Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a servo network is used for transmitting and sharing media between computers, then media sharing functionality is achieved, but system cost and network construction complexity increase significantly
Solution Approach 1:
The patent introduces a data bridge device as an intermediary component that connects two computers via USB interfaces. This mediator enables bidirectional transmission of media data (displayed image, keyboard, cursor, and sound) without requiring complex servo networks. The data bridge converts and transmits media data in USB data format, simplifying the network architecture while maintaining full media sharing functionality.
Solution Approach 2:
The patent replaces the mechanical servo system with an electronic data transmission system based on USB interfaces. Instead of using servo devices for media transmission, the invention uses software-based switching control modules that operate within the operating systems of the computers, substituting mechanical control with electronic software control through the data bridge.
2Adaptability or versatility
If a servo system is adopted for interactive media operation between computers, then media interaction is enabled, but hardware resource utilization becomes inefficient and costs increase
Solution Approach 1:
The patent makes existing computer hardware resources universal and multi-functional. The switching control modules enable computers to function both as controlling sides and controlled sides, allowing the same hardware resources to be shared bidirectionally. This eliminates the need for dedicated servo resources, as existing USB interfaces, processors, and display devices are utilized for media sharing, improving hardware resource efficiency while enabling interactive media operation.
Solution Approach 2:
The computers themselves perform the media sharing function through their own hardware resources (USB interfaces, processors, display devices) without requiring external servo systems. The switching control modules within each computer enable them to autonomously control and share their media resources, making the system self-sufficient and eliminating waste of hardware resources on dedicated servo equipment.
3Device complexity
If USB interfaces and data bridge are used for media transmission, then system cost and network construction are simplified, but bidirectional switching control between computers must be implemented
Solution Approach 1:
The data bridge serves as an intermediary that facilitates bidirectional communication between the two computers. It receives media data from either computer via USB interfaces, performs format conversion if necessary, and transmits the data to the other computer. This intermediary approach simplifies the network construction by using standard USB connections while enabling automated bidirectional switching control through software-based switching modules.

AI summary
A media sharing device includes a data bridge device and two switching control modules. The data bridge device has two terminals connected to USB interface ports of two computers and provides bi-directional transmission of media of displayed image, keyboard, cursor, and sound of the computers in USB data format between the computers. Switching control modules are mounted in the computers and are activated by an associated activation device to switch the controlling side and controlled side of the computers. The controlling side computer transmits data of displayed image, keyboard, cursor, and sound to the controlled side computer for computer display, executing the displayed image, keyboard, cursor, and sound supplied from the controlling side computer, or the activation device of the controlled side computer is activated to issue an instruction to the controlling side computer to switch the controlling side and the controlled side of the computers.
