Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current freight transport systems, particularly road and rail, face inefficiencies in terms of speed and energy usage due to limited transport capacity, high costs, and the need for frequent reloading and interruptions in traffic, which hinder the effective utilization of existing rail infrastructure.
Innovation Solution
A bi-modal transport system featuring integrated route networks and bi-modal vehicles designed to operate on both rails and roads, with specialized junctions and changeover areas that allow seamless transitions between rail and road modes without disrupting ongoing traffic, utilizing a combination of rail and road wheels with a drive train capable of adapting to different energy sources and guidance systems for safe navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If road freight transport is used for door-to-door transport, then transport speed and flexibility are improved, but fuel consumption and emissions increase
Solution Approach 1:
The patent combines road and rail transport systems into an integrated bi-modal network where vehicles can switch between road and rail infrastructure. This merging allows the system to leverage the speed and flexibility of roads while utilizing the energy efficiency of rails for longer distances, thereby reducing overall fuel consumption while maintaining transport speed.
Solution Approach 2:
The bi-modal vehicles are designed with universal capability to operate on both road and rail networks. This multi-functionality enables the same vehicle to utilize different transport modes depending on the route requirements, optimizing the balance between speed (road) and energy efficiency (rail) for each segment of the journey.
2Use of energy by moving object
If rail freight transport is used for long-distance transport, then energy consumption is reduced, but transport capacity per unit time is limited by train formation regulations
Solution Approach 1:
The patent introduces dynamic switching capability where vehicles can transition between road and rail modes based on real-time requirements. This dynamic approach allows the system to optimize for energy consumption on rail segments while maintaining high productivity through road segments, breaking the static limitation of train formation regulations.
Solution Approach 2:
The journey is segmented into multiple phases with different transport modes. Rather than requiring entire trains to wait for formation, the system segments the transport task so that individual vehicles or groups can switch modes independently, increasing overall transport capacity per unit time while maintaining energy efficiency on rail segments.
3Adaptability or versatility
If bi-modal vehicles switch between rail and road networks, then utilization of rail infrastructure is improved, but traffic flow may be obstructed at connection points
Solution Approach 1:
The patent introduces specialized transition zones as intermediary areas between road and rail networks. These zones serve as buffer areas where vehicles can switch modes without directly interfering with main traffic flows on either network, thereby maintaining ease of operation while improving rail infrastructure utilization.
Solution Approach 2:
Vehicles perform mode switching in advance at designated transition zones before entering main traffic corridors. This preliminary action prevents obstruction of ongoing traffic by completing transitions in dedicated areas, maintaining smooth traffic flow while enabling versatile use of both road and rail infrastructure.
4Adaptability or versatility
If reloading is required to switch between road and rail transport, then flexibility of transport mode is improved, but time consumption and costs increase
Solution Approach 1:
The patent merges the road and rail vehicles into a single bi-modal unit that can operate on both networks without requiring separate loading and unloading operations. This combining eliminates the time-consuming reloading process while maintaining the flexibility to switch between transport modes, directly addressing the time loss associated with traditional intermodal transport.
