Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional webpage loading methods are used, then webpages can display image information, but the loading time length of images cannot be obtained
Solution Approach 1:
The patent applies preliminary action by setting up event tracking mechanisms in advance within the HTML file before image loading occurs. The tracking code is embedded in the webpage structure beforehand, with event listeners configured to capture loading start and end events, ensuring that timing data is automatically recorded without requiring post-processing or additional measurement tools.
Solution Approach 2:
The patent implements feedback by establishing a closed-loop timing system that continuously monitors image loading events. The event tracking mechanism captures loading start timestamps, waits for loading completion events, and automatically calculates the loading duration, providing real-time feedback on image loading performance that can be used for optimization.
2Loss of information
If image proportion in webpage is increased, then information expressiveness is improved, but image service quality requirements increase
Solution Approach 1:
The patent uses feedback by continuously monitoring image loading performance metrics and making the webpage loading process visible and measurable. By tracking loading times and providing data on image service quality, the system enables ongoing optimization of image delivery to maintain high quality standards as image content increases.
Solution Approach 2:
The patent applies parameter changes by measuring and analyzing various loading parameters such as loading start time, loading end time, and loading duration. This data-driven approach allows for optimization of image service quality parameters including loading speed, cache utilization, and delivery efficiency.
3Measurement precision
If event tracking is implemented in HTML file, then loading start time can be obtained, but system complexity increases
Solution Approach 1:
The patent applies self-service by implementing autonomous event tracking within the HTML file that automatically captures loading timestamps without requiring external monitoring tools or complex infrastructure. The tracking mechanism serves itself by using native browser events and automatic timestamp generation, eliminating the need for additional measurement equipment or complex system architecture.
