Partial Wheel Cladding via Adhesive Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle wheel designs often compromise aerodynamics and fuel efficiency due to full-face claddings that cover the entire wheel surface for aesthetic purposes, increasing weight and cost, while also being labor-intensive and prone to damage.
Innovation Solution
A decorative wheel cladding that covers only a portion of the wheel's exterior surface, using a metal-plated structure that is permanently attached via adhesive, allowing for aerodynamic design without sacrificing aesthetics and reducing material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a full-face cladding is used to cover the entire wheel surface for aesthetic purposes, then wheel aesthetics are improved, but wheel weight increases and aerodynamic performance deteriorates
Solution Approach 1:
The cladding is divided into multiple separate components (center cap, spoke claddings, rim cladding) that can be independently attached to different portions of the wheel, allowing aesthetic enhancement without requiring complete wheel coverage
Solution Approach 2:
The cladding components are selectively positioned on specific high-visibility areas of the wheel (center cap, spoke faces, rim edges) to provide aesthetic enhancement where it matters most while leaving other areas exposed for weight reduction and aerodynamic benefits
2Shape
If a full-face cladding is used to cover the entire wheel surface, then wheel aesthetics are improved, but manufacturing cost and labor intensity increase
Solution Approach 1:
The wheel cladding system is segmented into multiple independent components that can be manufactured separately using standard processes and then assembled on the wheel, reducing manufacturing complexity compared to producing a single large custom cladding piece
Solution Approach 2:
The modular cladding components can be used across different wheel designs and vehicle models, allowing for standardized manufacturing processes and reduced tooling costs
3Shape
If a full-face cladding is used to cover the entire wheel surface, then wheel aesthetics are improved, but the cladding becomes more susceptible to damage from curbside contact
Solution Approach 1:
The cladding is extracted from being a continuous full-face covering and instead applied only to specific portions of the wheel, reducing the total surface area exposed to potential damage from curbside contact
Solution Approach 2:
The cladding is strategically positioned on areas less susceptible to curb contact damage while leaving the lower wheel portions exposed, providing aesthetic enhancement without compromising durability
4Weight of moving object
If material is removed from wheel spokes or backsides to reduce weight, then wheel weight decreases, but aerodynamic performance is not optimized
Solution Approach 1:
The cladding components are strategically shaped and positioned to fill gaps and smooth airflow paths in critical aerodynamic zones (spoke leading edges, rim edges) while allowing weight reduction in less critical areas through selective coverage

AI summary
A wheel assembly including a cover portion permanently attached to a wheel. The wheel includes a wheel central hub portion, a wheel outer peripheral rim portion, a plurality of wheel spoke portions extending between the wheel central hub portion and the wheel outer peripheral rim portion, and a plurality of wheel turbine openings disposed between adjacent ones of the plurality of wheel spoke portions. A cover portion is configured to overlie a portion of the wheel portion. The cover portion is configured to overlie one or more of the wheel central hub portion; the plurality of wheel spoke portions, and the plurality of turbine openings or the wheel outer periphery. An adhesive is disposed between an outboard surface of the wheel and the inboard surface of the cover portion to permanently secure the cover portion to the wheel portion. When the cover portion is secured to the wheel, substantial portions of the plurality of wheel spokes, the wheel central hub, or wheel outer periphery remain exposed.
