Power Rails TRIZ Cases
- Heated Power Rail Bracket Assembly for Moisture Leakage Control
A resistor between conductive rail clips generates heat to evaporate moisture, reduce leakage, and keep elevated power rails stable.
- Split Fishplate Rail Joint for Curved Power Rail Alignment
A split fishplate joins narrowed power rail ends to maintain stable electrical contact across modular curves, slopes, and terrain shifts.
- Modular Power Rail Base With Nested Couplers for Uneven Haul Routes
Nested tubular couplers keep modular elevated power rail barriers aligned on curved, sloped haul routes to prevent machine disconnection.
- Telescopic Rail Grounding Interconnection for Variable Rail Spacing
A telescopic, rotatable rail grounding link adapts to varying rail spacing and orientation for secure electrical interconnection.
- Conductor Ramp Assembly for Self-Aligning Rail Power Connection
Non-conducting ingress rails guide a mobile machine contactor onto conductive rails, easing alignment and cutting connection downtime.
- Elevated Power Rail Base With Nested Couplers for Uneven Haul Routes
Nested barrier couplers let elevated power rails adapt to slopes and steering deviations while maintaining stable electrical connection.
- Pre-Contact Clamp Geometry for Earlier Sliding Contact Engagement
An extended contact tongue and insertion aid let data sliding contacts engage earlier and stay connected longer than power contacts.
- Battery Tender Traction Assembly for Catenary-Free Locomotive Operation
An external battery tender feeds the locomotive roof line, enabling catenary-free operation without costly onboard power-circuit modification.
- Insulated Busbar End Ramp for Current Collector Guidance
A removable insulating guide ramp improves current collector entry while reducing wear, assembly complexity, and electrical hazard exposure.
- Busbar Spacer and Cover Latching for Tool-Free Assembly
Integrated latching and fixing devices secure busbars and covers without tools, cutting assembly effort while keeping repairs fast and reliable.
- Trolleybus Current Collector Ridge for High-Current Battery Charging
A flat member with an axial ridge shifts charging current to metal shoe edges, reducing carbon wear and contact overheating during trolleybus battery charging.
- Pantograph Cam Locking for Secure Contact Strip Storage
A cam and anti-rotation shaft lock the pantograph contact strip in storage, preventing unintended deployment and wear under load.
- Current Collector Cam Locking for Secure Storage Position
A cam and anti-rotation lock secures the current collector contact strip in storage, blocking unintended return under operational loads.
- Third Rail Insulating Cover Assembly for Arc and Water Resistance
A polycarbonate/ABS cover and bracket assembly improves third rail insulation, arc resistance, dielectric strength, and water runoff.
- Insulating Busbar Mounting Structure for Low-Leakage Assembly
An insulating mounting structure enables lateral busbar insertion, cuts assembly complexity, and prevents leakage currents in flexible layouts.
- Composite Rail Profile With Insert Rods For Welded Bonding
Insert rods engage lateral slots in the carrier profile and weld to the strip, preventing long-term detachment under high loads.
- Insulating Support for Tramway Power Supply Tracks
Central groove and symmetrical ducts reduce parasitic signal interference in tramway power supply tracks.
