Firearm Casing Catcher with One-Hand Mounting and Deflector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional firearm shell casing ejection systems pose hazards due to hot, uncollected spent brass, which can be difficult and cumbersome to manage, especially with existing brass catchers being bulky and laborious to use.
Innovation Solution
A firearm shell casing catching system that can be easily attached and detached with one hand, using a mounting assembly that contacts the firearm at no more than two points without screws or hardware, featuring a detachable hopper capable of holding spent casings from a 30-round magazine and a casing deflector to safely direct ejected casings into the hopper.

Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional brass catchers are used to collect spent casings, then the hazard from hot spent brass is reduced, but the device becomes bulky and difficult to use
Solution Approach 1:
The casing catching system is divided into separate functional components: a mounting assembly that attaches to the firearm, a deflector that redirects casings, and a hopper that collects them. This segmentation allows each component to be optimized independently and enables easy attachment/detachment without requiring a bulky integrated structure.
Solution Approach 2:
The deflector acts as an intermediary element between the ejection port and the hopper, redirecting spent casings into the collection container. This intermediary mechanism enables efficient casing capture without requiring the user to manually reach for or manipulate a large brass catcher.
2Reliability
If extensive mounting hardware is used to secure the brass catcher, then the device is stable and secure, but the attachment mechanism becomes laborious and complex
Solution Approach 1:
The mounting assembly incorporates flexible or adjustable elements that allow dynamic adaptation to different firearm configurations. This enables reliable attachment without requiring extensive rigid mounting hardware, simplifying the attachment mechanism while maintaining security.
Solution Approach 2:
The mounting system utilizes parameters such as friction, tension, or geometric interlocking rather than extensive screw and fastener assemblies. By changing the attachment parameters from mechanical fastening to alternative securing methods, the system achieves reliable mounting with reduced complexity.
3Quantity of substance
If a large capacity hopper is used to hold spent casings from a 30-round magazine, then the collection capacity is sufficient, but the device size increases
Solution Approach 1:
The hopper is designed to nest within or attach compactly to the mounting assembly, maximizing space utilization. This nested configuration allows the hopper to provide sufficient capacity for 30-round magazine output while maintaining a compact overall device footprint.
Solution Approach 2:
The hopper utilizes vertical or three-dimensional space efficiently rather than extending horizontally. By organizing the collection capacity in multiple dimensions, the system achieves adequate capacity without increasing the device's lateral footprint.
