Firearm Grip Snap-In Mechanism for Stable Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handgun designs face challenges in providing easy and simple assembly of additional parts, particularly in the rear grip area, which often results in clumsy and difficult assembly due to multiple parts, and lack mechanical stability.
Innovation Solution
A snap-in connection mechanism is introduced, featuring a recess and protrusion design on the handle, where the additional part is secured by a pin, allowing for easy assembly and disassembly through elastic deformation, ensuring mechanical stability without destructive fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional parts are attached to the grip using multiple components and complex fixation methods, then the mechanical stability is improved, but the assembly complexity increases and ease of assembly deteriorates
Solution Approach 1:
The patent combines multiple fixation functions into a single integrated snap-in connection mechanism. The snap-in connection integrates the protrusion, recess, and elastic deformation elements into one unified structure that simultaneously provides attachment and stabilization, eliminating the need for separate fixation components while maintaining mechanical stability.
Solution Approach 2:
The snap-in connection serves multiple functions: it provides mechanical attachment, ensures positional accuracy, and enables easy assembly and disassembly. This multi-functional design replaces complex multi-component fixation systems with a single element that performs all necessary functions.
2Reliability
If traditional fixation methods like screws or adhesive tape are used, then the mechanical stability is achieved, but the ease of assembly and disassembly deteriorates
Solution Approach 1:
The snap-in connection utilizes elastic deformation to create a dynamic fixation mechanism. The elastic element deforms during assembly to allow the additional part to snap into place, then maintains constant elastic force to hold the connection. For disassembly, the elastic element can be deformed to release the connection, enabling easy removal without destructive tools.
3Ease of operation
If the additional part extends to the upper edge of the grip, then the comfort and ergonomics are improved, but the assembly difficulty increases due to cramped space
Solution Approach 1:
The snap-in connection is designed to be self-aligning and self-securing. The geometric relationship between the protrusion and recess automatically guides the additional part into the correct position during assembly, eliminating the need for complex alignment procedures in the cramped upper grip area. The elastic deformation provides self-adjustment during the snapping process.

Function Achieved in This Case
The solution provides a robust, easy-to-assemble additional part that enhances the mechanical stability and comfort of the handgun grip, accommodating various hand sizes and shapes, while being adaptable to different firearms.
Implementation Method 1
to release it is only necessary to remove the retaining pin and then to release it from the upper form-fitting connection by elastic deformation of the additional part

AI summary
The firearm has a receiver (5) that comprises an anchoring area with a through hole (10) which aligns with an accessory unit to insert a fastening pin. An associated anchoring area on the accessory unit has a collar that engages a lower edge (6) of the receiver when the accessory unit is mounted on the receiver. A first projection of the receiver functions together with a second indentation of the accessory unit and the first indentation on the rear portion of the receiver functions together with the second projection in the manner of a snap mechanism.
