Rail Switches TRIZ Cases

An overtie support structure positions indicator bars above ballast to prevent fouling and misalignment during thermal expansion.

Segmented railway sleepers hinge along a rotational axis to fold large switch assemblies, eliminating the need for expensive special wagons during transport.

A multi-part base plate with adjustable sections adapts to varying rail support plates while ensuring reliable transverse force transmission.

Automated milling removes worn material from railway switch frogs while welding robots deposit filler metal, extending component life beyond new parts.

Recessed chambers accept segmented pads that compensate for ballast unevenness, improving positional stability without increasing manufacturing costs.

A vehicle-mounted guidance system steers vehicles along diverging pathways using augmented permanent magnets.

Segmented locking device with breakable pin isolates damage, enabling rapid component replacement and reducing maintenance costs.

Segmented lug with mechanical interlock eliminates thermal alteration and reduces production time.

Segmenting the rail switch beam into independent movable components reduces operational weight and maintenance frequency.

Mobile rail gates enable track switching without obstructing the propulsion mast, resolving interference in pneumatic transport systems.

An AMR sensor measures external magnetic fields to determine vehicle heading, resolving GPS precision limits in closely spaced tracks.
