Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current packaging materials are not recyclable, bulky, and require additional non-recyclable materials for protection, leading to increased environmental impact and shipping costs.
Innovation Solution
A laminated packaging material with expandable layers that can be shipped in a contracted condition and expanded on-site to form a customized enclosure, providing structural strength without additional fillers, and is fully recyclable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If traditional cardboard packaging is used, then recyclability is improved, but protective ability deteriorates when folded
Solution Approach 1:
The patent uses a multi-layer composite structure combining creped paper layers with air pockets. The creped paper provides structural integrity and recyclability, while the air pockets provide cushioning and protective ability. This composite approach allows the packaging to maintain both environmental friendliness and protective performance.
Solution Approach 2:
The patent incorporates air pockets within the packaging structure, creating a porous material system. These air pockets provide shock absorption and protective cushioning while adding minimal weight. The porous structure allows the packaging to be protective without requiring dense, non-recyclable materials.
2Strength
If preformed cardboard boxes are used, then structural strength is improved, but adaptability to different item sizes deteriorates
Solution Approach 1:
The patent employs a dynamic packaging system where the creped paper layers can be expanded or compressed to match the size and shape of the item being packaged. This dynamic adaptability allows a single packaging type to serve multiple item sizes and shapes while maintaining structural strength through the creped paper's inherent properties.
Solution Approach 2:
The packaging material's physical parameters (such as layer expansion, air pocket volume) can be adjusted to match different item dimensions. This parameter flexibility enables the same packaging base material to adapt to various product sizes while maintaining protective structural strength.
3Reliability
If additional protective materials are added, then protective ability is improved, but material consumption increases
Solution Approach 1:
The patent merges the structural packaging function and the protective cushioning function into a single integrated material system. The creped paper layers and air pockets work together simultaneously to provide both structural support and protective cushioning, eliminating the need for separate protective materials and reducing overall material consumption.
Solution Approach 2:
The creped paper-based packaging material performs multiple functions simultaneously: it provides structural strength, protective cushioning, and recyclability. This multi-functionality eliminates the need for additional specialized protective materials, reducing total material consumption while maintaining adequate protection.

AI summary
In an embodiment, a package enclosure can include a first creped paper packaging material and a second creped paper packaging material. The first creped paper packaging material can include a first single-layer creped packaging paper. The second creped paper packaging material can include a second single-layer creped packaging paper. The first creped paper packaging material and the second creped paper packaging material can define a respective material perimeter, with the second creped paper packaging material being attached to the first creped paper packaging material proximal their respective material perimeters to form a set of bound borders. The first creped paper packaging material and the second creped paper packaging material can thereby be attached together in a manner to define a package enclosure. The materials used for the package enclosure may be referred to as a package material combination.
