Firearm Locking System Hydrophobic Coating Fluid Drainage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearms locking systems become unreliable and inoperable when submerged in fluid, as fluid penetration prevents proper functioning of movable components, leading to malfunctions and requiring disassembly for cleaning.
Innovation Solution
Incorporating a locking system with fluid access openings or apertures that allow fluid to drain from the firearm's interior, ensuring the firing pin and other components can move unimpeded and fluid can be passively expelled, maintaining operability even after submersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the firearm is provided with a secured locking system using gas pressure loader, then the reliability during firing is improved, but the firearm becomes inoperable when submerged in fluid due to fluid penetration preventing movable components from moving
Solution Approach 1:
The patent applies hydrophobic coatings (thin films) to the interior surfaces of the firearm, particularly on the gas piston, gas rod, and chamber walls. These hydrophobic surfaces repel water and prevent fluid adhesion, allowing the firearm to operate reliably after submersion by preventing fluid from interfering with movable components' motion.
2Reliability
If gas propellant is directed through gas discharge to gas piston, then the loading mechanism reliability is improved, but residue build up occurs inside the firearm requiring frequent cleaning
Solution Approach 1:
Hydrophobic coatings are applied to the interior surfaces where propellant residue accumulates, including the chamber walls and gas piston surfaces. These coatings prevent residue adhesion and facilitate easy removal, reducing cleaning frequency while maintaining loading mechanism reliability.
Solution Approach 2:
The patent introduces an oxidizing agent delivery system that introduces oxygen or other oxidizing agents into the combustion chamber during or after firing. This accelerates the combustion of unburned propellant residues and prevents residue buildup on interior surfaces, maintaining reliability without frequent cleaning.
3Ease of operation
If the firearm is provided with fluid access openings to drain fluid, then the operability after submersion is improved, but the structural integrity may be compromised
Solution Approach 1:
Instead of adding physical openings that compromise structural integrity, the patent uses hydrophobic coatings on existing surfaces to create fluid-repelling properties. This maintains the firearm's structural strength while achieving fluid drainage and expulsion capabilities through surface chemistry rather than structural modification.

AI summary
Locking systems for use with firearms are described. An example locking system for use with a firearm includes a breechblock carrier and a lock spring mechanism that includes a piston. The breechblock carrier is configured to interaction with the piston. Additionally, the example locking system includes a first aperture. The piston is configured to expel fluid through the first aperture when the breechblock carrier retracts.
