Receiver Cover with Dual Locking Mechanism for Accessory Rail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a receiver cover for guns, such as AK-47 variant rifles, that provides a stable platform for mounting tactical accessories while ensuring secure attachment and easy operation.
Innovation Solution
A receiver cover with an elongated member featuring a distal end for connecting to gun parts, a proximal end with a locking mechanism, and a tactical accessory rail, which includes a positioning member connected to an anchor that can be rotated to secure the cover to the rifle, and a second locking mechanism with a lever and biasing member for additional stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a receiver cover is designed to provide a stable platform for mounting tactical accessories, then the stability and reliability of accessory mounting is improved, but the device complexity increases due to the need for locking mechanisms and secure attachment systems
Solution Approach 1:
The receiver cover is divided into separate functional components including the cover body, locking mechanism, and accessory rail mounting interface. This segmentation allows each component to be optimized independently while maintaining overall stability for accessory mounting.
Solution Approach 2:
The locking mechanism incorporates movable elements such as levers and biasing members that can transition between locked and unlocked states. This dynamic design provides secure attachment when locked while allowing easy operation when unlocked, resolving the contradiction between stability and complexity.
2Reliability
If a dual locking mechanism is implemented to ensure secure attachment, then the reliability of attachment is improved, but the ease of operation decreases due to the additional locking steps required
Solution Approach 1:
The biasing member automatically applies force to the lever to maintain the locked position without requiring additional energy input from the user. The mechanism self-regulates to ensure secure attachment while minimizing the operational steps required by the user.
Solution Approach 2:
The manual locking action is augmented by the mechanical biasing member that automatically maintains the locked state. This substitution reduces the operational burden on the user while ensuring reliable attachment through the combined mechanical action of the lever and biasing member.
3Ease of operation
If the positioning member is made rotatable to enable easy adjustment, then the ease of operation is improved, but the stability of the locked position may be compromised
Solution Approach 1:
The rotatable positioning member incorporates discrete engagement positions that provide periodic stable states during rotation. This allows easy adjustment between positions while ensuring stable locking at each engagement point, resolving the contradiction between ease of adjustment and locked position stability.

AI summary
A cover for a receiver of a gun that may include an elongated member having a first longitudinal axis, the elongated member including a distal end portion which may include a leading edge which is configured and dimensioned to connect with a gun part, and a proximal end portion which is spaced from the distal end portion along the first longitudinal axis. The elongated member may include a first locking mechanism adjacent the proximal end wall. The first locking mechanism may be secured to a recoil spring guide of the gun. Also, the elongated member may include a second locking mechanism adjacent the distal end portion. The second locking mechanism may be secured to a rear sight base of the gun. The elongated member may include an accessory rail.
