Pyramid Box Casing from Pre-Scored Cardboard Blank
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging methods for products like pastries are either time-consuming and difficult to achieve, such as assembled pyramid packages, or expensive, like traditional pastry boxes, especially for small items.
Innovation Solution
A pyramidal envelope box made from a lightweight cardboard blank with scored and folded segments that can be easily assembled into a functional and aesthetically pleasing shape, allowing for quick and automatic folding without requiring extensive skill or experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If an assembled pyramid package is used, then the packaging is compact and presentable, but it requires great skill to fold and takes up to a minute to assemble
Solution Approach 1:
The blank is pre-cut and pre-scored with all necessary fold lines and cut edges prepared in advance. This preliminary preparation allows the packaging to be assembled quickly by simply folding along the pre-marked lines, eliminating the need for complex folding operations during assembly.
Solution Approach 2:
The blank is divided into specific geometric segments with precise fold lines and cut edges. Each segment is designed to fold into a specific position, creating the pyramid shape through systematic folding of pre-defined sections rather than complex manual manipulation.
2Ease of operation
If a traditional pastry box is used, then the packaging is simple to use, but it is expensive due to the cost of the box and decorative ribbon
Solution Approach 1:
The blank serves multiple functions: it provides the structural box, the decorative surface, and the closing mechanism all in one piece. The flaps are integrated into the blank itself, eliminating the need for separate decorative ribbons or additional closing components, thereby reducing material costs while maintaining ease of use.
Solution Approach 2:
The decorative flaps and closing mechanism are merged into the main blank structure. The flaps serve both as decorative elements and as functional closing components, combining what would traditionally be separate elements (box, decoration, and closure) into a single integrated piece.
3Area of stationary object
If a smaller box is used for small supports, then the packaging size is appropriate, but it is disproportionately expensive and even more difficult to assemble correctly
Solution Approach 1:
The blank is pre-cut and pre-scored with all necessary fold lines and cut edges prepared in advance. This preliminary preparation allows the packaging to be assembled quickly by simply folding along the pre-marked lines, eliminating the need for complex folding operations during assembly even for small sizes.
Solution Approach 2:
The design allows for scaling the blank dimensions to match the support size while maintaining the same geometric relationships and fold patterns. By changing the scale parameter of the blank rather than the fundamental design, small boxes can be produced that are both cost-effective and easy to assemble using the same principles as larger versions.

AI summary
A box casing for products, in particular cakes, produced with a cut and grooved cardboard blank (100). It has a location (3) subdivided into quadrants (Qi) by axes (X1, X2, Y1, Y2) intersecting at the point (O). Each quadrant forms a face (F1), bordered by a flap (R1) connected by a bending line (LC1) and an edge (BD1) and a base line (LR) connected to a wing (R1) by a bellows (S1). The folding involves first folding the portions bordering the sides (A1, A4) and (A2, A3) in order to bring together the plates (P1, P2) and the edges (L1, L3), then pressing against the wing (R1) or (R2) in such a way as to automatically fold the other portions of the blank, the corners of which are cut off. The fold lines are grooved lines. The bending line (LC1-LC4) is not grooved.
