Cloud Service for Device Information Storage and Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in configuring multiple devices to communicate with each other, leading to reduced user friendliness and increased complexity.
Innovation Solution
A cloud service maintains device information for multiple devices associated with a user account, allowing credential and remote access information to be shared among devices, enabling them to communicate without individual user configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually configure each device to communicate with one another, then device communication capability is achieved, but user burden and configuration complexity increase
Solution Approach 1:
A cloud service acts as an intermediary between multiple devices, storing device information and credential data centrally. When communication is needed, the cloud service automatically provides the necessary credentials and configuration data to the requesting device, eliminating the need for users to manually configure each device pair.
Solution Approach 2:
The system enables devices to automatically obtain the information they need for communication from the cloud service without user intervention. Devices can autonomously retrieve credential information, device identifiers, and communication parameters by querying the cloud service with their device identifier.
2Adaptability or versatility
If cloud service stores and shares device information automatically, then device interoperability is enhanced, but information security and access control complexity increase
Solution Approach 1:
The cloud service segments device information into distinct types (device identifiers, credential information, communication parameters) and manages access to each type separately based on authorization rules. This allows fine-grained control over what information is shared with which devices while maintaining overall system interoperability.
Solution Approach 2:
The cloud service provides a universal platform that handles multiple functions: storing device information, authenticating devices, providing credentials, and managing communication parameters. This centralized multi-functional approach simplifies security management compared to implementing separate security mechanisms for each device pair.

AI summary
Device information for each of multiple devices associated with a user account is maintained by a cloud service. The device information can include credential information allowing the device to be accessed by other ones of the multiple devices, remote access information indicating how the device can be accessed by other ones of the multiple devices on other networks, and property information including settings and/or device drivers for the device. The device information for each of the multiple devices is made available to other ones of the multiple devices, and can be used by the multiple devices to access one another and provide a consistent user experience across the multiple devices.
