Pivoting Work Implement Segments for Transport Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Work vehicles with long work implements face challenges during transportation due to height and length constraints, making it difficult to travel on standard highways and trailers without requiring special accommodations.
Innovation Solution
A work vehicle design featuring a boom and arm system that can be pivotally adjusted between a retracted transport orientation and an extended work orientation, allowing the implement to be securely positioned for transportation and operation, with adjustable stops and fasteners to facilitate easy conversion between these positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the work implement is extended to sufficient length for efficient field work, then work efficiency is improved, but the vehicle becomes too long to travel on standard trailers
Solution Approach 1:
The work implement is divided into multiple segments (boom with first and second portions, arm with first and second portions) that can be independently positioned. This segmentation allows the implement to be configured in different orientations - extended for work efficiency and retracted/ folded for transport within standard trailer dimensions.
Solution Approach 2:
The implement incorporates movable joints and pivotable portions that enable dynamic reconfiguration between work and transport configurations. The second portion of the boom and second portion of the arm can be pivoted to different orientations, allowing the implement to adapt its length and shape according to operational or transport requirements.
2Productivity
If the work implement is extended to sufficient length for efficient field work, then work efficiency is improved, but the vehicle becomes too high to travel on some highways
Solution Approach 1:
The implement features pivotable portions (second portion of boom, second portion of arm) that can be dynamically repositioned between extended and retracted orientations. This dynamic capability allows the implement to achieve sufficient height for effective work operations while being able to lower to highway clearance requirements during transport.
3Adaptability or versatility
If the work implement is made retractable for transport, then transportability is improved, but the complexity of the implement structure increases
Solution Approach 1:
The implement is segmented into modular portions (boom with attachable second portion, arm with attachable second portion) that can be independently positioned and secured. This segmentation enables retractability for transport while maintaining a relatively simple overall structure that can be configured as needed without requiring complex mechanisms.

AI summary
A work implement for a work vehicle includes a boom having a chassis attachment end and an arm attachment end, an arm including a boom attachment end and a tool attachment end, and a work tool coupled to the tool attachment end of the arm. The boom attachment end is pivotally coupled to the arm attachment end of the boom. At least one of the boom and the arm includes a first portion and a second portion movably coupled to the first portion between a first orientation with respect to the first portion and a second orientation with respect to the first portion. At least one fastener is coupled between the first and second portions to selectively secure the second portion in the first orientation and the second orientation with respect to the first portion.
