Enantiomorphic Packaging Compartments for Stable Automated Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging solutions with irregular tetrahedron compartments face challenges in automated stacking due to differing speeds and order requirements for identical and enantiomorphic compartments, leading to instability in stacking configurations.
Innovation Solution
The packaging design features two enantiomorphic compartments that can rotate into configurations forming either a square-based or isosceles triangular pyramid, allowing for compact stacking and self-stabilization by pairing enantiomorphs, facilitating unitary stacking ratios and automation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If identical and enantiomorphic compartments are stacked individually, then the packing volume is filled, but the stacking process requires different speeds and orders for different compartment types, complicating automation
Solution Approach 1:
The patent combines an identical compartment and an enantiomorphic compartment into a single packaging unit with a common base. This merging allows both compartment types to be stacked together in a unified manner, eliminating the need for separate stacking processes with different speeds and orders, thereby simplifying automation while maintaining complete packing volume utilization
2Stability of the object's composition
If compartments are stacked in a fixed order, then the packing structure is formed, but the stacking configuration becomes unstable
Solution Approach 1:
The patent utilizes the enantiomorphic (mirror-image) asymmetry of the two compartment types around a common base. This asymmetric design allows the compartments to interlock in a stable configuration where the combined center of gravity is lowered and the structure self-stabilizes, enabling stable stacking without requiring complex ordering constraints that would reduce productivity
3Volume of stationary object
If six compartments are stacked to form a cube, then the packing volume is optimized, but the stacking requires precise ordering of identical and enantiomorphic compartments
Solution Approach 1:
By merging identical and enantiomorphic compartments into unified packages with common bases, the patent enables these combined units to be stacked directly into cubic or parallelepiped configurations. This approach maintains optimal packing volume efficiency while simplifying the stacking operation, as the combined packages can be stacked in any order without requiring differentiation between compartment types

AI summary
The invention relates to a method for manufacturing a packaging according to a manufacturing cycle, during which two casings (38) are made from two packaging strips (31) and the formation of a closing edge (AB, CD - EF, GH) along each housing (38) alternates with the filling of the casing with a material to be packaged, such as to customize, in the casing, a filled and closed compartment (10, 20), the formation of the closing edge (AB, CD - EF, GH) being controlled at an angle to a feed direction (T) for each casing. According to the invention, the packaging strip (31) has a longitudinal direction (U) controlled at an angle (β) to the feed direction (T) and supported by a means (28, 32, 62) for feeding each casing (38), and the manufacturing cycle includes: an operation of dividing up the closing edges (AB, CD - EF, GH) such as to separate a left compartment (10), made from the casing from the strip (31) having a predetermined strip length (a√2) and being wound in a counterclockwise rotational direction (S), and a right compartment (20), made from the casing from the strip (31) having a predetermined strip length (a√2) and being wound in a clockwise rotational direction (D); and an operation of assembling both the left and right compartments via a connection joining two edges (AB, EF) that each extend between tops that correspond with one another, in the two enantiomorphic compartments (10, 20), in relation to a mirror plane containing the connection, relative to which both compartments pivot, in a configuration where said compartments form a pyramid having a square base (AEHGCD), or in a configuration where said compartments form a pyramid having an isosceles triangle base.
