Modular Wheel Assembly With Asymmetric Covers for Airflow Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current car wheels are often designed for one side and used on both sides, leading to unbalanced aerodynamics and potential turbulent airflow, which affects the vehicle's performance and energy efficiency.
Innovation Solution
A wheel assembly with a rim body, two cover elements made of different materials, and a wheel disc element, allowing for individual design and manufacturing for left and right sides to enhance aerodynamics and reduce tooling costs, featuring venting holes for improved airflow and brake ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the same wheel design is used on both left and right sides of the vehicle, then manufacturing costs are reduced and simplicity is improved, but aerodynamic balance deteriorates and turbulent airflow is generated
Solution Approach 1:
The wheel assembly is segmented into three main components: a rim body, a first cover element, and a second cover element. These components can be manufactured separately and assembled differently for left and right sides, allowing aerodynamic optimization while maintaining manufacturing efficiency through modular production
Solution Approach 2:
The first cover element and second cover element are designed with asymmetric configurations tailored for specific sides of the vehicle. The cover elements may include different spoke patterns, opening arrangements, or surface geometries optimized for the respective side's aerodynamic requirements, eliminating the symmetry that causes turbulent airflow
2Ease of manufacture
If the rim body and cover elements are made of the same material, then manufacturing process is simplified, but design flexibility and aerodynamic optimization are reduced
Solution Approach 1:
The wheel assembly utilizes composite construction where the rim body may be made of metal (aluminum or steel) for structural strength, while the cover elements are made of plastic or polymer materials for aerodynamic shaping and cost efficiency. This material differentiation allows each component to be optimized for its specific function while being manufactured through appropriate processes
3Strength
If a single-piece wheel design is used, then structural integrity is improved, but aerodynamic optimization and brake ventilation are compromised
Solution Approach 1:
The wheel assembly is divided into multiple segments including the rim body, first cover element, and second cover element. These segments are connected through attachment mechanisms (such as clips, screws, or interference fits) that maintain structural integrity while allowing airflow to pass through openings in the cover elements for brake ventilation and reduced turbulence
