1Object-affected harmful factors

If a conventional fender flare is used, then the wheel and tire combination can be accommodated, but water spray and mud debris still contaminate the vehicle

Engineering Contradiction:

Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The fender flare is segmented into multiple functional zones: an interior portion with diagonally oriented troughs for water drainage, a top area with gutters for debris channeling, and a retractable mud flap. Each segment performs a specific function to manage different types of contaminants, allowing the system to effectively reduce water spray and mud debris contamination while maintaining a relatively simple overall structure.

Principle #1Segmentation

2Object-affected harmful factors

If the fender flare includes drainage features, then water management improves, but the aesthetic appearance may be compromised

Engineering Contradiction:
Improvewater spray reductionVSAvoidaesthetic appearance
Core Design Contradiction:
Object-affected harmful factorsVSShape

Solution Approach 1:

The drainage features are strategically positioned in specific local areas where they are most effective: troughs are placed in the interior portion facing the wheel well to catch water at its source, while gutters are positioned in the top area to channel debris. This localized placement ensures optimal water management performance while minimizing the visual impact on the overall aesthetic appearance of the fender flare.
