Solution Overview

Problem

Existing firearm cleaning tools are not compact enough for easy storage, transportation, and use in various settings, despite their effectiveness in cleaning applications.

Innovation Solution

A compact T-handle firearm cleaning tool with a T-handle and cavity design that incorporates a flexible cable and rod system, featuring a tapered cavity to securely hold cleaning tips and a threaded rod for versatile use, allowing for easy assembly and disassembly of cleaning bits and tips.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If existing firearm cleaning tools are designed with traditional structures, then they achieve effective cleaning functionality, but they become too large for compact storage and transportation

Engineering Contradiction:
Improvetool sizeVSAvoidstorage and transportation convenience
Core Design Contradiction:
Volume of moving objectVSAdaptability or versatility

Solution Approach 1:

The cleaning tool employs a nested structure where the cable stores within the T-handle body, and cleaning tips attach to the cable. The T-handle serves as the outer container, the cable as the middle layer, and cleaning tips as the innermost elements, achieving compact storage while maintaining full functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The cleaning tool is divided into separate functional modules: a T-handle body with cavity, a flexible cable, and interchangeable cleaning tips. These segments can be stored separately or assembled together, providing versatility for both compact storage and full cleaning operation.

Inventive Principle:
Principle #1Segmentation

2Volume of moving object

If the cleaning tool is made compact with a T-handle and cavity design, then storage and transportation become easier, but the complexity of assembling and disassembling cleaning bits increases

Engineering Contradiction:
Improvetool sizeVSAvoidassembly and disassembly complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The cleaning tool employs dynamic assembly where the cable can be inserted and removed from the T-handle cavity, and cleaning tips can be attached and detached from the cable. This dynamic design allows for simple assembly and disassembly operations while maintaining a compact stored configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cleaning tips are extracted as separate interchangeable components that can be easily removed from the cable and replaced with different tips. This extraction design simplifies the assembly process by allowing users to attach only the specific cleaning tip needed for the current task.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If a flexible cable system is used instead of rigid rods, then the tool becomes more versatile for different cleaning applications, but the structural stability may be reduced

Engineering Contradiction:
Improvecleaning application versatilityVSAvoidstructural stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The cleaning tool uses a flexible cable instead of rigid rods, allowing the cable to bend and conform to different barrel configurations. The flexibility enables the cable to reach various cleaning positions while the T-handle provides stable anchoring points.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The rigid T-handle body acts as a counterbalance to the flexible cable, providing structural stability and anchoring. The T-handle's solid construction compensates for the cable's flexibility, ensuring the cleaning tool maintains stability during operation.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

AI summary

A firearm cleaning tool includes a T-handle having a T-handle longitudinal axis and an outer T-handle surface. A cavity has a cavity longitudinal axis. The cavity is disposed in the T-handle about transverse to the T-handle longitudinal axis. The cavity is opened at least in part through the outer T-handle surface along the cavity longitudinal axis. A ledge disposed within the cavity is adapted to capture a fitting of a cable.
