Web Form Autosave for Data Loss Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing web-based information entry systems fail to adequately safeguard against data loss due to factors like power loss, system failure, and user error, especially with the increasing number of web-based interactive applications and inexperienced users.
Innovation Solution
A method and system that provide a forms autosave feature within web browser applications, allowing users to periodically and automatically save forms content, enabling its retrieval and repopulation in case of data loss, with options for configuration and privacy control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If web-based information entry systems are used without autosave functionality, then device complexity and ease of operation are maintained at basic levels, but data loss occurs due to power loss, system failure, or user error
Solution Approach 1:
The system performs preliminary action by automatically saving form content at periodic intervals before any potential failure occurs. The autosave feature continuously monitors form input and stores data in local storage, ensuring that even if power loss or system failure occurs, the data is already preserved. This proactive approach resolves the contradiction by implementing reliability without requiring complex manual backup procedures.
Solution Approach 2:
The autosave functionality provides self-service by automatically managing data preservation without user intervention. The system monitors itself, detects when form content changes, and initiates saving operations autonomously. This eliminates the need for users to manually save data, thereby improving reliability while keeping the user interface simple and not increasing perceived system complexity.
2Reliability
If periodic autosave functionality is implemented, then data loss is reduced, but loss of time occurs during retrieval operations after failure
Solution Approach 1:
By performing save operations continuously in the background before any failure occurs, the system ensures that the most recent data is already stored. When failure occurs, users can immediately retrieve the latest saved content without waiting for post-failure save operations. This preliminary action approach minimizes retrieval time while maintaining high reliability.
Solution Approach 2:
The system creates copies of form content at periodic intervals and stores them in local storage. When failure occurs, users can retrieve these pre-made copies instantly without needing to reconstruct the data. This copying mechanism resolves the contradiction by providing rapid retrieval (reducing time loss) while maintaining data preservation through multiple saved copies.
3Productivity
If autosave feature is added to web browser, then productivity increases by allowing automatic refilling of forms, but device complexity increases
Solution Approach 1:
The autosave feature leverages existing universal components already present in modern web browsers, such as local storage APIs and event listeners. By building on these universal building blocks rather than creating custom proprietary systems, the patent achieves enhanced productivity while minimizing the increase in device complexity. The feature integrates seamlessly with standard browser functionality.
Solution Approach 2:
The system implements self-service automation where the browser automatically detects form input changes, determines when saving is needed, and executes save operations without user intervention. This automation dramatically improves productivity by eliminating manual save operations and form refilling, while the self-service nature keeps the implementation relatively simple by using standard browser capabilities rather than complex custom systems.
Data Source
AI summary
A system may present a document including a form. Forms content may be received into the form. The received forms content may be periodically and automatically saved to reduce the likelihood that received forms content is lost prior to form submission.
