Universal Cardboard Blank for Flat Articles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for packing flat, polygonal objects like tiles are costly, inflexible, and require multiple dedicated stores due to the need for custom-made blanks, which increases production and sales costs.
Innovation Solution
A blank for packing flat, polygonal objects made from identical sheets of corrugated cardboard, with fold lines and connecting flaps that can be assembled to fit different dimensions, using a machine that prepares and folds the material efficiently, reducing the need for specialized stores and production steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If custom-made blanks are used for each article format, then packing precision is improved, but manufacturing cost increases and versatility decreases
Solution Approach 1:
The patent applies universality by designing a single standardized blank format that can be used for multiple different article types and sizes. The blank includes adjustable components such as lateral sectors that can be positioned at different locations along the central sector, allowing the same blank to accommodate various article dimensions without requiring custom-made blanks for each format.
Solution Approach 2:
The patent applies segmentation by dividing the blank into distinct functional sectors: a central sector for receiving articles, lateral sectors for covering flanks, and adjustable positioning elements. This segmentation allows independent adjustment of each sector to fit different article configurations while maintaining a standardized overall blank structure.
2Manufacturing precision
If custom-made blanks are prepared for each article type, then packing precision is improved, but the number of manufacturing operations increases
Solution Approach 1:
The standardized blank design eliminates the need for separate custom-making processes for each article type. A single blank format with adjustable elements serves multiple packing needs, reducing the number of different blank designs that must be manufactured and stored.
Solution Approach 2:
The blank is pre-configured with standardized fold lines, creased lines, and positioning features during manufacturing. These preliminary actions enable quick adjustment and assembly for different article types without requiring complex custom operations at the point of use.
3Manufacturing precision
If multiple dedicated stores are maintained for different blank formats, then packing precision is improved, but storage cost increases
Solution Approach 1:
The patent reduces storage requirements by implementing a universal blank format that can serve multiple article types. Instead of maintaining separate inventory stores for each custom blank format, a single standardized blank design with adjustable elements can be stored and reused for various packing needs.
Solution Approach 2:
The standardized blank design allows for easier recovery and reuse of packing materials. The modular structure with adjustable sectors enables the same blank to be reconfigured for different article types, extending its useful life and reducing the frequency of replacement.

AI summary
The invention relates to a blank (1), a method and a machine (11) for realising the blank (1). The blank (1) is constituted by four lengths (5) which are consecutively joined to form a structure (2) or frame (6) which can be folded around one or more flat articles (4) or tiles to be packed. The machine (11) and the method for realising the blanks (1) include supplying identical panels of cardboard which are joined to constitute a continuous strip (10) and which are subsequently cut to correspond to lengths of sides of the tiles. Each length (5) is joined to a consecutive length (5) by deposits (7a) of glue.
