Adjustable Header Transport Carrier for Single-Operator Towing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for transporting harvesting headers are cumbersome, often requiring multiple operators and are not adaptable to different header sizes, as they typically involve fixed-size trailers that are difficult for a single operator to manage and maneuver.
Innovation Solution
A system comprising front and rear carriers with steerable wheel assemblies and extendable strap systems that can be securely attached to the harvesting header, allowing for easy towing and alignment with a towing vehicle, enabling a single operator to transport the header efficiently across standard roadways.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed-size trailer is used to transport the header, then the header can be safely transported on public roadways, but the system requires multiple operators and is difficult to maneuver
Solution Approach 1:
The trailer is transformed from a static, fixed-size structure to a dynamic, adjustable platform. The telescoping bed allows the trailer length to be extended or retracted based on the header size, while the adjustable support members can be repositioned to accommodate different header configurations. This dynamic adaptability enables a single operator to safely load and transport various header types without requiring multiple people.
Solution Approach 2:
The trailer is designed with universal features that allow it to handle multiple header types and sizes. The adjustable support members can be positioned at different locations along the trailer bed, and the telescoping mechanism allows the trailer to accommodate both wide and narrow headers. This multi-functionality replaces the need for multiple specialized trailers or operators.
2Strength
If brackets are used as support members, then the header can be secured to the trailer, but the system is not adaptable to various header configurations
Solution Approach 1:
The support members are designed to be adjustable rather than fixed. They can be repositioned along the trailer bed and at different heights to match various header configurations. This dynamic adjustability maintains strong securing capability while adapting to flex type headers, rigid headers, and other variations without requiring specialty brackets.
Solution Approach 2:
The support system is divided into multiple adjustable segments rather than a single fixed bracket structure. Each support member can be independently positioned and adjusted, allowing the system to adapt to different header shapes and sizes while maintaining secure attachment points.
3Length of moving object
If the header is placed lengthwise on the trailer, then it fits within a single lane, but a single operator cannot conveniently manipulate the loading process
Solution Approach 1:
The telescoping bed mechanism allows the trailer to dynamically adjust its length during the loading process. The bed can be extended to provide adequate workspace for the operator, then retracted to optimize transport width. This dynamic adjustment makes it feasible for a single operator to safely and conveniently load wide headers while maintaining road-compliant dimensions during transport.
4Area of moving object
If a large trailer is used to accommodate wide headers, then the header can be transported, but the trailer becomes difficult for a single operator to maneuver
Solution Approach 1:
The telescoping bed allows the trailer to dynamically change its effective size. When not in use, the bed can be retracted to minimize the trailer's footprint and improve maneuverability for a single operator. When needed, it extends to provide the necessary capacity for wide headers, thus resolving the contradiction between transport capacity and ease of operation.
