Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High data traffic across communication links in remote graphics systems burdens computing resources, necessitating a reduction in data transmission to optimize bandwidth usage.
Innovation Solution
A graphics system that segments line primitives into bounding areas or rectangles based on orientation and length, reducing data transmission by using a single bounding area for vertical, horizontal, or short lines, and multiple bounding rectangles for angled lines, thereby optimizing data processing and transmission.

Engineering Contradiction Analysis
1Reliability
If line primitives are transmitted as complete graphical data, then graphics rendering quality is maintained, but data traffic increases burdening computing resources
Solution Approach 1:
The patent segments line primitives into bounding areas based on their orientation and length characteristics. By dividing the graphical data into discrete bounding area units, the system transmits only the necessary information about each segment rather than complete line primitive data, thereby reducing overall data traffic while preserving rendering quality through precise spatial definition of each segment.
Solution Approach 2:
The patent applies different bounding area segmentation strategies based on the local characteristics of each line primitive. Lines with specific orientations (vertical, horizontal, angled) and lengths are handled differently, with more complex angled lines being segmented into multiple bounding areas while simpler lines use single bounding areas. This localized approach optimizes data transmission by applying segmentation only where necessary to maintain rendering quality.
2Manufacturing precision
If complete line primitive data is transmitted, then graphical accuracy is preserved, but bandwidth requirements increase
Solution Approach 1:
The patent extracts only the essential bounding area information from complete line primitive data. By taking out and transmitting only the critical spatial definition data (bounding area coordinates and dimensions) rather than full line primitive specifications, the system maintains graphical accuracy for rendering while significantly reducing bandwidth consumption.
Solution Approach 2:
The patent applies partial segmentation action by creating bounding areas that may be slightly larger than the minimum necessary to encompass line primitives. This partial action approach ensures that all graphical accuracy requirements are met while avoiding the excessive data transmission that would result from using complete line primitive data for every possible rendering scenario.
3Quantity of substance
If line primitives are segmented into multiple bounding areas, then data transmission is reduced, but processing complexity increases
Solution Approach 1:
The patent implements dynamic segmentation logic that adapts the number of bounding areas created based on line primitive characteristics. The processing complexity is dynamic rather than fixed - simple vertical/horizontal lines generate single bounding areas with minimal processing, while angled lines trigger multi-bounding-area segmentation. This dynamic approach reduces average data transmission volume while keeping processing complexity manageable through conditional logic.
Solution Approach 2:
The patent changes the parameter of data representation from complete line primitive specifications to bounding area definitions. By transforming the data structure parameters (from endpoint coordinates and slope to bounding box dimensions and position), the system achieves reduced data transmission volume. The parameter transformation is applied selectively based on line characteristics, balancing transmission efficiency with processing complexity.
