Mudguard Support with Adjustable Arc and Reinforced Welds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mudguard supports for farm vehicles are insufficient in providing protection, particularly at the front and rear parts of the wheel, and require heavy, thick rectilinear lengths for reinforcement, which can be cumbersome and prone to breakage due to vibrations.
Innovation Solution
The support features an L-shaped arm with a removable fastening system and polygonal reinforcement structure using metal section bars, allowing adjustable positioning of the arcuate support and reinforced welding points to enhance stability and protection without requiring significant adjustments to the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy, thick rectilinear lengths are used for reinforcement, then the strength of the arcuate bar is improved, but the weight and susceptibility to breakage due to vibrations increase
Solution Approach 1:
The patent changes the geometric parameters of the rectilinear lengths by introducing concavities at the corners that are filled with welding material. This modifies the stress distribution and connection strength without increasing the overall dimensions or weight of the reinforcement structure, thereby maintaining strength while improving reliability against vibration-induced breakage
Solution Approach 2:
The patent creates a composite structure by combining the rectilinear lengths with welding material filled in the concavities at the corners. This composite approach enhances the connection between the rectilinear lengths and the arcuate bar, improving resistance to vibration while maintaining the original weight and dimensions
2Object-affected harmful factors
If the mudguard protection is extended to cover all wheel areas, then the protection level is improved, but the complexity and weight of the support structure increase
Solution Approach 1:
The patent applies local quality by providing polygonal reinforcement specifically at the corners of the arcuate bar where stress concentration occurs, rather than uniformly reinforcing the entire structure. This localized approach extends protection to critical areas without unnecessarily increasing overall structural complexity or weight
3Adaptability or versatility
If removable fastening means are provided for adjustable positioning, then the adaptability is improved, but the device complexity increases
Solution Approach 1:
The patent implements dynamics by providing removable fastening means that allow the arcuate support to be positioned at different locations along the L-shaped arm. This creates an adjustable, dynamic system that can adapt to different operational requirements while maintaining relatively simple construction through the use of standard fastening components
