Pump Components TRIZ Cases

A rotating blade design uses leading edge inflection points and trailing edge grooves to alter fluid flow patterns.

A fan assembly uses a movable insert to dynamically adjust the throat gap based on rotational speed.

A fan assembly uses a threaded endcap to retain the module for quick field replacement without tools.

Movable coupling features on the fuel pump assembly shift positions along support structures to accommodate varying fuel tank depths and shapes.

Helical shaft grooves move gas from the thrust bearing to a collection chamber, preventing wear and failure caused by excess gas accumulation.

Segmenting the connection into hub and boss zones reduces press force requirements while maintaining alignment and preventing yield point exceedance.

Integrated rim fixing elements eliminate complex bolted flanges, reducing assembly cost while maintaining platform retention.

A fan securing device uses adjustable locking units and connecting arms to clamp cooling fans between holders without bolts.

Radially deflectable fingers accommodate thermal expansion of exhaust struts, reducing stress from mismatched growth between inner and outer shrouds.

Variable scroll area enlargement reduces flow resistance while recovering static pressure, resolving the trade-off between productivity and energy loss.

Segmented variable pitch inlet guide vanes adjust airflow angle to prevent surge and stall during high thrust operations.

Capillary channels in porous material return lubricant to the reservoir, eliminating gravity dependency for reliable operation in any orientation.
