Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If VRS function is activated manually with code changes, then power consumption is reduced and bandwidth is saved, but developer effort increases and rendering correctness may be compromised
Solution Approach 1:
The system automatically classifies rendering commands and activates VRS without developer intervention. The rendering classifier autonomously analyzes graphic commands, determines rendering types, and controls VRS activation, eliminating the need for developers to manually add API calls or understand VRS nuances.
Solution Approach 2:
A rendering classifier is introduced as an intermediary component between the application and the VRS hardware. This classifier intercepts graphic commands, analyzes rendering properties, and makes intelligent decisions about VRS activation, bridging the gap between application requirements and hardware capabilities without requiring code changes in the application.
2Productivity
If VRS function is activated manually, then GPU computing efficiency is improved, but rendering correctness may be compromised due to trial and error
Solution Approach 1:
The system incorporates feedback mechanisms where the rendering classifier continuously monitors rendering commands and their outcomes. By analyzing rendering properties and comparing expected versus actual results, the system adjusts VRS activation decisions to maintain rendering correctness while optimizing GPU efficiency.
Solution Approach 2:
The rendering classifier performs preliminary analysis of graphic commands before rendering execution. By classifying rendering types in advance and pre-determining appropriate VRS settings, the system ensures rendering correctness from the outset rather than requiring trial-and-error adjustments after rendering issues occur.
3Loss of energy
If VRS is activated without automatic control, then power savings are achieved, but code complexity increases due to API calls
Solution Approach 1:
The complexity of VRS control logic is extracted from the application code and relocated to a dedicated rendering classifier component. This separation allows the application to remain simple while the classifier handles all VRS-related decisions, maintaining power savings without increasing application code complexity.
Solution Approach 2:
The rendering classifier serves multiple functions: it classifies rendering commands, determines rendering types, controls VRS activation, and optimizes power consumption. By consolidating these diverse functions into a single multi-functional component, the system achieves power savings without distributing complexity across multiple code locations.
