Virtual Desktop File Redirection via QR Code Web Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual desktop infrastructure (VDI) and desktop-as-a-service (DAAS) systems face inefficiencies in file and folder redirection, particularly when users need to access files from devices other than their primary client, such as smartphones or tablets, as they require installing a virtual desktop client application, which is time-consuming and often restricted by access control policies.
Innovation Solution
Implementing a web server on the client computing device to enable file and folder redirection through image scanning, such as using a QR code, allowing users to share files and folders from nearby devices without the need for a virtual desktop client application on those devices, by establishing a secured HTTP connection and redirecting file input/output operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional file redirection is used from local storage, then file access on virtual desktop is enabled, but access from mobile devices requires client application installation which is time-consuming and restricted by access control policies
Solution Approach 1:
The patent introduces a web server as an intermediary component on the client device that enables file redirection without requiring mobile devices to install the virtual desktop client application. The web server receives file I/O operations from the virtual desktop and redirects them to files on the mobile device through standard web protocols, serving as a mediator between the virtual desktop infrastructure and mobile device file system.
Solution Approach 2:
The web server provides universal access functionality by handling file redirection requests from any device with a web browser, not just mobile devices. It can serve multiple purposes including file sharing, folder redirection, and providing access to local storage from the virtual desktop environment, making the system more versatile and device-agnostic.
2Adaptability or versatility
If virtual desktop client application is installed on multiple devices, then file redirection is enabled, but the process becomes time-consuming and access control policies are violated
Solution Approach 1:
The web server acts as an intermediary that enables multi-device file access without requiring the virtual desktop client application to be installed on each device. By using standard web protocols and a web browser interface, any device can access and share files with the virtual desktop, eliminating the need for device-specific client installations while maintaining versatility.
Solution Approach 2:
The patent replaces the mechanical installation process of the virtual desktop client application with a software-free web-based interface. Instead of requiring users to download, install, and configure client software on multiple devices, the system uses web protocols and a web browser to provide the same file redirection functionality, significantly simplifying the user experience and eliminating installation barriers.
3Ease of operation
If web server is implemented on client device, then file sharing from any device is enabled without installation, but additional network connection and HTTP protocol setup is required
Solution Approach 1:
The web server implementation on the client device provides self-service functionality by automatically handling file redirection requests through standard web protocols. The system configures itself to listen for HTTP requests and redirect file I/O operations without requiring manual network configuration or additional setup steps on the mobile device, as long as basic network connectivity is available.

AI summary
Techniques are described for file/folder redirection for virtual desktops using image scanning. A virtual desktop client establishes a web server on the client computing device. The virtual desktop client detects input requesting file/folder redirection and displays a QR code encoded with the IP address of the web server. A mobile device scans the QR code using a digital camera and launches a web browser to establish a connection with the web server. User input is entered on the mobile device, indicating one or more files/folders to be shared with the virtual desktop. The information identifying the selected files/folders is sent to the client computing device. The selected files/folders are registered with the virtual desktop and the virtual desktop locally mounts a corresponding folder. The client computing device receives file I/O operations from the virtual desktop and redirects the file I/O operations to the mobile device over a secured HTTP connection.
