Farm Implement Track Assembly for Uneven Terrain Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing track assemblies for mobile farm implements struggle to effectively conform to uneven terrain, leading to stress on the assemblies and potential failure, and fail to closely follow the path of a tow vehicle, risking crop damage.
Innovation Solution
A track assembly for a farm implement that includes a camber arm, a tilt arm, front and rear idler wheels, and bogie wheels, allowing the track assembly to pivot about multiple axes to adapt to changes in ground surface level and maintain alignment with the tow vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the track assembly uses a rigid structure to maintain stability, then 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 a frame assembly, multiple arm assemblies (first, second, third arm assemblies), and individual wheel assemblies. Each segment can move independently through pivoting joints, allowing the overall structure to maintain strength while adapting to terrain variations. The segmentation enables each component to flex and adjust without compromising the structural integrity of the entire assembly.
Solution Approach 2:
The patent implements dynamic movement capabilities through multiple pivot joints that allow the arm assemblies to rotate and adjust their positions. The first arm assembly pivots relative to the frame, the second arm assembly pivots relative to the first arm, and the third arm assembly pivots relative to the second arm. This dynamic configuration enables the track assembly to continuously adapt to changing terrain conditions while maintaining structural strength through controlled mechanical movement.
2Adaptability or versatility
If the track assembly uses multiple pivoting arms and wheels to conform to terrain, then adaptability to uneven terrain is improved, but device complexity increases
Solution Approach 1:
Multiple functional components are merged into integrated arm assemblies. Each arm assembly combines pivot joints, support structures, and wheel mounting mechanisms into a single unified component. The first arm assembly integrates the pivot connection to the frame, the pivot connection to the second arm, and the support for the first and second wheels. This merging reduces the number of separate parts and simplifies the overall device while maintaining the complex adaptability function.
Solution Approach 2:
The arm assemblies are designed with multi-functionality to reduce overall device complexity. Each arm assembly serves multiple purposes: providing structural support, enabling pivoting motion for terrain adaptation, mounting wheels for ground contact, and transmitting forces between different parts of the track assembly. This universal design approach allows a single component to perform multiple functions that would otherwise require separate mechanisms.
3Device complexity
If the track assembly uses fixed wheels to maintain structural simplicity, then device complexity is reduced, but the ability to follow terrain contours and tow vehicle path deteriorates
Solution Approach 1:
The wheel assemblies are made dynamic through their connection to the multi-level arm pivot system. The wheels are mounted on the third arm assembly, which pivots relative to the second arm assembly, which in turn pivots relative to the first arm assembly, which pivots relative to the frame. This dynamic chain of pivots allows the wheels to automatically follow terrain contours and the tow vehicle path without requiring complex active control systems, achieving adaptability through passive mechanical movement.

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.
