Firearm Rail Insert with Compressible Locking Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current firearm rail systems, such as Weaver, Picatinny, KeyMod, and M-LOK, face limitations in providing a standardized and efficient method for attaching rail covers, leading to a need for continuous improvement in attachment systems for accessories like scopes and sights.
Innovation Solution
A rail insert system comprising a backing member with locating and locking pins, featuring compressible members and chamfered portions for secure engagement with firearm rails, along with grip indentations for improved fit and ejection indentations for mold release, is introduced. The system includes a method of manufacturing using a mold to produce the rail insert with specific geometries for optimal attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional rail systems (Weaver, Picatinny, KeyMod, M-LOK) are used to attach firearm accessories, then various accessories can be mounted on the firearm rail, but the attachment method lacks standardization and efficiency for rail covers specifically
Solution Approach 1:
The rail insert is designed to work with multiple rail systems including Weaver, Picatinnym, KeyMod, and M-LOK rails, providing a universal attachment solution for rail covers across different firearm platforms. The insert's backing member and pin configuration enable compatibility with various rail types while maintaining a standardized attachment method.
Solution Approach 2:
The locking pin incorporates a compressible member that changes its physical state during attachment - compressed during installation to allow positioning, then expands to lock the rail cover securely. This parameter change enables both easy installation and secure retention with a standardized approach.
2Reliability
If a secure attachment system is implemented with locating and locking pins, then the rail cover attachment reliability is improved, but the device complexity increases
Solution Approach 1:
The backing member integrates multiple functions into a single component: it provides structural support, positions the locating pin, positions the locking pin, and incorporates the compressible member. This merging reduces the number of separate parts while maintaining secure attachment through the integrated pin system.
Solution Approach 2:
The compressible member on the locking pin provides self-aligning and self-locking functionality. During installation, the compressible member allows the locking pin to be positioned, then automatically expands to lock the rail cover in place without requiring additional tools or complex mechanisms.
3Reliability
If a compressible member is added to the locking pin for secure engagement, then the attachment reliability is improved, but the manufacturing complexity increases
Solution Approach 1:
The compressible member is integrated into the locking pin as part of a single molded component rather than a separate part. This allows the use of moldable materials with appropriate elastic properties to be formed in one manufacturing step, reducing assembly complexity while maintaining the secure engagement function.
