Cardboard Box Forming with Abutting Flaps for Article Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating boxes from cardboard blanks often result in oversized boxes with empty spaces, leading to unwanted movement of articles due to estimation errors in volume calculation.
Innovation Solution
The method involves folding cardboard blanks with specific score lines and incisions to form abutting flaps that interpose between articles and the box walls, reducing movement by aligning with the articles' dimensions for a snug fit.

Engineering Contradiction Analysis
1Productivity
If estimation-based volume calculation is used to determine cardboard blank dimensions, then boxing process is simplified and faster, but box size accuracy deteriorates leading to empty spaces and article movement
Solution Approach 1:
The patent applies preliminary action by pre-configuring the cardboard blank with score lines and incisions that will automatically form abutting flaps during the boxing process. The blank is designed in advance with geometric features (score lines at specific angles, incisions at calculated positions) that enable self-adjustment to article dimensions, eliminating the need for post-formation adjustments while ensuring precise fit.
Solution Approach 2:
The patent changes geometric parameters of the cardboard blank including score line angles (e.g., 45 degrees), incision depths and positions, and flap dimensions. These parameter variations allow the blank to transform during folding into a box that precisely accommodates articles of different sizes while maintaining structural integrity and minimizing empty spaces.
2Stability of the object's composition
If abutting flaps are formed from cardboard blank, then article stability improves by reducing movement, but manufacturing complexity increases due to additional score lines and incisions
Solution Approach 1:
The patent segments the cardboard blank into multiple functional zones defined by score lines and incisions. The blank is divided into lateral portions, auxiliary portions, and abutting flaps that can be independently folded and positioned. This segmentation allows each element to perform its specific function (lateral containment, reinforcement, article abutting) while maintaining overall structural coherence.
Solution Approach 2:
The patent applies local quality by giving different regions of the cardboard blank different structural properties. Auxiliary portions are positioned specifically at corners and edges where reinforcement is needed, while abutting flaps are located to contact specific surfaces of articles. Each zone is optimized for its local function, providing targeted stability without uniformly increasing overall complexity.

AI summary
Plural articles are arranged in a reusable crate. A cardboard blank is selected in accordance with the volume of the arranged articles. The blank has a first and a second longitudinal score line defining a main portion and a first, a second, a third and a fourth lateral portion, the blank also having a first, a second, a third and a fourth incision that subdivide auxiliary portions into first parts and second parts. The blank and the reusable crate are reciprocally positioned, the bottom of the reusable crate then opened to release the articles onto the blank. The first, second, third and fourth lateral portions are folded towards the articles, with the respective first parts and second parts of the auxiliary portions folding one on another to form respective flaps abutting the group of articles.
