Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional barrel brakes for recoil guns face issues with asymmetrical forces and vibrations due to manufacturing tolerances, leading to precision problems and increased space requirements, as they often generate varying braking forces and require additional space for operation.
Innovation Solution
A barrel brake design featuring a hollow cylinder with a control rod and piston rod, filled with brake fluid, where the control rod has varying diameters to control braking forces, ensuring consistent initial braking and reducing space requirements by allowing the braking force to start at the beginning of the braking distance, with a control gap for fluid flow to generate braking forces and a cradle connection for the barrel weapon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the braking cross-section is kept very large at the beginning of the recoil path to minimize braking force, then the braking force is very small, but the braking force cannot start acting from the very beginning of the braking movement
Solution Approach 1:
The control rod is divided into multiple sections with different diameters (first section with constant diameter, second section with varying diameter). This segmentation allows the braking system to provide different braking forces at different stages of the recoil movement, enabling immediate braking action while maintaining controllability throughout the braking process.
2Device complexity
If conventional pipe brakes are used with standard control rods, then the structure is simpler, but manufacturing tolerances cause asymmetrical forces and vibrations
Solution Approach 1:
Different sections of the control rod have different diameters tailored to specific functional requirements. The first section has a constant diameter optimized for initial braking symmetry, while the second section has varying diameter for controlled braking force modulation. This local differentiation ensures manufacturing precision and symmetry where most critical.
3Ease of operation
If additional space is provided for brake operation (as in prior art solutions), then the piston rod can move freely, but the overall space requirement increases
Solution Approach 1:
The control rod is nested inside the piston rod, with both components moving coaxially within the cylinder. This nested arrangement eliminates the need for additional radial space, allowing the piston rod to move freely while maintaining a compact overall brake assembly volume.
4Adaptability or versatility
If the control rod has varying diameters along its length, then the braking force can be controlled during the braking movement, but the manufacturing complexity increases
Solution Approach 1:
The control rod is designed with distinct segmented sections (constant diameter section, varying diameter section) that can be manufactured using standard machining processes. Each section serves a specific functional purpose, making the varying diameter configuration achievable through conventional manufacturing methods without excessive complexity.
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
This design provides consistent and controllable braking forces without increasing space or manufacturing complexity, reducing vibrations and maintaining precision by ensuring symmetrical braking forces across multiple barrel brakes.
Implementation Method 1
the brake fluid displaced by the piston rod must flow through this control gap to equalize the brake fluid volume. The control gap is designed such that the flow of brake fluid through it generates a braking force on the piston rod's movement.
Implementation Method 2
The interior of the cylinder is filled with a brake fluid. When the piston rod moves, the brake fluid displaced by the piston rod must flow through this control gap to equalize the brake fluid volume.

AI summary
The invention relates to a muzzle brake for braking the barrel during the recoil of a barreled weapon, comprising a hollow cylinder, a control rod (2) which is arranged in the cylinder, and a piston rod (3) which surrounds the control rod. The piston rod can be moved coaxially to the cylinder and the control rod, and the interior of the cylinder is filled with a braking fluid (11). In the course of the braking path, the control rod first has a constant diameter which is as large as the munition requires in order to exit the barrel of the barreled weapon. A control profiled section is then provided in which the control rod can have a different diameter.
