Shotgun Ammunition TRIZ Cases

A nested .410 hull in a .45-70 cartridge base improves feeding and accuracy, letting one rifle handle both small and large game.

Alternating roll and tapered crimps secure multiple wadcutter projectiles for controlled spread and reliable cycling in semi-automatic firearms.

PBS copolymer and stearate salt improve injection-molding flow and firing durability while enabling shotgun wads to biodegrade within six months.

A polybutylene succinate and calcium carbonate wad balances biodegradability with moisture resistance for more consistent cartridge ballistics.

Polyhydroxyalkanoate polymer wads degrade quickly in water, resolving the trade-off between shot accuracy and environmental harm.

Scored petal segments expand after barrel exit, resolving shot pattern degradation from cup separation.

Movable wad base expands against barrel bore to stop gas pressure loss and boost kinetic energy.

A shot casing configuration arranges first shots into pentagonal rings with second shots filling central interstices.

A firearm barrel cleaning cartridge uses a flexible textile cup to contain particulate obturating media for effective interior scrubbing.

A water-soluble and compostable plastic wad maintains mechanical strength through controlled moisture content.

Resilient retaining tabs flex outward to release artillery grenades while returning to equilibrium for secure retention.

Wax-impregnated cellulosic fiber wads maintain ballistic reliability while ensuring environmental sustainability through biodegradability.

A frameless ballistic cleaning pad deforms radially under propellant force, eliminating rigid frame energy loss for thorough bore cleaning.

Segmented inner linings in a choked shotgun shell restrict the opening diameter to produce tighter pellet grouping without requiring specialized barrels.

A rimless shotshell hull design ensures reliable ammunition feeding through a standardized cylindrical side surface and seat surface configuration.

Segmenting payloads with an intermediary separator prevents chamber pressure spikes while maintaining versatile downrange delivery.

Variable stroke speed control via eccentric or cam assemblies optimizes precision during critical phases while maintaining high production rates.

Segmented polymeric base wad diaphragm breaks to control triggering flame intensity, resolving incomplete ignition dynamics and improving ballistic performance.

Dynamic fin deployment stabilizes the shotshell wad during flight, resolving yaw instability caused by ported chokes.

A handheld payload launcher offsets recoil using a firing pin striking an object and nested barrel components for compact transport.

Front-positioned shot and a rear slug share one shotshell load, resolving the trade-off between target coverage and penetration power.

Radial fins on the biodegradable obturator expand under pressure to compensate for material degradation and prevent gas leakage.

An elastic ring within the case retains the wad, preventing trajectory alteration and environmental pollution.

Rounded cubic shot achieves 8% higher packing density than spheres by applying curvature to edges, resolving flow issues in metering devices.

A biodegradable shotgun wad uses fibrous materials to maintain structural integrity during firing.

A spherical warhead uses a cylindrical support to stabilize flight trajectory.

A shotgun inner chamber uses radial vents to release gas behind the wad, decelerating it before muzzle exit.

A shotgun shell uses a snap-fit detachable cap and injection port to swap projectiles, resolving the trade-off between adaptability and device complexity.
