Solution Overview

Problem

Existing enterprise web applications and event management systems like Microsoft Outlook and Nasdaq's IR Insight often require separate event configurations, leading to inefficiencies and inaccuracies in event organization and synchronization.

Innovation Solution

Integrate event management applications with enterprise web applications using a unique identifier (CMS ID) to synchronize event information without duplication, ensuring secure display of web application events only to authorized users.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate event configurations are used in enterprise web applications and event management systems, then each application can maintain its own event management independence, but data duplication and synchronization inefficiencies occur

Engineering Contradiction:

Improveevent management independenceVSAvoiddata duplication

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent merges event management functionality across enterprise web applications and event management systems by implementing a unified event configuration system. Event information is centralized and shared across applications through integration interfaces, eliminating separate event configurations while maintaining functional independence through modular architecture.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal event management system where a single event configuration can be accessed and utilized by multiple enterprise web applications and event management systems. The unified system provides multi-functional capabilities, allowing the same event data to serve different application contexts without duplication.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If event information is synchronized between multiple applications, then integrated event views are achieved, but data duplication and storage overhead increase

Engineering Contradiction:

Improveintegrated event viewVSAvoiddata storage volume

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The patent implements a reference-based copying mechanism where event information is not physically duplicated across applications but accessed through shared references. The unified system maintains a single source of truth for event data, with applications accessing events through standardized interfaces, thereby providing integrated views without proportional increases in data storage.

Inventive Principle:

Principle #26Copying

3Loss of information

If comprehensive event synchronization is implemented across all applications, then complete event information is available to all users, but security risks and unauthorized access may increase

Engineering Contradiction:

Improveevent information completenessVSAvoidsecurity risk

Core Design Contradiction:

Loss of informationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a unified event management system as an intermediary layer between multiple applications and users. This mediator implements centralized security controls, authentication mechanisms, and authorization policies that manage event information distribution. The intermediary ensures complete event information availability to authorized users while preventing unauthorized access through standardized security protocols.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Device complexity

If separate event management systems are used, then system complexity is reduced for each individual application, but synchronization accuracy and event coordination deteriorate

Engineering Contradiction:

Improveindividual application complexityVSAvoidsynchronization accuracy

Core Design Contradiction:

Device complexityVSManufacturing precision

Solution Approach 1:

The patent segments the event management system into a centralized unified management component and distributed application components. Each application maintains simple local event handling logic while the unified system manages synchronization, coordination, and data consistency. This segmentation allows individual applications to remain simple while achieving high synchronization accuracy through the centralized coordinator.

Inventive Principle:

Principle #1Segmentation

AI summary

The described technology relates to integrating events electronically scheduled in enterprise web applications and other event management applications. An improved capability is provided for an event management application like, for example, Microsoft's Outlook™ to provide the user with additional useful information and/or resources associated with scheduled events such as, but not limited to, meetings. Improved capabilities are provided to the enterprise web application clients based upon integration with event applications such as Outlook. Embodiments use a unique identifier generated for an event scheduled in one application for associating corresponding event information in the second application, such that the scheduled event calendars in the first and second applications can be synchronized without duplicating the event information between the two applications.
