Breech Mechanisms TRIZ Cases
- Practice Weapon Adapter for Tool-Free Barrel Conversion
A practice weapon adapter secures a fixed barrel to enable reliable operation with weakly charged ammunition.
- Handgun Grip Module Reinforcing Bracket for Recoil Distribution
Embedded metallic bracket distributes recoil forces across polymer grip module, resolving durability issues while maintaining compact lightweight design.
- Crowned Bolt Contour for Medium-Caliber Weapon Locking Mechanism
Large radius contours on bolts and breech heads shift maximum stress from edges to centers, reducing wear in medium-caliber weapons.
- Dual Spring Biasing Mechanism for Firearm Slide Cycling
Segmented springs lower manual effort and prevent injury while maintaining reliable automatic cycling.
- Charging Handle Exhaust Ventilation Gas Diversion
Integrated ventilation holes in the charging handle shaft channel exhaust gas down into the receiver, preventing harmful gas exposure to the user's face.
- Firearm Recoil Compensation via Internal Counterweight Linkage
Internal linkage synchronizes counterweight motion with breech travel, eliminating external rope drives that cause delay.
- Firearm Charging Handle Latch Pin Torque Reduction
A firearm charging handle latch mechanism transfers operational pressure via a stop surface, reducing torque on the pivot pin and preventing metal fatigue.
- Reinforced Magazine Feed Lips with Rear Actuated Bolt Hold Open
Segmenting the magazine top allows a follower projection to actuate a bolt catch without compromising the structural integrity of polymer feed lips.
- Lever Action Cartridge Rim Radial Gradient
A lever action cartridge rim features a radial gradient that lowers friction to prevent tubular magazine jams while maintaining extractor compatibility.
- Firearm Handguard and Barrel Assembly with Integrated Sound Suppressor
A unitary barrel suppressor assembly uses a radial gap for air cooling and an insulating handguard sleeve to manage thermal loads.
- Firearm Accessory Mount With Arc-Shaped Barrel Fixture
Ventilated mount with arc-shaped fixture allows rapid barrel replacement without losing accessory mounting options or causing overheating.
