Motorized Bipod Extension for Barrel Harmonic Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bipod and tripod gun supports interfere with barrel harmonics and mechanically amplify muzzle misalignments, leading to inaccuracies in projectile trajectory and aiming.
Innovation Solution
A telescopic extension system for gun supports that maintains barrel harmonics by attaching the bipod or tripod further back, allowing for adjustable horizontal and rotational positioning of the support relative to the gun, using actuators and motors for precise adjustments without mechanical interference.
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 position is stabilized, but the barrel harmonics are interfered with causing irregularities in projectile trajectory
Solution Approach 1:
A telescopic extension assembly acts as an intermediary between the bipod and the gun barrel. The bipod is attached to the extension assembly rather than directly to the barrel, allowing the barrel harmonics to remain unaffected while still providing muzzle stabilization through the extension structure.
2Reliability
If the bipod is mounted further back on the gun stock, then the barrel harmonics are not affected, but the lever arm between attachment point and muzzle causes mechanically amplified displacement of muzzle orientation
Solution Approach 1:
The telescopic extension assembly adds a longitudinal dimension to the support structure, extending the support point forward from the stock toward the muzzle. This dimensional extension reduces the lever arm effect by positioning the support closer to the muzzle while still mounting it on the stock rather than directly on the barrel.
3Measurement precision
If the bipod support position is adjusted between shots, then accuracy and consistency can be maintained, but the adjustment process requires significant movement and time
Solution Approach 1:
The telescopic extension assembly incorporates movable sections that can be adjusted between shots. The first and second telescopic portions can be extended or retracted relative to each other, allowing dynamic adjustment of the support position while maintaining a compact form factor when not in use.

AI summary
An extension system for a gun support, the gun having a barrel with an effective muzzle. The extension system includes a motorized telescopic assembly having a first telescopic portion and a second telescopic portion nested therein. A gun support is removably coupled to a distal end of the second telescopic portion. An actuator that is configured to selectively adjust a horizontal displacement of the second telescopic portion relative to the first telescopic portion is disposed within the first telescopic portion. When the actuator is activated, a piston may be extended which drives the second telescopic portion away from within the first telescopic portion. The extension system may be selectively coupled to the gun or incorporated into a chassis of the gun itself. A distal end of the telescopic assembly comprises means for rotational adjustment relative the proximal end of the assembly.
