Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing glide floors in retail environments require a steep angle to facilitate sliding, wasting space, and suffer from creeps that increase friction, making them inefficient and difficult to clean.
Innovation Solution
A glide floor with an arch-shaped rib structure and shallow angle (4°-8° from horizontal) that minimizes contact area and uses low-friction materials, allowing for efficient sliding and easy cleaning, and is designed to be modular for various shelf sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the glide floor is positioned at a steep angle (10° or more from horizontal), then containers can slide along the glide floor effectively, but valuable display space is wasted
Solution Approach 1:
The patent changes the angle parameter of the glide floor from the conventional 10° or more to a shallower angle of 2° to 8° from horizontal. This parameter change is made possible by the rib structure design that reduces creep, allowing the glide floor to function effectively at smaller angles and thus maximize display space while maintaining sliding functionality
Solution Approach 2:
The patent introduces ribs with radiused uppermost tangency points and arch-shaped cross sections. These curved surfaces minimize contact area between the rib and container bottom, reducing friction and creep. The curvature allows containers to slide smoothly at shallower angles without requiring the steep 10°+ angles of conventional flat or angular rib designs
2Device complexity
If conventional angular ridge designs are used, then the glide floor structure is simple, but creep increases friction and reduces sliding functionality
Solution Approach 1:
The patent replaces conventional angular ridge designs with ribs featuring arch-shaped cross sections and radiused uppermost tangency points. These curved surfaces minimize the contact area between the rib and the bottom surface of containers, thereby reducing creep and friction. This design maintains structural simplicity while dramatically improving sliding smoothness and functionality
3Ease of manufacture
If angular intersection areas are present in the ridge design, then manufacturing is straightforward, but cleaning becomes difficult and appearance deteriorates
Solution Approach 1:
The patent eliminates angular intersection areas by designing ribs with arch-shaped cross sections and radiused uppermost tangency points. These curved surfaces eliminate sharp corners and crevices where dirt and residue would accumulate, making the glide floor easy to clean while maintaining straightforward manufacturing processes
Solution Approach 2:
The patent converts the potential harm of complex curved rib structures into a benefit by demonstrating that these arch-shaped designs with radiused tangency points simultaneously achieve multiple goals: they reduce creep for better sliding, eliminate hard-to-clean angular intersections, and can still be manufactured efficiently using conventional molding techniques
4Ease of manufacture
If the glide floor uses conventional materials and designs, then initial cost is lower, but friction increases over time due to creep
Solution Approach 1:
The patent employs ribs with arch-shaped cross sections and radiused uppermost tangency points that minimize contact area and reduce creep. This geometric design, combined with appropriate material selection including slip agents, maintains low friction and high sliding functionality over extended periods, significantly improving the operational lifespan of the glide floor
Solution Approach 2:
The patent incorporates slip agents into the glide floor material composition to reduce the coefficient of friction. This composite approach, combining the structural rib design with friction-reducing materials, ensures long-term functional longevity by preventing the increase in friction that would otherwise occur due to creep in conventional designs
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 solution enables efficient use of space, reduces friction, and maintains sliding functionality even at shallow angles, while being easy to clean and durable, enhancing product display and longevity.
Implementation Method 1
The radiused tangency points of the ribs serve to minimize the contact area between the rib and a bottom surface of each package or container
Implementation Method 2
The glide floor is positioned at an angle in the range of 4° to 8° from horizontal, and preferably at an angle of about 6° from horizontal for a conventional merchandising application, such that a package or container will slide downwardly along the glide floor under the force of gravity
Implementation Method 3
The glide strip includes a slip agent that provides a low coefficient of friction between the glide strip and articles supported on the glide strip

AI summary
A glide floor for use in supporting a number of containers, e.g. for retail display, includes a series of ribs on a top surface defined by the glide floor, in combination with a series of valleys between the ribs. Each rib defines a radiused uppermost tangency point that serves to minimize the contact area between the rib and a bottom surface of each container while providing smooth contact with the bottom surface of the container.
