Flight Bar Assembly for Staggered Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging methods using cardboard trays and shrink film are resource-intensive, require complex machinery, and lack flexibility in configuring object arrangements, often resulting in inefficient use of space and stability issues due to orthogonal grid arrangements.
Innovation Solution
A flight bar assembly with movable spacers and guides that nest objects in a staggered arrangement, allowing for flexible packaging configurations without the need for trays or cardboard blanks, enabling efficient and stable hexagonal or honeycomb nesting patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If cardboard trays and shrink film are used for packaging, then objects can be grouped and held stably, but more raw materials and resources are required
Solution Approach 1:
The invention extracts and eliminates the cardboard tray and shrink film from the packaging system, retaining only the essential function of holding and stabilizing objects through the flight bar assembly itself, which uses minimal material compared to traditional trays and wrapping films
Solution Approach 2:
The flight bar assembly provides stability through localized contact points and nesting structures rather than requiring complete enclosure with trays and shrink film, applying support only where needed to maintain object stability
2Stability of the object's composition
If cardboard trays with folded edges are used, then objects can be held in place during shipping, but complicated machinery is required to organize and assemble the packages
Solution Approach 1:
The invention removes the need for complex assembly machinery by eliminating the tray-folding and shrink-wrapping processes, using a simplified flight bar assembly that organizes objects through basic pushing and nesting motions
Solution Approach 2:
Instead of using complex machinery to assemble objects into trays and then wrap them, the invention inverts the approach by using simple flight bars to directly nest and organize objects in their final stable configuration without intermediate assembly steps
3Ease of manufacture
If orthogonal grid arrangement is used on trays, then objects can be organized in regular patterns, but interior objects contact only four adjacent objects reducing stability
Solution Approach 1:
The invention transitions from the symmetric orthogonal grid arrangement to an asymmetric staggered nesting pattern where objects in odd rows are offset relative to objects in even rows, allowing interior objects to contact more than four adjacent objects and improving overall package stability
Solution Approach 2:
The flight bar assembly introduces lateral movement and positioning capabilities that enable objects to be arranged in a staggered configuration across multiple dimensions, rather than being constrained to a simple two-dimensional orthogonal grid
4Device complexity
If fixed packaging configurations are used, then machinery can be simplified, but flexibility to change product or grouping is lost requiring major changes
Solution Approach 1:
The flight bar assembly incorporates movable spacers and adjustable components that allow the packaging configuration to be dynamically changed between different product types and grouping patterns without requiring major machinery modifications
Solution Approach 2:
The flight bar assembly is designed as a universal platform that can accommodate various product types, sizes, and grouping configurations through adjustable spacers and nesting patterns, eliminating the need for dedicated machinery for each packaging variant

AI summary
Apparatus, flight bar assemblies, and methods are disclosed for nesting objects into a substantially staggered arrangement. Such nesting may be done in a nesting zone of a machine, for example, just upstream of a shrink wrapping machine. The nested arrangement allows the grouping of nested objects to be shrink-wrapped without use of trays or cardboard blanks if desired. The flight bar assemblies may include movable spacers for orienting rows of objects before, during, and after nesting. Lane dividers may be provided having lengths corresponding to a contour of an outer guide and cam surface, cooperating with the lane dividers to selectively urging the rows of objects inward in an organized fashion to allow efficient and reliable nesting.
