Pivotable Railway Wagon for Semi-Trailer Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing railway wagons require extensive and costly infrastructure for loading and unloading semi-trailers, as well as being heavy and complex, limiting their use to specialized terminals and increasing environmental impact.
Innovation Solution
A railway wagon design featuring a pivotable beam connected to the wagon end, allowing horizontal and vertical movement of the main wagon portion, enabled by internal power sources like pneumatic, hydraulic, or electric systems, which can be used to load and unload semi-trailers at any location without specialized infrastructure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If extensive infrastructure equipment such as cranes and heavy lift trucks is used for loading and unloading semi-trailers, then the loading and unloading capability is improved, but the infrastructure investment and device complexity increase significantly
Solution Approach 1:
The railway wagon equips itself with a pivotable main portion and support legs, enabling it to perform loading and unloading operations independently without requiring external cranes or heavy lift trucks. The wagon's own structural components are used to facilitate the transfer of semi-trailers.
Solution Approach 2:
The main portion of the railway wagon is designed to be pivotable between a horizontal transport position and a vertical loading position. This dynamic reconfiguration allows the same structure to serve both railway transport and ground loading/unloading functions, eliminating the need for separate specialized infrastructure.
2Ease of operation
If specialized terminals with extensive infrastructure are built for loading and unloading semi-trailers, then the loading and unloading operation is improved, but the infrastructure investment and environmental impact increase
Solution Approach 1:
The railway wagon performs loading and unloading operations using its own pivotable main portion and support legs, eliminating the need for specialized terminal infrastructure. This self-service capability allows operations to be conducted at any location without building dedicated facilities.
Solution Approach 2:
The railway wagon is designed to perform multiple functions: railway transport in horizontal position and ground-based loading/unloading in vertical position. This multi-functionality replaces the need for separate specialized terminals, reducing infrastructure investment and environmental impact.
3Adaptability or versatility
If a pivotable platform is added to the railway wagon for loading semi-trailers, then the loading and unloading flexibility is improved, but the wagon becomes heavier and more complicated
Solution Approach 1:
The main portion of the railway wagon is designed to serve dual purposes: as the cargo-carrying body during railway transport and as the loading platform when pivoted vertically. This multi-functionality adds loading flexibility without requiring a separate dedicated platform structure.
Solution Approach 2:
The loading/unloading function is merged with the main wagon structure by making the main portion itself pivotable. The support legs are integrated into the wagon's end structure, combining the functions of support, positioning, and loading platform into a single integrated system.
4Adaptability or versatility
If the main wagon portion is made pivotable for loading and unloading operations, then the adaptability to different locations is improved, but the structural complexity and weight increase
Solution Approach 1:
The main portion is designed to be the cargo-carrying structure during transport and the loading platform during operations. This universal design enables location flexibility without adding a separate platform, as the same structure serves both purposes.
Solution Approach 2:
The pivotable main portion allows the wagon to dynamically reconfigure between horizontal (transport) and vertical (loading) positions. This dynamic capability provides adaptability to different locations and operations while using the existing wagon structure rather than adding separate components.

AI summary
A railway wagon for transport of for example a semi-trailer (5) comprises - carried by two bogies (1, 2) or the like - a main portion (3), pivotally connected to a rearward bogie (2), and a wagon end (4), connected to a forward bogie (1), the main portion and the wagon end being releasably connected to each other. A beam (10, 15, 18) is to be connected to or is connected to the wagon end (4) for horizontally guiding the main portion (3) at its pivoting out from the wagon end. Means (3 A; 22) are provided for vertically displacing the main portion (3) or a part (23) thereof in relation to the wagon end (4).
