Tension-Applying Cushioning System for Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cushioning materials that deform to conform to packaged objects have a poor ability to restore to their original state and maintain pressing force, especially when made of paper, making it difficult to effectively protect the objects during transportation.
Innovation Solution
A cushioning system within a packaging box that includes a bottom plate, a top plate with a cushioning portion, and folding portions that apply tension to the cushioning portion, allowing it to conform to the object's shape and maintain holding force through slits and support structures like support legs and arms, which increase the tension and holding force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cushioning is formed by deforming a box part to conform to the object shape, then the cushioning can wrap and hold the object, but the cushioning has poor ability to restore to original state and maintain pressing force
Solution Approach 1:
The cushioning is divided into multiple functional portions: a body portion with discontinuous slits for conforming to the object shape, and separate standing portions that can be pushed in to apply pressing force. This segmentation allows each portion to perform its specific function independently, resolving the contradiction between adaptability and reliability.
Solution Approach 2:
The cushioning incorporates movable standing portions that can be pushed in to dynamically adjust and maintain pressing force on the object. This dynamic mechanism ensures the cushioning can adapt to different object shapes while maintaining reliable pressing force through the movable components.
2Ease of manufacture
If paper is used as cushioning material, then the cushioning can be lightweight and easy to manufacture, but the tendency to have poor restoration ability is more obvious
Solution Approach 1:
The paper cushioning is segmented into a body portion and separate standing portions, allowing the paper to be easily manufactured while the standing portions provide the necessary structural support for reliable pressing force maintenance.
Solution Approach 2:
The paper material forms flexible thin-walled structures with slits that can deform to conform to object shapes while maintaining enough structural integrity through the standing portions to provide reliable cushioning force.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively maintains a consistent pressing force on the object, reducing movement and impact, and can accommodate various shapes and sizes by deforming to fit the object's shape, enhancing protection during transportation.
Implementation Method 1
the cushioning portion is deformed so as to conform to the outer shape of the object and covers the object

AI summary
Cushioning constituting a part of a box configured to accommodate an object to be packaged includes: a bottom plate on which the object to be packaged is to be placed; a top plate including a cushioning portion having a cushioning function, the cushioning portion and the bottom plate being configured to hold the object to be packaged therebetween; and a folding portion to be folded from the top plate over the bottom plate to apply tension to the cushioning portion holding the object to be packaged.
