Firearm Aiming Accuracy via Shooter Shake Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm systems fail to compensate for shooter-induced shakings and sways, which significantly affect accuracy during shooting.
Innovation Solution
A system comprising a camera or accelerometer/inertia sensor connected to a processing unit that determines the movement of the aim point relative to the target, predicts future movement, and triggers the firearm only when the aim point is within a tolerance of the target point, thereby compensating for shooter instability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional sighting systems (telescopic sight, iron sights, laser sights) are used to improve aiming accuracy, then the shooter can establish a point of aim, but the system cannot compensate for shooter-induced shakings and sways during firing
Solution Approach 1:
The system continuously monitors the position of the aim point relative to the target using a camera or sensor, and uses this feedback to determine when the aim point is within a tolerance zone of the target. This closed-loop feedback mechanism compensates for shooter-induced movements by providing real-time positional information to the firing control system.
Solution Approach 2:
The patent replaces traditional mechanical sighting systems with an electronic/optical system comprising a camera or sensor, processing means, and automated firing control. This substitution enables digital measurement and automated decision-making, allowing the system to compensate for human instability through electronic rather than mechanical means.
2Reliability
If the shooter manually controls the trigger to steady press instead of slap to improve accuracy, then shot placement improves, but the shooter cannot compensate for involuntary shakings and sways
Solution Approach 1:
The system performs the function of steady aiming and timing the firing moment automatically. The camera/sensor continuously tracks the aim point position, the processing means determines when the aim point is within the tolerance zone, and the firing command is issued automatically. This self-service approach relieves the shooter of the burden of manual timing and positioning control.
Solution Approach 2:
The system accelerates the detection and decision-making process by continuously monitoring aim point position and rapidly processing this information to determine the optimal firing moment. This accelerated information processing enables the system to respond quickly to changes in aim point position caused by shooter movements.
3Measurement precision
If environmental factors (air density, cant, tilt) are compensated using BORS system to improve elevation calculations, then long-range accuracy improves, but shooter-induced shakings and sways remain uncompensated
Solution Approach 1:
The system serves multiple functions: it monitors aim point position, determines when the aim point is within the tolerance zone, and controls the firing timing. This multi-functional approach allows the same system to address both environmental compensation (when integrated with BORS) and shooter-induced movement compensation, enhancing the system's adaptability.
Solution Approach 2:
The patent adds a temporal dimension to the aiming process by continuously monitoring the aim point position over time and determining the optimal firing moment. This time-based approach complements the spatial compensation provided by BORS, adding another dimension of accuracy enhancement.

AI summary
The present invention relates to an arrangement and methods for firing a fire arm. The fire arm comprises determining means for determining a movement of an aim point for the fire arm relative to a target. The fire arm also comprises processing means configured to determine a target point for the aim point based on the movement of the aim point relative to the target and to predict the future movement of the aim point. Firing means in the fire arm is configured to fire the fire arm when the aim point is predicted to be within a tolerance of the target point. Thereby the arrangement according to the present invention can increase the accuracy of the fire arm by compensate for shakings and/ or sways from the shooter.
