Vibration-absorbing air sheath end-closing structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration-absorbing air sheaths with irregular, towering corners in the binding portion are prone to air column bursting under pressure, leading to loss of vibration-absorbing function and unbalanced load distribution due to wavy edges and shrinkage at the accommodating space openings.
Innovation Solution
The air columns of the first and second buffering walls have different diameters and inclined upper ends, with outward slanted creases formed at the lower parts to eliminate corners and maximize the accommodating space width, ensuring a flat plane for improved buffering and preventing wavy edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the buffering walls are formed with regular heat-seal edges, then the manufacturing process is simple, but the corners become irregular and towering which are prone to air column bursting under pressure
Solution Approach 1:
The buffering wall is divided into multiple air columns separated by heat-seal edges. Each air column is an independent structural unit that can deform and absorb energy independently, preventing the propagation of stress concentrations that would lead to catastrophic failure of the entire structure.
Solution Approach 2:
The patent intentionally creates asymmetric air column configurations with different diameters adjacent to each other. This asymmetry prevents the formation of regular towering corners while maintaining structural integrity, as the varying column sizes distribute stress more evenly and eliminate the geometric discontinuities that cause failure points.
2Ease of manufacture
If the air columns have uniform diameters, then the manufacturing process is simpler, but the accommodating space width cannot be maximized and load distribution becomes unbalanced
Solution Approach 1:
The patent employs asymmetric air column design where adjacent air columns have different diameters. This asymmetry allows the structure to maximize the accommodating space width by creating a more efficient space-filling pattern, while the varied column sizes naturally balance the load distribution across the buffering wall structure.
Solution Approach 2:
Different regions of the buffering wall are designed with air columns of different diameters according to the local buffering requirements. Areas requiring greater compression resistance have larger diameter columns, while areas needing more flexibility have smaller columns, optimizing both space utilization and load distribution.
3Device complexity
If the air column lines have vertical upper ends, then the structure is simpler, but wavy edges form at the opening which obstruct larger objects and cause unbalanced loading
Solution Approach 1:
The patent replaces the vertical, angular upper ends of air columns with inclined, curved transitions. This curvature eliminates the formation of wavy edges at the opening, creating a smooth, flat surface that facilitates the placement of larger objects while distributing loads more evenly across the structure.

AI summary
A vibration-absorbing air sheath (100) having improved end-closing structure includes a first (1) and a second (2) buffering wall, at least one first and at least one second node, a third buffering wall (5) and an accommodating space (6). The buffering walls are constructed by air columns (11). The first and second buffering walls (1, 2) are atop heat-sealed together at each of two ends of the air sheath (100) so as to form a binding portion and a lower flat-bottomed opening. After inflation of the air columns (11), the air columns (11) of the first and second buffering walls (1, 2) outside the binding portion and the air columns (51) of the third buffering wall (5) form a triangular end buffering portion. The air columns (11) in the end buffering portion have slanted creases for their easy upward-bending so as to make the air columns (11) in the end buffering portion spread and provide a buffering area at the end of the air sheath's ends.
