Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current direct fire weapon systems face challenges in consistently hitting targets due to external ballistic factors such as bullet drop, target velocity, range, wind, and temperature, especially when engaging multiple targets or mobile targets like unmanned aerial vehicles, and lack a cost-effective system for coordinating fire from multiple positions.
Innovation Solution
A device and system comprising electromechanical sensors, information transmission systems, and visual displays that can be mounted on various weapons, using Differential Global Navigation Satellite Systems, distance sensors, and atmospheric condition sensors to provide accurate target information and coordinate fire between multiple weapons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional direct fire weapon systems are used without advanced targeting assistance, then the system remains simple and low-cost, but the accuracy and effectiveness of targeting deteriorates due to inability to compensate for ballistic factors
Solution Approach 1:
The patent combines multiple independent systems into a single integrated device: GPS receiver for location, accelerometer for orientation and motion, barometer for altitude, and weapon control system are merged into one unit that automatically processes data and provides targeting assistance. This resolves the contradiction by achieving high measurement precision through sensor fusion while maintaining relatively simple device implementation through integrated architecture.
Solution Approach 2:
The system automatically calculates ballistic compensation, target location, and firing parameters without requiring manual input from the shooter. The device self-calibrates using sensor data, automatically determines weapon orientation via accelerometer, and provides real-time targeting solutions. This automation achieves high accuracy while keeping the interface simple for the end user.
2Productivity
If multiple shooters coordinate fire on multiple targets without a coordination system, then the system remains simple, but the effectiveness of coordinated fire deteriorates due to inability to track and engage multiple moving targets simultaneously
Solution Approach 1:
The device performs multiple functions: it tracks weapon orientation, calculates ballistics, locates targets via GPS, coordinates with other shooters, and provides firing solutions for both stationary and moving targets. This multi-functionality achieves high coordinated fire effectiveness while maintaining a single integrated device rather than requiring separate systems for each function.
Solution Approach 2:
The system continuously receives feedback from accelerometers about weapon motion and orientation, from GPS about location and target position, and from barometers about altitude changes. This real-time feedback enables dynamic adjustment of targeting solutions for moving targets and coordinated fire, achieving high productivity through adaptive control while keeping the feedback loop automated and simple to operate.
3Measurement precision
If shooters engage distant targets without ballistic compensation, then the weapon system remains simple, but the accuracy deteriorates due to uncorrected effects of bullet drop, wind, and atmospheric conditions
Solution Approach 1:
The patent replaces manual ballistic calculation and sight adjustment with an automated electronic system. The accelerometer electronically determines weapon orientation and motion, the GPS electronically calculates position and range, and the processor automatically computes ballistic compensation. This substitution achieves high distance shot accuracy while keeping the device relatively simple by using standard electronic sensors and processors rather than complex mechanical ballistic computers.
