Farm Implement Track Assembly for Uneven Terrain Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile farm implements face stress and increased wear due to inability of track assemblies to conform to uneven terrain, leading to potential failure and crop damage from deviating from the tow vehicle's path.
Innovation Solution
A track assembly with pivotable components, including camber and tilt arms, idler wheels, bogie wheels, and a tensioner arm, allowing the track to adapt to terrain changes and maintain alignment with the tow vehicle, featuring multiple pivot axes and adjustable bogie wheels to ensure contact with the ground surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the track assembly uses a rigid structure to maintain stability, then the structural strength is improved, but the ability to conform to uneven terrain deteriorates
Solution Approach 1:
The track assembly is divided into multiple independent segments including camber arms, tilt arms, idler wheels, and bogie wheels, each capable of independent movement. This segmentation allows the track to adapt to terrain variations while maintaining overall structural integrity through the interconnected pivot connections.
Solution Approach 2:
The track assembly incorporates multiple pivot points and movable components that enable dynamic adjustment to terrain changes. The camber arms can tilt laterally, the tilt arms can pivot vertically, and the bogie wheels can move independently, creating a dynamic system that continuously adapts to uneven ground while maintaining structural strength.
2Adaptability or versatility
If the track assembly uses multiple pivotable components to conform to terrain, then the adaptability to terrain is improved, but the device complexity increases
Solution Approach 1:
Multiple pivotable components including camber arms, tilt arms, idler wheels, and bogie wheels are merged into a single integrated track assembly structure. This consolidation allows the complex terrain-adaptation functionality to be achieved through coordinated movement of interconnected parts rather than separate systems, managing complexity through unified design.
Solution Approach 2:
The pivotable components serve multiple functions simultaneously - the camber arms provide both lateral tilting for terrain adaptation and structural support, the tilt arms provide vertical pivoting and link to the idler wheels, and the bogie wheels provide both ground contact and independent movement capability. This multi-functionality reduces the need for additional specialized components.
3Device complexity
If the track assembly uses fixed wheels to maintain structural simplicity, then the device complexity is reduced, but the ability to follow terrain contours deteriorates
Solution Approach 1:
The wheels are transformed from fixed to dynamic components with multiple degrees of freedom. The idler wheels can pivot on the tilt arms, and the bogie wheels can move independently on their respective arms, allowing the wheel assembly to dynamically conform to terrain variations while maintaining a relatively simple overall structure through the use of basic pivot connections.

AI summary
A track assembly for assisting in moving a farm implement along a ground surface in a line of travel is provided. The track assembly includes a tilt arm comprising front and rear ends. The track assembly includes a camber arm coupled to the tilt arm such that the camber arm permits the tilt arm to pivot about a first axis perpendicular to the line of travel and a second axis parallel to the line of travel. The camber arm is located between the front and rear ends of the tilt arm.
