Protrusion Buffer Packaging for Shock Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging technologies fail to adequately protect products during transportation due to insufficient shock absorption and flexibility, leading to potential damage.
Innovation Solution
A buffer packing material with a substrate board featuring protrusions, such as half-sphere or cone-shaped projections, integrated into a package box design that allows for easy folding and secure closure, providing enhanced protection through internal and external projections that support and buffer accommodated objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional rigid packaging materials are used, then structural strength is improved, but shock absorption capability deteriorates
Solution Approach 1:
The substrate board is designed with an array of projections (convex portions) that create a porous-like structure. These projections deform under impact forces, absorbing shock energy while maintaining the overall structural integrity of the packaging. This resolves the contradiction by providing both strength and shock absorption capability.
Solution Approach 2:
The packaging structure transitions from a flat rigid board to a three-dimensional structure with projections having specific geometric parameters (height, diameter, spacing). These parameter changes enable the material to exhibit both structural strength and shock absorption properties through controlled deformation of the projections.
2Reliability
If complex packaging structures are used, then protection capability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The substrate board is segmented into multiple projections arranged in an array pattern. Each projection acts as an independent shock-absorbing element, allowing the complex protection function to be achieved through simple, repetitive geometric features that are easy to manufacture using standard molding or cutting techniques.
Solution Approach 2:
The projections are designed with curved surfaces (spheroidal or conical shapes) rather than sharp edges. This curvature simplifies the molding process while providing effective shock absorption through gradual deformation. The curved geometry naturally distributes stress and is easier to manufacture than complex angular structures.
3Adaptability or versatility
If packaging materials with high flexibility are used, then adaptability is improved, but structural strength deteriorates
Solution Approach 1:
The packaging structure incorporates dynamic elements through the projections that can deform elastically under load. The projections bend and compress to absorb impacts, then return to their original shape, providing both flexibility for adaptation to different packaging needs and sufficient structural strength when required.

AI summary
A package box includes a substrate board and a plurality of projections. The projections are formed on the substrate board. The substrate board includes a first surface and a second surface. The first surface is opposite to the second surface. Each of the projections is formed when the first surface of the substrate board protrudes toward the second surface of the substrate board.
