Telescopic Gun Support Extension for Barrel Harmonic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun supports, such as bipods and tripods, either interfere with the harmonics of the barrel during firing or lead to mechanically amplified misalignments and biological-induced aiming errors, affecting the accuracy of the rifle system.
Innovation Solution
A telescopic extension system for gun supports that includes a fore-end attached to the gun, a telescopic assembly with adjustable length, and toggle clamps to position the support near or in front of the muzzle, minimizing interference with barrel harmonics and stabilizing the muzzle against biological and unintended movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bipod is directly attached to the barrel of the gun, then the muzzle is stabilized, but the harmonics of the barrel are materially affected causing irregularities in the projectile's trajectory
Solution Approach 1:
The bipod support is extracted from direct attachment to the barrel and relocated to attach to the gun stock instead. This separation removes the harmful interaction between the bipod and barrel harmonics while maintaining the stabilizing function at the stock level.
Solution Approach 2:
The gun stock serves as an intermediary element between the bipod and the barrel system. By attaching the bipod to the stock rather than directly to the barrel, the stock mediates the support function without transmitting disruptive forces to the barrel harmonics.
2Manufacturing precision
If the bipod is mounted further back on the gun stock, then the barrel harmonics are not affected, but the lever arm between the bipod attachment point and the muzzle causes mechanically amplified displacement of the muzzle orientation
Solution Approach 1:
The extension tube provides dynamic adjustability of the bipod's position along the stock. The shooter can adjust the extension tube length to optimize the lever arm effect, allowing the system to adapt between maximizing stability and minimizing mechanical amplification of movements.
3Stability of the object's composition
If the bipod is positioned to minimize lever arm effects, then muzzle orientation stability improves, but the attachment mechanism interferes with barrel harmonics during firing
Solution Approach 1:
The bipod attachment is extracted from the barrel area and relocated to the gun stock, eliminating direct interference with barrel harmonics while maintaining muzzle position stability through the extended support structure.
4Device complexity
If a fixed-length extension is used, then the structure is simple, but it cannot be adjusted to optimize positioning for different shooting scenarios and gun configurations
Solution Approach 1:
The extension tube incorporates adjustable length capability through telescoping sections with locking mechanisms. This dynamic adjustment feature allows the bipod position to be optimized for different shooting scenarios, gun types, and shooter preferences while maintaining reasonable structural complexity.
Solution Approach 2:
The extension tube is divided into multiple telescoping sections that can be independently adjusted and locked at different lengths. This segmentation provides versatile positioning options while keeping each individual section structurally simple and manageable.

AI summary
An extension system (80) is disclosed for a gun support (12) attached to a gun having a barrel (74) with an effective muzzle (76). The extension system includes: a fore-end (78) attached to the gun adjacent to the barrel; a telescopic assembly having a proximal end and a distal end, the proximal end telescopically coupled to the fore-end (78), the distal end coupled to the gun support (12), where the telescopic assembly includes one or more telescopic portions (88,90); one or more clamps (98) to selectively fix the first telescopic portions (88) to the fore-end (78) to provide an adjustable length of the telescopic assembly, which is then capable of positioning the gun support (12) at or ahead of the effective muzzle (76) and adjacent to the barrel (74) as provided by the fore-end.
