Bullet-Shaped Rust Prevention Plug for Gun Barrel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rust prevention methods for guns, such as moisture-absorbing apparatus, have limitations in moisture removal and rust prevention due to a limited contact area between the moisture-absorbing material and the gun's interior, leading to inadequate protection against rust and potential safety hazards.
Innovation Solution
A rust prevention device comprising a mounting case and a bullet-shaped rust prevention plug made of porous adsorbents or volatile corrosion inhibitors mixed with adhesives, with a moisture-sensitive color-changing member and air channels, designed to increase the surface area contact with the gun's interior, enhancing rust protection and allowing for visual moisture detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If solid moisture absorbing material is enclosed in a sealed plastic container with limited perforations, then the material is protected from leakage, but the contact area between the material and air in the barrel is extremely limited resulting in poor moisture removal and rust prevention
Solution Approach 1:
The moisture absorbing material is divided into many small particles instead of being kept as bulk solid material. This segmentation increases the total surface area of the material that can contact moisture in the air, significantly improving moisture removal efficiency while the particles are contained within a perforated container structure
Solution Approach 2:
The container is designed with numerous small perforations distributed across its surface, creating a porous structure that allows air and moisture to penetrate through the container walls and reach the moisture absorbing particles inside. This porous design greatly increases the effective contact area between the moisture absorbing material and the gun barrel interior environment
2Reliability
If regular cleaning and oiling is performed to protect metal parts from rust, then rust prevention is achieved temporarily, but the maintenance process is complicated and requires frequent user intervention
Solution Approach 1:
The device enables self-service rust prevention by automatically absorbing moisture from the gun barrel interior through its moisture absorbing particles. The system protects the gun without requiring user intervention for cleaning or oiling, as the moisture absorption occurs passively and continuously whenever the gun is stored with the device in place
Solution Approach 2:
The moisture absorbing material is pre-positioned in the container and activated before the gun is stored. The device performs preliminary moisture absorption action, creating a protective environment against rust before any potential corrosion can occur, eliminating the need for reactive maintenance

AI summary
A rust prevention device for guns which includes a mounting case with a mounting space and a bullet-shaped rust prevention plug mounted in the mounting space is revealed. An outer diameter of the rust prevention plug is sized to fit in a bore or a magazine of the gun. A main body of the rust prevention plug which is a molded block made of porous adsorbents or volatile corrosion inhibitors (VCIs) is exposed outside the mounting case. Thereby the rust prevention device is loaded into the bore or magazine like a cartridge and the main body of the rust prevention plug is exposed to increase surface area in contact with air in the gun. The rust prevention plug has more contact with metal parts in the gun due to diffusion in air. Therefore, the gun is better protected against rust.
