Coated Cushioning Sheet With Inserts for Recyclable Shape Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cushioning materials like wrapping paper crumple easily and lose effectiveness under force, while plastic bubble wrap is not recyclable.
Innovation Solution
A cushioning sheet with a base layer and cushioning inserts, where the base layer has voids and is coated to limit air passage, and the inserts are received in these voids to provide cushioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If wrapping paper is used for cushioning, then it can be bunched up and packed around objects to provide cushioning, but it easily crumples under force and loses its volume and effectiveness
Solution Approach 1:
The base layer is divided into multiple cells with voids distributed throughout its structure. This segmentation allows the base layer to maintain its overall shape while providing multiple discrete cushioning zones that can independently deform under pressure, preventing complete collapse and maintaining cushioning effectiveness.
Solution Approach 2:
The invention combines a base layer with voids, cushioning inserts, and an outer layer to create a composite cushioning structure. This composite design integrates the shape-retention properties of the base layer with the cushioning properties of the inserts, solving both the shape retention and cushioning effectiveness requirements simultaneously.
2Strength
If plastic bubble wrap is used for cushioning, then it provides effective cushioning protection, but it is not recyclable
Solution Approach 1:
The invention changes the material parameters from non-recyclable plastic to recyclable paper-based materials. The base layer, cushioning inserts, and outer layer are all constructed from paper or cardstock, maintaining the cushioning function while enabling recyclability and reducing environmental harm.
3Stability of the object's composition
If a base layer with voids and cushioning inserts is used, then shape retention under pressure is improved, but the device complexity increases
Solution Approach 1:
The invention merges the base layer, cushioning inserts, and outer layer into a single integrated cushioning unit. The cushioning inserts are positioned within the voids of the base layer and secured by the outer layer, creating a unified structure that maintains shape while providing cushioning, without requiring separate assembly steps or complex fastening mechanisms.
