Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for loading and unloading roll-off containers on road vehicles require significant height and movement freedom, limiting their use in confined spaces and increasing the complexity and cost of the loading process.
Innovation Solution
A road vehicle with a device featuring laterally arranged guide rollers and a container moving device that can be tilted and pivoted, equipped with a gripper mechanism and a bendable frame section, allowing for reduced height and movement requirements during loading and unloading, enabling use in previously inaccessible environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a crane is mounted on the transport vehicle for loading and unloading containers, then the loading capacity is improved, but the device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent removes the crane from the transport vehicle entirely, extracting the lifting function and replacing it with a simpler container moving device that utilizes the vehicle's own frame and rollers. This eliminates the complexity and cost of mounting a crane while maintaining loading capability.
Solution Approach 2:
The transport vehicle is designed to load and unload containers using its own integrated device, eliminating the need for external cranes. The vehicle's frame, rollers, and moving device work together as a self-contained system, making the vehicle self-sufficient for container handling operations.
2Productivity
If a crane is provided at the location for container placement, then the loading capacity is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent eliminates the need for external cranes at loading locations by extracting the lifting function from the environment and integrating it into the transport vehicle itself. This removes the need for expensive crane infrastructure at container placement locations.
Solution Approach 2:
The transport vehicle performs its own loading and unloading operations without requiring external crane assistance. The integrated container moving device enables the vehicle to handle containers independently, eliminating the need for expensive external lifting equipment at work locations.
3Productivity
If the container moving device is mounted on the frame, then the loading capacity is improved, but the height and movement requirements increase
Solution Approach 1:
The container moving device is designed to be tiltable and pivotable, allowing it to adapt its position and orientation during loading operations. This dynamic capability enables the device to operate in confined spaces with limited height and movement freedom by adjusting its configuration rather than requiring fixed large clearances.
Solution Approach 2:
The device utilizes tilting and pivoting movements to change the spatial dimensions required for operation. By rotating and tilting the container moving device, the system can perform loading operations in areas with restricted vertical and horizontal clearances, effectively transforming the dimensional requirements through angular movements.
4Stability of the object's composition
If guide rollers are arranged laterally at the rear end, then the stability during loading is improved, but the device complexity increases
Solution Approach 1:
The guide rollers are integrated into the existing frame structure at the rear end of the vehicle, combining the guiding function with the structural elements already present. This merging of functions adds stability without requiring separate, complex guiding mechanisms.
Solution Approach 2:
The laterally arranged guide rollers serve multiple functions: they guide the container during loading, support the container weight, and maintain proper alignment. This multi-functionality provides stability while avoiding the need for additional specialized components that would increase device complexity.
