Pyrotechnical Actuators TRIZ Cases
- Vehicle Safety Actuator Sealing With Integrated Power Connector
An internal gas generator and plug-like support member seal the housing opening while keeping the power connector outside for simpler assembly.
- Modular Vehicle Safety Actuator With Adjustable Gas Chamber Volume
Interchangeable pistons and spacers tune gas chamber volume, letting one vehicle actuator housing deliver different force, speed, and stroke.
- Pressure-Actuated Decoupling Module for Release Under Load
A pressure surge drives the locking unit into the housing, enabling compact high-force decoupling of loaded vehicle seat connections.
- Reinforced Plastic Piston-Pin Structure for Pyrotechnic Actuators
A sleeve-reinforced plastic piston-pin boosts radial strength and stiffness in pyrotechnic actuators without the cost of a full metal part.
- Pyrotechnic Actuator Housing Tear-Off Sealing Without O-Rings
A break-point propellant housing tears off on ignition to drive the piston and seal gas pressure without O-rings or extra parts.
- Vehicle Safety Actuator Layout for Accessible ECU Connection
An external gas generator on the piston support makes ECU wiring easier in tight vehicle spaces while avoiding costly integrated harnesses.
- Pyrotechnic Actuator Piston Rod Fold for Stroke Limiting
A folded piston rod limits stroke and gently brakes hood-lift actuators while simplifying sealing and avoiding housing damage.
- Hood Lifting Actuator Locking Ring to Prevent Impact Retraction
A self-retaining locking ring stops hood actuator retraction after pedestrian impact, keeping the hood elevated with simple geometry.
