Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cushioning materials for wrapping objects are difficult to handle and require cumbersome methods for sheet separation, often leading to improper handling and the need for additional packaging during transport.
Innovation Solution
A stack of prefabricated sheets of three-dimensional cushioning material connected by a releasable adhesive system, allowing easy sheet removal without tools or heat, and featuring embossed protrusions and perforation lines for adaptability and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If sheets are connected by zigzag fold, then sheets can be stored compactly, but sheet separation becomes difficult and requires two hands
Solution Approach 1:
The patent extracts the connection function from the zigzag fold structure and relocates it to adhesive strips applied only at the edges of sheets. This allows the bulk of the sheet to remain free and easily separable while maintaining connection through the adhesive edges, resolving the contradiction between compact storage and easy separation.
Solution Approach 2:
The connection system is segmented into discrete adhesive strips located at specific edges rather than continuous zigzag folding across the entire sheet. This segmentation allows individual sheets to be separated by lifting from non-adhesive areas while maintaining connection through adhesive edges, simplifying the separation operation.
2Ease of operation
If sheets are stored in a solid box, then sheets are protected during transport, but handling and access become cumbersome
Solution Approach 1:
The adhesive connection is established in advance during manufacturing, allowing sheets to be stored loosely stacked without requiring a protective box. The preliminary adhesive bonding prevents unstacking during transport while maintaining ease of handling, eliminating the need for cumbersome boxed storage.
Solution Approach 2:
The adhesive strips act as an intermediary connection mechanism that provides sufficient stability during transport without requiring rigid confinement. This intermediate solution replaces the need for solid boxes while maintaining protection against inadvertent unstacking.
3Strength
If adhesive system is applied to entire sheet surface, then connection strength is maximized, but sheet separation becomes difficult
Solution Approach 1:
The adhesive system is applied locally only at the edges of sheets rather than across the entire surface. This localized application provides sufficient connection strength to prevent unstacking during transport while leaving the majority of the sheet surface free for easy manual separation by lifting.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy handling and quick access to cushioning sheets, preventing unintended unstacking during transport and allowing for efficient wrapping of objects without damaging them, while providing superior cushioning and adaptability.
Implementation Method 1
adjacent sheets are connected to each other preferably in the region of at least one edge by means of a releasable adhesive system
Implementation Method 2
each sheet has at least portions having a distinctive thickness providing the elasticity which is necessary for providing the required cushioning properties

AI summary
A supply of cushioning material for wrapping at least one object comprises a stack formed of a multitude of prefabricated sheets of three-dimensional cushioning material. The invention proposes that adjacent sheets are connected to each other by means of a releasable adhesive system, the adhesive system being designed such that the connection can be released without auxiliary means, i.e. without special heat exposure and without chemicals and without special tools simply by mechanical action, and non-destructively, i.e. without damaging the cushioning material.
