Asymmetric Caster Wheel Skirt for Locking Mechanism Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caster wheels often interfere with locking mechanisms and are vulnerable to debris such as strings and cables, which can jam the wheel or cause damage, and existing skirts either interfere with the locking mechanism or are prone to jamming.
Innovation Solution
A skirt assembly that fits over the caster wheel, leaving one side free for the locking mechanism, with a design that includes a first and second arm portion, a transverse member, and a skirting clamp, allowing for easy replacement of the skirting material and preventing debris from wedging between the caster and the floor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a traditional caster skirt is used to protect the wheel from debris, then the protection effect is improved, but the locking mechanism operation is interfered with
Solution Approach 1:
The skirt is divided into a first arm portion and a second arm portion that are joined together, creating an open structure that does not fully encircle the wheel. This segmentation allows the locking mechanism to access the wheel while still providing debris protection through the extended arm portions
Solution Approach 2:
The skirt employs asymmetric design where the first and second arm portions are positioned to leave one side of the wheel exposed for locking mechanism access, while the other sides provide protection. The transverse member connects the arm portions asymmetrically to maintain both protection and accessibility
2Object-affected harmful factors
If a traditional caster skirt is used to protect the wheel, then debris protection is improved, but the skirt itself becomes vulnerable to jamming by string and fine debris
Solution Approach 1:
The skirting material is attached to the transverse member and arm portions, creating a flexible barrier that can deflect debris while maintaining structural integrity. This flexible configuration prevents string and fine debris from becoming trapped and jamming the mechanism
Solution Approach 2:
The segmented arm structure with spaced portions creates gaps that allow debris to pass through or deflect rather than accumulate, reducing the risk of jamming while maintaining protective coverage
3Strength
If the skirting material is permanently attached to the skirt structure, then structural integrity is improved, but replacement and maintenance become difficult
Solution Approach 1:
The skirting material is attached to the transverse member and arm portions in a modular fashion, allowing individual sections to be replaced without replacing the entire skirt structure. This segmented attachment maintains structural integrity while facilitating easy maintenance
Solution Approach 2:
The attachment system allows the skirting material to be dynamically attached and detached from the transverse member, enabling easy replacement when worn while maintaining a secure connection during operation

AI summary
The present disclosure relates to caster wheels having a skirt, specifically a skirt which fits over one side of the wheel only, and thus does not interfere with the actuation of a caster wheel locking mechanism.
