Stratodesign Packaging Method for Cost-Effective 3D Envelopment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging design methods are inefficient in addressing cost and time constraints, particularly for high-value products, as they often require expensive tools and do not allow for direct and automatic production from digital product definitions.
Innovation Solution
The integration of digital design into the product digitization process using stratoconception, where a virtual counter-shape of the product is defined to generate geometric data for each layer, enabling 3D machining and cutting of layers that can be stacked to form a custom-fit packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional packaging design methods are used, then packaging can be produced, but expensive tools are required and production time increases
Solution Approach 1:
The patent uses digital copying of the product geometry to generate the packaging design. The counter-shape is created as a digital copy of the product's 3D model, allowing automatic generation of packaging patterns without physical prototypes or expensive tooling. This digital copying approach eliminates the need for traditional physical patterning tools while maintaining design accuracy.
Solution Approach 2:
The patent performs preliminary digital design and validation of the packaging before actual production. The counter-shape and layer patterns are fully defined in the digital domain prior to manufacturing, allowing all geometric calculations and optimizations to be completed beforehand. This preliminary digital action prevents rework during production and reduces both cost and time.
2Reliability
If traditional 2D outline projection methods are used for packaging design, then packaging can be created, but the protection and transport security are insufficient
Solution Approach 1:
The patent transitions from 2D outline projection to 3D counter-shape modeling. By creating a three-dimensional counter-shape that mirrors the product's geometry, the system achieves superior envelopment and protection. This dimensional upgrade allows the packaging to conform to the product's complex 3D form rather than relying on simplified 2D projections.
Solution Approach 2:
The patent divides the 3D counter-shape into multiple stackable layers with defined cutting patterns. This segmentation allows complex 3D geometry to be manufactured from simpler 2D plate materials that are cut and stacked to form the complete packaging. The segmentation maintains the protective benefits of 3D design while enabling practical manufacturing from flat materials.
3Productivity
If expensive tools and non-recyclable materials are used for packaging production, then packaging can be manufactured efficiently, but environmental sustainability is compromised
Solution Approach 1:
The patent changes the material parameter from non-recyclable materials to recyclable plate materials. By maintaining the efficient digital design and cutting process while substituting the material type, the system achieves both high productivity and environmental sustainability. The parameter change in material selection does not compromise manufacturing efficiency because the digital patterning and cutting processes are material-agnostic.
