Solution Overview

Problem

Existing document collaboration systems require time-consuming software installs, tedious session coordination, and steep learning curves, making it difficult to manage multiple users with different privileges and creating collaboration silos that hinder effective information sharing.

Innovation Solution

A system that generates links for annotations in documents, centralizing collaborative context, collaborators, and activities into a unified hub, allowing flexible accessibility and maintaining context with continuous updates, and enabling users to access and interact with annotations directly through web browsers without account registration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If existing document collaboration systems are used, then document sharing capability is provided, but software installation and account setup time increases

Engineering Contradiction:
Improveease of accessVSAvoidsetup time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The patent extracts the core annotation sharing functionality from complex collaboration software suites, delivering only the essential feature via simple links. Users receive annotation links that work independently without requiring installation of comprehensive document management systems, thereby reducing setup time while maintaining the core document sharing capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system creates lightweight copies of annotations in the form of shareable links that can be distributed without the original document or software environment. These link copies encapsulate the annotation data and document reference, allowing users to access annotated content without installing the full collaboration platform

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If existing document collaboration systems are used, then multiple users can access documents, but session coordination complexity increases

Engineering Contradiction:
Improveuser accessibilityVSAvoidsession coordination
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the collaboration experience into independent, self-contained annotation links that can be accessed individually. Each link represents a discrete unit of collaborative work that can be shared and accessed without coordinating complex user sessions, thereby maintaining multi-user accessibility while eliminating session management overhead

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system introduces annotation links as intermediaries between users and documents. These links serve as simple mediators that bridge users to specific annotations without requiring direct connection to the document management system or coordination of user sessions, simplifying the interaction model while maintaining versatility

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If existing document collaboration systems are used, then document editing capability is provided, but learning curve increases

Engineering Contradiction:
Improvecollaboration efficiencyVSAvoidlearning curve
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent employs simple, disposable annotation links that require no training to use. These links are designed to be used immediately upon receipt, eliminating the need for users to learn complex collaboration software interfaces. The links perform their function of sharing and accessing annotations without requiring users to invest time in learning curve-associated features

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

4Adaptability or versatility

If existing document collaboration systems are used, then user privilege management is provided, but system complexity increases

Engineering Contradiction:
Improveprivilege managementVSAvoidsystem architecture
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies local quality by embedding access control directly within each annotation link rather than relying on centralized user management systems. Each link can be configured with specific access permissions (view-only, edit, share) that are inherent to that particular link, allowing flexible privilege management without requiring complex system-wide authentication and authorization infrastructure

Inventive Principle:
Principle #3Local quality

AI summary

Described herein is an annotation system for documents. A computer system includes one or more memories and one or more processors communicatively coupled to the one or more memories. The one or more processors configured to, individually or collectively, add an annotation to a document, generate an identifier for the annotation, encode the identifier in a link, receive an indication that the link was activated, and in response to determining that the indication comprises the encoded identifier, present the document with the annotation selected.
