Modular Handgun Grip Module for Accessory Rail Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a modular grip module system that is compatible with existing handguns and allows for the attachment of various tactical accessories, such as stocks and optics, to enhance performance and versatility.
Innovation Solution
A grip module system comprising a lower receiver, pistol grip, buffer tube attachment point, and accessory rail, which can be configured with materials like carbon fiber, polymer, or metal, and is compatible with handguns like the Sig Sauer P320 and Springfield Echelon, allowing for the attachment of accessories like optics and stocks through 1913 picatinny rails and quick-disconnect sling points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a modular grip module system is added to existing handguns, then versatility and accessory compatibility are improved, but device complexity increases
Solution Approach 1:
The grip module system incorporates universal attachment interfaces including 1913 Picatinny rails and M-LOKT slots that can accommodate multiple types of accessories (optics, lights, lasers, stocks, slings). This multi-functional design allows a single handgun platform to perform various tactical functions by simply changing accessories, resolving the contradiction between versatility and complexity through standardized universal interfaces.
Solution Approach 2:
The system divides the handgun into modular components: the base handgun remains unchanged while the grip module is a separate attachable unit containing the accessory rails and buffer tube attachment point. This segmentation allows users to add versatility through the modular grip module without permanently complicating the base handgun design, as the module can be attached or removed as needed.
2Adaptability or versatility
If accessory rails and buffer tube attachment points are added to the handgun, then functional versatility is improved, but manufacturing complexity increases
Solution Approach 1:
The accessory rails and buffer tube attachment point are integrated into a separate grip module rather than being added directly to the handgun receiver. This segmentation allows the base handgun to remain simple to manufacture, while the grip module with its complex attachment interfaces can be manufactured separately and attached, reducing the manufacturing complexity burden on the primary handgun production line.
Solution Approach 2:
The grip module uses standardized universal interfaces (1913 Picatinny rails, M-LOKT slots) that are well-established manufacturing standards. By adopting these existing universal standards rather than creating proprietary attachment systems, the manufacturing process leverages proven techniques and tooling, reducing overall manufacturing complexity despite the added functionality.

AI summary
A grip module system for a handgun or other firearm may include a lower receiver, a pistol grip affixed to the lower receiver, a buffer tube attachment point affixed to a rear portion of the lower receiver, and an accessory rail removably attached to a top of the buffer tube attachment point. The grip module system may be configured to accept and engage the firing components of various semi-automatic and automatic pistols or rifles.
