Solution Overview

Problem

Users in collaborative file-sharing systems are reluctant to provide candid comments due to attribution concerns and loss of control over their audience, leading to reduced participation in discussions.

Innovation Solution

A content management system that allows users to post both anonymous and attributed comments, with anonymous comments using a generated anonymous user identifier and avatar, and the option to create comment rooms where comments are only visible to invited users, maintaining user privacy and control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard attributed comments are used in collaborative documents, then user accountability and traceability are improved, but user participation and candid feedback decrease due to attribution concerns

Engineering Contradiction:
Improveuser accountabilityVSAvoiduser participation
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent segments the commenting system into two distinct modes: anonymous commenting and standard attributed commenting. This segmentation allows users to choose the appropriate mode based on their needs, thereby maintaining user participation through anonymous comments while preserving accountability options through attributed comments. The system divides the single commenting function into separate pathways that serve different user preferences and scenarios.

Inventive Principle:
Principle #1Segmentation

2Productivity

If anonymous commenting is enabled, then user participation and candid feedback increase, but user accountability and traceability decrease

Engineering Contradiction:
Improveuser participationVSAvoiduser accountability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent implements dynamic commenting where the attribution characteristic can change based on user action. Users can toggle between anonymous and attributed commenting modes, allowing the system to adapt its behavior dynamically. This dynamic approach enables users to switch from anonymous mode (high participation, low accountability) to attributed mode (lower participation barrier, high accountability) as needed, making the system flexible rather than static.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If comments are visible to all document users, then transparency and collaboration are improved, but user control over audience and privacy are lost

Engineering Contradiction:
Improvecollaboration transparencyVSAvoiduser control over audience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies local quality by allowing different visibility characteristics for different comments within the same document. Each comment can be independently configured to be either publicly visible to all document users or privately visible only to the author and selected users. This local differentiation enables users to maintain overall collaboration transparency while exercising precise control over the audience for each individual comment, addressing privacy concerns without sacrificing collaborative openness.

Inventive Principle:
Principle #3Local quality

AI summary

Anonymous comments and comment rooms can improve privacy and facilitate user activity in a collaboration content item system. Some embodiments include a method for anonymous comments that can include receiving a request to add an anonymous comment to a collaboration content item. The method can further include generating an anonymous user identifier for a user associated with the request. The method can further include inserting the anonymous comment in the collaboration content item with a representation of the anonymous user. The representation can include an anonymous avatar generated based on the anonymous user identifier. Some embodiments may include comment rooms for collaboration content items. Multiple users are associated with a comment room. Comments, annotations, or content updates to a collaboration content item performed within a comment room are visible only to the users associated with the comment room.
