Solution Overview

Problem

Current computing devices do not allow multiple users to simultaneously access and present their own content files during a collaborative session without requiring users to log out or switch between accounts, leading to security concerns and confusion regarding file edits.

Innovation Solution

A computing device configured to provide a unified collaborative session where multiple users can be authenticated and access their own accounts and content files simultaneously, with a permissions manager to control access and track edits, and a roster module to distribute content files, allowing seamless collaboration while maintaining security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple users simultaneously access a computing device, then collaboration capability is improved, but user account security and control are worsened

Engineering Contradiction:
Improvecollaboration capabilityVSAvoiduser account security
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The computing device segments user access by creating separate user accounts and content portals for each authenticated user. Each user has their own content portal that isolates their files and preferences, allowing simultaneous access without compromising individual account security. The system divides the shared display into separate viewing zones associated with each user.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces a permissions manager as an intermediary between users and content files. This mediator handles authentication, authorizes access to specific content based on user permissions, and manages the collaborative session. The permissions manager acts as a gatekeeper that allows multiple users to access the system simultaneously while maintaining security controls.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If users can simultaneously access content files, then collaboration efficiency is improved, but edit attribution confusion is worsened

Engineering Contradiction:
Improvecollaboration efficiencyVSAvoidedit attribution clarity
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The system implements feedback mechanisms through a unified collaborative session interface that displays real-time information about which user made each edit to content files. The interface provides visual feedback showing edit attributions, allowing users to see who made changes and when. This feedback loop prevents confusion by continuously updating the display with edit metadata.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system adds a new dimension of information display by showing edit metadata and user attribution alongside the content itself. Instead of just displaying the content, the system overlays additional information about the edit history and authorship, creating a multi-dimensional interface that presents both content and contextual information simultaneously.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If one user logs out to allow another user access, then account security is maintained, but collaboration continuity is worsened

Engineering Contradiction:
Improveaccount securityVSAvoidcollaboration continuity
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary authentication of multiple users before they need to access content. Users can be authenticated and have their content portals pre-configured before the collaborative session begins. This preliminary setup allows multiple users to simultaneously access their files without needing to log out and log in during the collaboration, maintaining both security and continuity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The unified collaborative session maintains continuous operation for multiple authenticated users without interruption. Once users are authenticated, they can continuously access their content files and collaborate in real-time without logging out. The system preserves the state of all user sessions simultaneously, ensuring continuous useful action for all participants.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A computing device includes a touch-sensitive user interface configured to present a unified collaborative session for two or more users, and an authentication module configured to simultaneously identify and authenticate multiple users physically co-located within a collaborative environment, allowing each of the multiple users to touch interact with the touch-sensitive user interface. A content module is configured to simultaneously provide one or more content portals within the unified collaborative session for each authenticated user. Each content portal is configured to enable an authenticated user to access, retrieve, and present user-owned content files within the unified collaborative session. In this way, multiple users may simultaneously access, retrieve, and present their own content files on a single computing device.
