Adjustable Refuse Vehicle Tipper Mounting for Chassis Height Variations

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing refuse vehicle lifting systems are not adequately adjustable to accommodate different user heights and varying chassis heights due to tire size changes or suspension lifts, which can affect the efficiency and safety of waste collection.

Innovation Solution

The refuse container tipping device features a mounting plate assembly with slotted configurations that allow for adjustable positioning relative to the refuse vehicle, enabling vertical, horizontal, and rotational adjustments to ensure proper alignment and operation regardless of user height or chassis variations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the lifting system uses a fixed mounting position, then the structural design is simple, but it cannot accommodate different user heights and chassis height variations

Engineering Contradiction:

Improveadjustability to user height and chassis heightVSAvoidmounting plate assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting plate assembly incorporates slots that allow the hinge plate to be repositioned dynamically along the slot length, enabling adjustment of the grapple arm's mounting position to accommodate different user heights and chassis variations while maintaining a relatively simple overall structure

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mounting plate assembly is divided into multiple components (first mounting plate, second mounting plate, hinge plate) connected by slots and fasteners, allowing independent adjustment of each segment to achieve the desired position without redesigning the entire structure

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the mounting plate assembly includes multiple slots and fasteners for adjustment, then adaptability improves, but assembly and disassembly time increases

Engineering Contradiction:

Improvepositioning flexibilityVSAvoidassembly and disassembly time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The slots and fasteners enable quick repositioning of the hinge plate without requiring complete disassembly of the mounting assembly, reducing adjustment time while maintaining positioning flexibility

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The slots act as intermediaries that guide the fasteners during assembly, allowing for quick alignment and installation of the hinge plate at different positions without requiring precise manual positioning

Inventive Principle:

Principle #24Intermediary (Mediator)

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.
