Transport Cart Strapping Layout for Partial and Variable Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo transportation systems face challenges in efficiently securing cargo, particularly when the loading surface is only partially loaded or when dealing with different cargo types and loading heights, as traditional strapping methods are time-consuming and require multiple operators.
Innovation Solution
A cargo wagon system featuring a loading platform with at least one tensioning means and a strapping system, where the tensioning means can be moved and positioned relative to the loading platform to adapt to different cargo configurations, and can be guided and tensioned using a common conveying device, allowing for secure cargo retention with minimal operator effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional individual straps are used to secure cargo, then cargo can be secured, but the process is time-consuming and requires multiple operators
Solution Approach 1:
The patent combines multiple individual strap operations into a single integrated strapping system. The conveying device transports multiple straps simultaneously, and the tensioning device applies tension to all straps in one coordinated action, replacing the traditional method of separately wrapping and tightening each strap individually. This merging of operations enables one operator to secure cargo quickly without the time loss associated with manual individual strap application.
2Productivity
If movable side walls are used to secure cargo, then cargo can be secured quickly, but the system only functions when lower bale layers are not considerably wider than upper bale layers
Solution Approach 1:
The strapping system is designed to be universally applicable to various cargo types and loading configurations. Unlike movable side walls that require specific cargo dimensions, the straps can accommodate any cargo shape, size, or stacking arrangement. The system can secure both uniformly loaded and partially loaded wagons, as well as cargo with varying bale layer widths, making it a multi-functional solution that adapts to different securing needs without structural modifications.
3Productivity
If a rail arrangement is used for strapping, then cargo can be secured, but the rail arrangement is separate and distinct from the transport wagon and cannot be utilized in every situation
Solution Approach 1:
The strapping system is merged with the transport wagon structure itself, eliminating the need for separate external rail arrangements. The conveying device and tensioning device are integrated components of the wagon, with the conveying device positioned to access cargo on the loading platform and the tensioning device mounted on the wagon frame. This integration reduces device complexity and allows the system to be used in all situations where the wagon is deployed, including agricultural use in fields, without requiring separate infrastructure.
4Reliability
If a driven strapping system is used, then uniform loading can be secured reliably, but the system does not accommodate partially loaded wagons or very different loading heights
Solution Approach 1:
The strapping system incorporates dynamic elements that allow it to adapt to different loading configurations while maintaining reliable securing. The conveying device can be positioned at different locations along the loading platform, and the tensioning device can apply variable tension forces. The straps themselves are flexible and can be routed around cargo of different heights and shapes. This dynamic adaptability enables the system to reliably secure both uniformly loaded and partially loaded wagons, as well as cargo with varying loading heights, without sacrificing securing reliability.

AI summary
A transport wagon with a loading platform configured to have a loaded state, wherein in the loaded state, cargo may be loaded onto the loading platform and wherein the loading platform extends along a longitudinal axis; a strapping system configured to secure the cargo on the loading platform, wherein the strapping system comprises at least one tensioning means configured to be guided, with the aid of a conveying device, at least partially around the cargo loaded onto the loading platform thereby tensioning the cargo against the loading platform; wherein the loading platform is delimited at a frontal end by transverse side parts comprising the conveying device of the strapping system; and wherein the at least one tensioning means is affixed to the transport wagon and configured to move along the longitudinal axis relative to the loading platform.
