Drilling Rods TRIZ Cases

Coupling portions integrate conductive rings and insulating seal bodies to link composite pipe segments.

A downhole joint assembly manages fluid flow between primary and secondary paths using transport conduits.

An adjustable damper changes transverse size to reduce friction during assembly.

Helical bristles trap solids during rotation, preventing pump reentry and reducing wear while centralizing rods to avoid tubing friction.

A spring-biased locking pin couples inner and outer mule shoe assemblies in directional drilling tools.

A threadless float assembly secures a valve using a packer lock ring and spacer to enable standard casing mating.

Metal reinforcing members bridge plastic housing junctions while elastic isolators absorb impact energy, preventing cracking and protecting internal components.

Running tool fills auxiliary lines during installation to prevent seawater pressure damage.

A subsea wiring splice uses isolating material to surround conductors and block fluid ingress within a compact housing.

An axial rotary interface reduces hoop stresses in a toroidal fluid swivel, enabling larger diameters without excessive wall thickness.

An anchor system clamps around an oscillating pumpjack rod to abrade its surface and maintain a wellhead seal.

Composite adhesive bonding with wave-shaped end fittings eliminates stress concentration in fiberglass sucker rod strings, preventing premature failure.

Merges hydraulic catwalk and power swivel onto one trailer to eliminate separate equipment setups, reducing rig site space usage and operational costs.

Movable gate and locking pin secure hoses in bracket assembly, preventing oscillation and rupture during turbulent conditions.

A tubular connection system estimates remaining turns to target torque for precise threaded assembly.

Integrated blowout preventer combines deployment and pressure containment functions using multi-ram assemblies for compact wellhead installation.

Integrated heave compensation system synchronizes vertically mobile working deck and top drive carrier, reducing wellbore pressure variations.

Radial pivoting of anchor members stabilizes cutting tools in vertical casing, resolving positioning instability during severing operations.

A pivotable diving board assembly absorbs impact loads through angular rotation.

An inflatable support device seals wellbores using a selectively connectable element and burst prevention sheath.

A double housing structure combines an internal resin portion with an external metal shell to support power tool drive units.

Cold spray deposition bonds solid powder particles onto downhole motor rotors to form durable protective layers without melting the coating material.

Segmented perforating guns anchor sequentially to the wellbore wall, enabling longer strings without surface space constraints.

A double shoulder tool joint uses guard portions to protect sealing surfaces from damage during make-up operations.

A tubular protector assembly uses carbon fiber tape and a cellular steel cage to protect drill strings.

Segmented wet mate connectors isolate pump retrieval from permanent power cables, preventing mechanical wear on electrical components during maintenance.
