Steam Locomotives TRIZ Cases

A self-contained motorized pinion kit moves mobile cabinets with less manual effort, avoids complex wiring, and stops when obstacles are detected.

Segmenting the locomotive power plant into independent gas and steam turbines with a selective clutch resolves complexity and volume constraints.

A controller uses PID logic to adjust maglev landing gear position for precise height management.

A railway bogie design integrates secondary suspensions with the motor casing to reduce transverse bulk and structural mass.

An elastomeric suspension linkage absorbs displacement and torsion between a traction motor and truck frame, reducing unsprung mass and dynamic track forces.

C-channel reinforcing members inside the housing boost secured section strength without increasing mass.

Wind turbines capture kinetic energy from opposing airflow to power high-speed ground transport, reducing reliance on carbon-fueled generation.

Curved end teeth on rack and pinion rods prevent jamming at rod joints by allowing the driving sprocket to roll off smoothly.

Resilient cross-members and a five-link arrangement adjust the linear induction motor air gap, resolving roll-pitch coupling in suspension systems.

A hydrogen fuel cell hybrid locomotive air system determines compressor speed and torque set points to deliver precise air mass flow for requested power levels.

Replacing the operator cab with a fuel tank stores alternative fuels without removing revenue-generating freight cars from the consist.

Segmenting the drive system onto the bogie chassis eliminates mechanical complexity while enabling a wide low corridor for unrestricted seat placement.

A portable transition device interfaces conventional locomotives with wired distributed power trains to translate multi-unit control signals.

A bogie frame lateral beam features a flattened intermediate section for device mounting.

A simulation module evaluates proposed vehicle schedule changes against current network states to optimize traffic flow.

A model train pantograph uses a motor-driven gear train to raise and lower an upper collector unit.
