Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If one-size-fits-all packaging is used, then device complexity is reduced, but product protection is insufficient and shipping costs increase
Solution Approach 1:
The packaging system transitions from static pre-designed boxes to dynamic custom-fit packaging generated through 3D scanning and additive manufacturing. The system adapts to each item's specific dimensions and shape requirements, providing optimal protection while maintaining operational simplicity through automated scanning and printing processes.
Solution Approach 2:
The packaging parameters (size, shape, material density) are dynamically adjusted based on the scanned item characteristics. The additive manufacturing process varies material deposition parameters to create packaging with optimal protection properties for each specific item, resolving the contradiction between simplicity and effectiveness.
2Reliability
If custom packaging is designed for each item, then product protection is improved, but manufacturing cost increases
Solution Approach 1:
The system uses biodegradable starch-based materials for additive manufacturing, creating disposable packaging that is inexpensive to produce. The materials are naturally decomposable, eliminating the need for expensive durable packaging solutions while maintaining adequate protection for single-use shipping scenarios.
Solution Approach 2:
The additive manufacturing process optimizes material usage by precisely depositing starch-based material only where needed, reducing waste compared to traditional cutting and assembly methods. The variable layer thickness and material density parameters allow cost-effective production tailored to each item's protection requirements.
3Ease of manufacture
If standard sized packages are used, then manufacturing simplicity is maintained, but shipping space is wasted and costs increase
Solution Approach 1:
The packaging size and shape are dynamically determined through 3D scanning of the item, eliminating the need for oversized standard boxes. The additive manufacturing process then creates packaging that precisely fits the item's dimensions, maximizing shipping space utilization without complicating the manufacturing workflow.
Solution Approach 2:
The system integrates multiple functions into a single workflow: 3D scanning for measurement, automated design generation, and additive manufacturing for production. This universal system handles diverse item shapes and sizes through one process, achieving custom-fit efficiency without sacrificing manufacturing simplicity.
4Reliability
If excessive packing materials are used, then product protection is improved, but material waste increases and shipping cost increases
Solution Approach 1:
The additive manufacturing process applies starch-based material with varying density and thickness at different locations based on the item's specific protection needs. Critical areas receive more material while less vulnerable areas receive minimal coverage, eliminating the need for uniform excessive packaging and reducing overall material waste.
Solution Approach 2:
The system dynamically adjusts material deposition parameters including layer thickness, infill density, and material composition based on real-time analysis of the item's geometry and vulnerability. This precise parameter control ensures adequate protection while minimizing material usage, directly addressing the contradiction between protection and waste.

AI summary
A system and process of printing a package of expanded material (e.g., expanded starch, foam or other expanded material). The expanded material can be heated and extruded, poured, sprayed, or otherwise applied in malleable form that sets up to become a porous protective covering for an item to be packaged. In an example, a layer of expanded material is laid down, and the item in a protective covering (e.g., a plastic bag, sleeve, coating, etc.) is positioned on the layer of expanded material. Additional layers or expanded material may be applied, thereby encasing the item. The top surface of the expanded material may be flattened, such as by operation of a roller, press, or cutter. The top surface may be sprayed with a shellac sealant, paint, or other coating, to allow printing of a label on the top surface.
