Gun Cleaning Tool Pull Handle via Removable Lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun cleaning devices face difficulties in smoothly pulling through gun barrels due to friction and resistance, and often become dirty, transferring debris to users' hands and clothes.
Innovation Solution
A gun cleaning apparatus with a storage case and removable lid that serves as a pull handle, allowing easy insertion and removal of the cleaning tool through the gun barrel, while containing the cleaning tool and debris within the case.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tubular sheath and brush are pulled through the gun barrel to clean it, then the gun barrel is cleaned effectively, but the cleaning tool becomes difficult to pull through due to friction and resistance
Solution Approach 1:
A pull cord is introduced as an intermediary element between the user and the cleaning tool. The pull cord extends through the entire length of the cleaning tool, allowing the user to pull the tool through the barrel without directly gripping the dirty cleaning elements. This mediator transfers the pulling force while keeping the user's hands clean and providing better control during the cleaning process.
2Productivity
If the cleaning tool is pulled through the gun barrel, then debris is removed from the barrel, but the cleaning tool becomes dirty and may transfer debris to the user's hands and clothes
Solution Approach 1:
The pull cord serves as a protective intermediary that separates the user from direct contact with contaminated surfaces. By threading the pull cord through the cleaning tool and gripping only the cord's handle portion, users can operate the cleaning tool without their hands touching the bristles, tubular sheath, or accumulated debris, thus preventing transfer of harmful contaminants to clothing and skin.
Solution Approach 2:
The cleaning tool is segmented into distinct functional zones: the cleaning section (bristles and tubular sheath) that contacts debris, the pull cord that transmits force, and the handle portion that interfaces with the user. This segmentation allows each component to perform its specific function while minimizing cross-contamination between clean and dirty areas.
3Ease of operation
If a loop of material is integrated into the tubular sheath to facilitate pulling, then ease of removal is improved, but the device complexity increases
Solution Approach 1:
The pull cord serves multiple functions simultaneously: it acts as a pulling mechanism for inserting and removing the cleaning tool from the barrel, serves as a handle for user grip, and can be used to control the depth of insertion. This multi-functionality eliminates the need for separate loops or handles, reducing structural complexity while maintaining ease of operation.

AI summary
A gun cleaning apparatus includes a cleaning tool and a storage case. The cleaning tool has a cleaning section and a pull cord having a distal end for pulling the cleaning section through a gun barrel. The storage case is configured for enclosing the cleaning tool. The storage case includes a substantially hollow container defining a rim at opening thereof, and a removable lid positionable between a closed configuration and an open position. The removable lid includes a handle section for gripping by a user to assist with pulling the cleaning tool through the gun barrel in the open configuration and configured to engage the rim in the closed configuration, and a connection section extending from the handle section, the connection section defining an elongate slot and a cavity for securing the distal end of the pull cord therein.
