Work Vehicle Boom Attachment With Segmented Reinforcement

Solution Overview

Problem

Existing boom assemblies in heavy machinery, such as loaders, face challenges in transmitting substantial mechanical loads without compromising structural integrity, leading to a need for improved mechanical linkage systems that enhance stability and support during lift and manipulation tasks.

Innovation Solution

A structural attachment assembly with opposing connector ends and a support structure featuring a structural reinforcement member, comprising a first and second reinforcement member arranged within an interior cavity, providing increased structural integrity and lifting support by distributing loads effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a conventional boom assembly is used, then the structure is simpler and easier to manufacture, but the structural integrity and lifting capacity are insufficient under substantial mechanical loads

Engineering Contradiction:

Improvestructural integrityVSAvoidstructural complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The reinforcement member is divided into multiple segments (first reinforcement member and second reinforcement member) that are positioned at different locations within the support structure. This segmentation allows the load-bearing function to be distributed across multiple components, enhancing overall structural integrity while maintaining manufacturing feasibility through modular construction

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support structure combines multiple materials including the support structure material, first reinforcement member material, and second reinforcement member material to create a composite structural system. This composite approach enables the assembly to withstand substantial mechanical loads by leveraging the complementary properties of different materials, thereby improving strength without requiring a complete redesign of the entire structure

Solution Approach 1:

The reinforcement member is divided into multiple segments (first reinforcement member and second reinforcement member) that are positioned at different locations within the support structure. This segmentation allows the load-bearing function to be distributed across multiple components, enhancing overall structural integrity while maintaining manufacturing feasibility through modular construction

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first and second reinforcement members are positioned at specific locations within the support structure based on local load requirements. This local quality approach ensures that reinforcement is provided precisely where mechanical loads are transmitted, optimizing stability while avoiding unnecessary complexity in regions where reinforcement is not needed

AI summary

In accordance with an example embodiment, a structural attachment assembly for a work vehicle is disclosed. The structural attachment assembly comprises opposing first and second connector ends. The first connector end is arranged for removable or fixed coupling to a frame of the work vehicle and the second connector end is arranged for removable or fixed coupling to another member of the attachment assembly. A support structure is coupled to and interposedly arranged between the first connector end and the second connector end. The support structure comprises a plurality of walls with inner surfaces defining an interior cavity. The interior cavity comprises a first reinforcement member and a second reinforcement member relatively arranged to form a structural reinforcement member that extends substantially through a length of the interior cavity.
