Solution Overview

Problem

Conventional methods for removing or replacing firearm grips are tedious, time-consuming, and often require tools, leading to inefficiencies in accommodating different user hand sizes and shapes, which can result in inaccurate shooting and safety issues due to unsuitable grip sizes.

Innovation Solution

An interchangeable grip system comprising a grip base piece and interchangeable grips with a pin-guide and spring mechanism, allowing for quick and easy installation and removal without specialized tools, enabling customization and adaptability to various hand sizes and shapes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional methods are used to remove or replace firearm grips, then the grip can be changed, but the process is tedious, time-consuming, and requires tools

Engineering Contradiction:
Improvegrip interchangeabilityVSAvoidgrip removal and installation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The grip system is divided into separate components: a grip base piece that attaches to the firearm receiver, and interchangeable grip portions that can be independently removed and replaced. This segmentation allows the grip to be customized for different users without requiring tool-based disassembly of the entire grip assembly.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The interchangeable grip portion is designed to be easily extracted from the grip base piece through a simple sliding motion that releases a pin from a recess, eliminating the need to keep tools attached to or integrated with the grip for removal purposes.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If conventional methods are used to remove or replace firearm grips, then the grip can be changed, but the process is tedious and time-consuming

Engineering Contradiction:
Improvegrip interchangeabilityVSAvoidgrip removal and installation time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The grip system incorporates a dynamic locking mechanism using a spring-loaded pin that can quickly transition between engaged and disengaged states. This allows the grip to be securely attached when needed and rapidly removed when customization is required, significantly reducing the time investment compared to conventional fixed or tool-based replacement methods.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a universal grip is used on firearms, then the firearm can be used by multiple users, but it does not fit all hand sizes and shapes, resulting in less control and safety issues

Engineering Contradiction:
Improvegrip customizationVSAvoidfirearm control and safety
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The grip system allows different portions of the grip to have different characteristics by enabling the replacement of grip portions with different sizes, shapes, and textures. This local customization ensures that each user can select a grip configuration that specifically matches their hand anatomy, improving control and safety without compromising the universal compatibility of the base system.

Inventive Principle:
Principle #3Local quality

AI summary

Methods, systems, and apparatuses for interchangeable, customizable, and suitable grips for firearms are described. In some embodiments, the grip includes two components, a grip base piece and an interchangeable grip (e.g., an interchangeable grip attachment) of the firearm user's choice. The grip base piece attaches to the lower receiver held by a pistol grip screw and a lock washer. In some examples, the grip base piece may only be installed once, for example, initially prior to implementation of interchangeable grips (e.g., the grip base piece may not require any other attention or installation changes after the initial placement onto the lower receiver). Following the installation of the grip base piece on the lower receiver, interchangeable grips of users' choice may be connected to the grip base piece (e.g., and interchanged with other interchangeable grips) via utilizing a grip interface (e.g., a T-shaped mating tab of the interchangeable grip).
