Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corrugated fiberboard packaging materials require multiple layers to achieve sufficient strength, resulting in increased thickness and costs, and are limited to rectangular shapes, leading to inefficiencies in shipping and storage.
Innovation Solution
A packaging material composed of a plurality of triangular cells formed from a single or multiple sheets of corrugated fiberboard, which can be converted into a cylindrical shape, providing enhanced strength with reduced thickness and allowing for flexible packaging configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple layers of corrugated fiberboard are laminated together to form doubled-walled or triple-walled shipping boxes, then the strength of the packaging material is improved, but the thickness and cost increase
Solution Approach 1:
The packaging material is divided into a plurality of triangular cells formed from individual corrugated fiberboard layers. Each triangular cell acts as an independent structural unit that contributes to the overall strength while maintaining a single-layer configuration, eliminating the need for multiple laminated layers.
Solution Approach 2:
The invention transitions from a traditional flat, planar packaging structure to a three-dimensional cylindrical shape formed by triangular cells. This dimensional change allows the single-layer material to achieve the structural integrity normally requiring multiple layers, as the triangular geometry provides inherent structural strength.
2Strength
If multiple layers of corrugated fiberboard are laminated together to form doubled-walled or triple-walled shipping boxes, then the strength of the packaging material is improved, but the cost increases
Solution Approach 1:
The packaging is segmented into triangular cells that maximize structural efficiency. This segmentation allows a single layer of corrugated fiberboard to provide sufficient strength through geometric configuration rather than material quantity, reducing the total material usage compared to multi-layer constructions.
Solution Approach 2:
The invention changes the structural parameters from traditional flat panels to triangular cellular geometry. This parameter change transforms how strength is achieved - through shape and configuration rather than through increasing material quantity or layer count - thereby reducing overall material consumption and cost.
3Ease of manufacture
If traditional corrugated fiberboard packaging is used, then the manufacturing process is simple, but the packaging is limited to rectangular shapes reducing shipping and storage efficiency
Solution Approach 1:
The packaging material is designed with collapsible triangular cells that allow the structure to transition between expanded and collapsed states. This dynamic capability enables the packaging to adapt to different shipping configurations and storage requirements while maintaining ease of manufacture through the modular cellular structure.
Solution Approach 2:
The invention adopts a cylindrical shape formed by triangular cells rather than traditional rectangular forms. This curved, cylindrical configuration optimizes space utilization in shipping containers and storage facilities while the modular triangular cell structure maintains manufacturing simplicity through standardized construction processes.
