Gun Barrel Cleaning Device Hinged Latch Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for gun barrels require frequent disconnection and reconnection of cleaning tools, leading to time-consuming assembly and a risk of cross-threading damage, which can result in the cleaning device becoming lodged or unscrewed during use.
Innovation Solution
A hinged latch interface system between the cleaning rod or cable and devices, featuring an engagement recess and channel with a hinged latch that securely attaches and detaches with a pushing and pulling motion, allowing for easy change between cleaning tools without unintended disconnection, and fabricated using reinforced plastic for durability and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If threaded interface is used to attach cleaning devices to cleaning rod, then cleaning devices can be securely attached, but assembly becomes time-consuming and susceptible to cross-threading damage
Solution Approach 1:
The cleaning device is divided into separate modular components (cleaning head, shaft, handle) that can be independently manufactured and assembled. The threaded interface segments the connection system into male and female threads, enabling standardized attachment while maintaining security.
Solution Approach 2:
The threaded interface acts as an intermediary mechanism between the cleaning device and cleaning rod. It provides a standardized mediation layer that enables secure attachment while reducing assembly time through threading rather than complex fastening procedures.
2Reliability
If threaded interface is used to attach cleaning devices, then secure connection is achieved, but risk of cross-threading damage increases
Solution Approach 1:
The threaded interface employs asymmetric thread geometry with specific pitch, angle, and profile characteristics. This asymmetry is designed to guide proper alignment during assembly while preventing cross-threading through self-centering features and directional engagement of the thread flanks.
Solution Approach 2:
The threaded interface design incorporates built-in protection against cross-threading damage before it can occur. Features such as thread run-out zones, alignment guides, and tolerant thread profiles provide a cushioning effect that prevents damage even if minor misalignment occurs during assembly.
3Productivity
If cleaning device is pushed through barrel assembly, then effective cleaning is achieved, but unintended disconnection may occur with threaded interface
Solution Approach 1:
The threaded interface is pre-assembled and pre-tightened before the cleaning device is inserted into the barrel assembly. This preliminary action ensures that the connection is already secured and locked in place, preventing unintended disconnection during the pushing motion required for effective cleaning.
Solution Approach 2:
The pushing force that could potentially cause disconnection is converted into a beneficial tightening force. The threaded interface design allows the axial pushing force to further engage and secure the threaded connection, transforming a potential harmful effect into a benefit that enhances connection stability during cleaning operation.

AI summary
The present invention is an improvement to a gun barrel cleaning tool which enables a user to attach and remove gun barrel cleaning devices to a gun barrel cleaning rod by inserting a cleaning device into a recess formed in the cleaning rod whereupon a latch located in the recess engages a recess of the cleaning device to secure the cleaning device to the barrel cleaning rod.
