Snap Cap with Corrosion Inhibitor Molecules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snap caps, especially those made of metal, can contribute to or fail to prevent corrosion, rust, and tarnish within firearms and their components, which are typically made of metal.
Innovation Solution
The development of snap cap devices that incorporate a protective material capable of releasing corrosion protection molecules, such as volatile corrosion inhibitors (VCIs) or vapor phase inhibitors (VPIs), to inhibit or prevent corrosion, rust, and tarnish within firearms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional metal snap caps are used, then the snap cap provides structural durability and functionality, but it causes corrosion, rust, and tarnish to firearm components
Solution Approach 1:
A non-metallic snap cap body is used as an intermediary to prevent direct metal-to-metal contact between the snap cap and firearm components. This eliminates the galvanic corrosion pathway while maintaining the structural functionality needed for dry-firing protection.
Solution Approach 2:
The snap cap employs composite construction with a non-metallic body material (such as polymer or composite resin) combined with metallic components only where absolutely necessary. This composite approach provides structural durability while minimizing corrosion risk by reducing metal content and isolating metallic parts from direct contact with firearm components.
2Ease of manufacture
If metal snap caps are used, then the snap cap can be easily manufactured with appropriate strength, but it fails to protect against corrosion and tarnish
Solution Approach 1:
The non-metallic snap cap body is designed as a disposable or periodically replaceable component. This allows manufacturers to use simple, cost-effective molding processes for the polymer body while users replace the snap cap periodically, eliminating the need for complex corrosion protection systems and ensuring reliable protection without complicated manufacturing.
3Reliability
If a protective coating is applied to metal snap caps, then corrosion protection is improved, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
Rather than applying complex protective coatings to metal snap caps, the invention uses a completely non-metallic body that is disposable or periodically replaceable. This eliminates the need for corrosion protection coatings entirely, simplifying both manufacturing and device structure while maintaining reliable corrosion protection through material selection.
