Solution Overview

Problem

Existing gun barrel cleaner rods are inconvenient to store and transport due to their elongated shape, and the connections are prone to breaking, leading to a short service life and increased costs.

Innovation Solution

A gun barrel cleaner rod system comprising detachable cleaner rods connected via a stud bolt with a non-threaded portion and smoothing surfaces to prevent deformation and breakage, allowing for rapid assembly and improved strength.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a threaded connector is used to connect cleaner rods, then storage and transportation convenience is improved, but the connection strength deteriorates and breakage occurs

Engineering Contradiction:

Improvestorage and transportation convenienceVSAvoidconnection strength

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The cleaner rod is divided into multiple detachable segments that can be separated for storage and reassembled for use. Each segment has standardized connection interfaces that allow quick assembly while maintaining structural integrity during operation.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The connection structure uses composite design combining threaded portions for assembly with smooth transition portions for stress distribution. The interface integrates multiple material properties to prevent breakage while enabling easy connection and disconnection.

Inventive Principle:

Principle #40Composite materials

2Volume of moving object

If multiple short rods are connected to form a long cleaner rod, then storage and transportation efficiency is improved, but the service life deteriorates due to breakage at connecting positions

Engineering Contradiction:

Improvestorage spaceVSAvoidservice life

Core Design Contradiction:

Volume of moving objectVSDuration of action of stationary object

Solution Approach 1:

The connection interfaces are pre-designed with stress distribution features and transition surfaces that prevent stress concentration before actual use. The smooth portions are formed in advance to distribute mechanical loads evenly during assembly and operation, preventing premature failure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The connection structure incorporates stress-absorbing transition zones that cushion mechanical loads before they reach the threaded connection points. This protective design prevents stress concentration and breakage, extending the service life of the assembled cleaner rod.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

AI summary

A gun barrel cleaner rod includes a first cleaner rod and a second cleaner rod. The first cleaner rod and the second cleaner rod are detachably connected. A first lower end of the first cleaner rod and a second upper end of the second cleaner rod are detachably connected through a stud bolt. The stud bolt includes a first threaded end and a second threaded end. The first lower end of the first cleaner rod includes an upper thread, where the upper thread is matched with the first threaded end, and the second upper end of the second cleaner rod includes a lower thread, where the lower thread is matched with the second threaded end. The gun barrel cleaner rod achieves rapid connection through cooperation of stud bolts and a plurality of short rods, which saves storage space, transportation space, and cost.
