Railway Components TRIZ Cases

A pivoting step carrier forms part of the vehicle cladding to simplify maintenance access.

Segmented step surfaces resolve the contradiction between avoiding platform collisions and facilitating vehicle access by filling gaps with localized stability.

A floor-mounted flexible barrier system uses movable elements guided by parallel rails to create dynamic passage openings along the platform facade.

A contactless driving module uses permanent magnets to propel a vehicle along guide rails without physical wheel contact.

Nesting a refrigeration unit inside the driver's cab cabinet resolves space constraints while maintaining storage reliability.

A folding stair construction with a Z-shaped surface element and mounting device provides additional stepping surfaces when extended.

An internal drive assembly within a hollow tarp spool reduces system complexity and protects components from environmental exposure.

Variable-speed rotating clamps enable in-place vehicle acceleration and deceleration, eliminating long station sections and reducing friction wear.

Segmented frame structure widens to resolve adaptability versus complexity trade-offs in conveyor systems.

A folding staircase uses a spring-loaded lifting mechanism to bias the stringers and threshold plate toward a stowed position.

Tower-mounted rollers support a cantilevered gate, reducing installation complexity and excavation needs for existing platforms.

Laser welding joins different high-strength steel grades in a vehicle door inner panel, reducing weight while maintaining side intrusion resistance.

Routing the ascent through the central support resolves the trade-off between vehicle safety clearance and manageable equipment handling steepness.

Sensors measure distance between the running board and platform edge, enabling automatic extension as a bridge or ramp to resolve height mismatch issues.

A hinged shelf rotates about a console axis to provide stable support for electronic devices.
