Low-Friction Kitchen Equipment Coaster for Easy Sliding Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial kitchen equipment is difficult to move, leading to inadequate cleaning and potential strain injuries, and existing casters can snag mop fibers and wear out quickly, especially on uneven floors.
Innovation Solution
A coaster with a cylindrical, high-strength, low-friction thermoplastic body that supports each leg of heavy equipment, featuring a recess for the leg or caster, a drain passage to prevent liquid retention, and rounded edges for smooth movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If casters are provided on kitchen equipment to facilitate movement, then ease of operation is improved, but reliability deteriorates due to mop fibers snagging and wheel wear
Solution Approach 1:
The invention extracts the problematic caster wheel from the system and replaces it with a simple sliding foot. The foot is a basic geometric shape (cylinder or frustum) that slides directly on the floor without rotating components, eliminating the reliability issues of mop fiber snagging and wheel wear while maintaining ease of movement capability
Solution Approach 2:
The invention changes the physical parameters of the moving component by using a low friction material with a specific coefficient of friction range (0.15-0.35). This material parameter change enables smooth sliding movement without the mechanical complexity of casters, resolving the contradiction between ease of movement and reliability
2Device complexity
If ordinary legs are used on kitchen equipment, then device complexity is reduced, but ease of operation deteriorates due to difficulty sliding over tiled and uneven floors
Solution Approach 1:
The invention changes the material parameter of the sliding surface by using a low friction thermoplastic material with coefficient of friction between 0.15-0.35. This parameter change allows the simple structural foot to slide easily over tiled and uneven floors, simultaneously achieving structural simplicity and ease of movement
3Productivity
If heavy commercial kitchen equipment is moved regularly for cleaning, then productivity is improved, but loss of energy increases due to the heavy weight requiring significant effort
Solution Approach 1:
The invention changes the friction parameter at the contact surface by using a thermoplastic material with low coefficient of friction (0.15-0.35). This reduces the force required to initiate and maintain sliding motion, thereby reducing energy loss while enabling more frequent movement for cleaning purposes

AI summary
A coaster for heavy equipment in a commercial kitchen permits easier movement of the equipment for cleaning purposes. The coaster has a rigid, high strength body which includes a recess in the top surface which receives a leg of the heavy equipment, such as a commercial range. The coaster is cylindrical with a rounded lower edge and includes a drain passage between the floor of the recess and the outside of the sidewall. The coaster is made of a low friction polymer which is rugged and chemically resistant, such as polyoxymethylene.
