Modular Protective Wheel Frame for Agricultural Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protective frames for agricultural working vehicles are bulky, heavy, and time-consuming to install, and do not accommodate varying crop heights or configurations.
Innovation Solution
A modular protective wheel frame with a base segment, support elements, and union elements that can be easily assembled and disassembled using removable fixing devices, allowing for adjustable attachment points to stabilize the frame and accommodate different crop heights, featuring a rigid cover for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional protective frames are used, then crop protection function is achieved, but the frames are bulky and heavy
Solution Approach 1:
The protective frame is divided into multiple modular segments (front segment, rear segment, lateral segments) that can be assembled and disassembled independently. This segmentation reduces the weight of individual components and allows selective use of frame portions based on crop height requirements, directly addressing the contradiction between protection effectiveness and frame weight.
2Object-affected harmful factors
If traditional protective frames are used, then crop protection is provided, but installation takes many hours
Solution Approach 1:
The frame's modular segmentation enables rapid assembly and disassembly operations. Each segment can be independently installed or removed, reducing installation time from many hours to a fraction of that time, while maintaining the protective function.
Solution Approach 2:
The frame incorporates adjustable and removable elements that allow dynamic reconfiguration. Attachment points and connection mechanisms enable quick adjustments to accommodate different crop heights without requiring complete frame replacement or lengthy installation procedures.
3Object-affected harmful factors
If traditional protective frames are used, then wheel protection is achieved, but they do not accommodate varying crop heights
Solution Approach 1:
The segmented frame structure allows selective assembly of front, rear, and lateral segments based on specific crop height requirements. Users can configure the frame height by combining different segment portions, providing adaptability across varying crop heights while maintaining protective functionality.
Solution Approach 2:
The frame incorporates adjustable attachment points and removable segments that enable dynamic reconfiguration to match different crop heights. This adaptability allows the same frame system to protect against damage for crops of varying heights, resolving the contradiction between protection effectiveness and versatility.
4Strength
If traditional protective frames are used, then structural strength is provided, but the frames are bulky
Solution Approach 1:
Dividing the frame into modular segments allows optimization of each segment's structural strength-to-volume ratio. Each segment can be designed with precise structural features needed for its specific function, eliminating unnecessary material and reducing overall frame volume while maintaining required strength through strategic placement of connection points and support elements.

AI summary
Disclosed is a protective wheel frame of an agricultural working vehicle and a method for mounting a protective frame on a wheel of an agricultural working vehicle. The protective frames, or line openers, are designed to prevent the wheels of working vehicles from damaging crops during their operation. The protective frame includes a segment configured to surround at least a front portion of a wheel of a working vehicle and a connection element. The protective frame may also include additional frame segments that form a structure to support a rigid covering. The method for mounting the protective frame on a working vehicle wheel includes steps for mounting and coupling segments and connecting elements of the protective frame.
