Hammock-Type Air Sheath With Suspended Buffering Sheet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air packing bags used for vibration absorption are prone to puncturing during transportation, leading to air leakage and inadequate buffering protection for packaged articles, especially under greater vibration or impact loads.
Innovation Solution
A hammock-type vibration-absorbing air sheath is designed with heat-sealed edges and nodes allowing for air column formation, a buffering sheet suspended within a receiving space, and a serial check valve system to prevent air leakage, providing dual vibration-absorbing effects while preventing direct contact between the article and the air columns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If an air packing bag is used to provide buffering protection, then the buffering effect is improved, but the reliability deteriorates due to easy puncturing and air leakage
Solution Approach 1:
The air packing bag is divided into multiple air columns by heat-sealed air column lines, creating independent compartments. This segmentation prevents a single puncture from compromising the entire structure, as each air column can be independently sealed or replaced while maintaining overall buffering functionality.
Solution Approach 2:
The invention uses a flexible buffering sheet with heat-sealed edges and nodes that can bend and deform to absorb impact forces. The flexible structure distributes stress across multiple points rather than concentrating it at a single weak point, reducing the likelihood of puncturing while maintaining effective buffering protection.
2Reliability
If the buffering sheet is fully heat-sealed to prevent air leakage, then the reliability is improved, but the vibration-absorbing capability deteriorates due to reduced flexibility
Solution Approach 1:
The buffering sheet is divided into multiple sealed compartments by air column lines, with each segment heat-sealed independently. This segmentation allows each compartment to maintain its own pressure and flexibility while preventing air leakage between compartments, thus preserving vibration-absorbing capability while ensuring reliability.
Solution Approach 2:
The buffering sheet incorporates nodes that allow controlled bending and dynamic deformation. These nodes enable the sheet to adapt its shape in response to vibrations and impacts while maintaining heat-sealed integrity, ensuring both reliability and vibration-absorbing functionality are preserved through dynamic adjustment rather than rigid sealing.

Function Achieved in This Case
The hammock-type vibration-absorbing air sheath effectively absorbs vibrations and protects articles from damage by preventing air leakage, offering enhanced buffering protection against shocks and impacts during transportation.
Implementation Method 1
a first side edge connected to the first buffering wall via the first heat-sealed edge by heat sealing means and a second side edge connected to the second buffering wall via the second heat-sealed edge by heat sealing means
Implementation Method 2
The air packing bag uses air as a buffering medium of an article, so as to provide a buffering effect for protecting the article
Implementation Method 3
the buffering sheet is suspended within the receiving space for receiving the article, in order to absorb a vibration of the article and protect the article with a buffering of the first buffering wall, the second buffering wall, and the third buffering wall

AI summary
A hammock-type vibration-absorbing air sheath includes a first buffering wall (21) having at least one first node (21b), and a second buffering wall (22) having at least one second node (22b). The first buffering wall is bent along the first node, and the second buffering wall is bent along the second node. At least one first heat-sealed edge (21a) of the first buffering wall is connected to at least one second heat-sealed edge (22a) of the second buffering wall by heat sealing means. Thus, a receiving space (6) is formed between the first buffering wall and the second buffering wall, while a buffering sheet (5) is suspended within the receiving space for receiving an article. The buffering sheet is used to absorb vibrations of the article, while the first buffering wall and the second buffering wall are used to protect the article.
