 2:
The wireless communication system is designed to handle multiple communication protocols universally. The transmitter and receiver can convert between different display signal interfaces (HDMI, DisplayPort, V-by-One) and wireless RF signals, allowing a single wireless communication device to work with various types of electronic devices regardless of their native protocol.
3Adaptability or versatility
If protocol conversion function is added to enable compatibility between different devices, then device adaptability is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent merges the protocol conversion function directly into the wireless communication chipset. The transmitter integrates signal conversion to RF and wireless transmission functions in one unit, while the receiver integrates RF reception and signal conversion functions, reducing the need for separate conversion devices and simplifying the overall system architecture.
Solution Approach 2:
The wireless communication system performs automatic protocol detection and conversion without requiring manual configuration or user intervention. The transmitter and receiver automatically identify the communication protocol and perform appropriate signal conversion, making the system easy to use despite the underlying complexity of supporting multiple protocols.
