Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current solutions for developing mobile business applications that operate offline are complex and costly, requiring extensive custom code for handling disconnected operations, data synchronization, and conflict resolution, which is time-consuming and error-prone, especially during prototyping and concept testing.
Innovation Solution
A low-code environment with a UX builder that enables developers to configure data sources, synchronization policies, and conflict resolution options, and an application server that manages synchronization requests, conflict detection, and user interface rendering, reducing the need for custom code and simplifying the development of transactional applications for unreliable wireless networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex custom code is written to handle offline operations and data synchronization, then data integrity and synchronization reliability are improved, but development time and complexity increase significantly
Solution Approach 1:
The patent introduces an intermediary synchronization service that mediates between mobile devices and the central database. This service handles offline operations, conflict detection, and data synchronization automatically, eliminating the need for complex custom code in mobile applications while ensuring data integrity through centralized coordination.
Solution Approach 2:
The synchronization service performs self-service by automatically detecting changes on mobile devices, identifying conflicts with the central database, and coordinating updates without requiring manual intervention or complex error handling code. The system manages its own synchronization state and resolves conflicts autonomously.
2Reliability
If extensive custom code is implemented for conflict resolution and synchronization, then synchronization reliability is improved, but development time increases
Solution Approach 1:
The synchronization service is designed as a universal platform that handles multiple functions: offline data storage, change tracking, conflict detection, and coordination with the central database. This multi-functional service eliminates the need for separate custom implementations in each mobile application, reducing development time while maintaining synchronization reliability.
Solution Approach 2:
The system changes the operational parameters of data synchronization by introducing a centralized service that manages synchronization state, timing, and conflict resolution. This parameter-based approach replaces complex custom logic with configurable synchronization policies, reducing development effort while ensuring reliable operation.
3Adaptability or versatility
If custom per-application synchronization logic is written, then application-specific synchronization needs are met, but development cost increases
Solution Approach 1:
The patent segments the synchronization functionality into a separate centralized service that is independent of individual mobile applications. This segmentation allows each application to use the same synchronization infrastructure without custom code, reducing development costs while maintaining application-specific adaptability through configuration rather than coding.
Solution Approach 2:
The centralized synchronization service acts as an intermediary layer between diverse mobile applications and the central database. This intermediary handles application-specific synchronization needs through standardized interfaces and configurable policies, eliminating the need for custom per-application logic while maintaining adaptability to different use cases.
4Ease of operation
If local database replica is used for offline operation, then offline functionality is improved, but data validation and synchronization complexity increase
Solution Approach 1:
The synchronization service serves as an intermediary that validates data before it reaches the central database. Mobile devices can operate offline with local database replicas without implementing complex validation logic, as the centralized service performs validation and conflict detection automatically during synchronization.
Solution Approach 2:
The system performs self-service validation by having the synchronization service automatically check data integrity, detect conflicts, and coordinate updates with the central database. This eliminates the need for complex validation code in mobile applications while ensuring data quality during offline operation.
