Solution Overview
Problem
Existing weapon systems require tools for assembly and disassembly, complicating maintenance and repair, and often rely on springs for firing pin tensioning, which can be unreliable.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional weapon systems use screw connections and tool-based assembly methods, then structural strength and connection reliability are improved, but assembly and disassembly complexity increases and maintenance time is extended
Solution Approach 1:
The weapon system is divided into modular components (barrel assembly, receiver, stock, magazine) that can be independently assembled and disassembled. Each module features standardized quick-connect interfaces with bayonet-style lugs and corresponding slots, allowing tool-free assembly while maintaining structural integrity through precise geometric mating surfaces.
Solution Approach 2:
The connection system transitions from static screw threads to dynamic bayonet-style quick-connect mechanisms. These features enable rapid engagement and disengagement through rotational motion, where the lug-slot interface provides both mechanical connection and alignment guidance, eliminating the need for threaded fasteners and reducing assembly steps.
2Device complexity
If spring-based firing pin tensioning systems are used, then simple mechanism design is achieved, but reliability deteriorates due to spring fatigue and inconsistency
Solution Approach 1:
The unreliable spring element is completely removed from the firing pin tensioning system. Instead, a dedicated tensioning mechanism using cam surfaces and lever arms provides consistent mechanical force to maintain firing pin readiness. This extraction eliminates spring fatigue issues while maintaining operational simplicity through pure mechanical advantage.
Solution Approach 2:
The spring-based elastic mechanical system is replaced with a cam-and-lever mechanical system that provides deterministic force application. The cam surface geometry ensures consistent firing pin tension through controlled mechanical motion, replacing the variable force characteristics of springs with precise geometric force transmission.
3Productivity
If modular weapon components are designed for tool-free assembly, then maintenance efficiency is improved, but manufacturing precision requirements increase to ensure proper fit and function
Solution Approach 1:
Standardized quick-connect interfaces are designed with universal geometric features (lug dimensions, slot orientations, engagement forces) that work across multiple weapon platform variants. This universality allows the same connection mechanism to serve both rapid assembly functions and precise alignment requirements, reducing the need for variant-specific precision manufacturing.
Solution Approach 2:
The bayonet-style connection features incorporate self-aligning and self-centering geometric properties where the lug-slot interface automatically guides components into proper alignment during assembly. This self-service alignment mechanism reduces dependency on high-precision manual positioning and compensates for normal manufacturing tolerances through inherent geometric constraints.

AI summary
The aim of the invention is to devise a weapon (100) which has a completely modular design. For this purpose, the weapon (100) is subdivided into weapon-specific assemblies which are designed as carrier units of the components and/or of the modular assemblies of the weapon (100). A first assembly can be a modular weapon housing (3). Said weapon housing (3) consists of a carrier unit into which a breech system of the weapon (100) and its components are built. Another modular assembly is a weapon cradle (2). Into this modular assembly the weapon housing (3) module with breech system is integrated. The weapon housing (3) module can be complemented with the weapon barrel module. In a specific embodiment, the weapon barrel module is a weapon barrel bundle (10) with at least one weapon barrel (5, 5', 5''). Another modular assembly, a weapon drive (1), is connected to the weapon cradle (2). Said weapon drive comprises an external drive (1.1) and the breech drive (35, 36, 37). The components are connected to the modular assemblies and the modular assemblies to each other by means of rails and guides (15.1, 21.1) and complementary rails and guides (3.1, 3.2) for the assemblies (3), by binders (31) and holders (33), by pins (33, 34), bolts (31.1, 2.6) and quick release fasteners (22,.2). The weapon according to the invention is preferably an externally powered weapon (100).
