Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern semi-automatic pistols face challenges with the integration of sound suppressors, electro-optical sights, and the blurring distinction between pistols and carbines, requiring modular capabilities to adapt to various applications while maintaining functionality.
Innovation Solution
A modular compact firearm system featuring a non-reciprocating, interchangeable barrel, universal action system, and various grip frames, which includes a receiver with locking surfaces and guide rails, a partially locked breechblock assembly, and interchangeable barrel and grip assemblies to accommodate different configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a sound suppressor is integrated with a short-recoil pistol action, then suppressor functionality is achieved, but recoil interference increases requiring additional decoupling mechanisms
Solution Approach 1:
The firearm is divided into separate modular components including the receiver assembly, barrel assembly, and grip assembly that can be independently configured. The sound suppressor is integrated as a separate module in the barrel assembly rather than requiring modifications to the receiver action.
Solution Approach 2:
The universal action system is designed to accommodate multiple configurations including pistol, carbine, and suppressed variants through standardized interfaces. A single receiver design works with different barrel assemblies, eliminating the need for separate decoupling mechanisms for each configuration.
2Measurement precision
If electro-optical sights are mounted on a pistol, then aiming precision is improved, but the mounting structure becomes unwieldly or alters momentum balance
Solution Approach 1:
The receiver assembly includes integrated mounting interfaces for electro-optical sights that maintain proper alignment without requiring complex cantilever structures. The universal action system preserves momentum balance across all configurations through consistent mass distribution principles.
3Adaptability or versatility
If pistol specifications are made modular for easy reconfiguration, then adaptability between handgun and carbine configurations is improved, but device complexity increases
Solution Approach 1:
The firearm system is segmented into three main interchangeable assemblies: receiver, barrel, and grip. Each assembly has standardized interfaces that allow rapid reconfiguration between pistol and carbine configurations without requiring complex fastening mechanisms or specialized tools.
Solution Approach 2:
Multiple functional features are merged into unified components. The universal action system combines the receiver, trigger mechanism, and sight mounting into a single integrated assembly that works with all barrel and grip configurations, reducing the total number of interchangeable parts needed.

AI summary
An assembly for a modular, compact firearm includes a universal action and an interchangeable, non-reciprocating barrel. The barrel may directly mount various optical sighting systems and provide integral muzzle compensation and sound suppression capabilities. The firearm utilizes a universal action comprised of a slide assembly, breechblock assembly, recoil assembly, and receiver which mounts a variety of barrel assemblies and assembles into a variety of different grip frames. The action of the firearm utilizes a partially-locked breechblock which amplifies the inertia of a slide.
