Firearm Cleaning Patch Grip Preventing Plug Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Firearm barrel interiors accumulate debris such as carbon, soot, and dust, which are difficult to remove effectively and rapidly, especially in field use scenarios like military or hunting, where quick cleaning is crucial for maintaining firearm performance and longevity.
Innovation Solution
A novel cleaning patch system featuring a patch grip with an arbor and plug design that securely holds a cleaning patch, allowing for rapid assembly and use with a flexible cable or rigid rod to efficiently clean the barrel interior, preventing inadvertent rotation and ensuring effective debris removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If typical cleaning methods are used, then the cleaning process is simple, but the cleaning effectiveness is insufficient for tenacious debris
Solution Approach 1:
The cleaning device is segmented into distinct functional components: a cable or rod for delivery, a patch for cleaning, and a grip mechanism with arbor and plug for secure attachment. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity.
Solution Approach 2:
The grip mechanism acts as an intermediary between the cable/rod and the cleaning patch, providing a secure connection that prevents the patch from becoming stuck while allowing effective force transmission during the cleaning process.
2Productivity
If conventional cleaning devices are used, then assembly is simple, but assembly time is excessive in field use scenarios
Solution Approach 1:
The grip mechanism is pre-assembled with the arbor and plug components ready for quick attachment to the cable or rod. The longitudinal slot in the plug allows for rapid insertion and securing of the arbor without requiring complex assembly steps.
Solution Approach 2:
The plug incorporates a longitudinal slot that allows dynamic adjustment and quick securing of the arbor, enabling rapid assembly and disassembly of the cleaning device in field conditions.
3Reliability
If the cleaning patch is securely gripped, then cleaning effectiveness improves, but the risk of the patch becoming stuck increases
Solution Approach 1:
The grip mechanism applies localized pressure through the arbor and plug assembly specifically at the patch attachment points, providing secure grip only where needed while maintaining flexibility elsewhere to prevent sticking.
Solution Approach 2:
The cleaning patch itself is a flexible element that can deform to navigate barrel contours, while the grip mechanism maintains secure attachment through the flexible cable or rod that can bend and adapt to the barrel shape.
4Manufacturing precision
If the plug rotates inadvertently on the arbor, then cleaning precision deteriorates, but the assembly becomes simpler
Solution Approach 1:
The plug and arbor features are designed with asymmetric geometries that provide directional engagement, preventing inadvertent rotation while maintaining a relatively simple overall connection structure.

AI summary
A novel cleaning patch system comprising a novel patch grip for cleaning firearm barrels is disclosed. A patch grip includes an arbor and a plug. The arbor includes a base, a stem extending from the base, and an elongate crest connected to the stem. The plug includes an elongate passage therethrough that generally matches the dimensions of the elongate crest. The plug further comprises relatively recessed and/or protruding structures on the face of the plug adjacent the elongate passage that engage the crest of the arbor and prevent inadvertent rotation of the plug on the arbor during firearm cleaning.
