Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If real-time layer synthesis is performed with a large quantity of layers, then the layer synthesis result is complete and accurate, but the computing amount is huge causing frame freezing and poor user experience
Solution Approach 1:
The patent segments the layer synthesis process into two distinct phases: a pre-synthesis phase where foreground layers are processed offline to generate intermediate images, and a real-time synthesis phase where only essential layers are combined. This segmentation divides the computationally intensive task into manageable parts, allowing complex foreground layer processing to occur separately from time-critical real-time rendering.
Solution Approach 2:
The patent performs preliminary synthesis of foreground layers before the actual real-time synthesis occurs. By pre-processing foreground layers to create intermediate images that capture essential visual information, the system prepares data in advance so that during real-time operation, less computational work is required, eliminating frame freezing while preserving synthesis quality.
2Manufacturing precision
If all foreground layers participate in real-time synthesis, then the synthesis result maintains high quality, but the quantity of layers increases computational load
Solution Approach 1:
The patent extracts foreground layers from the real-time synthesis pipeline and processes them separately through pre-synthesis. By taking out these computationally demanding layers and handling them in advance, the system reduces the number of layers that must be processed during real-time synthesis, thereby lowering computational complexity while maintaining synthesis quality through the use of generated intermediate images.
Solution Approach 2:
The patent changes the processing parameters of foreground layers by applying pre-synthesis operations that transform them into intermediate images with optimized characteristics. This parameter transformation allows the foreground layer information to be represented in a form that is more efficient for real-time processing, reducing computational requirements while preserving visual fidelity.
3Ease of operation
If layer synthesis is performed in real-time without pre-synthesis, then the processing is simpler, but frame freezing occurs due to high computing demands
Solution Approach 1:
By performing preliminary synthesis of foreground layers before real-time operation, the patent prepares necessary computational data in advance. This preliminary action ensures that during real-time synthesis, the system only needs to perform simpler operations with pre-processed data, maintaining display stability and preventing frame freezing while keeping real-time processing relatively simple.
4Productivity
If the quantity of foreground layers is reduced through pre-synthesis, then real-time synthesis efficiency improves, but the pre-synthesis process adds initial processing time
Solution Approach 1:
The patent performs pre-synthesis operations in advance, before the user needs real-time synthesis. By moving the computationally intensive foreground layer processing to a preliminary phase that occurs before real-time operation, the system accepts initial processing time as a trade-off for achieving high real-time synthesis efficiency during actual use.
Solution Approach 2:
The patent creates intermediate images that serve as copies or representations of the synthesized foreground layer information. These intermediate images capture the essential visual data, allowing the system to work with simplified data structures during real-time operation rather than processing the original complex foreground layers repeatedly.
