Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional synchronization systems are inflexible and inefficient, particularly in multi-master environments with dynamic network topologies and unpredictable connectivity, leading to high server resource burdens and inadequate offline synchronization capabilities.
Innovation Solution
A multi-master synchronization infrastructure using standardized REST-based interfaces enables efficient synchronization across loosely coupled devices, allowing for offline application experiences by caching data locally and minimizing network traffic, with a synchronization layer that handles changes and conflicts independently of data semantics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated master-client synchronization is used, then synchronization reliability is improved, but device complexity and server resource burden increase in dynamic multi-device environments
Solution Approach 1:
The system segments the centralized master-client model into multiple independent master nodes that can each handle synchronization autonomously. Each device becomes a potential master node capable of independent synchronization operations, dividing the server's burden across multiple distributed nodes while maintaining reliability through redundancy.
Solution Approach 2:
The synchronization system implements universal master node capability where any device can function as a master node for different data sets or time periods. This multi-functionality allows the system to dynamically allocate synchronization responsibilities based on connectivity and resource availability, reducing the burden on any single server while maintaining reliable synchronization.
2Ease of manufacture
If static synchronization setup is used, then device configuration is simplified, but adaptability to dynamic network topology and device connectivity deteriorates
Solution Approach 1:
The system transitions from static configuration to dynamic topology discovery where master nodes and client nodes can dynamically assume roles based on current network conditions. Devices automatically discover available master nodes and establish synchronization relationships without pre-configuration, enabling seamless adaptation to changing connectivity while maintaining simple device interfaces.
Solution Approach 2:
The synchronization system implements self-service through automatic topology discovery and dynamic role assignment. Devices autonomously identify available master nodes, establish connections, and manage their own synchronization relationships without requiring manual configuration or centralized coordination, thereby adapting to dynamic networks while keeping device complexity low.
3Measurement precision
If custom synchronization models with extensive metadata tracking are used, then synchronization precision is improved, but system complexity and scalability deteriorate
Solution Approach 1:
The system changes the fundamental parameters of synchronization by using version identifiers and change tokens instead of extensive metadata tracking. Each data set is associated with simple version parameters that enable precise change detection and synchronization without requiring complex metadata structures, thereby maintaining synchronization precision while reducing system complexity.
4Stability of the object's composition
If centralized master node synchronization is used, then data consistency is improved, but offline synchronization capability and system resilience deteriorate
Solution Approach 1:
The system segments the centralized consistency model into distributed consistency zones where each master node maintains data consistency for its assigned data sets independently. This segmentation enables offline synchronization by allowing multiple independent consistency points, so if one master node is unavailable, other nodes continue to maintain consistency for their respective data, thereby improving both data consistency and offline capability.
