Multi-device Account Management via Cloud Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Teachers face an inconvenient experience when switching between classrooms with interactive flat platforms (IFPs), as they must manually input accounts, passwords, and install applications in each classroom, leading to an unfriendly usage scenario.
Innovation Solution
A multi-device-multi-account management system that includes a cloud server and user equipment, enabling automatic loading of user information, allowing multiple accounts to log in on the same device, and providing options like QR code scanning and NFC/RFID card bonding for seamless account management across multiple devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If teachers manually input account and password for each classroom IFP, then account security is maintained, but user convenience deteriorates
Solution Approach 1:
The patent introduces a cloud server as an intermediary between the teacher's personal device and the classroom IFPs. The cloud server stores account credentials securely and provides authentication services, allowing teachers to log in via their personal devices without manually entering credentials on each IFP. This resolves the contradiction by maintaining security through centralized credential management while improving convenience through automated authentication.
Solution Approach 2:
The system enables teachers to autonomously manage their own account access across multiple classrooms through self-service login mechanisms. Teachers can use their personal devices to authenticate and automatically access the IFP in any classroom without requiring manual configuration or administrator intervention, thus improving convenience while maintaining security through standardized authentication protocols.
2Productivity
If teachers install applications on each classroom IFP, then application availability is ensured, but time consumption increases
Solution Approach 1:
The patent implements a universal application ecosystem where teaching applications are deployed on the cloud server and can be accessed from any classroom IFP through the cloud connection. Teachers can access the same application suite across all classrooms without installing applications locally on each IFP, resolving the contradiction by ensuring application availability through cloud-based universal access while eliminating the time-consuming installation process on each device.
Solution Approach 2:
The system creates virtual copies of the application environment on each classroom IFP through cloud streaming or remote desktop technology. Instead of physically installing applications on each device, the IFP streams the application interface from the cloud server, giving the appearance of local installation while actually delivering applications on-demand from a centralized source, thus maintaining application availability without the time cost of repeated installations.
3Ease of operation
If teachers configure favorite usage scenario on each IFP, then device customization is achieved, but setup complexity increases
Solution Approach 1:
The patent merges the configuration management of multiple IFPs into a single unified process through the cloud server. When a teacher configures their favorite usage scenario on one IFP, the configuration is automatically synchronized to all other classrooms through the cloud, eliminating the need to repeat configuration on each device. This resolves the contradiction by achieving device customization across all classrooms while reducing setup complexity through centralized configuration management.
Solution Approach 2:
The system performs preliminary configuration actions automatically when a teacher first uses an IFP. The cloud server detects the new device, pre-configures it with the teacher's profile and favorite settings, and prepares the environment before the teacher arrives. This eliminates the need for manual setup on each device, achieving customization while minimizing setup complexity through advance automated preparation.
4Adaptability or versatility
If multiple user accounts are allowed on the same IFP, then device utilization is improved, but account management complexity increases
Solution Approach 1:
The cloud server acts as an intermediary that manages multiple user accounts and their permissions centrally. Instead of managing multiple accounts directly on each IFP, the cloud server authenticates users and delivers personalized content to the appropriate IFP. This resolves the contradiction by improving device utilization through shared access while reducing account management complexity by moving it to the cloud where it can be managed uniformly across all devices.

AI summary
A multi-device-multi-account management system includes: a cloud server and a plurality of user equipment communicating with the cloud server. The cloud server includes an AMS for providing a plurality of log-in options and a DMS for managing the plurality of user equipment. The plurality of log-in options include after a user account logging in, the AMS providing automatic introducing personal information into an user equipment which the user account logs in. The AMS generates a QR code which is corresponding to the user account. The user equipment scans the QR code to log into the AMS.
