Solution Overview

Problem

Existing bipod and tripod gun supports interfere with barrel harmonics during firing, affecting projectile trajectory, and mechanically amplify muzzle misalignments due to biological inputs or unintended movements, compromising shooting accuracy.

Innovation Solution

A telescopic extension system for gun supports that maintains barrel harmonics by attaching the support further back, allowing for adjustable horizontal displacement and rotational adjustment of the bipod relative to the gun, minimizing mechanical and biological misalignments.

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 bipod provides stability support, but the harmonics of the barrel during firing are materially affected, altering projectile trajectory

Engineering Contradiction:
Improvebipod stability supportVSAvoidprojectile trajectory accuracy
Core Design Contradiction:
Stability of the object's compositionVSManufacturing precision

Solution Approach 1:

The extension system divides the support structure into separate segments: the bipod remains attached to the stock while a telescopic extension tube is inserted between the barrel and muzzle. This segmentation allows the bipod to provide stability without direct barrel attachment, preserving barrel harmonics and projectile trajectory accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The telescopic extension tube acts as an intermediary element that couples the bipod support to the muzzle without creating direct rigid attachment to the barrel. This intermediary structure transmits support forces while allowing the barrel to maintain its natural harmonic vibrations during firing.

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 attachment point and muzzle mechanically amplifies muzzle displacement

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

Solution Approach 1:

The invention transitions from a two-dimensional problem (bipod position along the gun axis) to a three-dimensional solution by adding a telescopic extension tube that projects forward from the stock-mounted bipod. This allows the support point to be positioned backward on the stock while the extension reaches forward to stabilize the muzzle area, effectively adding spatial depth to the support geometry.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Manufacturing precision

If the extension system adjusts the bipod position, then accuracy and consistency are maintained, but the device complexity increases with telescopic assembly and actuator mechanisms

Engineering Contradiction:
Improveshooting accuracy and consistencyVSAvoidtelescopic assembly structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The extension system employs dynamic adjustment capabilities through a telescopic assembly with an actuator that can modify the extension tube length. This dynamic structure allows the bipod position to be optimized for different shooting scenarios while maintaining accuracy, transforming a static support system into an adaptable one that responds to varying operational requirements.

Inventive Principle:
Principle #15Dynamics

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.
