Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional wheel arch design is used, then wheel access and steering function are provided, but structural support and load bearing capability are insufficient
Solution Approach 1:
The wheel arch is merged with the vehicle chassis structure to form an integrated structural component. The wheel arch includes load-bearing mounting points that are structurally integrated into the chassis, combining the wheel arch function with structural support function into a single unified component system.
Solution Approach 2:
The wheel arch is designed to perform multiple functions: it provides wheel housing and access, enables steering movement, and simultaneously serves as a structural load-bearing component. The mounting points are designed to bear forces from suspension and drive components, making the wheel arch a multi-functional element that reduces overall vehicle design complexity.
2Strength
If separate strut towers and force dissipation arrangements are provided, then load bearing capability is ensured, but assembly complexity and manufacturing cost increase
Solution Approach 1:
The wheel arch is merged with the chassis structure, eliminating the need for separate strut towers and force dissipation arrangements. The wheel arch itself becomes the structural element that dissipates forces from suspension and drive components directly to the chassis, reducing the number of separate components and simplifying assembly.
Solution Approach 2:
The separate force dissipation arrangements and strut towers are extracted from the vehicle design and integrated into the wheel arch structure. This extraction eliminates unnecessary intermediate components and allows forces to be transmitted directly from the wheel arch to the chassis through integrated mounting points.
3Adaptability or versatility
If traditional wheel arch design is used, then wheel access is provided, but adaptability for modern manufacturing techniques and electric vehicles is limited
Solution Approach 1:
The wheel arch is designed as a modular component with standardized mounting points that can be independently assembled. This segmentation allows the wheel arch to be manufactured using modern robotic manufacturing techniques and assembled into the vehicle chassis efficiently, reducing assembly time and increasing adaptability to different vehicle configurations including electric vehicles.
