Crescent Clamping Piece for Firearm Barrel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm barrel connection methods, such as screws, gluing, or pinning, make it impossible to change or dismantle the barrel once attached to the system sleeve, lacking a secure and easy release mechanism.
Innovation Solution
A barrel clamp with a crescent-shaped clamping piece in the system sleeve's receptacle provides a three-point clamping system, allowing axial and radial clamping, and can be easily released by moving the clamping piece, featuring a clamping screw for adjustable holding force and anti-rotation protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connection methods (screws, gluing, pinning) are used to attach the barrel to the receiver, then the barrel connection is secure and stable, but the barrel cannot be replaced or disassembled
Solution Approach 1:
The clamping device is divided into separate components: a clamping body with clamping elements and a actuating mechanism. This segmentation allows the clamping system to be released and repositioned, enabling barrel replacement while maintaining secure connection during use. The clamping elements can be independently actuated to release the barrel from the receiver.
Solution Approach 2:
The clamping system transitions from a static permanent connection to a dynamic reversible connection. The clamping elements can be actively engaged to secure the barrel or disengaged to allow removal. This dynamic capability enables the system to provide both secure retention during operation and easy replaceability when needed.
2Adaptability or versatility
If a clamping mechanism is introduced to enable barrel replacement, then adaptability improves, but the device complexity increases
Solution Approach 1:
The clamping elements are designed to maintain continuous contact with the barrel through elastic deformation, providing self-adjusting clamping force. The system uses the barrel's own geometry (cylindrical end with specific radius) to engage with the clamping elements, reducing the need for additional adjustment mechanisms and simplifying the overall structure.
Solution Approach 2:
The clamping force is controlled by changing the deformation parameter of the elastic clamping elements. By adjusting the degree of elastic deformation through the actuating mechanism, the clamping force can be varied to securely hold different barrel configurations without requiring complex mechanical adjustments.
3Device complexity
If point connection with clamping screws is used, then the structure is simple, but the clamping effectiveness is insufficient compared to surface contact
Solution Approach 1:
The clamping contact is extended from a zero-dimensional point contact (screw tip) to a one-dimensional line contact along the clamping surface, and potentially to two-dimensional surface contact. This dimensional expansion increases the contact area between the clamping elements and the barrel, improving clamping effectiveness and distribution of clamping forces.
Solution Approach 2:
The clamping elements feature curved or rounded contact surfaces that match the cylindrical geometry of the barrel end. This curvature optimization ensures optimal contact between the clamping elements and the barrel surface, maximizing the effective clamping area and improving the reliability of the connection compared to flat or pointed contacts.
