Tapered Gun-Cleaning Box Barrel for Muzzle Deflection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pistol clearing boxes suffer from muzzle deflection issues during gun-cleaning, leading to accidental injuries and operational inconvenience due to the design of the socket and the need for two-handed operation.
Innovation Solution
A gun-clearing box with a gun-placing barrel having a larger entrance diameter that gradually reduces to a smaller exit, featuring an inclined tapered gap between abutting surfaces in the sliding-sleeve assembly, allowing one-handed operation and guiding bullets into a buffer body to prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the socket diameter is made larger to accommodate the pistol, then the pistol can be easily inserted, but the muzzle deflection occurs and bullets are directed toward the side of the box-body causing accidental injuries
Solution Approach 1:
The patent applies local quality by creating a tapered structure within the socket where the diameter gradually decreases from the opening toward the bottom. This localized diameter variation allows the pistol to be easily inserted at the wider opening while the narrower lower portion guides and constrains the muzzle to prevent deflection, thus resolving the contradiction between ease of insertion and prevention of harmful deflection.
Solution Approach 2:
The patent introduces an intermediary structure - the tapered socket wall - that mediates between the pistol insertion process and the muzzle direction control. The gradual diameter reduction acts as a guiding intermediary that smoothly transitions the pistol into the correct position, preventing sudden deflection while maintaining ease of insertion.
2Reliability
If the user operates the pistol with both hands for gun-cleaning, then the control is more stable, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The patent applies self-service by designing the socket with a tapered structure that automatically guides and stabilizes the pistol muzzle during insertion. The tapered walls provide self-aligning guidance that maintains pistol control stability without requiring the user to use both hands, thus improving ease of operation while preserving reliability through the passive guiding mechanism.
3Object-affected harmful factors
If the socket diameter is reduced to prevent muzzle deflection, then the muzzle direction is controlled better, but the pistol insertion becomes difficult
Solution Approach 1:
The patent applies parameter changes by varying the socket diameter parameter along its length - larger at the opening for easy insertion, gradually reducing toward the bottom for muzzle control. This continuous parameter change resolves the contradiction by providing different diameter values at different positions to satisfy both requirements.
Solution Approach 2:
The patent uses a tapered (curved) diameter profile instead of a straight cylindrical socket. The gradual curvature of the diameter reduction provides a smooth transition that facilitates easy insertion while maintaining effective muzzle guidance, avoiding the abrupt constraints that would make insertion difficult.

A gun-clearing box, which has: a box-body having a gun-clearing space inside, a cover opening and an assembly opening connecting the gun-clearing space to the outside; a cover-body; a gun-placing barrel having an placing entrance, a shot exit, and a barrel wall connected between, such that the diameter of the placing entrance is larger than which of the shot exit; such that the gun-placing barrel is fixed in the assembly opening, and the placing entrance is faced toward the outside of the box-body, and the shot exit is inclined to face toward the gun-clearing space; and a sliding-sleeve abutting assembly set in the gun-placing barrel, such that the sliding-sleeve abutting assembly has two adjacent abutting surfaces with a gap between; such that the gap is inclined and reduced along the direction from the placing entrance to the shot exit; thereby improving the convenience and safety of the use.
