Rail Devices TRIZ Cases

A magnetic flux reduction structure limits induced current in adjacent coils, cutting power loss and impedance interference in contactless power transfer.

A single exothermic weld joins multiple rail conductors at one point, cutting connection footprint, thermal damage, and accidental removal.

Dynamic switching between wireless power, onboard storage, and regenerative energy keeps article transport vehicles running and reduces storage wear.

Vehicle ID and activation keys energize only the needed road segment, improving electrical safety and enabling separate billing.

Image sensors on worksite machines detect charging rail misalignment early, helping prevent power disconnections and downtime.

Opposed current paths create electrodynamic repulsion that helps keep switching contacts closed under high current, raising load capacity.

Using an E-shaped core for electromagnetic induction, this case powers retrofit cart temperature sensing without shutdown or added wiring.

Asymmetric single-phase and multi-phase coil layouts cut power pulsation, shrink charging hardware, and help protect vehicle batteries.

Insulated rail joints isolate a corrosion-prone rail section while coupling adjacent rails to block stray current and extend track life.

Phase-adjusted synchronization compensates for signal transmission delays between power supply units, improving AC phase accuracy on contactless feeding lines.

A recessed conductor rail with a sub-12 mm slot enables high-power static and dynamic EV charging while limiting finger access and switchgear complexity.

Vehicle ID and activation keys enable only the needed road segment, improving electrical safety and separating power use for accurate billing.

Separate radial electrical rings and axial pneumatic bores keep mining work machines powered and actuated during long travel with fewer interruptions.
