Railway Lighting TRIZ Cases

A compartmented curved profile with a flexible LED strip and closing band creates seamless gangway lighting with lower cost and cleaner appearance.

ETA-based interior brightness adjustment helps vehicle occupants adapt to outside light faster while limiting receptor overload.

ETA-based interior brightness adjustment helps vehicle occupants adapt to outside light faster while limiting unnecessary energy use.

A modular light profile on the door closing edge guides and scatters LED light for clear passenger visibility with less soiling risk.

A dual-source cabin lamp keeps low-level light on from a storage battery during power loss, improving railcar evacuation safety without extra wiring.

Visible light from interior LEDs cuts wiring and radio leakage while reliably controlling seats and displays inside vehicles.

A one-piece snap-fit mounting plate secures vehicle wall light sources quickly without tools, even when the mounting area is not visible.

Motorized latch control with weight sensing and cabin lighting enables touch-free stowage bin access while blocking opening during restricted flight periods.

Flexible wired modules and a shared translucent diffuser simplify long vehicle lighting assemblies while protecting electronics and maintaining uniform illumination.

A compound curvature display surface projects pre-distorted media to create undistorted views from multiple vantage points.

A rail vehicle signaling device generates light distribution patterns through exterior glazing for clear door status visibility.

A tramcar power system combines a fuel cell, super capacitor, and power battery to deliver high acceleration and extended mileage.

Segmented control modules reduce wiring complexity and installation space for rail vehicle lighting.
