Pigs/Moles TRIZ Cases

Spring-biased balls on a wedge cone grip pipe inner walls instantly, delivering high holding force without surface damage and easing release.

Visual wear indicators on pipeline pig contact surfaces reveal material loss quickly, helping prevent ineffective cleaning runs and late replacement.

A retainer-guided probe delivers and releases an expanding pipe repair insert inside the pipeline to seal wall breaks without excavation.

A passive alignment mechanism deploys probes perpendicular to pipe walls without centering, handling varying diameters and weld obstacles.

A transparent insulating liquid cools and electrically isolates curing LEDs, improving temperature control and diode life in pipeline lining.

A resettable foam pig uses deformation sensing to detect dents and bends while passing obstructions, reducing inspection tool lodging risk.

A tree diffuser and zoned heating layout spread hot gas evenly in a compact duct lining pig, preventing cold spots and weak liners.

A UAV tracks a geopig's magnetic field through pipeline walls to avoid inertial drift and Faraday cage errors in pipeline location.

A compressed spring stent with a sealing sleeve expands inside a damaged pipe to stop leaks without excavation or interrupting fluid flow.

Inflatable actuators and pressure control let this pipe inspection robot move through debris, adapt to pipe geometry, and collect more accurate data.

An isolation sheet, dual seals, and an ejector create a low-pressure annular workspace for internal pipe wall repair without stopping flow.

Frangible links hold the bladder and liner in place during transport and inflation, improving lateral pipe junction alignment and repair precision.

A gel pig and sealant pig train moves with pipeline flow to seal leaks quickly, pass obstructions, and avoid abrasion and debris.

Partial saturation eddy current modules with variable permanent magnets inspect CRA-lined and heavy wall pipes without couplants or umbilicals.

Independent linear actuators let conduit robot frames translate and rotate through winding pipes for mapping and damage detection.

Radial LED light heads dissipate heat via internal air channels to prevent overheating and enable curing in bent pipes.

Deformable discs and electromagnetic sensors enable a pipe pig to navigate bends and varying diameters without specialist launch stations.

Segmented cartridge design reduces sealing complexity and pressure drops by extracting guide elements from permanent Y-piece structures.

A cylindrical LED curing device delivers electromagnetic radiation to pipeline resin linings.
