Shock-absorbing Packing Box with Partially Fused Air Cells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shock-absorbing packing materials, such as paper boxes with attached air caps or separate shock-absorbing sheets, face challenges in providing effective impact protection and thermal insulation, especially for articles with irregular shapes and during transportation, due to low shock-absorbing performance and complex manufacturing processes that increase costs.
Innovation Solution
A shock-absorbing packing box is designed with partially fused inner and outer shells to form a box-shaped structure with multiple air cells, enhancing impact resistance and thermal insulation by creating a multi-layered air cell structure, which is more effective in protecting articles with varied shapes and maintaining temperature stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a paper box with attached air caps or separate shock-absorbing sheets is used, then the manufacturing process is simple, but the shock-absorbing performance is low and thermal insulation is insufficient
Solution Approach 1:
The patent combines the shock-absorbing function and thermal insulation function into a single integrated air cell structure. The air cells are formed by sealing air between inner and outer shells, creating a unified structure that simultaneously provides both protection functions, eliminating the need for separate shock-absorbing sheets or attached air caps
Solution Approach 2:
The patent uses a composite structure consisting of inner shells, outer shells, and trapped air to create a multi-functional packing material. The combination of these different elements (solid shells and gaseous air) creates a composite system that delivers both shock-absorbing and thermal insulation properties
2Device complexity
If multiple small air caps are attached to the inner wall of a packing box, then the structure is simple to manufacture, but the shock-absorbing performance is relatively low due to wide non-shock-absorbing spaces between air caps
Solution Approach 1:
The patent divides the packing space into multiple discrete air cells formed between inner and outer shells. Each air cell acts as an independent shock-absorbing unit, and the collective arrangement of these segmented cells provides comprehensive protection without leaving non-shock-absorbing gaps
Solution Approach 2:
The patent transitions from attaching discrete air caps on a two-dimensional surface to creating a three-dimensional network of air cells that fill the entire packing volume. This dimensional expansion eliminates empty spaces and provides continuous shock-absorbing coverage throughout the box
3Ease of operation
If a pocket type shock-absorbing packing material is used, then it is easy to accommodate articles, but it is difficult to pack articles with various shapes such as cylindrical or hexahedral articles
Solution Approach 1:
The patent creates a dynamic packing structure where the inner shells can move and deform independently within the outer shells. This mobility allows the air cell structure to adapt its shape and conform to articles of various geometries, whether cylindrical, hexahedral, or irregular, while maintaining shock-absorbing capability
Solution Approach 2:
The patent uses flexible shell structures that can deform and reshape themselves to accommodate different article forms. The thin film nature of the shells allows them to bend and adapt to various geometries while maintaining the sealed air cells for shock protection
4Stability of the object's composition
If inner shells are completely fused between outer shells to form air cells, then the structure is stable, but the manufacturing process becomes complicated and costs increase
Solution Approach 1:
The patent applies partial fusion rather than complete fusion of inner shells with outer shells. The inner shells are fused at specific locations sufficient to trap and seal the air cells, but not completely fused throughout, which simplifies the manufacturing process while maintaining structural stability and shock-absorbing functionality
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 solution provides a stable box-shaped structure with improved shock-absorbing and thermal insulation performance, effectively protecting articles from impacts and maintaining temperature stability, making it suitable for packing items that need to be kept warm or cold.
Implementation Method 1
shock-absorbing performance is improved, and furthermore, when the shock-absorbing packing material forming the shock-absorbing packing box is formed
Implementation Method 2
the plurality of air cells filled with the air are connected in an overall box-shaped structure, whereby a packing means having a stable structure with a box shape is provided
Implementation Method 3
a heat transfer between the inside and the outside of the packing material through portions where the air cells are connected to each other may be effectively blocked due to the air cells formed in the two-layered structure
