Browser Page Restoration via Predetermined File URL Detection

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing page restoring methods for mobile browsers often result in the loss of user browsing information when the browser exits abnormally, as they revert to a default page without preserving the previously accessed URL, making it difficult for users to re-locate and access the original webpage.

Innovation Solution

A method and device that detect whether a predetermined file storing the URL accessed before the browser exit is empty, and if not, restore the corresponding page as the displaying page, including options to prompt the user for confirmation and maintain page state information to accurately restore the previous browsing state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the browser uses a default page restoration method after abnormal exit, then the browser can restart successfully, but the user's browsing information is lost

Engineering Contradiction:

Improvebrowser restart reliabilityVSAvoiduser browsing information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The browser performs preliminary action by recording the URL of the current page before abnormal exit occurs. A predetermined file stores the URL information in advance, so when the browser restarts after abnormal exit, the recorded URL can be automatically restored, preventing loss of user browsing information while ensuring reliable browser restart.

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If the browser stores URL information in a predetermined file, then user browsing information can be restored after abnormal exit, but the device complexity increases

Engineering Contradiction:

Improveuser browsing informationVSAvoidbrowser system complexity

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The invention extracts only the essential URL information from the complex browsing state and stores it separately in a predetermined file. This extraction approach simplifies the restoration process by focusing on the critical data (URL) rather than the entire browsing state, thereby minimizing the increase in system complexity while still enabling effective information restoration.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of manufacture

If the browser restores the default page after abnormal exit, then the restoration process is simple, but the user cannot easily re-locate the original webpage

Engineering Contradiction:

Improverestoration process simplicityVSAvoiduser access to original page

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The browser provides feedback to the user by automatically restoring the previous URL after abnormal exit. The predetermined file contains the recorded URL information, and when the browser restarts, it uses this feedback information to restore the previous page, making it easy for users to re-locate the original webpage without manual intervention.

Inventive Principle:

Principle #23Feedback

AI summary

A page restoring method includes when starting, detecting whether a predetermined file is empty. The predetermined file is configured to store a Uniform/Universal Resource Locator (URL) accessed before a browser exits abnormally. When detecting that the predetermined file is not empty, take a page corresponding to the URL in the predetermined file as a displaying page.
