Breech Mechanisms TRIZ Cases
- Hybrid Metal-Polymer Pistol Frame with Interchangeable Inserts
A hybrid pistol frame integrates metal inserts into a polymeric housing to reinforce structural components.
- Convertible Gas Piston Assembly for AR-15 and AR-10 Rifles
A convertible gas piston assembly uses a dual-bore gas block to support AR-15 and AR-10 rifle platforms with interchangeable operating rod segments.
- Firearm Bedding Block Cam Surface Rigidity
Cam surfaces convert linear recoil into rotational moments, maintaining alignment while absorbing firing forces.
- Bolt Carrier Group Cam Path and Gas Port Optimization
Optimized gas ports and cam geometry reduce fouling and friction, improving cycling reliability in adverse conditions.
- Receiver Cover with Dual Locking Mechanism for Accessory Rail
A receiver cover integrates a tactical accessory rail and dual locking mechanisms to secure the unit to rifle components.
- Firearm Handguard Rail Alignment via Interlocking Key
An interlocking handguard key prevents circumferential rotation and eliminates manual alignment time.
- Compact Recoil Guide Device for Weapon Systems
Male bars on the cradle cooperate with female rails on the breech sleeve to reduce trunnion forces without adding heavy sleds.
- Mating Bolt Carrier and Barrel Extension Curved Recess Alignment
Curved recesses in the bolt carrier front face mate with angled barrel extension features to reduce bounce during firing.
- Ambidextrous Charging Handle for Firearms with Optical Sights
Segmented handles enable ambidextrous operation and optical sight compatibility without complex structures.
- Firearm Barrel and Breech Assembly with Dual-Level Locking
Dual locking geometries on the breech block absorb firing forces vertically, reducing weapon width while maintaining structural integrity.
- Adjustable Gas Block Assembly with Interchangeable Vent Plugs
Interchangeable vent plugs adjust gas flow through a firearm gas block assembly.
- Adjustable Bolt Lock for Single-Shot Firearm Operation
An adjustable bolt lock mechanism prevents automatic reloading by extending a bar to block bolt recoil during manual charging.
- Mid Lock-Up Receiver Sleeve Segmentation for Accuracy
A mid lock-up receiver uses a compressively fitted sleeve to form lug ways, creating a rigid structural interface.
- Pistol Slide Racking Assist Device Dovetail Mechanism
A pistol slide racking assist device connects an adaptor and rack plate via sliding dovetail joinery, reducing manual force required to pull the slide rearward.
- Collapsible Rifle Stock Shortening Without Bolt Carrier Replacement
A collapsible rifle stock design compresses the buffer tube assembly along its longitudinal axis to reduce overall length while maintaining standard bolt carrier group travel.
- Quick-Change Barrel Retaining System for Firearms
Spline-based locking mechanisms enable rapid barrel swapping while maintaining point of aim accuracy.
- Hinged Firearm Receiver Integrating Folding Stock
A hinged firearm receiver integrates a folding stock mechanism into the upper assembly to reduce overall length for storage.
