Locomotives TRIZ Cases
- Inclined Fin Heat Dissipation for Railway Vehicle Electronics
Inclined fins optimize natural convection airflow to dissipate heat from railway vehicle electronics when the vehicle is stationary.
- Vehicle Control System for Derailment Prevention on Curved Tracks
A vehicle control system adjusts tractive effort and friction modification to manage wheel-rail forces.
- Interchangeable Rail Cab Control Units via Networked Redundancy
Standardized display and control units connect via Ethernet to calculation units for flexible rail vehicle operation.
- Locomotive Emergency Override System Traction Disconnection
Controller disconnects tractive power before brake application to eliminate excessive wear and ensure safe stopping.
- Railway Vehicle Control Device Using Programmable Supervision Unit
Replacing mechanical relays with a programmable supervision unit reduces the bulk of the driving manipulator while improving adaptability.
- Rail Vehicle Driver Control Assembly Longitudinal Adjustment
A rail vehicle driver control assembly moves a lever and armrest together along the longitudinal axis to match operator dimensions.
- Rotating Railway Cab with Locking Mechanism
A pivoting driver console rotates to face forward or backward, using an indexing pin to lock the seat and maintain visibility without redundant equipment.
- Rail Grit Analysis via Wheel Motion Signals
A rail grit analysis system evaluates wheel motion signals to determine grit density and integration at the contact point.
- Counter-Pressure Flow Device for Rail Sanding Pipes
A controllable counter-pressure device generates back pressure against sand flow to regulate mass delivery in pneumatic rail sanding systems.
- Rail Vehicle Footrest Height Adjustment Mechanism
Articulated three-point bearing system with parallel support levers enables smooth height adjustment for rail vehicle foot platforms.
