Bakery Tray With Collapsible Handles And Tapered Ribs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bakery trays lack efficient design features for compact storage and structural integrity, particularly in handling and stacking, which can lead to damage during transportation and storage.
Innovation Solution
A bakery tray design featuring collapsible handles with a locking mechanism, structural ribs, and channels for enhanced stability and ease of stacking, along with a diamond pattern of support ribs that taper for reduced material usage and improved manufacturing quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If handles are made pivotable to reduce tray height for compact storage, then storage efficiency is improved, but structural stability deteriorates
Solution Approach 1:
The handle is designed to be pivotable between an extended position for handling and a retracted position for compact storage. The dynamic mechanism allows the handle to move between fixed positions while maintaining structural integrity through a locking groove that secures the handle in its extended position during use.
2Ease of manufacture
If support ribs are made with uniform width for simplicity, then manufacturing ease is improved, but structural strength deteriorates
Solution Approach 1:
The support ribs have varying widths along their length, with wider sections at intersections with the peripheral wall and narrower sections between intersections. This local variation in rib width provides enhanced structural strength at critical junction points while reducing material usage in less critical areas.
3Manufacturing precision
If support ribs maintain nominal width throughout for consistency, then manufacturing precision is improved, but material efficiency deteriorates
Solution Approach 1:
The support ribs feature a tapered cross-section where the width varies along the length of the rib. The ribs are widest at their intersections with the peripheral wall where maximum strength is needed, and progressively narrower toward their midsections, optimizing material distribution according to structural requirements.
4Strength
If handles are made fixed for structural integrity, then strength is improved, but adaptability deteriorates
Solution Approach 1:
The handle is designed as a movable component that can pivot between an extended handling position and a retracted storage position. The dynamic design includes a pivot point at the front edge of the base and a locking groove that secures the handle in its extended position, providing both adaptability and structural integrity when needed.

AI summary
A molded bakery tray include a tray body that has a top surface, a bottom surface, and a peripheral wall around a perimeter of the tray body. Support ribs on the bottom surface intersect an inner surface of the peripheral wall at intersection points along at least one side of the tray body. The support ribs taper from a nominal width to an intersection width at the intersection points, the intersection width being less than the nominal width.
