Axially Offset Foregrip Aligns Support Arm
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foregrips on long guns, such as carbine type rifles, are not ergonomically correct, causing stress and discomfort to users, leading to potential injury and suboptimal handling of the rifle due to misalignment of the support arm with the barrel.
Innovation Solution
An axially offset foregrip assembly that couples to the fore-end of a long gun, allowing the grip axis to be horizontally offset from the barrel's longitudinal axis, providing a more aligned and comfortable grip position for the user's hand, thereby improving ergonomics and reducing fatigue.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional foregrip is installed in line with the rear grip in the vertical plane of the barrel, then the结构简单 (structure is simple), but the ergonomics deteriorate causing stress and discomfort to users
Solution Approach 1:
The foregrip is offset horizontally from the vertical plane of the barrel, moving the grip alignment from a single-plane (vertical) configuration to a multi-dimensional arrangement. This horizontal offset creates a more ergonomic configuration where the support hand and arm align better with the barrel, reducing user stress and discomfort while maintaining structural simplicity through the offset coupling mechanism
2Ease of operation
If the support arm is misaligned with the barrel due to conventional foregrip positioning, then the device complexity is reduced, but the user comfort and potential injury risk worsen
Solution Approach 1:
The foregrip coupling is positioned asymmetrically relative to the barrel's vertical plane, creating a horizontal offset that asymmetries the grip alignment. This asymmetric positioning allows the support arm to naturally align with the barrel during operation, improving user comfort and reducing stress and discomfort while maintaining a relatively simple structural design
3Ease of operation
If the foregrip is positioned to align the support hand with the barrel, then user comfort improves, but the coupling structure complexity increases
Solution Approach 1:
The coupling portion acts as an intermediary element that bridges the foregrip and the fore-end of the long gun. It provides the necessary horizontal offset functionality while maintaining a relatively simple structural design, serving as a mediator between the ergonomic requirements and the structural constraints of the firearm system

AI summary
An axially offset foregrip assembly for a long gun has a grip portion having a first grip axis, with a middle portion of the grip portion configured to be grasped by a hand of a user about the first grip axis. The foregrip assembly also has a coupling portion for coupling between the middle portion of the grip portion and a fore-end of a long gun. The long gun has a barrel having a longitudinal axis and a rear grip having a second grip axis, which together define a vertical barrel plane. The coupling portion is configured to couple the grip portion to the fore-end of the long gun such that the first grip axis is in a vertical grip plane horizontally offset from the vertical barrel plane, with the vertical grip plane and the first grip axis substantially parallel to the vertical barrel plane.
