Virtual Desktop Sharing for Cross-Device Application Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices cannot share applications installed on them with other devices that do not have the application installed, limiting cross-device functionality.
Innovation Solution
An electronic device with a processor, working screen, and sharing screen is configured to create a virtual desktop, assign it to the sharing screen, execute an application, and share either the virtual desktop or the window frame of the application with a remote computer device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an application is installed on one electronic device, then the functions of the application can be used on that device, but other electronic devices without the application installed cannot use the application functions
Solution Approach 1:
The patent creates a virtual desktop that copies the application interface and functionality from the host device to a remote device. Instead of transferring or reinstalling the actual application, the system generates a visual and functional replica through screen sharing and virtual desktop technology, allowing the remote device to access application functions without hosting the actual application software.
Solution Approach 2:
The patent introduces a virtual desktop as an intermediary layer between the host device and the remote device. This virtual desktop acts as a mediator that captures the application interface from the host device and transmits it to the remote device, enabling cross-device access without direct application installation or complex peer-to-peer communication protocols.
2Adaptability or versatility
If the entire screen is shared with a remote device, then application functions can be accessed remotely, but the working screen functionality is affected
Solution Approach 1:
The patent divides the screen into two distinct segments: a working screen for local operations and a sharing screen for remote access. This segmentation allows the host device to maintain full local functionality while simultaneously providing remote access to specific content, eliminating the need to choose between local usability and remote accessibility.
Solution Approach 2:
The patent transitions from a single-screen paradigm to a multi-dimensional display architecture where the same application content exists in multiple spatial dimensions simultaneously - the working screen for local interaction and the sharing screen for remote transmission. This dimensional separation allows independent optimization of each screen's purpose without compromising the other.
3Loss of energy
If only the window frame is shared to reduce bandwidth usage, then network efficiency improves, but application functionality may be limited
Solution Approach 1:
The patent applies different quality levels to different portions of the shared content. The window frame structure is transmitted with sufficient detail to maintain application functionality and user interaction capability, while background areas and non-essential elements are transmitted with reduced quality or only when changed. This local quality adjustment ensures functional reliability while minimizing unnecessary bandwidth consumption.

AI summary
An electronic device including a working screen, a sharing screen and a processor is provided. The processor is electrically connected to the working screen and the sharing screen and is configured to: create a virtual desktop of the working screen; assign the virtual desktop to the sharing screen; executes an application; and share the virtual desktop containing a window frame of the application to a remote computer device or share the window frame itself to the remote computer device.
