Packing Sheet with Dynamic Air Columns for Logistics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packing materials, such as air cap wrapping sheets, incur high logistics costs due to large volume during transportation and storage, and suffer from reduced insulation due to heat exchange at welded air cells.
Innovation Solution
A method for producing a packing sheet with improved insulation and storage properties involves forming a film with convex ridges, sealing and opening these ridges, and filling them with gas or liquid, while using check valves to manage fluid injection and minimize volume during transport, and providing a light reflection layer for enhanced insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If air cap wrapping sheet is used to provide cushioning function, then protection against external impacts is improved, but volume during transportation and storage increases significantly
Solution Approach 1:
The packing sheet uses dynamically changeable air columns that can be inflated or deflated. During transportation, the air columns are deflated to minimize volume. When needed for cushioning, air is injected through injection holes to inflate the air columns, providing the required protection against external impacts.
Solution Approach 2:
The invention changes the physical state of the packing material by controlling the inflation and deflation of air columns. By adjusting the air pressure and volume parameters, the packing sheet transitions between a compact state for transportation and an expanded state for cushioning protection.
2Stability of the object's composition
If air cells are welded together to form structure, then shape stability is improved, but heat exchange increases reducing insulation property
Solution Approach 1:
The packing sheet divides the air-filled structure into multiple separate air columns rather than welding them into a continuous structure. Each air column is independently formed within the porous foam material, creating segmented compartments that maintain shape stability while minimizing heat exchange through the welded portions.
