Soft Caster Wheel Cover for Floor Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Caster wheels made from strong materials like metals and hard plastics can damage flooring such as linoleum or hardwood, and may collapse under heavy objects, causing damage to both the object being transported and the flooring.
Innovation Solution
A caster wheel cover made from a soft material, such as vinyl, that is easily mountable and replaceable, which fits over the outer periphery of the caster wheel to prevent damage by providing a protective layer between the wheel and the flooring, using a floor engaging member with adhesive and sidewalls that form a channel to secure the cover in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If caster wheels are fabricated from strong materials like metals and hard plastics, then the strength and load-bearing capacity of the caster wheel is improved, but the flooring surface is marred or permanently damaged
Solution Approach 1:
The patent applies the intermediary principle by introducing a separate cover component that interfaces between the caster wheel and flooring surface. This cover acts as a mediator that absorbs the harmful interaction (wheel contacting floor) while allowing the wheel to maintain its strong material composition for structural integrity. The cover is made of softer material that prevents flooring damage while the underlying wheel retains its strength.
Solution Approach 2:
The patent segments the caster wheel system into two distinct functional components: the structural wheel core (made of strong material for strength) and the protective cover (made of softer material for floor protection). This segmentation allows each component to be optimized independently - the wheel for load-bearing and the cover for floor protection - thereby resolving the contradiction between strength and flooring damage.
2Object-affected harmful factors
If a caster wheel cover is added to protect flooring, then the protection of flooring surface is improved, but the device complexity increases
Solution Approach 1:
The patent employs a flexible cover that conforms to the cylindrical shape of the caster wheel. This flexible shell design provides comprehensive floor protection while maintaining simplicity - the cover can be easily manufactured as a single piece, installed by sliding over the wheel, and removed for replacement without complex fastening mechanisms.
3Object-affected harmful factors
If a caster wheel cover is added to protect flooring, then the protection of flooring surface is improved, but the ease of operation is reduced
Solution Approach 1:
The flexible nature of the cover allows it to deform and flex as the rigid caster wheel rotates, ensuring continuous contact with the flooring surface without interfering with the wheel's rotational motion. This flexibility maintains smooth operation while providing consistent floor protection.
Solution Approach 2:
The cover is designed to dynamically adapt to the wheel's rotation through its flexible material properties. As the wheel turns, the cover flexes and deforms accordingly, maintaining its protective function throughout the entire rotation cycle without creating operational resistance or interference.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The caster wheel cover effectively reduces damage to flooring by providing a cushioned surface for the caster wheel to roll on, allowing for smooth movement of objects without interfering with the wheel's operation and enabling easy replacement when worn.
Implementation Method 1
An adhesive may be provided along the inner surface of the floor engaging member for affixing the floor engaging member to the outer surface of the wheel.

AI summary
A castor wheel cover is provided for mounting on a wheel of a castor wheel assembly. The wheel has an outer surface and the castor wheel cover includes a floor engaging member having inner and outer surfaces. First and second sidewalls projecting from corresponding first and second side edges of the floor engaging member so as to define a channel therebetween. The channel is adapted for receiving the outer surface of the wheel therein.
