Synthetic Firearm Receiver with Hinged Rear Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearms, particularly automatic rifles, require complex disassembly processes and heavy materials like steel and aluminum, which hinder weight reduction and increase costs, while safety concerns remain due to the lack of reinforcing connections in the rear receiver closure.
Innovation Solution
A firearm design featuring a single-piece synthetic receiver with a simplified disassembly mechanism, utilizing a foldable stock and a lower receiver made of synthetic material, where the rear closure is achieved through a hinged plate and spring-loaded system, allowing for easy opening and inspection without loose components or tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional metal receivers with complex disassembly mechanisms are used, then safety and structural strength are improved, but weight and device complexity increase
Solution Approach 1:
The receiver is made from a synthetic material that combines lightweight properties with sufficient mechanical strength to contain firing gases and support the bolt assembly, replacing traditional heavy metal materials while maintaining safety requirements
Solution Approach 2:
The receiver is divided into a main body and a separately removable rear closure element that can be quickly detached without tools, allowing rapid access for cleaning and maintenance while the main receiver structure remains intact and lightweight
2Reliability
If traditional metal receivers with reinforcing connections are used, then safety and structural strength are improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The synthetic material provides inherent strength-to-weight ratio that eliminates the need for complex reinforcing connections and internal bracing required in lightweight metal constructions, simplifying the overall receiver structure
Solution Approach 2:
The rear closure is separated as an independent removable element from the main receiver body, allowing the main receiver to have a simpler structure while the closure element provides the necessary sealing and structural completion
3Stability of the object's composition
If traditional complex disassembly mechanisms are used, then structural integrity is maintained, but ease of operation and maintenance speed decrease
Solution Approach 1:
The rear closure is designed as a separately removable module that can be quickly detached from the main receiver without tools or complex mechanisms, enabling rapid access for cleaning while the main receiver structure remains intact
Solution Approach 2:
The rear closure element is extracted as a distinct removable component from the receiver assembly, allowing it to be easily removed and reattached while maintaining the structural integrity of the main receiver body

AI summary
A firearm, in particular an automatic or semi-automatic rifle, with a simplified disassembly, comprising a receiver (12), a barrel (13), a bolt assembly (14), a foldable stock (16) and a removable lower receiver (17) comprising a magazine (19) and a release mechanism (20), is equipped with a lower receiver (17) inserted with shape coupling in the lower open part of said receiver (12) between a front seat (21) and a rear seat (22) of the receiver (12), wherein the front seat (21), coupled with at least one complementary surface (23) of the lower receiver (17), forms a front articulation (24) for the rotation of the lower receiver (17) with respect to the receiver (12), also comprising blocking means of the lower receiver (17) in at least two different positions.
