Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If millimeter wave band wireless communication is used for video/audio transmission, then wireless transmission capability is improved, but video quality deteriorates when data communication is performed simultaneously
Solution Approach 1:
The patent divides the communication functions into separate modules: a first wireless communication module dedicated to video/audio signal transmission and a second wireless communication module dedicated to data communication. This segmentation allows each module to operate independently on different frequency bands, preventing interference between video and data transmissions while maintaining high video quality.
2Device complexity
If single wireless communication system is used, then device complexity is reduced, but ability to perform simultaneous video/audio and data communication is worsened
Solution Approach 1:
The patent combines multiple wireless communication modules with different functionalities into a single communication device. The first wireless communication module handles video/audio transmission while the second module handles data communication, allowing simultaneous operation of both functions within one integrated device without requiring separate external equipment.
Solution Approach 2:
The communication device is designed with multi-functionality by incorporating both video/audio transmission capabilities and data communication capabilities through different wireless modules. This universal design allows the single device to perform multiple communication tasks simultaneously, eliminating the need for separate dedicated devices for each function.
3Ease of operation
If automatic link establishment is implemented, then ease of operation is improved, but security control capability is worsened
Solution Approach 1:
The communication controller performs preliminary actions by automatically establishing communication links and exchanging necessary information between modules before actual video/audio or data transmission begins. This preliminary setup includes configuring the first wireless communication module to relay data communication capability information to the second module, ensuring security and proper configuration are established in advance.
Solution Approach 2:
The system implements feedback mechanisms where the communication controller continuously monitors and manages the communication state between the first and second wireless communication modules. The controller uses feedback from capability exchange and link status to dynamically adjust communication parameters and maintain both automatic operation and security control.

AI summary
According to one embodiment, a communication device connected wirelessly to a source-side communication device includes a wired communication module, first and second wireless communication modules, and a communication controller. The wired communication module transmits a video signal and exchanges a data signal with a sink device via wired communication. The first wireless communication module receives a video signal through a first wireless communication system. The second wireless communication module transmits and receives a data signal through a second wireless communication system. The communication controller performs processing related to a physical address used in the communication system of the wired communication module. The communication controller relays information as to data communication capability exchanged between the sink device and the source device, and exchanges information as to data communication capability with the source-side communication device. When the devices are capable of data communication, the communication controller sets data communication as possible.
