Machines/Engines TRIZ Cases

A floating turbine apparatus driven by wave motion and tidal currents generates electricity via an integrated air pump system.

Merging guiding ribs and reinforcement elements reduces steam collisions and pressure losses in low-pressure turbine exhaust casings.

An elevator door leaf integrates an ejection device to remove the operating panel.

Integrating a strain gauge into the common rail transverse wall eliminates external mounting complexity while maintaining precise pressure measurement.

Distance-dependent smoothing suppresses parasitic echoes in ultrasound signals while preserving local maxima resolution.

A patterned elastomeric polymer sleeve replaces fabric to prevent aneurysm risks from excessive expansion and wear in implantable prostheses.

A hybrid monitoring system uses downward laser beams and acoustic sensors to detect blade deformation and tower vibration on offshore wind turbines.

Segmented sailcloth blades capture wind energy through controlled gaps to drive rotational motion in a compact power generation device.

Segmented oil channels supply lubrication to the input gear and eccentric cam, resolving reliability issues in variable compression-ratio mechanisms.

Contoured air tubes route vertically through the engine compartment while angle adapters transition airflow to the intake, resolving space constraints.

A shaft break detection system uses recursive least squares to determine a discrete time constant from rotational speed measurements.
