Solution Overview

Problem

Aluminum and metal wheels are prone to scratches and costly to replace or repair, and existing wheel protectors are aesthetically unappealing and difficult to install.

Innovation Solution

A segmented wheel protector system comprising snap-fit segments made of polycarbonate or ABS, designed to match the wheel's profile, with adhesive regions for secure attachment, allowing easy installation and concealment of preexisting damage, and accommodating valve stems for aesthetic appeal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional wheel protectors are used, then wheels are protected from scratches and impacts, but the protectors negatively impact the look of the wheels and are difficult to install and remove

Engineering Contradiction:
Improvewheel protection from scratches and impactsVSAvoidease of installation and removal
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The wheel protector is divided into multiple segments that can be independently installed and removed. Each segment fits between wheel spokes and can be separately attached using adhesive, allowing easy installation and removal while maintaining wheel protection. This segmentation directly addresses the ease of operation issue by enabling simple, tool-free installation and removal of individual segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wheel protector segments are designed to match the color of the wheel, making them visually appealing and aesthetically integrated. This color matching resolves the appearance issue by ensuring the protectors do not negatively impact the look of the wheels, while still providing the necessary protection.

Inventive Principle:
Principle #32Color changes

2Object-affected harmful factors

If traditional wheel protectors are used, then wheels are protected from scratches and impacts, but the protectors are difficult to install and remove

Engineering Contradiction:
Improvewheel protection from scratches and impactsVSAvoidcomplexity of installation process
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The wheel protector is divided into multiple segments that can be independently installed and removed. Each segment fits between wheel spokes and can be separately attached using adhesive, allowing easy installation and removal while maintaining wheel protection. This segmentation directly addresses the ease of operation issue by enabling simple, tool-free installation and removal of individual segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The installation mechanism replaces complex mechanical fastening systems with simple adhesive attachment. The segments are designed to be adhered directly to the wheel surface using adhesive, eliminating the need for bolts, clips, or other mechanical fastening components. This substitution dramatically simplifies the installation process while maintaining secure attachment for wheel protection.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If wheel protectors are designed to be secure and durable, then they remain attached during curb rash and impacts, but they become difficult to install and remove

Engineering Contradiction:
Improvesecure attachment during impactsVSAvoidease of installation and removal
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The wheel protector is divided into multiple segments that can be independently installed and removed. Each segment fits between wheel spokes and can be separately attached using adhesive, allowing easy installation and removal while maintaining wheel protection. This segmentation directly addresses the ease of operation issue by enabling simple, tool-free installation and removal of individual segments.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adhesive strength and segment material properties are optimized to provide secure attachment during normal operation and impacts, while still allowing for controlled removal when needed. The segments are designed with specific material characteristics that balance durability during use with ease of removal, resolving the contradiction between reliability and ease of operation.

AI summary

A protector for a wheel is formed from a plurality of segments (100). Each segment is formed from a synthetic material and has an arcuate distal edge (102) of a first radius, the distal edge extending beyond a distal edge of the wheel. Each segment has at least two spoke adjacent edges (106, 108) and an arcuate proximal edge with a second radius less than the first radius. In some embodiments, the proximal edge defines a hook to engage an inner recess of the wheel. Each spoke adjacent edge is configured to reside near a spoke of the wheel during use. In some embodiments, a protrusion extended from the lip serves as a pinch point when a tire deforms during an impact event.
