Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional collaboration platforms fail to achieve effective screen synchronization across display devices with different resolutions and screen sizes, leading to incomplete display content for users.
Innovation Solution
A collaboration system and method that includes a first and second display device with processors and communication devices, enabling frame and mouse synchronization through event data exchange and frame range adjustment, using a server for communication, to ensure consistent display across devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screen synchronization is implemented across display devices with different resolutions and screen sizes, then collaborative display effectiveness is improved, but device complexity increases due to frame range calculation and adjustment mechanisms
Solution Approach 1:
The patent introduces a server as an intermediary that receives event data from display devices, calculates frame ranges, and sends control instructions back to devices. This externalizes the complex calculation logic from individual devices to a centralized server, resolving the technical contradiction by maintaining synchronization reliability while reducing individual device complexity.
Solution Approach 2:
The patent dynamically adjusts display parameters (frame range, position, size) based on real-time event data and device characteristics. By changing these parameters adaptively, the system achieves effective screen synchronization across devices with different resolutions and screen sizes without requiring complex hardware modifications.
2Reliability
If frame synchronization is achieved across different display devices, then display consistency is improved, but communication data volume increases due to event data exchange
Solution Approach 1:
The patent extracts only the essential event data (mouse position, frame position, frame size) needed for synchronization from the full device state, and transmits only this minimal necessary data to the server. This selective extraction approach maintains display consistency while minimizing communication data volume by transmitting only critical synchronization information.
3Speed
If real-time frame following is implemented, then collaborative interaction responsiveness is improved, but processing load increases on display devices
Solution Approach 1:
The server acts as a computational intermediary that handles the heavy processing load of frame range calculation and synchronization logic. Individual display devices only need to send event data and receive instructions, significantly reducing their processor load while maintaining real-time responsiveness through the centralized coordination provided by the server.

AI summary
A collaboration system and a collaboration method are provided. The collaboration system includes a first display device and a second display device. The first display device includes a first screen. The first screen displays a first display interface. The first display interface has a first display window and a first function key. The first display window displays a first frame. The second display device includes a second display screen. The second display screen displays a second display interface. The second display interface has a second display window. The second display window displays a second frame. When the first function key is turned on, the first frame moves along with the second frame. When the first function key is turned off, the first frame does not follow the movement of the second frame.
