Inflation Bag Protective Base Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging materials for large-sized or thin-shaped objects during transportation often fail to provide sufficient shock absorption and cushioning, leading to damage from external forces, particularly at corners and edges.
Innovation Solution
An inflation bag with a protective base formed by stacking and heat-sealing two outer and two inner films, featuring a structured bottom with multiple columns and heat-seal nodes to create cushioning spaces, along with side surface walls and optional cushioning or limiting gas bags for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional packaging materials are used for large-sized or thin-shaped objects, then the packaging can be simple in structure, but the shock absorption and cushioning function are insufficient
Solution Approach 1:
The bottom surface wall is divided into multiple bottom columns, each with protection column portions that are folded to form protective bases. This segmentation allows the packaging to provide localized shock absorption at critical areas (corners and edges) while maintaining overall structural simplicity.
Solution Approach 2:
The protection column portions are folded along fold lines to transform from a flat two-dimensional structure to a three-dimensional protective base structure. This dimensional change creates cushioning spaces that provide shock absorption functionality without significantly increasing the flat packaging area.
2Strength
If multiple protective structures are added to enhance shock absorption, then the cushioning function is improved, but the manufacturing complexity increases
Solution Approach 1:
The protective base structure is merged with the bottom surface wall of the packaging bag, forming an integrated structure. The protection column portions are part of the same film structure as the bottom surface wall, connected through fold lines and heat-seal nodes. This merging eliminates the need for separate protective components and reduces manufacturing steps.
Solution Approach 2:
The packaging structure itself provides the protective function through its own structural features (bottom columns with protection column portions that form protective bases). The packaging serves dual purposes: containing the object and providing shock absorption, eliminating the need for additional dedicated protective components.
3Strength
If the bottom surface wall is made stronger to provide protection, then the shockproof function is improved, but the flexibility and ease of inflation may be reduced
Solution Approach 1:
The bottom columns are designed to be folded along fold lines, creating a dynamic structure that can transition from a flat state during inflation to a three-dimensional protective base structure after inflation. This dynamic design allows the bottom surface to provide strength when needed while maintaining flexibility during the inflation process.
Solution Approach 2:
The protective base is formed from the same flexible film material as the rest of the packaging bag, using fold lines and heat-seal nodes to create the protective structure. This approach maintains the flexibility and inflatability characteristics of thin-film packaging while providing enhanced bottom surface strength through the three-dimensional protective base structure.

AI summary
An inflation bag with protective base is provided. Two outer films and two inner films are stacked with each other, and the stacked structure is heat sealed and inflated to form the inflation bag. The inflation bag includes two side surface walls and a bottom surface wall between the side surface walls and connected to bottoms of the side surface walls. The bottom surface wall includes bottom columns. Each bottom column has a first bottom column portion, a protection column portion, and a second column portion. A first heat-seal node is provided for attaching the outer films with the inner films, and the first bottom column portion is connected to the second bottom column portion. One or more second heat-seal nodes are provided on the protection column portion for attaching the outer films with the inner films, and the protection column portions are folded to form a protective base.
