Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The packaging industry in China lacks innovative packaging patent technologies, leading to a passive and low-value market. Additionally, eco-friendly materials struggle to replace plastic due to insufficient elasticity, and there is a need for cost-effective, simple, and environmentally friendly packaging solutions that comply with plastic bans and carbon emission reduction goals.
Innovation Solution
A buffer product for packaging is developed using eco-friendly materials such as PLA, paper, bamboo, and straw. The product consists of a base material layer with hollow tubes arranged in parallel on its surface, providing elasticity and cushioning. An inspection and material selection method is also introduced to ensure the buffer product can withstand various loads and impacts during transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If plastic foam materials (EPS, EPE, PU) are used for packaging, then elasticity and cushioning performance are improved, but environmental friendliness deteriorates
Solution Approach 1:
The patent changes the material parameter from conventional plastic foam to molded pulp material, transforming the packaging material from non-degradable to biodegradable while maintaining protective functions. This resolves the contradiction by selecting an alternative material that provides both environmental benefits and adequate cushioning performance.
Solution Approach 2:
The patent uses composite structure combining molded pulp material with specific geometric shapes (hollow spherical, cubic, or cylindrical structures) to achieve both environmental friendliness and elasticity. The composite design of material + structure compensates for the lower inherent elasticity of pulp compared to plastic foam.
2Object-affected harmful factors
If molded pulp material is used instead of plastic, then environmental friendliness is improved, but elasticity and cushioning performance deteriorate
Solution Approach 1:
The patent employs hollow spherical, cubic, or cylindrical geometric shapes for the molded pulp packaging units. These curved and three-dimensional structures provide better shock absorption and elasticity compared to flat or simple rectangular forms, thereby improving cushioning performance while maintaining environmental friendliness.
Solution Approach 2:
The patent creates localized cushioning zones through the hollow internal structure and specific geometric configurations. The hollow spaces and curved surfaces concentrate elastic properties at critical impact points, providing enhanced protection in areas most susceptible to damage while using minimal material throughout.
3Adaptability or versatility
If complex packaging designs are used, then innovation and functionality are improved, but cost and material waste increase
Solution Approach 1:
The patent divides the packaging system into standardized modular units with uniform geometric shapes. These segmented, interchangeable modules can be combined in various configurations to protect different product sizes and shapes, providing design versatility while using simple, efficient moldings that minimize material waste.
Solution Approach 2:
The patent designs universal molded pulp units that can serve multiple packaging functions (cushioning, structural support, void filling) and accommodate various product types. This multi-functionality reduces the need for specialized complex designs for each application, thereby reducing overall material consumption and simplifying production.
