MR Code Device Pairing via Browser-App Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for device pairing and content sharing between computing devices are cumbersome, requiring manual login and direct connections, which can be time-consuming and insecure, especially when users need to access content on unfamiliar devices.
Innovation Solution
A mobile application generates an MR code that establishes a communication channel with a browser on a client device, allowing users to select and control content remotely through a web-based service, reducing the need for direct connections and manual login processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If users manually login to each device and establish connections, then device pairing and content sharing can be achieved, but the process becomes time-consuming and cumbersome
Solution Approach 1:
The system performs preliminary actions by having users login to their account on one device beforehand. The authentication credentials are stored and automatically reused when the user wants to access content on another device, eliminating the need for repeated manual logins and connection setup processes
Solution Approach 2:
The patent introduces an intermediary authentication system that mediates between devices. Instead of direct manual pairing, the system uses account-based authentication as an intermediary layer that automatically establishes trusted connections between devices, significantly reducing the time and steps required for device pairing
2Reliability
If users enter username and password on unfamiliar devices, then authentication can be performed, but security concerns arise about key stroke logging and surreptitious information use
Solution Approach 1:
The system creates a copy of the authentication credentials that were originally entered on a trusted device. Instead of requiring users to re-enter sensitive information on unfamiliar devices, the system uses the stored authentication copy to automatically verify identity, eliminating the security risk of key stroke logging on untrusted devices
Solution Approach 2:
The patent introduces an intermediary authentication mechanism that acts as a trusted mediator between the user and unfamiliar devices. The system uses pre-stored authentication data as an intermediary layer, so users never have to type their password on potentially untrusted devices, thereby eliminating the harmful factor of surreptitious information capture
3Adaptability or versatility
If direct hard wiring connections are used between mobile device and large screen device, then content streaming can be achieved, but the system becomes less flexible and more complex
Solution Approach 1:
The patent replaces the mechanical physical connection system (HDMI, DVI cables) with an electronic wireless communication system. Content streaming is achieved through wireless networks and digital protocols, eliminating the need for physical cable connections and significantly improving system flexibility and adaptability
Solution Approach 2:
The system extracts and removes the physical connection component from the content streaming architecture. By taking out the mandatory cable requirement and replacing it with wireless communication protocols, the system becomes much more flexible and easier to deploy in various environments without physical connection constraints
4Adaptability or versatility
If pairing mechanisms are used for wireless communication between devices, then direct connections are eliminated, but the pairing process becomes quite time-consuming
Solution Approach 1:
The system performs preliminary authentication actions in advance by storing user credentials and device identification information. When wireless content streaming is needed, the pre-configured authentication data is automatically used to establish the connection, eliminating time-consuming manual pairing steps while maintaining secure wireless communication
Solution Approach 2:
The patent implements self-service authentication where the system automatically handles the pairing process using pre-stored credentials. The devices perform mutual authentication and establish secure wireless connections without requiring user intervention in the pairing process, significantly reducing the time required while maintaining adaptability

AI summary
An MR code is generated within a browser on a client device and is read by a mobile application on a mobile device. A communication channel is then established through a web-based service, between the browser and the mobile application on the mobile device. The mobile application generates a user interface display on the mobile device that allows user selection of content. The mobile application sends a link to that content to the browser, which accesses and renders the content on the client device. User input commands to control the rendered content are also received at the mobile device and sent to the browser through the communication channel.
