Firearm Barrel Stabilization via Rear-Mounted Servo and Biaxial Bearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm stabilization systems, such as those with built-in servo systems, often compromise the balance and require complex sight mounting or trigger activation methods, leading to reduced accuracy and increased training requirements.
Innovation Solution
A servo system integrated into the firearm that measures barrel rotation speed and adjusts the barrel orientation using motors located at the rear end, with a biaxial bearing allowing horizontal and vertical movement, stabilizing the barrel without altering the weapon's balance or trigger function, and activated by the marksman's aiming position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If motors are mounted in the forward end of the barrel to stabilize aiming direction, then the barrel orientation is stabilized, but the point of gravity moves forward requiring more power to hold the rifle horizontally
Solution Approach 1:
Instead of mounting motors in the forward end of the barrel, the invention inverts the arrangement by mounting the motors at the rear end of the barrel, which stabilizes the aiming direction without moving the point of gravity forward, thus avoiding the drawback of requiring more power to hold the rifle horizontally
2Measurement precision
If the sight is mounted on the barrel surrounded by the pipe to show actual direction of shot, then the sight shows accurate direction, but the design becomes complicated
Solution Approach 1:
The invention extracts the sight from the complex arrangement of being mounted on the barrel surrounded by the pipe, and instead mounts it on the rear sight base, which simplifies the design while maintaining the ability to show the actual direction of shot
3Extent of automation
If the trigger is used to activate the servo system by pulling to a first position, then the servo system is activated, but there is a risk of accidental firing and requires considerable training
Solution Approach 1:
The invention introduces a separate activation switch as an intermediary device to activate the servo system, distinct from the trigger mechanism. This switch is operated by the thumb or forefinger of the right hand, providing a reliable and intuitive activation method that eliminates the risk of accidental firing associated with using the trigger for dual purposes
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances firing accuracy by attenuating unintentional barrel movements, allowing for easier aiming and faster follow-through, applicable to various firearms without altering their balance or requiring additional training.
Implementation Method 1
a biaxial bearing which allows these parts to move horizontally and vertically in relation to each other
Implementation Method 2
a servo system stabilizing the orientation of the barrel built-in in the weapon... measuring means are included continuously measuring the rotation speed vertically and horizontally of the barrel and motors able to change the direction of the barrel
Implementation Method 3
The moment of inertia of the butt end causes a turning torque to act on the barrel the direction of which is then changed

AI summary
A method for stabilizing a weapon, e.g. a rifle or a handgun, barrel movements when aiming by attenuating the influence of, primarily, unintentional barrel movements on the barrel orientation. The method is especially characterized in the steps of - providing a hinge (3) between the barrel front part (1), which comprises the barrel (1), and the weapon rear part (2), which comprises the weapon butt end (2'), for mutual movability between said parts; - continuously detecting the barrel longitudinal direction movement in at least two planes; and - controlling at least one angle between the butt end and the barrel longitudinal direction orientation, respectively, by means of a control system (4h, 4v, 5h, 5v, 6h,6v) so that changes in the barrel orientation are counteracted. The invention also relates to a device and a fire arm.
