Railway Couplings TRIZ Cases
- Pneumatic Coupler Control for Safe Electrical Coupler Retraction
Air from the main reservoir pipe triggers valve-controlled electrical coupler retraction during manual or normal uncoupling, reducing damage risk.
- Articulated Vehicle Cable Routing With Rotating Intermediate Holders
Discrete cable clamps and rotating intermediate holders replace guide rails to reduce installation damage and keep articulated-vehicle cables stable.
- Rotating Tensile Restraint Coupling for Towing Load Integrity
A rotatable linkage keeps a tensile restraint closely fitted under towing motion, improving secondary connection reliability under high loads.
- Articulated Vehicle Joint Assembly for Roll-Decoupled Car Bodies
A wishbone-linked joint assembly uses tuned base-bearing stiffness to decouple transverse roll while keeping high longitudinal stiffness.
- Pneumatic Coupler Control for Electrical Coupler Retraction
Pressurized air from the main reservoir retracts the electrical coupler during mechanical uncoupling, preventing damage even without a pneumatic command.
- Vehicle Coupler Load Path Layout to Protect Pin Flanges
A smaller tail-to-body gap shifts impact load away from weak pin flanges, extending coupler life through staged load sharing.
- Traction Coupling Centralized Lubrication for Wear Reduction
Centralized lubricant delivery keeps traction coupling joints protected, cutting wear, manual servicing, and rail vehicle downtime.
