Drilling Rods TRIZ Cases

Lateral offsets in the discharge device separate slurry and return flows, reducing erosion rates while preventing fluid communication between passages.

A load-bearing universal joint uses self-energizing seals to maintain sealing contact under rotational and axial loads.

A gooseneck conduit assembly uses a tenon and mortise interlock to secure the unit to a subsea riser tube.

A casing centralizer compression molded from mineral filled polyester resin.

Slots in the casing hanger seal extension reduce axial stiffness, redirecting upward forces away from the annular seal interface.

Rotating drive ring equipped with hydraulic gripping jaws and powered by an endless chain mechanism.

A universal rotating stripper adapter uses a 360-degree swivel ring to align with various tubing sizes.

A remotely controlled horizontal manifold connects kill and choke lines via a manipulator arm.

A telescopic filling pipe extends axially under liquid pressure to supply casing strings during assembly.

Mechanical swedging secures a degradable tubular sleeve against downhole apertures, preventing leaks until the material dissolves.

Radially expanding an expandable tubular via hydraulic pressure reduces borehole diameter requirements, lowering drilling costs and equipment complexity.

Segmenting the base tool from specialized adapters reduces manufacturing costs and inventory complexity while maintaining operational versatility.

Spaced antennas on a coupler carrier maintain signal integrity through threaded connections under high pressure.
