Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple cable lines are used to connect host device with multiple peripherals and user input devices, then connection reliability is improved, but assembling complexity and occupied space are increased
Solution Approach 1:
The patent combines multiple connection functions (USB host mode, USB device mode, Bluetooth communication) into a single dongle device. This allows the host device to connect with multiple peripherals and input devices through one unified interface rather than requiring separate cable connections for each device, thereby reducing assembling complexity while maintaining connection reliability
Solution Approach 2:
The dongle is designed with multi-functionality to serve as both USB host and USB device, plus Bluetooth communication capability. This universal design enables a single device to replace multiple specialized connection devices, reducing the number of cable lines needed while ensuring reliable connections across different device types
2Reliability
If multiple cable lines are used to connect host device with multiple peripherals and user input devices, then connection reliability is improved, but occupied space is increased
Solution Approach 1:
By merging multiple connection capabilities into a single dongle, the physical space required for multiple cable connections is reduced to the space occupied by one dongle and its associated wireless communication, significantly decreasing the occupied space while maintaining reliable connections
3Device complexity
If current antenna dongles are used to connect peripherals to host device, then assembling complexity is reduced, but communication between multiple host devices is not enabled
Solution Approach 1:
The dongle is designed with universal communication capabilities including USB host mode, USB device mode, and Bluetooth communication. This multi-functionality enables the dongle to facilitate communication between multiple host devices and various peripherals, enhancing adaptability while keeping assembling complexity low
Solution Approach 2:
The dongle acts as an intermediary device that mediates communication between multiple host devices and peripherals. By serving as a central communication hub with multiple interface modes, it enables host devices to communicate with each other and with connected peripherals without requiring direct connections between them

AI summary
The present disclosure provides a wireless communication system including a first host computer, a communication dongle, a second host computer and an input device. The communication dongle is connected to the first host computer via a USB interface, connected to the second host computer via a Bluetooth interface, and connected to the input device via a RF interface. The first host computer has first application software for intercepting the operating signal(s) of the input device and transferring, via the communication dongle, to the second host computer to be executed thereby. The first application software also controls the first host computer to ignore the operating signal(s) during the operating signal(s) is being transferred to the second host computer.
