Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing software platforms limit unauthenticated users from accessing applications without an invitation during video conferences, creating friction in the user experience and preventing new users from trying out applications.

Innovation Solution

Implementing an 'instant apps' mode that allows unauthenticated users to access software applications directly from various entry points without requiring authentication or an invitation, using client-side and server-side processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If authentication process is required for application access, then security and user control are improved, but ease of operation and user experience deteriorate

Engineering Contradiction:

Improveauthentication securityVSAvoidapplication access convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The access model is segmented into two distinct modes: authenticated access mode (for full functionality) and unauthenticated access mode (for limited functionality). This allows the system to provide different levels of access based on authentication status, resolving the contradiction by enabling convenient access for unauthenticated users while maintaining security for authenticated users.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different quality levels of access are provided to different user groups. Unauthenticated users receive limited functionality with simplified access, while authenticated users receive full functionality. This local differentiation allows the system to optimize for both ease of operation (for unauthenticated users) and security (for authenticated users).

Inventive Principle:

Principle #3Local quality

2Reliability

If invitation-based access control is implemented, then application security and user control are improved, but ease of operation and user experience deteriorate

Engineering Contradiction:

Improveaccess control securityVSAvoidapplication access convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Access control is segmented into invitation-based mode (requiring explicit invitation) and unauthenticated access mode (no invitation needed). This segmentation allows the system to maintain security through invitations for authenticated users while providing convenient direct access for unauthenticated users, resolving the contradiction between security and ease of operation.

Inventive Principle:

Principle #1Segmentation

3Ease of operation

If unauthenticated access is enabled without limitations, then ease of operation is improved, but application security and reliability deteriorate

Engineering Contradiction:

Improveapplication access convenienceVSAvoidaccess security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

Different quality levels of access are provided based on authentication status. Unauthenticated users receive limited functionality with simplified access (high ease of operation), while authenticated users receive full functionality (high security). This local differentiation resolves the contradiction by optimizing for the appropriate metric for each user group.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system provides partial functionality to unauthenticated users rather than full functionality. This partial action approach allows unauthenticated users to access basic features conveniently while preventing access to sensitive or restricted features, thereby maintaining security without sacrificing ease of operation for the target user group.

Inventive Principle:

Principle #16Partial or excessive action

4Reliability

If authentication process is required before application access, then application security is improved, but loss of time and user experience deteriorate

Engineering Contradiction:

Improveapplication access securityVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Access paths are segmented into authenticated path (requiring authentication) and unauthenticated path (no authentication required). Users can choose the appropriate path based on their needs, reducing the time loss for unauthenticated users who only need basic access while maintaining security for authenticated users.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system introduces an intermediary access mode for unauthenticated users that bypasses the full authentication process. This intermediary path allows users to access applications quickly without undergoing complete authentication, thereby reducing time loss while still maintaining a level of security through the unauthenticated access control mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The invitation-less and unauthenticated access to software applications is enabled at client devices, thereby allowing device users to access and use software applications without initiating an authentication process such as OAuth. A client device of a first device user who is unauthenticated to a software application transmits a request to access the software application within a client application at the client device. The client application then accesses the software application based on the request, based on the first device user being unauthenticated to the software application, and independent of an invitation to access the software application from a second device user who is authenticated to the software application.
