Adjustable Fender Arch Support for Work Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fender structures for work machines lack adjustable features, requiring alteration of the support arm's position or location to accommodate different wheel configurations, which is inconvenient and limits flexibility.
Innovation Solution
A fender arch support with a frame part and adjustable components, allowing for adjustable positioning and locking mechanisms, such as complementary toothings and crimp connections, enabling the fender arch to be easily aligned with the work machine wheel without altering the support arm's position, and made from lightweight, corrosion-resistant plastic materials like fibre-reinforced polypropylene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support arm's position or location is altered to accommodate different wheel configurations, then the fender structure can be adapted to different wheels, but the adjustment process becomes inconvenient and complex
Solution Approach 1:
The arch support is divided into a frame part and a separate adjustment part. The adjustment part can be positioned at different locations along the frame part, allowing the fender arch position to be adjusted without modifying the support arm. This segmentation enables independent adjustment of the fender position while keeping the support arm fixed.
Solution Approach 2:
The adjustment part is designed to be movable relative to the frame part, allowing dynamic repositioning of the fender arch along the frame part. This dynamic capability enables the fender to adapt to different wheel configurations while maintaining a fixed support arm installation.
2Strength
If a metal fender arch support is used, then the structure provides sufficient strength and durability, but the overall weight of the fender structure increases
Solution Approach 1:
The arch support frame part is made from fibre-reinforced plastic material, which combines the strength characteristics of fibres with the lightweight properties of plastic. This composite material provides sufficient structural strength while significantly reducing the weight compared to traditional metal supports.
Solution Approach 2:
The material properties of the arch support are changed from metal to fibre-reinforced plastic, altering the density and strength-to-weight ratio parameters. This material substitution maintains structural integrity while reducing the overall weight of the fender assembly.
3Duration of action of stationary object
If traditional metal materials are used for the arch support, then the structure provides durability, but the service life is reduced due to corrosion from mud and water exposure
Solution Approach 1:
The fibre-reinforced plastic material used in the arch support frame part inherently resists corrosion from mud and water exposure. Unlike metal materials that rust and degrade, the plastic composite maintains its structural properties even after prolonged exposure to harsh environmental conditions, thereby extending the service life of the fender structure.
Solution Approach 2:
The use of corrosion-resistant plastic material eliminates the need for protective coatings or anti-corrosion treatments that would otherwise be required for metal components. This material choice directly addresses the harmful effect of corrosion without requiring additional protective measures.
