Synchronous Script Lazy Loading via Virtual Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional asynchronous script lazy loading techniques lead to slow loading times and inefficient memory usage in web applications, particularly on mobile devices, due to the need for asynchronous design and complex callback functions, which complicates development and increases initial loading times.
Innovation Solution
A synchronous script lazy loading system that splits script source code into modules, loads only the required modules into memory when needed, and executes them using virtual functions, allowing for efficient loading and execution without the need for asynchronous operations or complex callback designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If all script modules are loaded into memory at once, then execution speed is improved, but memory usage increases and initial loading time increases
Solution Approach 1:
The patent divides the script source code into multiple separate script modules instead of loading everything at once. Each module can be independently loaded into memory only when needed, reducing initial memory usage while maintaining fast execution speed for actively used modules.
Solution Approach 2:
The patent pre-loads frequently used script modules into memory during initialization or idle periods, so that when the application runs, these modules are already available in memory for immediate execution, improving speed without requiring all modules to be loaded simultaneously.
2Quantity of substance
If script modules are loaded asynchronously, then memory usage is reduced, but loading time increases and development complexity increases
Solution Approach 1:
The patent implements a dynamic script loading mechanism that adapts to runtime conditions. Script modules are loaded synchronously when needed, but the system dynamically manages which modules remain in memory versus being reloaded, balancing memory usage and loading time based on actual usage patterns.
3Quantity of substance
If script modules are loaded asynchronously with callback functions, then memory usage is reduced, but device complexity increases
Solution Approach 1:
The patent introduces a script manager as an intermediary component that handles the complexity of script module loading, caching, and retrieval. This manager provides a simplified interface to developers while managing the underlying synchronous loading and memory management, reducing development complexity.
4Device complexity
If all script files are stored in a single file, then device complexity is reduced, but loading time increases
Solution Approach 1:
The patent segments the monolithic script file into multiple smaller script modules organized by functionality or usage frequency. This segmentation allows the system to load only the necessary modules rather than parsing and loading an entire large file, significantly reducing loading time while maintaining manageable file organization through the script manager.

AI summary
A synchronous script lazy loader generates a plurality of virtual functions. Each one of the plurality of virtual functions corresponds to one of a plurality of script modules. The plurality of script modules may be associated with a script. The synchronous script lazy loader loads each of the plurality of virtual functions into a storage space. The synchronous script lazy loader loads a desired one of the plurality of script modules into a memory from the storage space. The synchronous script lazy loader executes the desired script module from the memory when a corresponding one of the plurality of virtual functions is requested for initial execution.
