Locomotives TRIZ Cases

A foldable cab seat slides into a side cabinet to add seating without blocking the escape route or consuming driver cab space.

An adjuster pinion meshes with track teeth to let a removable support member reposition easily while avoiding damage during disengagement.

A flexible member shifts a pinion between engaged and disengaged states, making track supports easier to attach, remove, and reposition.

An adjustable wheel and receptacle connection lets the support member shift longitudinally while staying stable in transverse and vertical directions.

A toothed anchor and cam-assisted member improve support positioning on track assemblies while simplifying engagement and release.

A removable support member uses an adjuster pinion to engage or disengage track teeth for easier positioning, secure attachment, and damage prevention.

Curved and angled anchor teeth improve track-to-support engagement, enable Z-direction adjustment, reduce play, and resist dynamic loads.

A horizontal obstacle-mixing-outlet layout shortens sand flow distance, increases storage capacity, and helps prevent leakage and clogging.

A screw conveyor meters grit into compressed air for uniform rail sanding, improving traction on wet rails while cutting air use and clumping.

Offboard weather, track, and schedule data trigger pre-emptive sanding to reduce wheel slip and avoid wasted sand.

Symmetrically distributed expansion tanks around the blower housing increase coolant volume while avoiding asymmetric loads that weaken stability.

Vehicle-aligned and cross fins cool railway power units by using train motion for forced convection and idle periods for natural convection.

A movable screen and control console use linked pivot-slide motion to switch rail cabs between manned and unmanned states without cover plates.
