Food Can Stacking Insert for Non-Necked Can Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-necked-in food cans, including three-piece cans and other types, cannot be efficiently or safely stacked due to uniform outer dimensions, leading to potential instability and space inefficiency during storage.
Innovation Solution
A custom-designed food can stacking device with a unique geometry that fits inside the inner diameter of the lower can's top rim and accommodates variations in can shape, allowing the upper can to fit over it, ensuring stable stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If non-necked-in food cans with uniform outer dimensions are used, then manufacturing simplicity is maintained, but stacking stability and space efficiency deteriorate
Solution Approach 1:
The patent introduces an intermediary stacking device with a tapered geometry that mediates between two uniform-diameter cans. This device fits within the inner diameter of the lower can's top rim and provides a surface with greater diameter than the upper can's outer diameter, enabling stable stacking without requiring the cans themselves to be modified with necked-in portions.
2Ease of manufacture
If non-necked-in food cans with uniform outer dimensions are used, then manufacturing simplicity is maintained, but storage space utilization deteriorates
Solution Approach 1:
The stacking device enables compact vertical arrangement of uniform-diameter cans by providing a stable interface between cans. This intermediary component allows the cans to be stacked in a space-efficient manner similar to necked-in cans, optimizing storage space utilization without requiring changes to the can manufacturing process.
3Device complexity
If non-necked-in food cans are stacked directly, then device complexity is minimized, but reliability and safety deteriorate due to potential falling
Solution Approach 1:
The patent introduces a simple intermediary stacking device with tapered geometry that fits within the lower can's top rim and supports the upper can. This device provides mechanical interlocking and stability, preventing the upper can from falling off during vibration or movement, thereby significantly improving stacking reliability without adding complex mechanisms.
