Wheel Hub Guard Structure for Impact Protection and Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wheel hub assemblies and hub caps are fragile and prone to damage, particularly the exposed plastic or aluminum components, necessitating a protective solution that allows for inspection and maintenance access.
Innovation Solution
A hub guard is designed to mount onto a wheel hub assembly, featuring a lower base plate, vertical risers, and an outer deflection component, creating a protective structure around the hub cap while enabling access through strategically positioned openings for inspection and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a protective structure is added around the hub cap, then the strength and damage resistance of the hub cap is improved, but the device complexity increases
Solution Approach 1:
The hub guard is designed as a nested structure that fits over the existing hub cap, with the deflection component extending beyond the hub cap perimeter and the base plate mounting to the hub assembly beneath the hub cap, creating a protective enclosure without replacing the original hub cap
Solution Approach 2:
The hub guard is divided into three distinct components: a deflection component with vertical risers, a base plate with mounting holes, and fasteners, allowing for modular assembly and installation around the existing hub cap while providing comprehensive protection
2Reliability
If the hub guard provides complete coverage around the hub cap, then the protection effectiveness is improved, but the ease of operation for inspection and maintenance deteriorates
Solution Approach 1:
The deflection component includes strategically positioned openings that provide localized access points for inspection and maintenance activities, allowing operators to reach the hub cap through these gaps while the rest of the structure remains intact and protective
Solution Approach 2:
The openings in the deflection component serve as intermediary access points that mediate between the need for complete protection and the need for operational access, allowing tools and hands to reach the hub cap without removing the hub guard
