Weapon Front Handle With Pivoting Grip For Ergonomic Adaptation

Solution Overview

Problem

Conventional firearm front handles are often cylindrical and lack ergonomics, leading to discomfort for users, and existing ergonomic designs may not be fully adaptable to individual preferences or weapon characteristics.

Innovation Solution

A front handle with a pivoting grip and control ring system that allows for adjustable positioning of grooves and control buttons, enabling users to customize the handle's configuration based on their hand position, weapon weight, and recoil patterns, making it usable by both left- and right-handers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If the front handle is shaped with recesses to facilitate finger placement, then the grip force is increased, but the user comfort deteriorates

Engineering Contradiction:

Core Design Contradiction:

ForceVSEase of operation

Solution Approach 1:

The grip is made rotatable relative to the plate about the longitudinal axis, allowing the user to dynamically adjust the angular position of the grooves to find the most comfortable orientation while maintaining adequate grip force

Inventive Principle:

Principle #15Dynamics

2Ease of manufacture

If the front handle is designed with a fixed symmetric grip position, then the manufacturing is simplified, but the adaptability to different users and weapon characteristics is reduced

Engineering Contradiction:

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The grip can be rotated to different angular positions relative to the plate, allowing adaptation to left-handed or right-handed users and different weapon characteristics while maintaining a simple symmetric base design that is easy to manufacture

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

While the base design remains symmetric for ease of manufacture, the rotatable grip allows the user to create an asymmetric configuration optimized for their specific hand position and weapon characteristics

Inventive Principle:

Principle #4Asymmetry
