Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm trajectory correction systems fail to accurately measure and integrate various variables such as ballistic coefficients, wind data, and inclinometer readings, leading to imprecise projectile impact predictions, especially at long distances, and lack comprehensive software for real-time data integration and correction.
Innovation Solution
An integrated system with sensors and software that measures muzzle velocity, time-of-flight, wind speed, and rifle tilt, using a tubular component with internal sensors, a time-of-flight meter, anemometers, and inclinometers, along with proprietary software to calculate and correct the projectile's trajectory by integrating data from meteorological sources and storing it for subsequent shots.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are integrated to measure various trajectory variables (muzzle velocity, time-of-flight, wind speed, tilt), then measurement precision and trajectory prediction accuracy are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple measurement functions (muzzle velocity sensing, time-of-flight measurement, wind speed detection, and tilt measurement) into a single integrated instrumenting system attached to the firearm. This merging of previously separate measurement devices reduces overall system complexity while maintaining high measurement precision for trajectory prediction.
Solution Approach 2:
The instrumenting system is designed as a multi-functional device that simultaneously performs multiple measurement tasks: measuring muzzle velocity of the projectile, recording time-of-flight, detecting wind speed and direction, and monitoring rifle tilt angles. This universal system replaces multiple separate devices, improving measurement precision without proportionally increasing complexity.
2Measurement precision
If comprehensive data integration and real-time ballistic calculations are implemented, then trajectory correction accuracy is improved, but device complexity and software requirements increase
Solution Approach 1:
The system incorporates a ballistic database pre-loaded with trajectory data for various ammunition types and environmental conditions. Before firing, the user selects the appropriate ammunition type, and the system pre-loads the corresponding ballistic coefficients and trajectory parameters. This preliminary preparation enables real-time accurate calculations without requiring complex computational algorithms during the shooting moment.
Solution Approach 2:
The system measures actual trajectory variables (muzzle velocity, time-of-flight, wind, tilt) and uses this feedback to calculate and display corrected aim points. The feedback loop continuously compares predicted trajectory with actual measurements, allowing real-time trajectory correction while managing software complexity through iterative refinement rather than complex predictive modeling.
3Measurement precision
If sensors are placed close to the muzzle for accurate velocity measurement, then measurement precision is improved, but the system becomes more sensitive to interference and harder to install
Solution Approach 1:
The sensor assembly is nested within a tubular housing that attaches to the firearm's muzzle or barrel extension. This nested structure protects the sensitive velocity sensors from environmental interference while maintaining their close proximity to the muzzle for accurate measurement. The housing also provides a standardized mounting interface, simplifying installation.
Solution Approach 2:
The tubular housing acts as an intermediary structure between the firearm barrel and the sensitive sensors. It provides mechanical support, environmental protection, and signal shielding for the velocity sensors, enabling them to operate close to the muzzle without direct exposure to interfering factors such as muzzle flash, shock waves, and environmental contaminants.
