Waste Collection Arm Tilting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing waste collection systems face challenges with heavy, large containers stored underground, as they require oversized and heavy arm and tilting mechanisms to manage the increased loads, leading to space constraints and instability risks during tilting.
Innovation Solution
The system features tilting means with independent tilting driving mechanisms directly supported on the vehicle's substructure, allowing moments to be transferred to the vehicle's construction parts, while the arm remains lightweight and focused on lifting and transferring the container, separate from the tilting function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If the arm and tilting means are designed to handle heavy loaded containers stored underground, then the container can be tipped and emptied, but the arm and tilting means become considerably heavier and take up more space
Solution Approach 1:
The system separates the tilting function from the arm structure by introducing independent tilting means with their own driving mechanism. The tilting means are directly supported on the vehicle substructure, while the arm only performs lifting and transferring functions. This segmentation allows the arm to remain lightweight while the vehicle structure handles the tilting loads.
Solution Approach 2:
The tilting function is extracted from the arm structure and implemented as a separate system directly integrated with the vehicle. The tilting means with independent driving means are taken out from the arm's functional requirements and directly supported on the substructure, eliminating the need for the arm to be oversized to handle tilting moments.
2Force
If the arm and tilting means are designed to handle heavy loaded containers stored underground, then the container can be tipped and emptied, but the space taken up by oversized parts is considerable, restricting the size of the waste collection area
Solution Approach 1:
By segmenting the tilting function from the arm structure and directly supporting the tilting means on the vehicle substructure, the system eliminates the need for oversized arm components. This allows the waste collection area to be more compact and better utilized, as the arm can be smaller and lighter without compromising the ability to handle heavy containers.
3Ease of operation
If the container is connected to the arm with downward-pointing hooks and lifted into the hooks, then the container can be tilted to empty it, but the forces between the container, hook and arm increase, creating risk of the container coming loose and swinging uncontrollably
Solution Approach 1:
The tilting function is extracted from the arm-container connection system. Instead of using the arm's lifting action to tilt the container, the system employs independent tilting means directly supported on the vehicle. This separation reduces the forces at the arm-container connection point, minimizing the risk of the container coming loose or swinging uncontrollably during tilting operations.

AI summary
A waste collection system comprises at least one container (2) in which waste can be accommodated, a vehicle (1) with a drivable substructure (5), a waste collection area (26) on the substructure (5) and a handling mechanism with an arm (6) for transferring the waste container (2) from an area (41) next to the substructure (5) to a position close to the loading opening (27) of the waste collection area (26). Tilting means (28) with a tilting driving means (31) provide for tilting the container (2) in relation to the waste collection area (26) for emptying the waste from the container (2) into the loading opening (27) of the waste collection area (26). The container (2) and arm (6) are provided with a connecting mechanism (17; 25, 32) for connecting the container (2) with the arm (6). To avoid overloading the arm (6), the tilting means (28) are directly supported on the substructure (5) and the tilting driving means (31) interacts directly with the substructure (5).
