Urban Combat Firearm with Cycle-Controlled Feed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current infantry firearms are antiquated and inadequate for modern urban combat environments, lacking in weight reduction, reliability, maintainability, and effectiveness in close-range engagements, with existing designs failing to address the need for high first-round hit probability and single-round lethality.
Innovation Solution
Development of an automatic gun with a flechette shotshell and a multiple-shot 40 mm grenade launcher, featuring a recoil-operated belt-fed mechanism, reduced felt recoil, and a modular design for easy maintenance and operation, capable of using both link-belt and magazine feed systems, and integrating with a folding shoulder stock and polymer components for reduced weight and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional infantry firearms are used, then they have been in service for decades, but they are too heavy and inadequate for modern urban combat environments
Solution Approach 1:
The firearm is divided into modular components including a receiver assembly, barrel assembly, magazine assembly, and stock that can be independently manufactured and assembled. This segmentation allows each component to be optimized for weight while maintaining overall system reliability through proven sub-component designs.
Solution Approach 2:
The firearm design incorporates universal interfaces and standardized components that allow the same basic platform to serve multiple combat roles through different ammunition types and accessory attachments, reducing the need for multiple specialized weapons and thereby reducing total system weight.
2Reliability
If ammunition feed is not controlled by weapon cycle, then feeding mechanism is independent, but reliability decreases due to potential desynchronization
Solution Approach 1:
The ammunition feed system is designed to be automatically controlled by the weapon's own cycle events. The feed mechanism responds to receiver pressure changes and bolt movement without requiring separate control systems, allowing the weapon to self-regulate feeding timing and ensure reliable synchronization.
Solution Approach 2:
The feed control function is merged with the existing weapon cycle mechanisms. Pressure-sensitive feed triggers and bolt-coupled feed actuators combine the feeding function with already-present moving parts, avoiding additional complexity while ensuring reliable coordination between firing and feeding operations.
3Weight of moving object
If gun weight is reduced for infantry portability, then carried weight decreases, but structural strength and durability may be compromised
Solution Approach 1:
The firearm incorporates composite materials such as polymer stocks and handguards, aluminum alloy receiver components, and stainless steel barrel assemblies. These composite and alloy materials provide high strength-to-weight ratios, allowing significant weight reduction while maintaining or improving structural strength and durability compared to traditional all-steel designs.
4Reliability
If firearm is optimized for urban combat with high first-round hit probability, then lethality increases, but magazine capacity may be reduced
Solution Approach 1:
The firearm employs a dynamic fire control system with adjustable semi-automatic and fully automatic modes. This allows the weapon to deliver precise single shots when high first-round hit probability is needed, or switch to rapid automatic fire when magazine capacity becomes the limiting factor, providing flexibility to optimize for different combat scenarios.
