Double Pocket Freight Wagon Trough Positioning for Mixed Cargo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail-bound freight wagons with integrated cargo troughs are inflexible and economically inefficient, often requiring additional storage space when not in use, and complex systems like Cargobeamer wagons are technically complex and expensive.
Innovation Solution
A freight wagon design that allows simultaneous transport of container-shaped cargo without resting on the trough's loading surface, equipped with fastening elements and a ramp assembly for flexible positioning and securing of various cargo types, including containers and semi-trailers, without needing to remove the trough.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the trough is made removable and movable between different positions, then the adaptability and ease of operation are improved, but the device complexity increases due to additional fastening elements and positioning mechanisms
Solution Approach 1:
The fastening system is segmented into multiple independent fastening elements (110a, 110b) that can be individually engaged or disengaged. This allows the trough to be positioned at different locations along the longitudinal beams without requiring a complex unified fastening mechanism, thus achieving positioning flexibility while keeping each individual fastening point simple.
Solution Approach 2:
The trough is designed to be movable between different positions (loading position and unloading position) rather than fixed. The fastening elements enable dynamic repositioning of the trough along the longitudinal beams, allowing the same structure to serve multiple functions at different locations without requiring separate structures for each position.
2Manufacturing precision
If the trough is inserted into the pocket defined by longitudinal beams, then the manufacturing precision and structural stability are improved, but the ease of operation decreases due to the need for precise alignment and fastening
Solution Approach 1:
The longitudinal beams are pre-formed with pockets that precisely receive the trough, and the fastening elements are pre-positioned on the beams. This preliminary preparation ensures that when the trough is inserted, it automatically achieves the correct positioning and alignment without requiring complex adjustment procedures, thus maintaining precision while simplifying the operation.
Solution Approach 2:
The fastening elements (110a, 110b) act as intermediaries between the trough and the longitudinal beams. These intermediaries simplify the connection process by providing standardized engagement points that align the trough with the pocket, making both the precision alignment and the operational ease achievable simultaneously.
3Productivity
If the freight wagon is designed as a double pocket wagon with specific structural components, then the productivity and cargo capacity are improved, but the device complexity increases due to the multiple beams and pieces
Solution Approach 1:
The longitudinal beams (11.1, 11.2) serve multiple functions: they provide structural support, define the pockets for trough insertion, and carry the fastening elements for trough positioning. This multi-functionality allows the wagon to handle various cargo types and configurations without requiring separate specialized structures for each function, thus improving productivity while managing structural complexity.
Solution Approach 2:
The trough is inserted into the pocket defined by the longitudinal beams, creating a nested structure. The fastening elements are then attached to the beams to secure the trough within the pocket. This nesting approach allows the wagon to accommodate different sized troughs and cargo configurations within the same structural framework, enhancing cargo capacity and productivity without proportionally increasing overall structural complexity.

AI summary
The present invention relates in particular to a freight wagon (1), e.g. in the form of a double pocket wagon (1), with a head piece (12) at a front end of the freight wagon (1), an end piece (13) at a rear end of the freight wagon (1), and two longitudinal beams (11.1, 11.2) extending between the head piece (12) and the end piece (13), wherein a trough (2) for cargo is provided, defining a trough loading area (20), and the longitudinal beams (11.1, 11.2) define a pocket (10) into which the trough (2) is inserted. According to a first aspect, fastening elements (110a, 110b) for the trough (2) are provided on the longitudinal beams (11.1, 11.2), which define a loading position for the trough (2) in the pocket (10) of the freight wagon (1).
