Modular Can Rack Assembly for Stable Gravity-Fed Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing can racks in supermarkets are not designed to accommodate large volumes of cans efficiently, often leading to instability when cans are stacked, making them difficult to remove and display effectively due to limited space and surface area.
Innovation Solution
A stackable can rack assembly with modular racks that utilize flat bars with convex and concave humps and brackets for stability, allowing for multiple configurations and gravity-fed dispensing, enabling easy access and display of cans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If cans are stacked on end on top of each other on ordinary rigid supermarket shelves, then the shelf space is utilized, but the cans do not readily dispense from the shelf and may fall when customers attempt to remove them
Solution Approach 1:
The patent employs curved or sloped shelf surfaces instead of flat horizontal surfaces. The shelves are configured with a downward slope from rear to front, causing cans to naturally roll forward under gravity for easy dispensing while maintaining stable stacking through the curved geometry that guides can placement and retrieval.
Solution Approach 2:
The patent transforms the static can stacking arrangement into a dynamic system where cans can easily move along the sloped shelves. The shelves are designed to facilitate controlled movement of cans during both loading and unloading operations, eliminating the need for careful manual stacking and tumbling.
2Area of stationary object
If conventional wire mesh shelves are used, then the structure is load-bearing, but the surface area is limited and does not provide stable stacking arrangements for multiple modular racks
Solution Approach 1:
The patent divides the rack system into modular components including multiple shelves, side panels, and stacking mechanisms. Each shelf unit can function independently but is designed to stack with others, increasing total surface area while maintaining stability through standardized connection interfaces between modules.
Solution Approach 2:
The patent implements a nested stacking arrangement where multiple rack units are stacked vertically one within another. The shelves and side panels are configured to fit together in a nested manner, maximizing space utilization while providing stable multi-level stacking arrangements that expand the effective display surface area.
3Adaptability or versatility
If multiple modular racks are stacked to increase display capacity, then more cans can be accommodated, but the stacking arrangement becomes unstable without additional fastening mechanisms
Solution Approach 1:
The patent combines multiple rack units into a unified stacked structure through integrated connection features. The shelves and side panels incorporate built-in stacking interfaces that automatically align and secure adjacent racks, providing stable multi-rack configurations without requiring separate external fastening mechanisms for each connection point.
Solution Approach 2:
The patent designs universal stacking interfaces that serve multiple functions: structural support, alignment guidance, and secure connection. The same shelf and panel components used for displaying cans also provide the stacking and fastening functions, eliminating the need for dedicated complex fastening mechanisms and maintaining configuration flexibility.
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 provides a stable and space-efficient can rack system that facilitates easy loading, presentation, and removal of cans, enhancing visibility and accessibility while accommodating multiple stacked arrangements without requiring extensive tools or fasteners.
Implementation Method 1
The modular racks utilize a coupling effect between convex and concave humps the form along the length of the flat bars to further stabilize the stacked configuration
Implementation Method 2
The modular racks utilize a sloped disposition to enhance viewing the sides of the cans, and also to allow the cans to be gravity fed for dispensing

AI summary
A stackable can rack assembly provides a plurality of modular racks that facilitate both the loading of cans and the presentation of the cans for removal by a consumer. Multiple modular racks can be configured in a variety of stacked arrangement. A plurality of shelves are disposed at a slope to create a gravity fed arrangement to enable the cans to roll forward for dispensing. A pair of side panels support the shelves. The side panels comprise a top flat bar defined by a convex hump having a flat surface, and a bottom flat bar defined by a concave hump having a flat surface. The humps couple together and the flat surface enhance stability for stacking multiple modular racks. At least one bracket affixes to the bottom flat bar to fasten the top and bottom flat bars together. A back panel provide structural integrity to the modular racks.
