Pump Components TRIZ Cases

Variable density foam geometry absorbs blade-off energy while maintaining containment strength.

Distributed spacers isolate dissimilar metal sheaths from substrates to prevent galvanic corrosion.

Spaced rotating discs in a bladeless impeller fan entrain air via viscous forces, resolving efficiency losses from dominant viscous drag in thin devices.

Segmented housing parts separate motor cooling from gas flow paths, reducing deflections and improving fan efficiency.

A conical metal load spreader secures composite fan platforms to metal disks using a countersink and filler ring.

Insertion components form secondary flow ducts within support recesses to manage blade tip boundary layers.

Curved step portions on blade positive pressure surfaces generate vortex flow to enhance axial fan aerodynamic performance.

Segmented inserts guide fiber winding on a removable core, resolving tooling complexity while optimizing reinforcement direction for mechanical resistance.

A cooling fan uses a moving baffle module to redirect reverse airflow for dust expulsion.

Segmented movable sealing walls maintain integrity during LP shaft removal, preventing oil leakage and contamination risks.

Segmenting the metal sheath at minimized bending moments prevents detachment during foreign object impact while reducing overall blade weight.

A stator part separates the floating ring from the rotor, reducing bulky seals to shrink internal diameter while maintaining effective oil and air barriers.

A centrifugal air compressor uses a carbon-filled polyetheretherketone annular portion to limit heat transfer from the compression wheel.

A centrifugal hydrogen compressor uses a flywheel-driven gearbox to deliver high flow rates without reciprocating parts.

A flat flow-conducting grille with radial webs guides air through a planar structure to reduce axial height.

A machined vane arm with radially stepped surfaces and a D-shaped opening provides precise attachment to the vane stem.
