Elastomeric Damper Retainer for Firearm Recoil Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern firearms with modular components experience increased wear and failure due to unreduced recoil forces transmitted between rigid components, particularly when metal components interact, leading to premature degradation.
Innovation Solution
The implementation of resilient elastomeric dampers installed in grooves or cavities within firearm components without fasteners or adhesives, featuring a cutout design for flexibility and retention, which absorb and modulate impact forces between rigid surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If resilient elastomeric dampers are installed in grooves or cavities without fasteners or adhesives, then ease of installation and maintenance is improved, but retention reliability may worsen
Solution Approach 1:
The cavity is designed as a separate structural feature from the component body, creating a dedicated retention space that mechanically engages the damper. This segmentation allows the damper to be retained through the cavity geometry itself rather than requiring additional fastening elements, achieving both ease of installation and reliable retention.
Solution Approach 2:
The cavity acts as an intermediary structure between the component and the damper. Instead of directly fastening the damper to the component, the cavity serves as a mediating retention mechanism that holds the damper in place through its geometric configuration, eliminating the need for fasteners or adhesives while maintaining secure retention.
2Reliability
If the cavity cross-sectional area at the open end is made smaller than at the floor, then damper retention is improved, but manufacturing complexity may worsen
Solution Approach 1:
The cavity cross-sectional area parameter is deliberately varied along its length, being smaller at the open end and larger at the floor. This parameter change creates a tapered or flared geometry that mechanically retains the damper through friction and geometric interference, achieving reliable retention without complex fastening mechanisms while remaining manufacturable through standard cavity formation processes.

AI summary
A firearm damper and damping system is provided. The elastomeric damper can be retained in a cavity of a firearm component without the use of fasteners or adhesives. The damper can reduce the wear between surfaces that are subject to impact during firing and can extend the life of components such as the frame or receiver.
