Hybrid Pistol Frame Kit Modular Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The firearms industry lacks a system and process for effectively customizing firearms to expand their functionality, such as converting a pistol into a rifle or providing a pistol brace-equipped handgun, beyond traditional methods of replacing parts.
Innovation Solution
A prefabricated synthetic frame, known as a 'Ghost Gun' or '80% receiver,' is provided, which can be processed by the end user to receive existing or new firearm components, forming a hybrid firearm with features like a D-shaped mount for accessories and a Picatinny rail for mounting a shoulder stock.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional OEM parts are used for firearm modification, then reliability and compatibility are maintained, but adaptability and customization options are limited
Solution Approach 1:
The firearm is divided into modular components (frame, upper receiver, lower receiver, barrel, grip, stock) that can be independently selected and assembled. The frame kit includes separate modules for different configurations (pistol, rifle, shotgun) allowing users to segment and reconfigure components based on specific needs while maintaining standardized interfaces for reliable assembly.
Solution Approach 2:
The frame kit is designed as a universal platform that can receive multiple types of components (barrels, grips, stocks, accessories) through standardized mounting interfaces. The same frame can be configured for different firearm types and tactical applications, providing multi-functionality without requiring separate dedicated frames for each configuration.
2Adaptability or versatility
If custom firearm configurations are created, then functionality and adaptability are enhanced, but manufacturing complexity and cost increase
Solution Approach 1:
The frame kit is pre-manufactured with pre-drilled holes, pre-cut openings, and pre-formed mounting surfaces in standardized locations. Accessories and components are pre-designed with corresponding attachment features, so that during assembly no additional manufacturing steps are needed - the components are ready to be directly installed in their final positions.
Solution Approach 2:
The kit uses standardized dimensional parameters and mounting specifications across all components. Thread sizes, hole patterns, and attachment dimensions are maintained within tolerance ranges that allow interchangeable parts. This standardization enables custom configurations to be manufactured efficiently using existing tooling and processes without requiring unique manufacturing for each variation.
3Adaptability or versatility
If multiple pistol components are installed in the receiving cavity, then functionality is expanded, but device complexity increases
Solution Approach 1:
The frame kit includes a receiving cavity designed to nest and accommodate multiple components in a hierarchical arrangement. The barrel is positioned within the upper receiver, which sits on the frame, with the grip and stock attaching to external surfaces. This nested configuration allows multiple components to be integrated without increasing overall complexity, as each component fits within or attaches to the existing structure.
Solution Approach 2:
Multiple mounting functions are combined into integrated features. The frame includes combined mounting points for both the barrel and grip that are formed as part of the same structural element. The receiving cavity itself serves as both a structural component and a mounting interface for multiple parts, reducing the need for separate dedicated mounting features for each component.
