Firearm Muzzle Attachment Mechanism With Tapering Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm muzzle attachment mechanisms, such as those described in the UK patent GB2242476, face issues with secure engagement during shooting due to heat and vibration generated by bullets, leading to potential loosening and safety hazards.
Innovation Solution
A firearm muzzle attachment mechanism comprising a tapering adapter with an outer threaded end, a hollow adapter with an internally threaded portion, and a muzzle attachment with a flanged taper wall and middle-threaded portion, along with a wire spring providing tension to secure the components together, preventing loosening during shooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple clamp unit is used to attach the silencer, then the device complexity is reduced, but the reliability of engagement during shooting deteriorates due to loosening from heat and vibration
Solution Approach 1:
The attachment mechanism is divided into multiple functional segments: an elongated member with threading, a hollow adaptor unit with internally threaded portion, and a locking body with engagement features. Each segment performs a specific function, and together they create a more reliable attachment system that resists loosening during shooting.
Solution Approach 2:
The hollow adaptor unit is designed to receive and nest within the elongated member, while the locking body engages with both components. This nested configuration allows the components to work together in a compact arrangement, improving engagement stability without excessive complexity.
2Reliability
If a secure engagement mechanism is implemented to prevent loosening, then the reliability is improved, but the device complexity increases due to additional components
Solution Approach 1:
The elongated member features external threading that automatically engages with the internally threaded portion of the hollow adaptor unit during assembly. This self-engaging threaded connection provides secure attachment without requiring additional locking mechanisms or complex assembly procedures.
Solution Approach 2:
The hollow adaptor unit acts as an intermediary component between the elongated member and the locking body. It provides the internally threaded portion that receives the elongated member and also engages with the locking body, facilitating a secure three-component connection.
3Strength
If the components are tightly engaged to prevent breaking apart, then the strength of connection is improved, but the ease of operation deteriorates due to difficulty in assembly and disassembly
Solution Approach 1:
The traditional mechanical interference fit or weld connection is replaced with a threaded engagement system. The external threading on the elongated member engages with the internally threaded portion of the hollow adaptor unit, providing strong connection strength while allowing for easy manual assembly and disassembly using standard threading tools.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures secure mounting of the muzzle attachment without breaking apart during shooting, enhancing safety by maintaining engagement between the adapter, attachment, and muzzle device, even under high-speed bullet passage.
Implementation Method 1
a wire spring providing tension to secure the components together, preventing loosening during shooting
