Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional sight adjustment methods are used without accounting for environmental and ballistic factors, then the device complexity is reduced, but the shooting accuracy deteriorates
Solution Approach 1:
The system performs preliminary calibration by firing test projectiles and measuring their actual trajectories using radar. This advance measurement allows the system to pre-determine correction values for sight adjustments before actual shooting, accounting for environmental factors and ballistic properties without adding complexity to the shooting process itself
Solution Approach 2:
The patent replaces traditional mechanical sight adjustment methods with an electronic computing system that uses radar measurements and mathematical calculations to determine precise sight corrections. This substitution of mechanical procedures with electronic computation and automated calculation resolves the contradiction by achieving high precision through software-based solutions rather than complex mechanical adjustment mechanisms
2Manufacturing precision
If multiple environmental and ballistic parameters are measured and accounted for, then the shooting accuracy is improved, but the measurement precision requirements increase
Solution Approach 1:
The system employs feedback by continuously measuring the actual projectile trajectory using radar and comparing it with the intended trajectory. The measured deviations are fed back into the calculation system to refine sight adjustment values, creating a closed-loop system that progressively improves accuracy while managing measurement precision requirements through iterative correction
Solution Approach 2:
The patent accounts for multiple parameters including air pressure, air temperature, wind velocity, wind direction, and projectile properties. By systematically measuring and incorporating these various parameters into the trajectory calculation model, the system achieves high shooting accuracy without requiring extremely high precision in any single measurement, as the combined effect of multiple parameters compensates for individual measurement limitations

AI summary
An apparatus for providing information for adjusting a sight of a projectile weapon is provided. The apparatus comprises an input for receiving information regarding measured velocity of a projectile in flight at least at one moment of time. The apparatus comprises an analyzer for determining the velocity and moment of time; an estimator for estimating value for a set of parameters; a calculator for using velocity, moment of time, estimated value and a zero-in angle of the sight to calculate a velocity of the projectile at the moment of time; and a comparator for comparing calculated velocity and measured velocity to determine whether a difference between the calculated and the measured velocity is less than a predetermined value. The apparatus is configured to repeat estimating, calculation of the velocity of the projectile and comparison with another estimated value for the set of parameters to model a trajectory of the projectile.
