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

VSEngineering 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

Engineering Contradiction:
Improvemuzzle stabilityVSAvoidtrajectory accuracy
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improvebarrel harmonics integrityVSAvoidmuzzle orientation stability
Core Design Contradiction:
Manufacturing precisionVSStability of the object's composition

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.

Inventive Principle:
Principle #15Dynamics

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

Engineering Contradiction:
Improvemuzzle position stabilityVSAvoidtrajectory accuracy
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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

Engineering Contradiction:
Improveextension structure complexityVSAvoidpositioning adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #1Segmentation

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.
