Adjustable Refuse Tipper Mounting for Multi-Container Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing refuse vehicle lifting systems struggle with accommodating waste containers of varying sizes and orientations, requiring significant manual adjustment and labor to ensure efficient emptying, and lack removability and serviceability.
Innovation Solution
An adjustable refuse container tipping device with a mounting plate assembly that allows for vertical and lateral adjustment of a grapple arm via slots and fasteners, enabling customization to fit different waste containers and chassis heights, and is removable for maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed mounting system is used for the grapple arm, then the structure is simple and robust, but it cannot accommodate waste containers of varying sizes and orientations
Solution Approach 1:
The mounting system transitions from a fixed structure to an adjustable one by incorporating slots in the mounting plates that allow the grapple arm position to be dynamically changed. The fasteners can be repositioned along these slots to accommodate different container sizes and orientations, making the system adaptable while maintaining structural integrity.
Solution Approach 2:
The mounting system is divided into separate components (mounting plates, fasteners, slots) that can be independently adjusted. This segmentation allows the grapple arm position to be customized without redesigning the entire mounting structure, resolving the contradiction between adaptability and complexity.
2Productivity
If manual adjustment is required for different waste containers, then the system can be simple in structure, but significant manual labor and time are required
Solution Approach 1:
The adjustable mounting system with slots and repositionable fasteners enables quick adaptation to different container types without requiring complex manual adjustments. The operator can simply move the fasteners along the slots to the appropriate position, significantly reducing the time and effort needed while maintaining high emptying efficiency.
3Ease of repair
If the lifting assembly is permanently mounted, then the structure is stable and robust, but it lacks serviceability and removability
Solution Approach 1:
The lifting assembly is segmented into removable components (grapple arm, mounting plates, fasteners) that can be easily detached and reattached. This segmentation provides excellent serviceability while maintaining mounting stability through the use of robust fastening mechanisms that ensure secure connection during operation.
Solution Approach 2:
The mounting system transitions from a permanent fixed structure to a dynamically removable and reattachable system. The slots and fasteners allow the grapple arm to be easily removed for maintenance or replacement while ensuring stable mounting when assembled, resolving the contradiction between serviceability and structural strength.

AI summary
A refuse container tipping device includes a first mounting plate, a second mounting plate, a hinge plate, and a plurality of fasteners. The first mounting plate defines a plurality of first slots. The plurality of first slots each extend in a first direction along substantially parallel axes. The second mounting plate is releasably coupled to the first mounting plate and defines a plurality of second slots. The plurality of second slots each extend in a second direction along substantially parallel axes. The first direction is perpendicular to the second direction. The hinge plate is coupled to the second mounting plate. The hinge plate supports a hinge and a grapple arm that is rotatably coupled to the hinge. The plurality of fasteners couple the second mounting plate to the first mounting plate by extending through the plurality of first slots and the plurality of second slots.
