D-Shaped Wheel Rim Protector for Kerb Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wheel protection devices are ineffective in preventing kerb damage, as they often accumulate dirt and debris, catch on objects, generate noise at high speeds, and require removal for tire or wheel replacement, increasing repair costs and complexity.
Innovation Solution
A vehicle wheel protection device featuring an elongate member with a D-shaped cross-section, attached to the tire or wheel rim using a semi-permanent adhesive, extending perpendicularly from the tire side wall to provide a buffer against kerb damage without overlapping with the wheel rim or tire, made from rigid materials like nylon or ABS, and designed to be easily removable and retrofittable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flap or elongate member is attached to protect the wheel rim, then kerb damage is reduced, but dirt and debris accumulate underneath the device
Solution Approach 1:
The protective device uses a curved elongate member that follows the contour of the wheel rim, creating a smooth aerodynamic shape that prevents dirt and debris accumulation while maintaining protection effectiveness
Solution Approach 2:
The invention extracts the protective function from traditional hubcaps and applies it as a separate elongate member attached to the wheel rim, allowing independent optimization of protection without the drawbacks of hubcap removal and debris trapping
2Reliability
If the protective device extends over the tyre, then wheel protection is improved, but the device catches on passing objects
Solution Approach 1:
The elongate member is positioned asymmetrically on the wheel rim, extending only to the point where it provides protection without overhanging the tyre edge, creating an optimized profile that prevents contact with passing objects while maintaining kerb protection
Solution Approach 2:
The invention optimizes the dimensional parameters of the elongate member, specifically controlling its length and position relative to the wheel rim and tyre, to achieve the balance between protection and avoiding contact with external objects
3Reliability
If a flap is secured to protect the wheel, then kerb damage is reduced, but air forced under the flap generates noise at high speeds
Solution Approach 1:
The curved profile of the elongate member creates a smooth airflow path that prevents air from being forced underneath the device, eliminating the flapping noise that occurs with traditional flat flap designs at high speeds
Solution Approach 2:
The elongate member serves multiple functions: it protects the wheel rim from kerb damage, maintains aerodynamic efficiency by preventing air ingress, and reduces noise, combining several benefits in a single device
4Reliability
If a protective device is attached to the wheel, then kerb damage is prevented, but the device must be removed for tyre or wheel replacement
Solution Approach 1:
The protective device is designed as a separate, independent elongate member that can be attached and removed independently from the wheel and tyre assembly, allowing quick removal during maintenance without affecting the wheel or tyre themselves
