Firearm Scope Mount Wedge Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scope mounting devices for firearms are problematic due to the use of many screws that are difficult to properly torque, allow forward and rearward movement on the Picatinny rail, and can damage the rail or firearm receiver, especially with quick-disconnect systems that snag on gear.
Innovation Solution
A scope mounting system featuring a base with dovetail slots and a wedge mechanism that engages the side surfaces of the firearm rail, reducing the number of screws needed and preventing movement through a secure locking mechanism, including hinged scope rings and a wedge fastener that applies downward clamping force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple screws are used to secure the scope mounting device to the rail, then the device can be firmly attached, but the screws are difficult to properly torque and may damage the rail or firearm receiver
Solution Approach 1:
The patent replaces the traditional multi-screw mechanical fastening system with a wedge-based locking mechanism. The wedge engages with the rail's undercut geometry to provide secure attachment without requiring multiple screws, thereby eliminating the risk of screw-induced rail damage while maintaining strong attachment.
Solution Approach 2:
The invention changes the attachment mechanism from threaded screw connection to wedge-shaped geometric engagement. The wedge's angled surface converts insertion force into lateral clamping force against the rail's undercut, providing secure attachment through geometric constraint rather than threaded fastening.
2Ease of operation
If traditional scope mounting devices are used, then the scope can be mounted, but the devices allow forward and rearward movement on the Picatinny rail
Solution Approach 1:
The patent replaces traditional set-screw or cam-based locking mechanisms with a wedge that engages the rail's undercut geometry. This wedge design provides inherent positional stability by mechanically interlocking with the rail's angled surfaces, preventing forward and rearward movement while maintaining mounting simplicity.
3Ease of operation
If quick-disconnect systems with levers are used, then rapid scope removal is enabled, but the lever continually snags on gear and may damage the Picatinny rail or firearm receiver
Solution Approach 1:
The patent extracts the quick-disconnect functionality from the scope mounting system entirely. By using a wedge-based permanent attachment mechanism, the design eliminates the need for levers and quick-release features, thereby removing the source of lever snagging and potential damage while maintaining secure, stable scope mounting.
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 system securely attaches scopes to firearms with reduced risk of damage, ensures consistent torque, and prevents movement, enhancing the reliability and accuracy of scope mounting.
Implementation Method 1
a wedge mechanism coupled to the base and configured to engage side surfaces of a groove formed in the firearm rail
