Modular Wheel Assembly With Interchangeable Faces for Weight Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The automotive wheel industry faces challenges in reducing unsprung weight while maintaining aesthetic appeal and customization options, as current designs are often limited by the need to balance weight-bearing components with decorative elements, leading to increased manufacturing costs and restricted design flexibility.
Innovation Solution
A modular wheel system featuring a base wheel with an adaptive hub attachment that allows for interchangeable ornamental faces and center hub attachments, enabling easy customization and weight reduction by distributing weight-bearing material efficiently, while maintaining the appearance of a center lock wheel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If traditional integrated wheel design is used, then structural integrity and weight-bearing capacity are maintained, but weight reduction and design flexibility are limited
Solution Approach 1:
The wheel is divided into three main segments: a base wheel (weight-bearing component), an attachment assembly (connection mechanism), and an ornamental face plate (aesthetic component). This segmentation allows each part to be optimized independently - the base wheel for strength and weight reduction, and the face plate for aesthetic flexibility without compromising overall structural integrity.
2Adaptability or versatility
If traditional integrated wheel design is used, then manufacturing simplicity is maintained, but manufacturing cost and design customization are increased
Solution Approach 1:
By separating the wheel into modular components (base wheel, attachment assembly, face plate), the system enables easy customization of the face plate while the base wheel and attachment assembly can be manufactured once and reused. This reduces overall manufacturing complexity despite increased design flexibility.
Solution Approach 2:
The attachment assembly serves multiple functions: it connects the face plate to the base wheel, provides a mechanism for easy removal and replacement, and maintains structural integrity during vehicle operation. This multi-functionality reduces the need for multiple specialized components.
3Shape
If ornamental face plate is added to base wheel, then aesthetic appeal and design flexibility are enhanced, but device complexity is increased
Solution Approach 1:
The ornamental face plate is extracted as a separate, removable component from the traditional integrated wheel design. This allows the aesthetic elements to be changed independently without affecting the structural base wheel, simplifying the overall system architecture despite the added customization capability.
Solution Approach 2:
The wheel design transitions from a static, fixed configuration to a dynamic, reconfigurable system where the face plate can be easily removed and replaced. The attachment assembly enables this dynamic reconfiguration while maintaining structural integrity during normal operation.

AI summary
A wheel assembly that provides a simulated center lock wheel look that also enables exchanging of ornamental face plates with a center hub attachment device that will allow car enthusiasts to easily change the look of their automotive wheels while maintaining a center lock wheel appearance. The assembly includes three components: a base wheel, a plurality of ornamental face plates, and a center hub attachment extending from one of either the hub or the ornamental face plate.
