Movable Recoil Bracket Structure for Compact Handgun Durability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handgun designs face issues with recoil force distribution and mechanical failures at the recoil lug and fastener bores, particularly in compact modular handguns, leading to early component failure and reduced product life.
Innovation Solution
A movably retained recoil lug in the grip module, made of materials like aluminum or metal-infused polymer, which allows for better distribution of recoil forces and reduces mechanical stress, enhancing durability and clearance.

Engineering Contradiction Analysis
1Reliability
If a fixed recoil lug retained by fasteners is used, then the structure is simple and easy to manufacture, but mechanical failures occur at the recoil lug and fastener bores leading to reduced product life
Solution Approach 1:
The recoil lug is made movable relative to the grip module, allowing it to move rearward during firing and return to its original position. This dynamic capability distributes recoil forces across multiple contact points and prevents stress concentration at fixed fastener locations, thereby improving reliability and product life without requiring complex retention mechanisms
Solution Approach 2:
The recoil lug is separated from the grip module as a distinct movable component rather than being fixedly attached. This segmentation allows the recoil lug to independently move and distribute forces, preventing failures at the interface between the lug and grip module while maintaining structural integrity
2Area of stationary object
If a smaller contact surface is used for the recoil lug, then greater working clearance is achieved which is helpful in compact handguns, but force distribution may be insufficient
Solution Approach 1:
The movable recoil lug dynamically adjusts its position during firing, moving rearward to absorb recoil forces and then returning to its original position. This dynamic movement allows the lug to maintain effective force distribution even with a smaller contact surface area, enabling compact handgun designs with adequate working clearance

AI summary
A handgun grip module assembly includes a grip module with a handgrip portion, a slide portion, and a trigger guard extending between and connecting the handgrip portion to the slide portion. The slide portion extends longitudinally along a central axis and has opposed sidewalls and a bottom wall. The slide portion defines a bracket recess in the bottom wall and defines a receiver well between the opposed sidewalls and above the handgrip portion. A recoil bracket is movably disposed in the bracket recess. In some examples, the grip module can be made of a metal or a metal-infused polymer. During use, the recoil bracket can move in response to forces exerted on it during the firing cycle.
