Packaging Side Lug Stiffening Rib Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging made from foldable materials, such as cardboard, faces challenges in automatically forming stiffening ribs during erection, which can lead to additional work steps, increased storage space requirements, and potential damage during transport or storage.
Innovation Solution
The packaging is designed with a lever mechanism that automatically forms a stiffening rib by pivoting adjacent side walls, where the inner layer sections are initially not in their final position but are aligned to form a triangle when the packaging is erected, eliminating the need for separate work steps and ensuring stability without gluing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If stiffening ribs are formed before packaging erection, then packaging stability is improved, but storage space increases and damage risk during transport increases
Solution Approach 1:
The stiffening rib transitions from a flat, compact state during storage to an erected, stable state during use. The rib is designed to be dynamically transformable, allowing it to occupy minimal space in the flat delivery state and automatically form the stabilizing triangular structure when the packaging is erected, thus resolving the contradiction between storage efficiency and stability.
Solution Approach 2:
The stiffening rib is nested within the side wall structure in a compact form during storage. The rib is integrated into the side wall blank such that it lies flat against the side wall surface, allowing the packaging to be stored in a compact, space-efficient manner while maintaining the capability to form the stabilizing structure when needed.
2Stability of the object's composition
If stiffening ribs are formed before packaging erection, then packaging stability is improved, but risk of damage during transport increases
Solution Approach 1:
The stiffening rib maintains a flexible, flat configuration during transport that can withstand compression and handling forces, then automatically transforms into a rigid, triangular structure when erected. This dynamic transformation allows the rib to absorb transport stresses in its flat state while providing structural stability in its erected state, thereby reducing damage risk.
Solution Approach 2:
The stiffening rib is pre-positioned within the side wall structure in a protected, flat state that prevents damage during storage and transport. The rib is integrated into the side wall blank such that it is shielded by the side wall material itself, and only assumes its load-bearing form when the packaging is erected and the rib is pulled into its triangular configuration.
3Stability of the object's composition
If stiffening ribs are formed by separate work step during erection, then packaging stability is improved, but manufacturing complexity and time increase
Solution Approach 1:
The formation of the stiffening rib is merged with the side wall erection process. The rib is integrated into the side wall blank such that its triangular structure forms automatically as the side wall is erected, eliminating the need for separate rib formation operations. This combining of operations reduces manufacturing complexity and time while ensuring proper rib formation for stability.
Solution Approach 2:
The side wall erection process automatically forms the stiffening rib without requiring separate intervention. As the side wall is pulled into its vertical position, the integrated rib structure is automatically pulled into its triangular configuration, forming itself through the mechanical action of erection. This self-forming mechanism eliminates additional work steps and reduces manufacturing complexity.
4Stability of the object's composition
If stiffening ribs are formed by separate work step during erection, then packaging stability is improved, but erection time increases
Solution Approach 1:
The stiffening rib formation is combined with the side wall erection operation into a single integrated process. As the side wall is erected, the rib automatically forms its triangular structure through the same mechanical motion, eliminating the need for sequential operations. This merging of operations reduces erection time while ensuring proper rib formation for packaging stability.
Solution Approach 2:
The stiffening rib forms itself automatically during the side wall erection process without requiring separate intervention or additional time. The mechanical action of erecting the side wall simultaneously pulls the integrated rib into its triangular configuration, making the rib formation a byproduct of the erection operation rather than a separate step, thus reducing total erection time.

AI summary
The package has a base lug (2), and a side lug (5) that is made from inner and outer layers of foldable material. Reinforcing ribs (8a, 8b) are provided in the side lug, where the package is erected from a delivery condition in which sections forming the side lug are arranged parallel to each other to a usage condition in which the sections of the side lug are aligned perpendicular to each other. The inner and outer layers of the material are formed in such a manner that sections of the inner layer are erected during the erection of the package. Independent claims are also included for the following: (1) a method for manufacturing a package (2) a blank made from foldable material for manufacturing a package.
