Integrally Molded Hinge Packaging Cushion for Impact Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging cushion materials fail to effectively suppress impacts transmitted to articles when housed in a box body, as impacts applied to the box body can easily propagate to the article through the cushion material.
Innovation Solution
A packaging cushion material is designed with a holder portion, a holder support portion, and a hinge portion that are integrally molded as one component. The hinge portion allows the holder portion to be displaceable when folded, thereby absorbing and dissipating impacts applied to the box body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the article is held firmly by the packaging cushion material to prevent displacement, then the article stability is improved, but the impact transmission to the article increases
Solution Approach 1:
The packaging cushion material employs a dynamic structure where the holder portion can displace relative to the holder support portion through the hinge portion. This dynamic capability allows the system to absorb impacts while maintaining article stability, resolving the contradiction between firm holding and impact protection.
Solution Approach 2:
The hinge portion is designed in advance as a cushioning element that can deform and absorb impact energy before it reaches the article. This prior cushioning mechanism protects the article from impacts while maintaining the holder's structural integrity and stability.
2Strength
If the packaging cushion material uses a rigid structure to maintain shape, then the structural strength is improved, but the impact absorption capability deteriorates
Solution Approach 1:
The packaging cushion material is segmented into distinct functional portions: the holder portion for article containment, the holder support portion for structural support, and the hinge portion for impact absorption. This segmentation allows each component to optimize its specific function while maintaining overall structural strength.
Solution Approach 2:
The hinge portion utilizes parameter changes in the material's mechanical properties under compression to absorb impact energy. When impacted, the hinge portion deforms and changes its structural parameters, converting kinetic energy into deformation energy, thereby absorbing impacts while maintaining the rigid structure of the holder and support portions.
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 packaging cushion material effectively suppresses impacts transmitted to the article by allowing the holder portion to displace and absorb vibrations, thereby reducing the risk of damage to the article.
Implementation Method 1
a hinge portion connecting the holder portion and the holder support portion to each other, wherein the holder portion, the holder support portion, and the hinge portion are integrally molded as one component, and when the packaging cushion material is housed in the box body in a state where the hinge portion is folded, the holder support portion supports the holder portion with the hinge portion interposed therebetween such that the holder portion is displaceable

AI summary
A packaging cushion material, to be housed in a box body together with an article, includes a holder portion adapted to accommodate the article, a holder support portion adapted to support the holder portion, and a hinge portion connecting the holder portion and the holder support portion to each other. The holder portion, the holder support portion, and the hinge portion are integrally molded as one component. When the packaging cushion material is housed in the box body in a state where the hinge portion is folded, the holder support portion supports the holder portion with the hinge portion interposed therebetween such that the holder portion is displaceable.
