Pivotable Agricultural Trailer Wheel Mount Reduces Frame Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional agricultural equipment mounting assemblies cause undue stress and wear on tool frames due to rigid attachment to wheel assemblies, leading to premature wear and reduced strength, especially when navigating uneven terrain, and can overburden tractor hitches.
Innovation Solution
An agricultural trailer and caddy assembly with a wheel attachment member and tractor-tool attachment frame, featuring a bolster that rotatably connects the wheel attachment member to the tractor-tool attachment frame, allowing for pivotable movement and reducing stress on the tool frame by distributing the load to wheels, thereby alleviating strain on the tractor hitch.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the wheel assembly is rigidly attached to the tool frame, then the equipment provides stable mounting, but the tool frame experiences increased stress and wear due to forces spreading to the outer part of the frame
Solution Approach 1:
The patent applies the dynamics principle by replacing the rigid static attachment with a dynamic pivotable connection. The wheel assembly can rotate relative to the tool frame about a pivot axis, allowing the structure to adapt to uneven terrain and reduce stress transmission to the tool frame while maintaining operational stability.
2Stability of the object's composition
If the wheel assembly is fixed to the tool frame, then the equipment maintains structural rigidity, but premature wear occurs due to bending and stress from uneven terrain
Solution Approach 1:
The pivotable connection allows the wheel assembly to move dynamically relative to the tool frame, absorbing the effects of uneven terrain through rotation rather than transmitting bending stresses through the frame, thereby reducing premature wear while maintaining structural integrity.
Solution Approach 2:
The pivot axis acts as an intermediary element between the wheel assembly and the tool frame. This intermediate connection point allows relative movement and stress distribution, protecting the tool frame from direct exposure to terrain-induced stresses while maintaining the functional connection between components.
3Ease of operation
If the agricultural equipment is supported by the tractor hitch, then the equipment can be moved, but the tractor hitch experiences extra load reducing work capacity
Solution Approach 1:
The pivotable wheel assembly allows the equipment to dynamically adjust its support distribution. By enabling the wheel assembly to rotate and bear more load, the system reduces the static load on the tractor hitch while maintaining ease of operation through the same pivot mechanism.
