Folded Tray with Partition Walls for Non-Flat Product Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper or cardboard trays for transporting and displaying foodstuff products lack stability during handling and transport, especially when containing non-flat bottomed items, and require complex assembly processes.
Innovation Solution
A tray design featuring a single folded sheet with perpendicular side walls and separating walls that create compartments, providing support and stability through connecting points and gluing points, allowing for easy assembly and stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a folded sheet container with reduced height side walls is used, then the structure is simple and low-cost, but the stability during handling and transport deteriorates
Solution Approach 1:
The tray is divided into multiple compartments by partition walls, with each compartment independently supporting products. This segmentation provides stable support for non-flat bottomed items while maintaining the overall simple folded sheet structure
Solution Approach 2:
The partition walls extend vertically to a height greater than the side walls, creating a three-dimensional support structure that prevents product displacement during transport, adding vertical dimensionality to the support function
2Stability of the object's composition
If connecting portions are provided between separating walls and side walls, then stability is improved, but the assembly process becomes more complex
Solution Approach 1:
The connecting portions are integrated directly into the folded sheet structure during manufacturing, merging the connection function with the structural elements. This allows stable connections between partition walls and side walls while maintaining simple assembly from a single pre-formed sheet
3Reliability
If separating walls extend beyond side walls in vertical direction, then product support is improved, but the manufacturing complexity increases
Solution Approach 1:
The partition walls are pre-formed to extend beyond the side walls in the folded sheet structure before products are placed. This preliminary configuration ensures immediate product support capability while avoiding complex post-assembly manufacturing steps

AI summary
A tray is described for transporting and displaying foodstuff products, comprising a sheet that is folded so as to define: - a bottom (2); - a first pair of side walls (4, 6) oriented along a first direction (Y); and - a second pair of side walls (8, 12) oriented along a second direction (X) transversal to said first direction (Y), said tray being characterized in that said folded sheet, furthermore, defines: two separating walls (14, 16) that extend along said first direction (Y), and are parallel to one another and are spaced apart from each other so as to divide the tray in distinct compartments (C); wherein said separating walls (14, 16) extend along said first direction (Y) so far as to place respective opposite edges immediately next to said second pair of side walls (8, 12), wherein said separating walls (14, 16) and/or said second pair of side walls (8, 12) have connecting portions (132) that connect said opposite edges of said separating walls (14, 16) to said second pair of side walls (8, 12).
