Engine Fuctions TRIZ Cases

Dual electric motors and clutch assemblies decouple fan speed from the low pressure compressor, improving thrust and engine operating flexibility.

A shared solenoid and braking circuit cuts IGBT count and board area in engine starters while adding BIT-based switch fault detection.

A shared oil room and directed oil channels lubricate both gear stages and machine bearings, cutting size, weight, and lubrication complexity.

An epicyclic gear train and motor-generators decouple low-pressure compressor speed from the low spool to improve gas turbine efficiency.

Switchable dual electrical machines share starting torque and current in a gas turbine, cutting starter-generator weight while preserving fault tolerance.

Three interlocking packing components create a low-torque seal for gas turbine instrument leads, reducing lead damage and leak paths.

Excess turbine energy is diverted into hydraulic storage and reused during low flow to stabilize generator output and avoid braking losses.

A common-shaft hermetic turboexpander-generator cuts footprint, leakage, and operating cost in waste heat power recovery.

A Venturi tower base channel accelerates thermal convection airflow to deliver steadier generator output without relying on unstable natural wind.

Internal oil spray cools generator housing seals in extreme heat, keeping elastomeric seals below temperature limits and preventing failure.

By increasing generator load on the LP shaft during deceleration or surge, the engine slows faster and stays closer to the compressor working line.

A buoyant tank, vertical gears, and automatic locking convert tidal motion into power while maintaining stability in harsh ocean storms.

A differential gear with an interference-constrained second shaft lets blade torque reach the generator even when only one axle is driven.

A manifold that combines coolant ports and electrical connection in a generator assembly cuts interface complexity, weight, and maintenance burden.

A flange-fixed holding sleeve protects permanent magnets from centrifugal force while cutting rotor parts and simplifying compressor motor assembly.

Waste heat from a hydrogen fuel cell and burner heats cryogenic turbine fuel, cutting fuel consumption while supplying electrical power.

An annular rotor-stator layout cuts axial thrust on offshore hydro units, reducing thrust bearing wear, downtime, and maintenance cost.

Falling weights drive linked hydraulic pistons to generate electric power with lower heat loss and no combustion byproducts.

An engine-integrated stator and rotor layout removes heavy energy storage while preserving maintenance access and aerodynamic performance.
