Pyrotechnical Actuators TRIZ Cases

An internal gas generator and plug-like support member seal the housing opening while keeping the power connector outside for simpler assembly.

Interchangeable pistons and spacers tune gas chamber volume, letting one vehicle actuator housing deliver different force, speed, and stroke.

A pressure surge drives the locking unit into the housing, enabling compact high-force decoupling of loaded vehicle seat connections.

A sleeve-reinforced plastic piston-pin boosts radial strength and stiffness in pyrotechnic actuators without the cost of a full metal part.

A break-point propellant housing tears off on ignition to drive the piston and seal gas pressure without O-rings or extra parts.

An external gas generator on the piston support makes ECU wiring easier in tight vehicle spaces while avoiding costly integrated harnesses.

A folded piston rod limits stroke and gently brakes hood-lift actuators while simplifying sealing and avoiding housing damage.

A self-retaining locking ring stops hood actuator retraction after pedestrian impact, keeping the hood elevated with simple geometry.

A crimping interface holds the piston securely at rest, cutting tolerance-driven cost while preventing rattling and accidental detachment.

A three-conductor pyrotechnic switch cuts opening force and size while improving high-current arc interruption with resilient support and gas action.

A segmented three-conductor switch uses a breakable retainer and arc extinguishing media to cut actuator size and cost in high-current opening.

An explosive expansion vessel separates the conductor without a piston, cutting arcing, gas leakage, and delay in high-current circuit disconnection.

A sleeve-reinforced plastic piston-pin structure raises radial force resistance in pyrotechnic actuators without the cost of full-metal parts.

An offset actuator and elongated container make parachute ejection easier to package and mount at more UAV positions with lower drag.

An off-center actuator and separate parachute housings improve ejected-object accommodation and allow more aircraft mounting positions.

Variable gas-flow damping smooths pyrotechnic driving force from startup to in-place locking, reducing impact, overload, and mechanical stress.

Telescopic actuators driven by gas generators or shape memory materials force open jammed armored hatches for rapid evacuation.

A pneumatic gasket actuator uses pyrotechnic gas and compact deployment to open reinforced doors and hatches quickly in tight spaces.

A throttled dual-volume pneumatic actuator enables fast chamber opening with reliable sealing and precise ignition control at high pressure.

Pyrotechnic gas pressure drives a piston-cylinder latch release for fast wing retraction, reducing aircraft storage size and handling risk.

A sear pin, piston, and spring let one actuator deliver the same firing output from either mechanical force or fluid pressure.

A modular explosive piston assembly delivers repeatable instant force for pushing, flipping, or rolling objects across varied mounting setups.

A dual-volume pneumatic actuator uses unequal piston areas and a throttle to open an explosion chamber quickly under extreme pressure and heat.

A spring-precharged piston accumulator uses heating to maintain subsea hydraulic pressure, avoid gas recharge issues, and deliver full fluid volume.

Dual axial venting connections rapidly clear pre-chamber gases, cutting backpressure and improving piston drive in combustion setting tools.

Combustible gas ignition in a microscale chamber drives a membrane actuator without external pumps, enabling compact high-density actuation.

Axially spaced pre-chamber vents speed exhaust discharge, cut counter-pressure, and prevent gas backflow in fuel-operated firing devices.

Pressurized gas automatically decouples the normal drive and extends the actuator to a locked emergency position without separate backup hardware.

Pressurized gas decouples the drive during failure, allowing emergency extension and mechanical locking without separate backup hardware.

A pyrotechnic body panel lifter uses balls on a tapered ramp to generate controlled retraction force.

Screws connect housing parts and fix the conductor through pre-drilled holes, eliminating separate fasteners.

A vented pressurized gas actuator uses geometric vent grooves to manage internal gas flow and adjust the mechanical force exerted during piston movement.

A preloaded closure cap positions the piston and seals the cylinder, preventing wobbling and rattling noises while blocking moisture ingress.

A pyrotechnic actuator uses a breakable member and pressurized gas to move a piston within a housing.
