Monitor Connection Authorization Without Interrupting Display Output
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple devices attempt to connect to a single monitor while an image is being displayed by one device, the display of the existing image is hindered by the monitor displaying an identification code for a new connection, causing disruption and delay in presentations.
Innovation Solution
A method where the monitor transmits authorization request information to a primary connected device, which outputs determination images for user approval, allowing seamless secondary connections without interrupting the primary display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the monitor displays an identification code for a new connection request, then the new device can establish communication with the monitor, but the display of the existing image from the first device is hindered
Solution Approach 1:
The patent divides the display output into two separate channels: the projection surface continues displaying the image from the first communication terminal, while a separate display device shows the identification code for the second terminal's connection request. This segmentation allows both functions to operate simultaneously without interfering with each other.
2Speed
If the monitor prioritizes the new connection request, then the second device can quickly establish communication, but the first device's image display is interrupted
Solution Approach 1:
By separating the display functions into different output devices (projection surface for image data, separate display for identification code), the system allows the second terminal to establish connection quickly without interrupting the first terminal's image display, eliminating the trade-off between connection speed and display continuity.
3Device complexity
If the monitor uses a single display output for both image data and connection information, then the device complexity is reduced, but the adaptability to handle multiple simultaneous connections is limited
Solution Approach 1:
The patent implements a multi-functional system where the projection surface primarily displays image data from the first terminal while the separate display handles connection requests from the second terminal. This universal approach allows the system to accommodate multiple communication terminals simultaneously without requiring complex switching mechanisms.

AI summary
A display system includes a plurality of communication terminals and a monitor capable of communicating with the plurality of communication terminals, the monitor is capable of displaying an image in a display region, first communication between a first communication terminal among the plurality of communication terminals and the monitor is established, when authorization of second communication between a second communication terminal among the plurality of communication terminals and the monitor is requested from the second communication terminal while the image is displayed in the display region, the monitor transmits, to the first communication terminal, information indicating that the authorization of the second communication is requested, the first communication terminal outputs, to the first communication terminal, information for causing a user of the first communication terminal to determine whether to approve the authorization of the second communication, and the monitor establishes the second communication when information indicating that the authorization of the second communication was approved is received from the first communication terminal.
