Breech Mechanisms TRIZ Cases
- Firearm Bolt Assembly with Pivoting Handle for Low-Force Extraction
A pivoting bolt handle uses leverage to reduce force during spent-cartridge extraction.
- Bearing-Delayed Firearm Operating Systems for Caliber Compatibility
This case shows how movable bearings delay bolt movement while supporting caliber compatibility and reducing reliance on venting holes.
- Hardened Cam Race with Riveted Pins for Upper Receiver Wear
A hardened steel or titanium cam race with riveted pins protects the upper receiver from cam-pin wear and supports reliable operation.
- Hand-Held Gun Breech Buffer Design for Compact Recoil Damping
A breech spring and compressible buffer body absorb recoil energy, reducing peak forces by up to 80% while preserving compactness.
- Gun Recoil Management Using a Spring-Mounted Inertial Weight
A tuned inertial weight and spring elongate the gun's recoil impulse, reducing peak force without relying on added gun weight alone.
- Subcompact Pistol Grip Protrusions for Stable Magazine Feeding
This pistol case uses localized grip protrusions to stabilize a higher-capacity magazine and reduce jamming and ejection issues.
- Blowback Firearm Breechblock Safety Lever for Out-of-Battery Protection
This case uses a lift pin and cam-driven lever to prevent discharge until the blowback breechblock is fully engaged.
- Repeating Rifle Mode Switching for Ergonomic Rapid Reloading
A two-stage switch combines fore-end and bolt-handle operation, addressing reload speed and ergonomic handling in repeating rifles.
- Firearm Recoil System Catch Mechanism for Easier Disassembly
A slide plug and plug retainer interfit to hold the recoil system partially compressed, simplifying removal and protecting components.
