Air Cushioning Material Multi-Surface Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cushioning materials for protecting articles during transportation are prone to shifting or falling due to vibrations, as they only contact two surfaces of the article and can easily detach when taped to the article.
Innovation Solution
An air cushioning material comprising multiple air cells and belt-like parts, where the belt-like parts are designed to connect air cells in a specific configuration to ensure the material remains attached to the article even if one tape is peeled off, allowing it to maintain contact with three surfaces and prevent displacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an air cushioning material uses only two air cells connected by a belt-like part, then the structure is simple, but the material easily detaches from the article during transportation
Solution Approach 1:
The patent combines multiple air cells (first, second, third, and fourth air cells) into a single integrated cushioning material structure. These air cells are connected through belt-like parts and coupling parts to form a unified structure that contacts three surfaces of the article, preventing detachment during transportation while maintaining structural simplicity.
2Device complexity
If the air cushioning material contacts only two surfaces of the article, then the material structure is simple, but the material shifts or falls during transportation
Solution Approach 1:
The patent transitions from a two-surface contact configuration to a three-surface contact configuration by adding the coupling part that connects air cells across different faces of the article. This dimensional change from 2D to 3D contact ensures the cushioning material remains stable and does not shift or fall during transportation.
3Reliability
If multiple tapes are used to secure the air cushioning material, then the attachment reliability improves, but the packing process becomes complex
Solution Approach 1:
The cushioning material is segmented into multiple functional parts (first module with first and second air cells, second module with third and fourth air cells, belt-like parts, and coupling parts). This segmentation allows each part to serve a specific function in maintaining contact with different surfaces, achieving high attachment reliability through the structure itself rather than requiring multiple tapes.

AI summary
An air cushioning material includes: a first module including a first air cell containing air, a second air cell containing air, and a first belt-like part connecting the first air cell and the second air cell to each other; a second module including a third air cell containing air, a fourth air cell containing air, and a second belt-like part connecting the third air cell and the fourth air cell to each other; a coupling part that couples a part of the second air cell and a part of the fourth air cell in a second direction, where a direction from the second air cell toward the first air cell and a direction from the fourth air cell toward the third air cell are defined as a first direction, and a direction intersecting the first direction is defined as the second direction.
