Sharing Expansion Device for Multi-User Concurrent Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current computer hardware improvements are exclusive to single users, limiting multiple users from concurrent and independent operation, even with multiple input devices, as they can only share the same user account and operating frame.
Innovation Solution
A sharing expansion device and method that enables multiple user accounts to log in concurrently, using time division multiplexing to execute commands from different users through separate input devices and monitors, allowing independent operation and shared system resources without logging out existing users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple users operate the computer through the same user account and operating frame, then the computer resources can be shared, but the users cannot operate independently and must share the same operating interface
Solution Approach 1:
The patent divides the single operating frame into multiple independent virtual frames, allowing each user to have their own operational interface within the same physical computer. This segmentation enables multiple users to operate independently while sharing system resources, resolving the contradiction between resource sharing and independent operation capability
Solution Approach 2:
The patent introduces a virtual dimension layer above the physical hardware, creating virtual frames that overlay the physical monitor. This dimensional transformation allows multiple users to access the same physical resources through different virtual interfaces simultaneously, enabling both resource sharing and independent operation
2Adaptability or versatility
If a user logs out to allow another user to log in, then user account switching is enabled, but continuous operation by multiple users is prevented
Solution Approach 1:
The patent pre-allocates multiple user accounts and their corresponding virtual frames before operation begins. Each user account is prepared with its own operational environment, allowing users to log in simultaneously without requiring logout/login cycles, thus enabling continuous multi-user operation while maintaining account security and separation
3Adaptability or versatility
If multiple input devices are connected for multiple users, then hardware connectivity is improved, but the users still cannot operate independently without separate user accounts
Solution Approach 1:
The patent makes the single computer system serve multiple user functions simultaneously by creating virtual frames for each user. Each input device is associated with a specific user account and virtual frame, allowing the system to handle multiple user operations through a unified hardware platform, thereby reducing device complexity while maintaining operational independence
