Adjustable Airtight Sheath for Variable-Size Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packing materials, such as foam and inflatable air packs, fail to provide uniform protection and are not adjustable to fit various sizes of electronic products, leading to increased costs and inconvenience due to the need for multiple sizes of packing materials.
Innovation Solution
An airtight sheath made of heat-sealed outer films with adjustable air columns and a foldable unit that can be inflated to form a three-dimensional buffering structure, allowing for adjustment of the packing space to fit different object sizes by folding or using narrowing sealing lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional air packs are used for packing, then the packing materials can provide some buffering protection, but they are not adjustable in size to fit different widths or lengths of electrical products
Solution Approach 1:
The air pack incorporates a foldable unit with a bending body that can be bent from the buffering unit, allowing the packing space to be dynamically adjusted. The foldable unit includes abutting air columns that can be positioned to narrow or expand the packing space according to the size of the electrical product being packed
Solution Approach 2:
The air pack is divided into distinct buffering units and a foldable unit with multiple air columns. This segmentation allows different portions of the air pack to be independently adjusted or folded to accommodate various product dimensions while maintaining a single versatile packing solution
2Ease of operation
If conventional air packs are used for packing, then the packing process can be simplified, but they fail to protect electrical products during loading due to their sheet-like shape
Solution Approach 1:
The foldable unit with the bending body can be dynamically adjusted to wrap around electrical products during loading, providing reliable protection. The abutting air columns can be positioned to conform to the product shape, ensuring protection while maintaining ease of operation
Solution Approach 2:
The air pack uses a flexible structure with multiple air columns that can be inflated to provide cushioning protection. The foldable unit with the bending body acts as a flexible shell that can adapt to different product shapes, providing reliable protection during loading and delivery
3Volume of stationary object
If multiple air packs are arranged in a carton, then they can fill the space more integrally, but they remain scattered and do not provide uniform protection
Solution Approach 1:
The air pack is segmented into multiple buffering units with air columns arranged in specific patterns. This segmentation allows the single air pack to fill the carton space integrally while maintaining uniform protection through the distributed air column structure
Solution Approach 2:
Multiple buffering units with air columns are merged into a single integrated air pack structure. This combining approach fills the carton space uniformly while providing consistent protection, eliminating the scattered arrangement of multiple separate air packs

AI summary
An airtight sheath includes a first buffering unit, a second buffering unit, a bottom buffering unit, and a foldable unit. Two terminating sides are formed at opposite sides of the second buffering unit to be heat-sealed to two opposite sides of the first buffering body. A packing space is formed and surrounded by the first, second, and bottom buffering units. The foldable unit includes a bending body, and a plurality of abutting air columns. The bending body is bendable from the second buffering unit so that the foldable unit is foldable into the packing space, where the packing space is capable of being narrowed by the abutting air columns and the first buffering unit. The airtight sheath is capable of fittingly packing an object having a small size as the foldable unit is folded, or an object having a larger size as the foldable unit is unfolded.
