Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mud flap assemblies for vehicles are prone to corrosion and damage from environmental factors and road debris, leading to increased complexity, cost, and weight, which are not adequately addressed by current systems.
Innovation Solution
A mud flap assembly design featuring a bracket with a core and bands made of different materials, including fiber-reinforced plastics, and support arms with ribs, which are cantilevered and integrally formed with the mud flaps to resist corrosion and deflection, ensuring the mud flaps remain attached during forces applied.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional metal components are used in mud flap assemblies, then strength and durability are improved, but corrosion resistance deteriorates due to exposure to sand, gravel, chemicals, and moisture
Solution Approach 1:
The patent applies composite materials by using fiber-reinforced plastic (FRP) for the support arms and bracket components. The FRP material combines glass or carbon fibers with a polymer matrix to achieve both high strength and excellent corrosion resistance, eliminating the corrosion problem associated with traditional metal components while maintaining structural integrity.
Solution Approach 2:
The patent changes the material parameters by transitioning from metallic materials to polymer-composite materials. This parameter change involves selecting materials with specific tensile strength, elongation, and corrosion resistance properties that optimize performance in the harsh environmental conditions while reducing weight.
2Ease of repair
If multiple separate components are used in mud flap assemblies, then ease of repair is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the mud flap assembly into distinct modular components: the bracket assembly (with integrated support arms) and the mud flap panel. This segmentation allows the mud flap to be easily replaced independently while maintaining a relatively simple overall structure that reduces assembly complexity.
3Strength
If heavier materials are used to resist forces applied to mud flaps, then strength is improved, but weight increases
Solution Approach 1:
The patent uses fiber-reinforced plastic materials that provide high strength-to-weight ratio. The glass or carbon fibers embedded in the polymer matrix deliver exceptional tensile strength and force resistance while being significantly lighter than traditional metal components, thus reducing overall assembly weight without compromising strength.
Solution Approach 2:
The patent applies local quality by varying the thickness and fiber orientation of the FRP components in different regions. The support arms and bracket have increased thickness and optimized fiber alignment in high-stress areas to resist applied forces, while maintaining thinner sections in low-stress areas to minimize weight.
