Oscillating Hazardous Waste Roll-Off Container for Spill Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll-off containers for hazardous waste management face challenges in maintaining a horizontal orientation during loading and transport, leading to uncontrolled spillage risks and high implementation costs due to the need for specialized containment systems.
Innovation Solution
A roll-off container with an oscillating structure for hazardous waste collection units that maintains a horizontal orientation through a horizontal oscillation axis, ensuring safe loading and unloading operations by adapting to container inclination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If roll-off containers are designed for loading and transport with considerable inclination (more than 40°), then the container can be easily loaded and transported, but hazardous waste storage safety deteriorates due to uncontrolled spillage risks
Solution Approach 1:
The patent applies the dynamics principle by making the containment case oscillating rather than fixed. The containment case is suspended from the front wall via oscillating means, allowing it to dynamically adjust its orientation relative to the container body during inclination. This dynamic adaptation enables the containment case to maintain a substantially horizontal position even when the container is inclined at more than 40° during loading and transport, thus resolving the contradiction between ease of operation and storage safety.
2Reliability
If double-walled hermetic containers with spillage recovery systems are used to ensure hazardous waste safety, then storage safety is improved, but implementation and management costs increase significantly
Solution Approach 1:
The patent extracts the essential safety function from complex double-walled hermetic containers with spillage recovery systems. Instead of using the entire complex system, the invention isolates and implements only the critical orientation-maintenance function through the oscillating containment case. This extraction achieves hazardous waste storage safety without the high costs and complexities of double-walled construction and spillage recovery systems.
3Reliability
If double-walled hermetic containers are used to prevent spillage, then storage safety is improved, but the footprint increases and the amount of waste that can be received is limited
Solution Approach 1:
The patent extracts only the essential orientation-maintenance function from the bulky double-walled hermetic container system. By implementing a simple oscillating containment case suspended from the front wall, the invention achieves spillage prevention without the additional volume and footprint of double-walled construction, thereby maximizing the waste reception capacity of the container.

AI summary
A roll-off container for storing sorted waste is described, comprising a substantially parallelepiped-shaped containment case (2), having a front wall (3) arranged transversal to a direction of longitudinal extension (L) thereof and bearing a lifting hook (11) integral therewith, configured to engage to a piece of equipment for loading the containment case (2) on a vehicle bed. The container (1) is provided with at least one hazardous waste collection unit (9) with a plurality of pull-out receptacles (14) engaged to an oscillating structure (12). The oscillating structure is in turn engaged within the containment case (2), rotating about a horizontal oscillation axis (X) perpendicular to the direction of longitudinal extension (L) and positioned above relative to the centre of gravity (G) of the oscillating structure itself bearing the pull-out receptacles. It is therefore possible to load and unload the container on and from the vehicle, while maintaining a substantially horizontal orientation of the pull-out receptacles.
