Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Cargo bodies manufactured separately from vehicle chassis are not easily adaptable to third-party chassis designs, leading to inadequate support and incorrect positioning, and insufficient ground clearance.

Innovation Solution

A refuse body adapter system comprising a sub-frame assembly, sub-frame adapter, and spacer, which allows for adjustable thickness to accommodate different gap sizes between the sub-frame assembly and adapter, ensuring proper alignment and support on various chassis designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If cargo bodies are manufactured separately from vehicle chassis to allow independent production, then manufacturing flexibility and ease of manufacture are improved, but adaptability to different chassis designs deteriorates

Engineering Contradiction:

Improveindependent production of cargo bodiesVSAvoidadaptability to third-party chassis designs

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The mounting system is divided into separate components: a sub-frame assembly that attaches to the cargo body, an adapter assembly that attaches to the chassis, and an adjustable spacer connecting them. This segmentation allows each component to be independently manufactured while maintaining adaptability through the modular connection system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The adapter assembly is designed with universal mounting features that can interface with multiple chassis designs. The adjustable spacer provides multi-functionality by accommodating various gap sizes, allowing the same basic assembly to work across different vehicle platforms and chassis configurations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If cargo bodies are designed for a single chassis design, then structural support and positioning are optimized, but ease of adaptation to other chassis designs deteriorates

Engineering Contradiction:

Improvestructural support and positioning accuracyVSAvoidease of adaptation to third-party chassis

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The spacer incorporates adjustability mechanisms that allow the mounting system to dynamically adapt to different gap sizes between the sub-frame assembly and various chassis designs. This dynamic adjustment capability maintains reliable structural support while enabling adaptation to multiple chassis platforms.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If an adjustable spacer is added to accommodate different gap sizes, then adaptability to different chassis designs is improved, but device complexity increases

Engineering Contradiction:

Improveaccommodation of different gap sizesVSAvoidcomplexity of mounting system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The adjustable spacer serves as an intermediary element between the sub-frame assembly and the adapter assembly. It mediates the connection by accommodating various gap sizes, thereby simplifying the overall mounting process and reducing the complexity of designing multiple custom mounting systems for different chassis.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A refuse body adapter includes a sub-frame assembly, a sub-frame adapter, and a spacer. The sub-frame assembly is configured to be coupled to a cargo body. The sub-frame adapter is configured to be coupled to a chassis of a vehicle. The spacer is coupled to both the sub-frame assembly and the sub-frame adapter. The spacer is disposed in a gap formed between the sub-frame assembly and the sub-frame adapter. A thickness of the spacer may be adjusted to accommodate different gap sizes between the sub-frame assembly and the sub-frame adapter.
