Blasting Cartridges TRIZ Cases
- Projectile Launching Device Buffer Member Shock Wave Modification
Buffer member modifies detonation shock wave to propel flyer, preventing spalling from high tensile stresses.
- Autonomous Pyrotechnic Igniter Simulator
An autonomous pyrotechnic igniter simulator replaces complex validation hardware by using a microcontroller to dynamically switch an impedance block.
- Rock Cracker Cartridge Deflagration Ignition Safety
Deflagration ignition eliminates detonation risks in rock cracker cartridges, enabling safe transportation and handling.
- Detonation System Sealed Initiation Assembly
A detonation system uses a dart to seal the tandem sub and protect internal electronics from wellbore fluids.
- Modular Pyrotechnic Igniter with Grooved Pins
Grooved conductive pins join flexible plastic cells, resolving manufacturing cost and modularity trade-offs.
- Energetic Material Initiation Device Switch Timing
Switch closes within 5 microseconds of detonation to intercept excess current, preventing electrical overload on the housing assembly.
- Reusable Tandem Sub With Signal Bar for Perforating Gun Pressure Isolation
Mold material injected into the annulus seals and insulates the signal bar, isolating pressure between perforating guns while ensuring reliable detonation.
- Bridged Bulkhead Assembly for Perforating Gun Signal Isolation
A bridged bulkhead assembly connects signal and detonator pins to secure electrical connections within a perforating gun.
- Electric Igniter Pin Identification via Impedance Measurement
Impedance measurement identifies pin polarity to eliminate costly X-ray projection and prevent electrode misconnection.
- Booster Cartridge Vents and Flexible Bag for Detonation Efficiency
Vents in the floor allow air and water evacuation during insertion, preventing misfires caused by trapped fluids in water-filled boreholes.
