Active Rail Transport Steering via Scanning Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated rail transport systems lack the ability to change direction at junctions and crossings, operate on different track gauges, and efficiently manage high-speed traffic without intermediate stops, leading to limitations in flexibility and energy efficiency.
Innovation Solution
The synchrotrain system employs three independently liftable and lowerable scanning systems for steering, allows for track gauge changes during operation, and uses linear motors for acceleration and deceleration, with a network of control centers managing traffic flow and energy distribution to minimize stops and optimize route planning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single scanning system is used for steering, then the system structure is simple, but the system cannot change direction at junctions or crossings
Solution Approach 1:
The patent divides the scanning system into multiple independent scanning systems (first scanning system for conventional rails, second scanning system for additional guidance rails). Each scanning system can be independently activated or deactivated, allowing the vehicle to navigate different track configurations including junctions and crossings without requiring a complete redesign of the steering mechanism.
Solution Approach 2:
The patent implements dynamic switching between different scanning systems based on the track configuration. The control system actively selects which scanning system to use (first or second) depending on whether the vehicle is approaching a junction, crossing, or normal section, enabling adaptive direction changing capability while maintaining operational simplicity.
2Adaptability or versatility
If the scanning system is fixed for a single track gauge, then the system is simple, but it cannot operate on different track gauges
Solution Approach 1:
The patent designs the scanning system to perform multiple functions by incorporating both a first scanning system for conventional rails and a second scanning system for additional guidance rails. This multi-functional configuration allows the same vehicle to operate on different track gauges and rail configurations without requiring physical modification, achieving universality across various railway networks.
3Loss of time
If intermediate stops are made for direction changes or gauge changes, then the system operation is simple, but stop and waiting times increase
Solution Approach 1:
The patent enables continuous operation by allowing direction changes and track gauge transitions to occur while the vehicle is in motion. The multiple scanning systems work together to maintain steering control during junctions and crossings, eliminating the need for intermediate stops and maintaining continuous useful action throughout the journey.
4Productivity
If high-speed operation without intermediate stops is implemented, then productivity increases, but the system cannot handle junctions and crossings
Solution Approach 1:
The patent introduces additional guidance rails as an intermediary element that works in conjunction with conventional rails at junctions and crossings. The second scanning system reads these additional guidance rails to provide steering information, enabling high-speed vehicles to navigate complex track configurations without reducing speed or requiring intermediate stops, thus maintaining productivity while handling junctions and crossings.

AI summary
An active rail transport system for the automated transport of persons or goods on conventional rails includes a car having an autonomous drive unit, brake and steering mechanism. The car may be directed away from a running through car, decelerated unloaded and/or loaded and thereafter redirected to the running through car after the speed of the car is adjusted to the speed of the running through car. A first conducting system which includes a first scanning system provides continuous traction. The first scanning system can be adjusted to account for different rail gauges during travel. A second conducting system includes scanning systems and associated guide rails for determining the direction of the car when going over diverge points and crossings.
