Solution Overview

Problem

Conventional mobile software applications require an internet connection to function, limiting user capabilities for data modification, addition, or deletion when offline.

Innovation Solution

An integrated development environment (IDE) application generates programming code to enable an offline mode for mobile applications, allowing local data storage, retrieval, and synchronization upon reconnection, enabling users to perform operations offline and sync changes when connected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If mobile applications require internet connection to function, then data synchronization and cloud storage are ensured, but user capability for data modification, addition, or deletion is limited when offline

Engineering Contradiction:

Improvedata synchronizationVSAvoidoffline operation capability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The application is segmented into online and offline functional modes. The offline mode stores data locally in a database on the mobile device, allowing full operational capability without internet connection. When online, the application synchronizes selected data with the remote server, thus resolving the contradiction between requiring connection for synchronization and needing offline capability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The application performs preliminary actions by storing data locally in the mobile device's database before needing internet access. This local storage enables users to add, modify, or delete data offline. The synchronization with the remote server is then performed as a subsequent action when connectivity is available, eliminating the limitation of requiring constant internet connection.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If offline mode with local storage is implemented, then user capability for data modification is improved, but device complexity increases

Engineering Contradiction:

Improveoffline operation capabilityVSAvoidlocal storage implementation

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A local database acts as an intermediary between the application and the remote server. This database layer handles all data storage, retrieval, modification, and deletion operations locally, abstracting the complexity of offline/online synchronization from the core application logic. The database serves as a buffer that simplifies the implementation of offline capabilities while maintaining data consistency.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Some embodiments provide a non-transitory machine-readable medium that stores a program. The program receives, from a client device, a project for an existing application. The program further receives from the client device a request to add an offline mode to the existing application. In response to receiving the request, the program also includes programming code in the project for implementing the offline mode in the existing application. The program further generates an application configured for execution on the client device. The application is a version of the existing application that includes the feature for operating the existing application in the offline mode.
