Constructions TRIZ Cases

A compression spring and cam replace overstressed torsion springs so the flapper check valve closes reliably when flow stops, even against gravity.

Coaxial and helical gas streams clear dust and vapor from the laser path, enabling smoother, deeper wellbore rock tunnels.

Different roughness zones on an earth-boring cutting face steer formation chips, reducing balling and improving chip transport.

A debris-resistant equalizing passage balances pressure across a subsurface flapper before opening, reducing force and preventing valve damage.

Pressure is equalized before valve opening to cut actuation force, friction, and seal damage in high-differential wellbore valves.

A 2D fracturing model uses temperature- and pH-based fibre degradation data to improve proppant distribution and fracture conductivity.

3D quay sensing and ramp modeling help avoid obstacle collisions, reduce ship repositioning, and improve cargo ramp deployment safety.

A mechanical brake plate, pin, and spring linkage stops adjacent boarding bridge tunnels when extending or retracting wire ropes break.

A nested insertable safety valve restores borehole flapper sealing by latching into a damaged outer safety valve and using its control system.

Probabilistic neurosynaptic computing handles ambiguous oilfield data to generate recommendations and improve operational decisions.

A non-threaded spigot shank and curved transition reduce thread stress and bending fatigue while preserving shock wave transmission.

A pressure-setting valve redirects excess arm-line fluid to wheel motors, raising downhole tractor speed without sacrificing pulling force.

Sliding coupling members and torque profiles create a fast hands-free top drive connection that transfers bi-directional torque and axial load.

Modular pilot and power valves actuate large downhole tools with lower power demand and less operational complexity than jarring or motor-based methods.

Pressure-differential valve switching helps subsea landing strings keep large bore access, sealing, and emergency disconnect under extreme loads.

A sinusoidal labyrinth seal with O-rings prevents corrugation deformation and leakage in high-pressure, high-temperature hose couplings.

A segmented inner sleeve and integrated lockout cut corrosion-resistant material use and avoid extra downhole runs in well safety valves.

An offset seat passage lets the flapper swing farther for downhole tool passage without milled pockets, preserving pressure rating and lowering cost.

Recessed wellhead wickers vent trapped fluid between ridges, preventing hydraulic lock and enabling deeper metal seal ring engagement.

Thicker exposed superhard bearing elements and a support ring improve convective heat transfer, limiting overheating and extending bearing life.

A balance chamber with relief and check valves preserves piston pressure differential so the safety valve closes even at low annulus pressure.

A parallel-locking subsea connector cuts component count and cost while using hydraulic preload and secondary unlocking to resist accidental release.

An integrated hollow-rod actuator and ring compensator counters subsea water pressure while cutting size, friction, and oil flow.

Sensor feedback on water content and temperature triggers flowline heating only when hydrate risk rises, helping avoid production stoppages.

A rotating ring coupler engages a complementary profile to transmit bi-directional torque while reducing cross-threading, alignment issues, and thread damage.

A polygonal gooseneck wall adds localized thickness at stress points, helping power swivels withstand higher drilling fluid pressure.
