Movable Partition Unloading System for Transport Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles with movable partitions for unloading materials face issues such as reduced load volume, high costs, torsional stress, and premature wear of traction systems, especially when unloading sticky materials or on non-horizontal surfaces.
Innovation Solution
A vehicle with a container featuring flexible mechanical connections, such as cables, connected to a motor assembly that pulls a movable partition rearward, with the connections positioned to reduce stress and prevent tipping, and side walls that can be made of solid steel without hollow sections, minimizing damage and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a movable partition is pulled by traction cables connected to a motor, then the container can be made with solid side walls, but the partition undergoes significant torsional stress and may tip over
Solution Approach 1:
A guide assembly acts as an intermediary between the partition and the container walls, providing a constrained path for partition movement. The guide assembly includes guide surfaces that prevent lateral displacement and tipping of the partition during retraction, while allowing the solid side walls to maintain their structural strength.
2Device complexity
If traction cables are used to pull the partition, then the system is simpler than hydraulic actuators, but the cables are subject to impacts from falling materials and can be damaged or wear prematurely
Solution Approach 1:
The guide assembly serves as a protective intermediary that shields the traction cables from direct exposure to falling materials. The guide surfaces and structural configuration of the guide assembly intercept and redirect materials away from the cables, preventing impact damage and premature wear while maintaining the simplicity of the cable-based traction system.
3Length of moving object
If a telescopic actuator is used to move the partition in long containers, then the partition can be moved throughout the container, but the actuator is heavy and expensive
Solution Approach 1:
The container is segmented into functional zones with the partition serving as a movable divider. The guide assembly is positioned at strategic locations to enable the partition to traverse the entire container length using a compact, non-telescopic actuator. The guide surfaces ensure stable movement throughout the container without requiring a heavy telescopic actuator.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a more durable and low-maintenance unloading system that reduces stress on the partition and minimizes damage to the mechanical connections, allowing for efficient unloading without the need for tipping, even on non-horizontal surfaces.
Implementation Method 1
a first flexible mechanical connection, a front end of which is connected to a left end of the partition and extends first horizontally towards the back of the vehicle along an inner face of the left side wall, then downwards or upwards via at least one first pulley

AI summary
A vehicle on which a container (1) is mounted for transporting materials, said container comprising a movable partition (10) extending transversely inside the container. The vehicle comprises a motor (16) pulling on a pair of cables (14a, 14b), the front ends of which are connected to the partition (10) on either side, in order to pull the partition (10) towards the rear of the container so as to unload the materials. The cables run along the side walls (4a, 4b) of the container, at a distance from a bottom of the container. The side walls (4a, 4b) of the container have projections (24a, 24b) each extending towards the inside of the container and overhanging the cables so that said cables are protected from falling materials during loading of the container from above.
