Time Fuzes TRIZ Cases
- Dual-Mode Aerial Fuzing for In-Flight Target Adaptation
A remotely selectable proximity-or-impact fuze lets one aerial munition adapt in flight to soft or hard targets before release.
- Inertial Igniter Delay Mechanism for Low-G Firing Detection
A spring-loaded striker and mechanical delay mechanism enable compact inertial ignition under low-g, long-duration firing while resisting accidental shocks.
- Bomb Fuze Initiator With Integrated HF/IR Proximity Sensing
An HF or infrared transceiver integrates with the bomb fuze initiator to sense ground distance without separate proximity-sensor hardware.
- Remote Initiator With Accelerometer Detonation and RF Pairing
An accelerometer-triggered remote initiator uses pre-pairing and secure RF commands for controlled stand-off detonation in challenging conditions.
- Autonomous Safety Control Actuation Using Kalman-Lyapunov Prediction
A sensor, Kalman filter, Lyapunov function, and comparator predict threshold approaches for timely safety control actuation.
- Spring-Driven Inertial Igniters for Low-G, Long-Duration Firing
Preloaded springs help compact inertial igniters detect low-G firing without drop activation.
- Dissolvable Firing Head Retention Mechanism for Perforating Guns
A degradable retention mechanism chemically reacts with well fluid to free a firing pin and strike a percussion detonator.
- Gun-to-Gun Detonation Transfer Delay Fuse for Perforating Guns
Replacing electrical connections with mechanical impact ignition and sequential delay fuses resolves signal transmission complexity in well perforation.
- Purely Pyrotechnic Hand Grenade Fuze System Design
Dual pyrotechnic delay elements trigger gas pressure to open shut-off valves for detonator activation.
- Safety Ignition Device for High Altitude Dual Pulse Motor
A compact safety ignition device integrates primary and secondary circuit units within a single housing to ensure reliable ignition signals.
- Dual Centrifugal Lock Self-Destruct Impact Fuze
Segmenting the mechanism into two independent locks balances rotational forces, preventing premature arming and ensuring safe self-destruction.
- Ammunition Deconfinement Device for Safe Explosive Neutralization
Controllable deconfinement device releases explosive charge via pressure or temperature activation, preventing unintended detonation and collateral damage.
- Eddy Current Muzzle Velocity Sensor for Airburst Munitions
Mn-Zn ferrite cores generate eddy current signals to calculate flight speed, reducing power consumption and magnetic interference.

A pyrotechnic delay device uses a bypass element with a high-burning-rate transfer charge to enable adjustable timing within a single unit.
- Projectile Safe-and-Arm Device Unbalanced Rotor Mechanism
Centrifugal force drives an unbalanced rotor to retract a lockpin, arming the projectile only after second-stage ignition.
- Self-Destruction Mechanism for Fuze
A mechanical self-destruction device uses a setback body and locking pin to secure components during acceleration.
- Projectile Fuse Speed Sensor Safety Logic
Independent speed sensors prevent accidental detonation by verifying motion before timer activation.
- Flexible Tongue Time Control for Micro-Machined Counterweight Delay
Elastic tongues replace zigzag mechanisms to ensure reproducible delay times without increasing device complexity.
- Ballistic Transfer Delay Device for Wellbore Perforation
Replacing hydraulic systems with a ballistic train eliminates pressure leak risks while ensuring precise multi-zone wellbore perforation timing.
- Reversible Safety Arming System with Mechanical Chronometric Module
A reversible safety and arming system uses a mechanical chronometric module to wind a spring via a pinion, enabling automatic return to a safe position.
- Hydraulic Delay Sub for Perforating Guns
A hydraulic delay sub meters fluid through a JEVA orifice to time perforating gun activation, eliminating pyrotechnic safety hazards.
