Solution Overview

Problem

Traditional air packaging materials provide inadequate cushioning and protection, as they can be damaged easily, leading to a loss of cushioning effect and increased weight and storage space requirements.

Innovation Solution

A crossed staggered and stacked-type air packaging device comprising two or more inflation packaging main body layers arranged in a crossed and staggered manner, with each layer having sub-inflation units extending in different directions, forming a bag-in-bag structure to enhance cushion performance and reliability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional air packaging materials use a single layer structure, then the manufacturing process is simple, but the cushioning performance is inadequate and the structure is easily damaged

Engineering Contradiction:

Improvecushioning performanceVSAvoidlayer structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a nested structure where multiple air packaging layers are stacked one inside another, with each layer containing sub-inflation units. The inner layers are positioned within outer layers, creating a bag-in-bag configuration that provides multiple levels of cushioning protection while maintaining structural integrity even when outer layers are damaged.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

Each air packaging layer is divided into multiple sub-inflation units (first, second, third sub-inflation units) that can be independently inflated. This segmentation allows the packaging system to provide localized cushioning where needed and maintains overall functionality even if individual sub-units are damaged.

Inventive Principle:

Principle #1Segmentation

2Reliability

If air packaging materials are inflated to provide cushioning, then the cushioning effect is improved, but the volume and storage space increase

Engineering Contradiction:

Improvecushioning effectVSAvoidstorage space

Core Design Contradiction:

ReliabilityVSVolume of stationary object

Solution Approach 1:

The air packaging material employs a dynamic structure that transitions from a compact, deflated state for storage and transportation to an inflated, expanded state during use. The multiple layers and sub-inflation units can be selectively inflated based on the packaging requirements, allowing the system to occupy minimal space when not in use while providing ample cushioning when needed.

Inventive Principle:

Principle #15Dynamics

3Reliability

If multiple layers are stacked to improve cushioning, then the protection performance increases, but the weight increases

Engineering Contradiction:

Improveprotection performanceVSAvoidpackaging weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The patent utilizes thin film materials for constructing multiple air packaging layers, where each layer is made from lightweight flexible material that provides sufficient structural integrity for cushioning purposes. The thin film construction minimizes the weight contribution of each layer while maintaining the protective function, allowing multiple layers to be stacked without significant weight penalty.

Inventive Principle:

Principle #30Flexible shells and thin films

4Reliability

If traditional single-layer air packaging is used, then the manufacturing cost is low, but the cushioning performance is insufficient and damage propagation occurs

Engineering Contradiction:

Improvecushioning performanceVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The air packaging structure is designed with universal components that serve multiple functions: the same thin film material and sub-inflation unit design are used across all layers, and the stacking configuration provides both cushioning and structural support functions simultaneously. This multi-functionality reduces the need for specialized components, thereby simplifying the manufacturing process despite the increased layer complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
