Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms lack the combination of high precision, variability, short length, and high security, particularly in designs that allow for easy caliber changes and stable operation with heavy recoil.
Innovation Solution
The firearm features a modular design with a shoulder support, magazine shaft, trigger, and safety device positioned on top, allowing for a shorter construction length. It includes a rotary head closure with inclined threaded segments for enhanced locking, and a locking system with a knee lever arrangement for secure operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the lock and safety device are mounted on the top of the receiver instead of the underside, then the overall length of the firearm is reduced, but the complexity of the trigger mechanism increases
Solution Approach 1:
The patent relocates the lock and safety device from the traditional underside mounting to the top of the receiver, utilizing the vertical dimension differently. This dimensional repositioning allows the trigger mechanism components to be arranged in a more compact configuration, reducing the overall length of the firearm while distributing complexity across different spatial planes rather than concentrating it in a single area.
2Reliability
If a rotary head closure with inclined threaded segments is used, then the locking reliability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs asymmetric inclined threaded segments on the rotary head closure, where the threads are angled relative to the longitudinal axis rather than being perfectly symmetric. This asymmetric design creates a mechanical advantage that enhances locking reliability through self-locking characteristics, while the specific angle selection balances the manufacturing precision requirements by avoiding overly complex thread geometries.
3Adaptability or versatility
If the firearm is designed to accommodate multiple calibers from .223 Remington to .50 BMG, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements a segmented modular architecture where the firearm is divided into interchangeable components including the barrel, bolt, magazine, and receiver sections. Each segment is designed with standardized interface features that allow different caliber configurations to be assembled by swapping modules rather than redesigning the entire system. This segmentation enables caliber adaptability while containing complexity within discrete, manageable components.
Solution Approach 2:
The patent creates universal interface standards and mounting features that allow a single base platform to support multiple caliber configurations. The receiver, for example, incorporates universal attachment points and dimensional tolerances that accommodate various barrel and bolt assemblies, enabling one firearm chassis to perform multiple functions across different calibers from .223 Remington to .50 BMG without requiring complete redesign.
4Ease of manufacture
If the magazine shaft is positioned at the rear transverse limit, then the ease of assembly is improved, but the structural stability under heavy recoil worsens
Solution Approach 1:
The patent incorporates preliminary reinforcement features at the magazine shaft location, such as pre-stressed mounting points and reinforced receiver walls, that are built into the base structure before the magazine is installed. This preliminary strengthening allows the magazine shaft to be positioned at the rear transverse limit for ease of assembly while the pre-engineered structural support compensates for the potential weakness, maintaining recoil resistance without complicating the assembly process.
