Angled Breech Cleaning Tool with Composite Scraping Head
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rifle breech chamber cleaning tools are inefficient due to wear-prone steel bristles, incomplete debris removal, and the need for extension rods, which complicate access and safety during cleaning.
Innovation Solution
A hand-held breech chamber cleaning tool with an angled bar forming a handle and scraping head, allowing direct side access to the breech chamber, eliminating the need for extension rods and providing improved pressure and feedback for effective cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If steel bristles are used to clean the breech chamber, then the cleaning action is provided, but the bristles wear quickly reducing reliability
Solution Approach 1:
The patent changes the material parameter from steel bristles to a combination of nylon bristles and wire brush elements. The nylon bristles provide gentle cleaning while the wire brush elements provide aggressive cleaning where needed. This material parameter change resolves the contradiction by providing durable cleaning elements that do not wear as quickly as steel bristles alone.
Solution Approach 2:
The cleaning tool head uses composite materials combining nylon bristles and wire brush elements in a single head assembly. This composite approach allows different material properties to be utilized in different regions of the cleaning head, achieving both durability and effective cleaning without the rapid wear problem of steel bristles.
2Length of moving object
If extension rod is used to access the breech chamber, then the reach is extended, but the device complexity increases
Solution Approach 1:
Instead of extending the tool forward through the bore to reach the breech chamber (conventional approach), the patent inverts the approach by accessing the breech chamber from the rear end of the rifle. The cleaning tool is inserted through the ejection port or breech opening directly, eliminating the need for long extension rods and complex threading mechanisms.
Solution Approach 2:
The patent extracts the extension rod component from the cleaning tool design by accessing the breech chamber directly from the rear. This extraction simplifies the device complexity while maintaining the ability to reach and clean the breech chamber effectively.
3Quantity of substance
If steel bristles are used for cleaning, then the cleaning coverage is provided, but the cleaning completeness is insufficient leaving debris
Solution Approach 1:
The cleaning head is segmented into different functional zones: nylon bristle sections for general cleaning coverage and wire brush sections for aggressive debris removal from hard-to-reach areas. This segmentation allows each material to perform its optimal function, achieving both comprehensive coverage and complete debris removal.
Solution Approach 2:
The composite structure of the cleaning head combines nylon bristles and wire brush elements to achieve both broad cleaning coverage and effective debris removal. The nylon bristles cover large areas gently while the wire elements tackle stubborn debris, resolving the contradiction between coverage and completeness.
4Ease of operation
If finger is used to clean the breech chamber, then the direct access is provided, but the safety risk and contamination increases
Solution Approach 1:
The patent introduces a specialized cleaning tool as an intermediary between the operator and the breech chamber. This tool provides direct manual access for cleaning while eliminating the safety risks and contamination problems associated with using bare fingers. The tool acts as a mediator that protects the operator while enabling effective cleaning.
