Interchangeable Train Units for Flexible Passenger-Freight Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing impact of road freight traffic on urban areas causes economic and environmental damage, while rail traffic lacks sufficient capacity for passenger transport during peak hours, leading to inefficiencies and overcrowding, with domestic rail freight traffic being negligible compared to road freight.
Innovation Solution
Adapting trains and infrastructure to allow flexible transport of passengers and freight by using interchangeable passenger and freight units, equipped with automatic loading and unloading systems, indoor navigation, and a coordination system to optimize capacity utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If rail infrastructure is adapted for flexible passenger and freight transport, then transport capacity and efficiency are improved, but infrastructure complexity and conversion costs increase
Solution Approach 1:
The patent implements multi-functionality by designing train units that can operate in both passenger and freight modes. The infrastructure is adapted to accommodate interchangeable units, allowing the same rail network to serve dual purposes. This resolves the contradiction by increasing transport capacity without proportionally increasing infrastructure complexity, as the existing infrastructure is utilized for multiple functions.
Solution Approach 2:
The system employs dynamic configuration where train compositions can be adjusted based on demand. Units can be coupled or decoupled, and configurations changed to match passenger or freight requirements. This dynamic adaptability allows the system to optimize capacity utilization without requiring separate dedicated infrastructure for each transport type.
2Productivity
If trains are converted for freight transport during peak hours, then freight capacity increases, but passenger transport quality and comfort may deteriorate
Solution Approach 1:
The train fleet is divided into separate passenger units and freight units that can be independently configured. This segmentation allows passenger and freight services to be optimized independently, ensuring that passenger transport quality is maintained when passenger units are deployed, while freight capacity is maximized when freight units are used. The coordination system manages these segments to prevent quality deterioration.
Solution Approach 2:
The system dynamically adjusts train compositions based on real-time demand. When passenger demand is high, passenger units are prioritized to maintain service quality. When freight demand is high, freight units are deployed. This dynamic resource allocation ensures that transport quality is maintained during peak passenger hours while still providing adequate freight capacity through flexible unit interchangeability.
3Productivity
If more train units are deployed to increase capacity, then transport demand is met, but operational costs and resource consumption increase
Solution Approach 1:
By designing units that can serve multiple purposes (passenger or freight), the system maximizes the utilization of each unit. This reduces the total number of units needed compared to having separate dedicated fleets, thereby reducing material consumption and operational costs while still meeting transport demand.
Solution Approach 2:
The system changes operational parameters such as unit configuration, coupling arrangements, and route assignments to optimize capacity utilization. By adjusting these parameters dynamically, the system achieves higher productivity from the same resource base, reducing the need for additional material投入.

AI summary
A method and system for the flexible combined transport of persons and/or freight via rail or road. A coordination system coordinates the total transport capacity and the specific demand for transport of passengers and freight in real time and dynamically. The coordination system registers the existing capacity of persons and freight of a transport means, determines a residual capacity, defined by the difference between the passenger capacity and the passenger transport demand, and determines a transformation capacity, which is determined by the size of the residual capacity that can be transformed for the carriage of freight. The freight capacity is determined by the transformation capacity and the existing freight capacity. A multi-functional transport modality for rail or road and other support means for the realization of an efficient and resilient mobility system for passengers and freight.
