Energy-Aware Web Page Element Selection for Mobile Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile device technologies consume a large amount of network traffic and power when displaying web page content, affecting subsequent use and incurring additional costs.
Innovation Solution
A web page display method where a server selects and transmits web page elements based on energy consumption information from the terminal device, reducing energy consumption by only sending elements that meet predetermined energy thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the mobile device displays all web page content received from the server, then the user can view complete web page information, but a large amount of network traffic and power is consumed
Solution Approach 1:
The web page content is segmented into multiple web page elements (e.g., images, texts, videos, scripts). Each element is independently analyzed for its energy consumption characteristics. The terminal device selectively receives and displays only those elements whose energy consumption meets the device's energy threshold, thereby reducing overall energy consumption while maintaining essential content completeness.
Solution Approach 2:
Different web page elements are assigned different energy consumption weights based on their resource requirements (e.g., images consume more energy than texts). The system applies local quality control by evaluating each element's energy consumption individually and making selective display decisions at the element level rather than treating the entire web page uniformly, thus optimizing energy usage while preserving important information.
2Loss of information
If the mobile device receives and processes all web page elements, then the web page display is comprehensive, but network traffic consumption increases
Solution Approach 1:
The system extracts and identifies high-energy consumption web page elements (such as large images, videos, and complex scripts) from the complete web page content. Based on the terminal device's energy threshold, these elements are selectively excluded or deferred from loading. This extraction approach allows the system to remove only the necessary high-consumption elements while retaining essential content, thereby reducing network traffic without significantly compromising web page completeness.
3Reliability
If the server transmits all web page content to the terminal device, then the terminal can display complete information, but the terminal device experiences high power consumption and reduced subsequent usability
Solution Approach 1:
The terminal device performs preliminary energy consumption assessment before displaying web page content. It calculates its available energy threshold and communicates this information to the server or uses it locally to filter incoming web page elements. This preliminary action ensures that only energy-efficient elements are processed and displayed, preventing excessive power consumption that would reduce subsequent device usability while maintaining reliable information delivery within energy constraints.

AI summary
In the method, a server not only obtains a first web page request of a first terminal apparatus, but also obtains first energy consumption information of the first terminal apparatus. After determining first web page content corresponding to the first web page request, the server may select, from first web page elements included in the first web page content, a second web page element whose needed energy consumption is not greater than energy consumption indicated by the first energy consumption information, and transmit second web page content including the second web page element to the first terminal apparatus, to enable the first terminal apparatus to display the second web page content.
