Web Page Content Loading Control via Background Cache Updates

Solution Overview

Problem

Existing web page loading technologies face issues with slow loading speeds and delayed updates due to reliance on local caching, which can result in users experiencing slow internet surfing experiences and delayed access to updated content.

Innovation Solution

A method and device for web page content loading that involves receiving a web page access request, reading pre-stored content locally for fast loading, obtaining and caching updated content from a server in the background, and updating the loaded content at an appropriate timing, ensuring timely updates without affecting user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If web page content is read directly from local cache, then loading speed is improved, but content timeliness deteriorates

Engineering Contradiction:

Improveweb page loading speedVSAvoidcontent update timeliness

Core Design Contradiction:

SpeedVSLoss of information

Solution Approach 1:

The patent pre-loads web page content into local cache before the user actually requests it. When a user accesses a web page, the browser checks if the content is already cached and loads it immediately, providing fast loading speed. Meanwhile, the system periodically updates the cache in the background to ensure content timeliness, resolving the contradiction between fast loading and updated content.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements periodic background updates of cached web page content. The browser automatically refreshes the cache at scheduled intervals without requiring user intervention, ensuring that cached content remains up-to-date while maintaining fast loading speeds during user access.

Inventive Principle:

Principle #19Periodic action

2Loss of information

If web page content is obtained from server each time, then content timeliness is improved, but loading speed deteriorates

Engineering Contradiction:

Improvecontent update timelinessVSAvoidweb page loading speed

Core Design Contradiction:

Loss of informationVSSpeed

Solution Approach 1:

The patent pre-loads web page content into local cache before the user actually requests it. When a user accesses a web page, the browser checks if the content is already cached and loads it immediately, providing fast loading speed. Meanwhile, the system periodically updates the cache in the background to ensure content timeliness, resolving the contradiction between fast loading and updated content.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent creates local copies of web page content and stores them in the browser cache. Instead of retrieving content from the server every time, the browser uses these local copies for immediate display, dramatically improving loading speed while periodic updates ensure the copies remain current.

Inventive Principle:

Principle #26Copying

3Ease of operation

If manual refresh is required to update content, then user control is improved, but user experience deteriorates

Engineering Contradiction:

Improveuser controlVSAvoidtime to access updated content

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent enables the browser to automatically refresh and update web page content in the background without requiring user intervention. The system self-manages the cache update process, periodically fetching updated content from the server and replacing cached versions automatically, saving user time while maintaining control through automatic operation.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent implements periodic background updates of cached web page content. The browser automatically refreshes the cache at scheduled intervals without requiring user intervention, ensuring that cached content remains up-to-date while maintaining fast loading speeds during user access.

Inventive Principle:

Principle #19Periodic action
