Engineering Contradiction Analysis
1Productivity
If object optimization processes (conversion, combination, division) are performed during rendering, then processing load is reduced and rendering speed is improved, but prediction accuracy deteriorates when these optimizations are not considered in time estimation
Solution Approach 1:
The patent applies preliminary action by performing object optimization processes (conversion, combination, division) during the prediction phase before actual rendering. The prediction unit executes these same optimization steps on the input data to transform objects, then calculates rendering time based on the optimized object characteristics. This ensures the prediction reflects the actual rendering process that will occur, thereby resolving the contradiction between achieving fast rendering through optimization and accurately predicting the time required.
2Manufacturing precision
If the number of objects is increased through detailed interpretation, then rendering completeness is improved, but processing load increases and rendering time extends
Solution Approach 1:
The patent applies merging by combining multiple small objects into larger composite objects during the optimization process. The combination unit groups objects based on spatial proximity and visual similarity, reducing the total object count while preserving the essential visual content. This allows the system to maintain rendering completeness (all visual elements are still represented) while significantly reducing processing load and rendering time.
Solution Approach 2:
The patent applies segmentation by dividing complex rendering tasks into distinct optimization stages: conversion unit transforms object representations, combination unit merges compatible objects, and division unit splits overly complex objects into manageable components. This segmented approach to object optimization allows the system to process detailed data efficiently by handling different aspects of complexity separately, maintaining completeness while managing processing load.
