Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional rendering systems are used to handle complex virtual environments, then rendering completeness is maintained, but rendering efficiency deteriorates
Solution Approach 1:
The rendering system segments graphical features into multiple layers based on mobility characteristics. Static features are rendered separately from mobile features, allowing independent optimization of rendering resources for each layer type.
Solution Approach 2:
Different rendering qualities are applied to different layers. Mobile graphical features receive higher quality rendering with full processing resources, while static graphical features receive lower quality rendering with reduced processing resources, optimizing overall system performance.
2Manufacturing precision
If higher rendering quality is applied to all graphical features, then visual fidelity is improved, but resource consumption increases
Solution Approach 1:
The system applies different rendering qualities to different graphical features based on their mobility. Mobile features that require frequent updates receive higher rendering quality, while static features receive lower rendering quality, optimizing the balance between visual fidelity and processing resource consumption.
Solution Approach 2:
Instead of applying full rendering quality to all features, the system applies partial rendering quality to static features and excessive (full) rendering quality only to mobile features that require it, reducing overall resource consumption while maintaining necessary visual quality.
3Use of energy by moving object
If rendering quality is reduced for static features, then resource burden is reduced, but visual fidelity may deteriorate
Solution Approach 1:
The system strategically applies reduced rendering quality only to static graphical features where visual fidelity requirements are lower, while maintaining high rendering quality for mobile features that require frequent updates and have higher visual importance.
Solution Approach 2:
The layer-based rendering system acts as an intermediary that mediates between resource constraints and visual fidelity requirements by routing different graphical features to appropriate rendering quality levels based on their mobility and visual importance characteristics.
