Solution Overview

Problem

Conventional vertical fore grips do not allow for user customization to accommodate varying physical features and preferences, such as hand size, arm length, and dexterity, which can limit control and comfort during firearm operation, especially in multi-user environments like military or police organizations.

Innovation Solution

An adjustable vertical fore grip system that includes a grip extension with a bolt assembly, allowing for length adjustment and rotation in predetermined increments, along with a clamping mechanism for secure attachment to a firearm, enabling users to customize the grip's position and accessory placement according to their anatomical needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional vertical fore grip is used, then the user can steady the firearm and resist recoil, but the user cannot customize the grip to accommodate varying physical features such as hand size and arm length

Engineering Contradiction:
Improvecustomization capabilityVSAvoidcontrol and comfort
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The fore grip incorporates adjustable components including a telescoping barrel extension that can be extended or retracted, and a rotation mechanism that allows the grip to be rotated to different angular positions. These dynamic adjustments enable the grip to adapt to different user anatomical features while maintaining optimal control and comfort during firearm operation.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention changes physical parameters of the fore grip by providing adjustment mechanisms that modify the effective length and angular orientation of the grip. The telescoping mechanism changes the linear dimension, while the rotation mechanism changes the angular parameter, allowing the grip to be customized for different users' physical features.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the fore grip is made adjustable to fit different users, then customization capability improves, but the device complexity increases due to additional adjustment mechanisms

Engineering Contradiction:
Improveuser customizationVSAvoidadjustment mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The fore grip is divided into separable components including a main body, a telescoping barrel extension, and a rotation mechanism. This segmentation allows each component to perform its specific adjustment function independently, making the overall system more versatile while keeping individual components relatively simple and manageable.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adjustment mechanisms are designed to serve multiple functions: the telescoping mechanism adjusts both the length of the barrel extension and the overall grip length, while the rotation mechanism accommodates different hand orientations and anatomical features. This multi-functionality reduces the need for separate adjustment systems for each parameter.

Inventive Principle:
Principle #6Universality (Multi-functionality)
