Silo Positioner Traction Roller Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container positioning devices for commercial vehicles, such as silo erecting devices, require large and heavy hydraulic cylinders to move and position containers, leading to a reduced payload due to the bulky and heavy structure.
Innovation Solution
A container erecting device with a traction roller system that allows for efficient transportation and positioning of containers using a compact and lightweight design, eliminating the need for large hydraulic cylinders, and incorporating a hook device and safety latch for secure handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If large and heavy hydraulic cylinders are used to move and position containers, then the container positioning function is achieved, but the payload capacity of the commercial vehicle is reduced
Solution Approach 1:
The patent replaces the conventional hydraulic cylinder system with a mechanical winch system. The winch uses a drum and cable arrangement to pull the container onto the vehicle, substituting hydraulic power with mechanical advantage through cable tension and drum rotation. This eliminates the need for heavy hydraulic components while achieving the same container positioning function.
Solution Approach 2:
The patent extracts and removes the hydraulic cylinder system from the vehicle configuration. By eliminating the hydraulic power source, hoses, and control mechanisms, the design reduces vehicle weight and complexity while maintaining container handling capability through the winch system.
2Adaptability or versatility
If a centrally arranged hydraulic cylinder is used to move the container in the longitudinal direction, then the container can be transported onto the trailer, but the hydraulic cylinder requires considerable overall length leading to bulky and heavy structure
Solution Approach 1:
The patent replaces the long central hydraulic cylinder with a winch-mounted cable system. The cable runs from the winch drum along the vehicle length to the container, providing the necessary longitudinal pulling force without requiring a physically long actuator. This mechanical cable system occupies minimal space compared to a hydraulic cylinder of equivalent stroke length.
Solution Approach 2:
Instead of using a linear hydraulic cylinder extending along the vehicle's longitudinal axis, the patent uses a cable that can be routed through three-dimensional space from the winch position to the container. This allows the force transmission path to bypass spatial constraints, eliminating the need for a long central actuator.

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 traction roller system increases payload capacity by reducing weight and complexity, allowing for greater material loading in containers and vehicles, while the hook device and safety latch ensure secure and damage-free handling.
Implementation Method 1
By means of the traction roller, the container picked up by the tipping frame can be transported from the towing vehicle onto the trailer
