Solution Overview

Problem

Conventional synchronization solutions are limited to two-way connections, lack change tracking, struggle with human error recovery, lack flexibility in role-based administration, and cannot scale for diverse synchronization needs, and are often restricted to a small set of endpoint devices or applications.

Innovation Solution

A hub-and-spoke cloud-based SaaS architecture that allows for multi-point synchronization, includes inbound synchronization with real-time change logging, flexible role-based administration, and scalable synchronization across various endpoints, including mobile devices and cloud services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional two-way synchronization solutions are used, then implementation is simple, but scalability is limited and cannot support multiple endpoints efficiently

Engineering Contradiction:
ImprovescalabilityVSAvoidarchitecture complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system segments the synchronization network into hierarchical levels: endpoint devices are grouped into zones, zones are grouped into regions, and regions are managed by regional synchronization servers. This segmentation allows the system to scale by adding more zones, regions, and servers without requiring complete reconfiguration of the entire network, thus resolving the contradiction between scalability and complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Regional synchronization servers act as intermediaries between endpoint devices and cloud-based synchronization service. These servers handle local synchronization traffic and only communicate with the cloud service when necessary, reducing the complexity of direct cloud-endpoint connections while enabling scalable deployment across multiple regions.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple two-way synchronization partnerships are set up individually, then each connection can be managed separately, but the number of connections increases exponentially with more endpoints

Engineering Contradiction:
Improvemulti-point synchronization capabilityVSAvoidnumber of connections
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple endpoint devices within a zone are merged into a single synchronization unit that connects to the zone synchronization server. This combining approach allows n endpoints to synchronize through a single connection point rather than requiring n*(n-1)/2 individual connections, enabling multi-point synchronization while keeping the connection count linear rather than exponential.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system transitions from a flat peer-to-peer connection model to a hierarchical multi-dimensional structure with endpoints, zones, regions, and cloud services at different levels. This dimensional organization allows endpoints to synchronize with multiple other endpoints indirectly through their zone and region hierarchies, achieving n-way synchronization without n*(n-1) direct connections.

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

3Reliability

If conventional synchronization solutions are used, then setup is straightforward, but change tracking and human error recovery are not available

Engineering Contradiction:
Improveerror recovery capabilityVSAvoidsynchronization management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system implements comprehensive feedback mechanisms including change logs that track all synchronization operations, conflict detection systems that monitor for data inconsistencies, and automatic rollback capabilities that can reverse erroneous changes. These feedback systems provide reliability by detecting and correcting errors while maintaining detailed records for audit and recovery purposes.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by creating backup copies of data before synchronization operations, pre-configuring conflict resolution rules, and establishing recovery procedures in advance. This preliminary preparation enables automatic error recovery without requiring complex real-time decision-making, thus improving reliability while managing complexity through pre-planned procedures.

Inventive Principle:
Principle #10Preliminary action

4Adaptability or versatility

If conventional synchronization solutions are used, then they work with limited endpoint types, but implementing support for diverse devices requires extensive customization

Engineering Contradiction:
Improveendpoint compatibilityVSAvoidimplementation effort
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The system implements a universal synchronization protocol and standardized data models that can work with diverse endpoint types including mobile devices, tablets, desktops, and IoT devices. The zone-based architecture and hierarchical synchronization approach provide a universal framework that adapts to different device types without requiring extensive customization, thus achieving broad endpoint compatibility while maintaining ease of implementation.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A method of synchronizing a plurality of end points is disclosed. A spoke is connected to a hub. The connecting of the spoke to the hub includes performing inbound synchronization of all of a set of data items or a subset of the set of data items with a replica. One or more additional spokes are connected to the hub. The connecting of the one or more additional spokes to the hub includes performing inbound synchronization of all of an additional set of data items or a subset of the additional set of data items with an additional replica. A subset of a set of data items stored in the replica or the additional replica is selected for outbound synchronization with any of a plurality of spokes except a spoke from which the subset of data items originated.
