Modular Waste Container Rim for Detachable Trunnions and Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large waste collection containers face challenges in efficient stacking and modular component replacement due to protruding trunnion devices, leading to increased transport costs and limited stacking height, while also lacking flexibility in attaching additional components like handles and communication devices.
Innovation Solution
A receiving device is integrated into the upper edge of the container body, allowing for detachable attachment of additional components such as handles, trunnion devices, and communication modules through a plug-in connection using receiving profile elements and fastening devices, enhancing stability and manageability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trunnion devices are firmly attached to the side wall of the container body, then the container can be properly lifted and emptied by waste collection vehicles, but the container bodies can only be stacked in insufficient numbers due to the protruding trunnion elements
Solution Approach 1:
The container body is divided into a permanent base structure and removable modular components. The trunnion device is separated from the container body as a detachable module that can be mounted only when needed for waste collection operations, allowing the container to be stacked efficiently when not in use.
Solution Approach 2:
The attachment state of the trunnion device changes dynamically between operational mode (attached) and storage/transport mode (detached). This dynamic configuration allows the container to adapt its structure based on functional requirements, optimizing both lifting capability and stacking efficiency at different times.
2Adaptability or versatility
If individual container components are manufactured separately and assembled later, then components can be replaced if damaged or for different applications, but the number of components per stack is reduced
Solution Approach 1:
The container system is segmented into a permanent container body and interchangeable functional modules (trunnion devices, handle elements). These modular components can be independently replaced or exchanged based on damage or different application requirements, while maintaining compact stacking when not in use.
Solution Approach 2:
The modular components are designed with standardized interfaces that allow them to be used across different container models or applications. A single trunnion device module can potentially serve multiple container bodies, increasing overall system versatility while improving stacking efficiency.
3Reliability
If trunnion devices protrude far from the side wall, then the lifting device can properly grip and tilt the container, but transport costs increase due to limited stacking height
Solution Approach 1:
The lifting interface is segmented into a permanent mounting structure on the container body and a removable trunnion module. When detached for transport, the protruding elements are removed, allowing containers to be stacked to full height capacity and reducing transport costs while maintaining lifting functionality when attached.

AI summary
The present invention relates to a large waste collection container (10) with a capacity of up to 1,700 litres, in particular with a capacity of 1,100 litres, comprising a container body (11), having a container bottom (18), a side wall (12) projecting upwards from the container bottom (18), an insertion opening (20) which is formed at the upper end of the side wall (12) and which is delimited by an upper edge (19) of the container body (19), and a drive gear (26), which comprises a plurality of wheel devices (27), in particular four wheel devices (27), the wheel devices (27) being arranged in the region of the container bottom (18) on the side wall (12) or below the container bottom (18) and extending below the container bottom (18). In order to allow additional container components to get alternatively connected to the container body (11), at least one receiving device (30) is arranged or formed on the upper edge (19) or in the region of the upper edge (19) of the container body (11) for selectively receiving and in particular detachably holding additional container components. The receiving device (30) has at least one receiving profile element (31, 32) which is provided for receiving and holding the additional container components on the container body (11). Furthermore, the receiving profile element (30) has a fastening device for fastening the additional container component, in particular in a detachable manner.
