Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging materials for transporting objects are inflexible, expensive, and lack adaptability to the object's outer shape, offering inadequate protection against bumps and knocks.
Innovation Solution
A packaging material featuring a nonwoven layer of thermoplastic plastic fibers with spaced, parallel elongated depressions, which allows for easy bending around corners and edges, combined with a protective plastic or metal film for enhanced shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual strips are laminated on both sides with film or paper, then the packaging material is flexible, but the outer shape of the item being packaged is not very adaptable and offers little protection against impacts and shocks
Solution Approach 1:
The packaging material is divided into multiple longitudinal strips that are spaced apart, allowing each strip to independently conform to the contours of the packaged item. This segmentation enables both adaptability to shape and impact absorption, as the strips can move independently to cushion shocks while wrapping around corners and edges.
Solution Approach 2:
The packaging material utilizes a nonwoven fabric structure with inherent porosity and compressibility. This porous structure allows the material to deform and conform to irregular item shapes while the compressed air pockets within the porous structure provide cushioning against impacts and shocks.
2Ease of operation
If the packaging material is made flexible with spaced strips, then it can wrap around corners, but the material is expensive to manufacture and not very stable
Solution Approach 1:
The invention changes the physical parameters of the packaging material by using a nonwoven fabric with specific compressibility and thermal properties. This allows the material to be easily formed into the desired strip configuration through heat treatment, simplifying manufacturing while maintaining flexibility for wrapping around corners.
Solution Approach 2:
The packaging material uses inexpensive nonwoven fabric that can be easily manufactured and disposed of after single use. This approach reduces manufacturing costs compared to reusable rigid structures, while the material's stability is sufficient for its intended single-use packaging application.
3Object-affected harmful factors
If the packaging material provides robust protection against impacts, then it offers good shock absorption, but it may reduce flexibility and adaptability
Solution Approach 1:
The packaging material exhibits dynamic properties, transitioning from a flexible state during application to a more rigid state during impact. The nonwoven fabric strips can easily bend and conform during wrapping, but compressibility increases under impact forces, providing shock absorption while maintaining adaptability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The material effectively adapts to the object's contours, providing robust protection against impacts and being both stable and cost-effective to manufacture, while also being rollable and foldable.
Implementation Method 1
the heat used for producing the elongated depressions be generated by high frequency or ultrafrequency or by hot stamping rollers, so that partial stiffening in the area of the depressions is achieved
Implementation Method 2
the soft, fluid layers between the indentations protect the item from impacts and shocks during transport and assembly
