Solution Overview

Problem

Conventional firearm cleaning rods are impractical for combat or remote hunting due to excessive length, weak handles, and inability to withstand environmental abuse, leading to issues with sand embedding, joint weakness, and difficulty in clearing critical bore obstructions without damaging the firearm.

Innovation Solution

A firearm maintenance tool with a rail mount segment and a rotatably mounted spindle to receive an elongated cleaning rod, featuring a square drive element for tool engagement, designed to provide a tool drive capability for forceful removal of obstructions while being compact and durable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If precision firearm cleaning rods are made of single piece steel or stainless steel, then the rod has sufficient strength to clear obstructions, but the excessive length and weak handle construction make them impractical to carry in combat

Engineering Contradiction:
Improverod strengthVSAvoidrod length
Core Design Contradiction:
StrengthVSLength of moving object

Solution Approach 1:

The cleaning rod is divided into multiple sections that can be assembled to the required length. Each section has standardized connection interfaces that provide mechanical strength while allowing the rod to be disassembled into compact segments for carrying in combat situations.

Inventive Principle:
Principle #1Segmentation

2Length of stationary object

If the cleaning rod is made longer to reach deep bore obstructions, then the rod can clear deeper obstructions, but the handle becomes weaker and more prone to breaking under abuse

Engineering Contradiction:
Improverod lengthVSAvoidhandle strength
Core Design Contradiction:
Length of stationary objectVSStrength

Solution Approach 1:

Instead of simply extending the rod length linearly, the design incorporates a multi-section construction with reinforced connection points. The handle is designed as a separate, reinforced component that can be securely attached to the rod sections, distributing mechanical stresses away from the handle and into the robust connection interfaces.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of operation

If commonly available sectional cleaning rods are used, then the rod can be carried in sections, but the section joints are weak and frequently break, causing pieces to become stuck in the bore

Engineering Contradiction:
ImproveportabilityVSAvoidjoint reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The connection interfaces between rod sections are designed with precise geometric parameters and tolerance specifications that create interference fits and mechanical interlocking features. This transforms the joint from a weak connection point into a reliable, strength-equal-to-or-greater-than-the-rod-itself connection, preventing breakage during use.

Inventive Principle:
Principle #35Parameter changes

4Ease of operation

If traditional cleaning rod handles are used, then the rod can be operated, but the handles cannot withstand forceful strikes needed to clear critical obstructions, potentially injuring the user

Engineering Contradiction:
ImproveoperabilityVSAvoidhandle strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The handle is pre-designed and pre-positioned as a separate, reinforced component that can be securely attached to the rod assembly. This preliminary preparation ensures that when forceful strikes are needed to clear critical obstructions, the handle is already in place and configured to absorb and distribute the impact forces, protecting the user from injury.

Inventive Principle:
Principle #10Preliminary action

AI summary

A firearm maintenance tool has a body including a rail mount segment and a spindle rotatably mounted to the body and adapted to receive an elongated cleaning rod. The tool may include a square drive element adapted to engage a tool socket. The body may be an elongated body, and the rail segment may extend the length of the body. The body may be an elongated body defining a body axis, and the spindle may extend perpendicularly from the body along a spindle axis perpendicular to the body axis. The body may define a first aperture receiving the spindle, and a second aperture receiving a retention element operably securing the spindle to the body. The first and second apertures may be perpendicular to each other.
