Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If virtual shooting training simulation uses simplified assumptions about bullet motion (center of mass translational motion only), then equipment and shooting places are not required and training can be conducted without restrictions, but the ballistic trajectory and point of impact differ from actual shooting training
Solution Approach 1:
The patent changes the physical parameters of the simulation by incorporating complex bullet motion models that account for rotation, aerodynamic forces, and environmental factors. The system calculates ballistic trajectories using parameters such as bullet spin rate, air density, wind speed, and temperature, transforming the simulation from a simple translational motion model to a comprehensive physics-based model that replicates real-world ballistics.
2Device complexity
If virtual shooting training simulation assumes bullet is not affected by various laws of motion and environment, then the simulation is computationally simple, but the point of impact does not match actual shooting training
Solution Approach 1:
The patent implements dynamic simulation by making the bullet motion model responsive to changing environmental conditions. The system continuously adjusts ballistic calculations based on real-time parameters such as wind speed and direction, air temperature, humidity, and bullet rotation rate. This dynamic approach allows the simulation to adapt to varying conditions, producing reliable point of impact predictions that match actual shooting scenarios.
3Productivity
If virtual shooting training simulation uses simple translational motion model, then training can be conducted frequently without bullet shell management, but the training result is not reflected in actual battle
Solution Approach 1:
The patent replaces the simple mechanical translational motion model with a comprehensive ballistics calculation system that incorporates aerodynamic forces, rotational dynamics, and environmental interactions. The system uses computational physics to calculate bullet trajectory, accounting for drag, lift, Coriolis effect, and other forces that act on the bullet during flight, thereby achieving high point of impact accuracy while maintaining the advantages of virtual simulation.
