Engineering Contradiction Analysis
1Reliability
If the Navier-Stokes equation is used to simulate fluid flow, then the fluid simulation accuracy is improved, but the computational complexity and calculation time increase significantly
Solution Approach 1:
The patent extracts only the essential velocity field information from the complex Navier-Stokes equation system. Instead of solving the complete Navier-Stokes equations, the invention uses pre-computed velocity fields from noise images and radial spreading patterns to achieve fluid simulation effects, thereby removing unnecessary computational complexity while maintaining visual accuracy
Solution Approach 2:
The patent creates a simplified copy of the fluid simulation process. Rather than directly solving the Navier-Stokes equations, the system uses velocity fields derived from noise images and radial patterns as substitutes, creating a computational shortcut that reproduces fluid flow visual effects without the full mathematical complexity
2Reliability
If the Navier-Stokes equation is solved for each frame, then the fluid flow visualization accuracy is improved, but the processing time increases
Solution Approach 1:
The patent performs preliminary actions by pre-computing velocity fields from noise images and radial spreading patterns before the actual fluid simulation display. These pre-computed velocity fields are then applied to subsequent frames, eliminating the need to solve the full Navier-Stokes equations in real-time and significantly reducing processing time per frame
Solution Approach 2:
The patent uses simplified, easily computable velocity field representations (derived from noise images and radial patterns) instead of expensive, complex Navier-Stokes solutions. These simplified velocity fields are sufficient for visual purposes and can be computed quickly, acting as disposable approximations that maintain accuracy without the time cost of full physical simulations
3Manufacturing precision
If a large number of calculations are performed to solve the Navier-Stokes equation, then the fluid simulation precision is improved, but the computational efficiency deteriorates
Solution Approach 1:
The patent extracts only the necessary velocity information from the fluid simulation problem. By using noise images and radial spreading patterns to generate velocity fields, the system obtains sufficient precision for visual simulation without performing the extensive calculations required by the full Navier-Stokes equation system
Solution Approach 2:
The patent changes the parameters used for velocity field generation from the complex Navier-Stokes mathematical model to simpler noise-based parameters and radial patterns. This parameter substitution maintains the visual precision of fluid simulation while dramatically improving computational efficiency through simpler, faster-to-compute parameters
