Barrels TRIZ Cases
- Barrel Chamber Machining Using Bore-Probed CNC Alignment
Automated bore probing lets a CNC machine cut rifle barrel chambers with high concentricity, less setup time, and fewer specialized reamers.
- Gun Barrel CNC Milling with Keyed Rib Fixturing
A keyed billet and rib-based fixturing keep gun barrels aligned through 5-axis CNC milling, cutting handling and machining time.
- Gun Barrel Milling with Keyed Clamping for Faster Alignment
A keyed billet held in one 5-axis setup cuts gun barrel machining time and avoids misalignment from repeated loading.
- Asymmetric Barrel Gas Port Geometry for Projectile-Safe Gas Extraction
An elongated barrel gas port entrance reduces projectile contact, preserving shooting accuracy and slowing barrel wear during gas extraction.
- Carbon Fiber Rifle Barrel Preload for Higher Rigidity and Accuracy
A heated barrel core is cured inside a carbon fiber shell to lock in tension, cutting weight while boosting rigidity and shot accuracy.
- Spin-Stabilized Net Projectile for Accurate UAV Capture
Rifled spin ejects and expands a packed net, improving launch stability, range, and repeatable UAV capture with a lighter, simpler projectile.
- Rotary Gun Suppressor Core for Flash and Shock Wave Reduction
Symmetric suppression tubes and a gas redirector cool and redirect propellant flow to cut rotary gun noise, flash, and shock waves.
- Asymmetric Rifling in Firearm Barrels to Reduce Gas Blow-By
Asymmetric land profiles in firearm barrels redirect gas flow to reduce blow-by, erosion, and accuracy loss during firing.
- Flatform Barrel Rifling for Accuracy and Barrel Life
Alternating arcuate and linear rifling portions reduce engraving and friction while preserving projectile stability and barrel life.
- Multi-Chamber Suppressor with Isolated Blast Chambers for Rotary Guns
Isolated blast chambers keep cartridge gas out of non-firing barrels, limiting fouling and heat transfer while extending component life.
- Composite-Wrapped Lightweight Firearm Barrel With Heat-Treatment Sequencing
The barrel process fixes chamber depth before heat treatment, then adds composite wrapping for lower weight and longer life.
- Composite-Wrapped Firearm Barrel with Pre-Heat-Treatment Chamber Machining
The chamber is machined to final depth before heat treatment, then composite wrapping reduces weight without heat damage.
- Hybrid Carbon-Steel Firearm Barrel Thermal Management
A woven stainless steel mesh layer inside a carbon fiber composite sleeve conducts heat lengthwise, reducing barrel weight by 50% while maintaining stiffness.
- Concentric Rifle Barrel Assembly with Segmented Sleeve
Segmented design prevents headspace wear during caliber swaps while fluting reduces weight and improves heat dissipation.
- Lightweight Composite Mortar Tube Thermal Management
Ceramic matrix liner and metal overwrap resist overheating during continuous firing to preserve mortar durability.
- Variable Twist Rifling for Gun Barrel Piezometric Efficiency
Variable twist rifling resolves chamber survivability constraints by modulating torque spikes and pressure relief zones to maximize propellant work.
- Hybrid Composite Projectile Barrel Locking Features
Ribs and pins distribute thermal stress at transition regions to prevent interface fracture.
- Firearm Barrel Grooved Gas-Venting Pattern Reduces Bullet Velocity
Longitudinal grooves merge with rifling to vent expanding gases, lowering internal pressure and achieving subsonic speeds without specialized ammunition.
- Double Barrel Adjustment Assembly for Angular Orientation
Rotatable adjustment members enable precise angular orientation of firearm barrels without modifying external surfaces.
- Sub-Sonic Firearm Barrel Shallow Rifling for Trajectory Precision
Multiple shallow rifling grooves reduce buffeting effects from shock waves on bullet lands, ensuring consistent impact points.
- Composite Firearm Barrel with Perforated Steel Core
Perforated steel cores in composite barrels distribute combustion forces evenly, reducing weight without sacrificing accuracy or heat dissipation.
- Rifled Barrel Manufacturing via External Die Indentation
Integrating rifling formation into the extrusion process eliminates costly secondary operations and enables production of small caliber barrels.
- Over-moulded Sporting Rifle Sound Suppressor Design
A sporting rifle integrates a sound suppressor via over-moulded material around the barrel.
- Interchangeable Pistol Barrel System Using Segmented Steel and Aluminum Components
A segmented pistol barrel system combines a steel insert with an aluminum receiver to enable caliber swapping.
