Corrugated Cardboard Transport Device for Pattern Stacks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing logistics chain for transporting packaging patterns from manufacturers to customers is inefficient, leading to potential crushing of stacks, increased packaging material usage, and waste generation during transportation.
Innovation Solution
A transport device made from folded sheet material, such as corrugated cardboard, with uprights and lateral extensions that provide rigidity, reduces packaging needs, minimizes weight, and facilitates easy handling and stacking, featuring a top panel with a gripping cutout and reversible locking mechanisms for secure closure and easy opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional box-type packaging is used to transport stacks of patterns, then the stacks are protected from crushing, but the quantity of packaging material increases and weight increases
Solution Approach 1:
The packaging structure is merged with the transport function by forming the box directly from the sheet material blank that contains the patterns. The uprights are erected from the same material as the patterns, combining the packaging container and the transported goods into a single integrated structure, eliminating the need for separate outer packaging boxes.
Solution Approach 2:
The sheet material blank serves multiple functions simultaneously: it contains the patterns for transport, forms the protective box structure through erected uprights, and provides the base and top panel for complete enclosure. This multi-functional design replaces the need for separate packaging materials.

The uprights are erected from the same material as the patterns, combining the packaging container and the transported goods into a single integrated structure, eliminating the need for separate outer packaging boxes.

3Strength
If lateral extensions are added to the uprights, then the rigidity of the device increases and crushing risks are reduced, but the device complexity increases
Solution Approach 1:
The lateral extensions are integrated directly into the uprights as continuous folded portions of the same sheet material, rather than being separate components. This merging of the extension feature with the upright structure provides reinforcement without adding assembly complexity or requiring additional parts.
Solution Approach 2:
The uprights are segmented into functional zones: the main vertical portion for structural support and the laterally folded extension portions for rigidity reinforcement. This segmentation allows each zone to perform its specific function while maintaining a unified one-piece construction from the sheet material blank.

AI summary
The device (100) has two posts (104) for retaining a stack (200) of patterns (201) from bottom to a top panel. Each post is provided in the form of a band of a material that is drawn up from the bottom to the top panel for joining the post. Each post is connected to the bottom and the top panel by a folding line (110b) and bordered beyond a side that is formed by another folding line (116) by a side extension (117), which is folded toward an outer side of the device and extended from the bottom to the top panel. The device has a blank (101) whose sheet material formed as a paperboard or corrugated cardboard from a semi-rigid plastic. Independent claims are also included for the following: (1) a case-pallet (2) a blank (3) a method for feeding a sheet feeder in patterns.
