Display Device Dynamic Webpage Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with limited memory capacity struggle to smoothly and rapidly display large-capacity webpages due to memory shortages, as existing methods only partially address the issue of resource loading and management.
Innovation Solution
A display device with a user input interface, display unit, network interface, and control unit that receives scroll commands to dynamically adjust the current webpage area and resource loading, deleting unnecessary resources and optimizing memory usage by adjusting the period of resource retrieval based on scroll speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all resources included in the webpage are downloaded simultaneously, then the webpage can be displayed completely, but the memory capacity is exceeded and the webpage is forcibly terminated
Solution Approach 1:
The patent divides the webpage into multiple areas (first webpage area, second webpage area, etc.) and downloads resources for each area separately rather than all at once. The control unit determines whether to download resources for the second webpage area based on whether the first webpage area has been completely displayed, thereby segmenting the resource download process to fit within limited memory capacity.
Solution Approach 2:
The patent performs preliminary downloading of resources for the first webpage area before downloading resources for the second webpage area. This preliminary action ensures that resources are downloaded in a staged manner, allowing the display device to render the first area completely before allocating memory for the second area's resources.
2Quantity of substance
If only resources to be additionally displayed are downloaded dynamically, then the memory usage is reduced, but the time for loading the first page is increased
Solution Approach 1:
The patent performs preliminary downloading of resources for the first webpage area immediately when the webpage URL is input, without waiting for user scrolling actions. This preliminary action reduces the perceived loading time for the initial view while still maintaining memory efficiency by not downloading all resources at once.
Solution Approach 2:
The patent dynamically adjusts the resource download strategy based on user scrolling behavior. When the scrolling operation exceeds a reference threshold, the control unit determines to download resources for the second webpage area, making the download process adaptive to actual user needs rather than static.
3Reliability
If resources are continuously loaded to maintain display quality, then the display performance is improved, but the memory shortage occurs due to continuous loading
Solution Approach 1:
The patent implements a mechanism where resources for the second webpage area are not downloaded until the first webpage area has been completely displayed and its resources are no longer needed in memory. This allows memory to be recovered and reused, preventing memory shortage while maintaining display performance for the currently visible area.
Solution Approach 2:
The patent dynamically controls the resource download process based on real-time display status and scrolling operations. The control unit monitors whether the first webpage area has been completely displayed and adjusts the download of second area resources accordingly, creating a dynamic balance between display quality and memory usage.
