Coupled Shock Absorber Structure for Even Packaging Deformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock absorbers for packaging materials do not evenly distribute impact absorption, leading to uneven deformation and potential damage to packaged objects due to integration of shock-absorbing ribs with the base structure, which affects the ability to achieve targeted impact reduction.
Innovation Solution
A shock absorber system comprising a frame-shaped first shock absorber with internal ribs and a plate-shaped second shock absorber, where the two components are coupled separately to allow even deformation and improved impact absorption, using materials like form resin, pulp molding, or vacuum-formed plastic sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If shock-absorbing ribs are integrated with the base structure, then the shock absorber can be manufactured as a single piece, but the impact absorption becomes uneven and deformation is concentrated in specific areas
Solution Approach 1:
The shock absorber is divided into a base structure and separate shock-absorbing ribs that are coupled together. This segmentation allows each component to be optimized independently - the base structure provides structural support while the separate ribs can deform uniformly to distribute impact forces evenly across the contact surface with the packaged object.
2Object-affected harmful factors
If the shock-absorbing rib height and contact area are adjusted, then the impact acceleration can be reduced, but the deformation becomes uneven and may damage the packaged object
Solution Approach 1:
The shock-absorbing ribs are designed with specific local geometric features including rounded tips and optimized cross-sectional shapes. These local quality adjustments ensure that when the ribs deform under impact, the deformation is distributed uniformly across all ribs rather than concentrating in specific areas, thereby protecting the packaged object from localized stress concentrations.
3Productivity
If a single shock absorber design is used, then the packaging process is simplified, but the shock absorption cannot be optimized for different impact scenarios
Solution Approach 1:
The coupled structure of base structure and shock-absorbing ribs creates a multi-functional shock absorber that can adapt to different impact scenarios. The ribs can be designed with various heights, thicknesses, and arrangements to address different impact levels and directions, while still using the same basic coupled structure. This universality allows one shock absorber design to serve multiple protection functions.
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 ensures even distribution of impact absorption, reducing the risk of damage to packaged items by allowing independent deformation of the internal ribs, enhancing shock-absorbing effects and compatibility with packaging processes.
Implementation Method 1
The height h of the shock-absorbing rib 12 and the shaded area S in which the object to be packaged contacts the shock-absorbing rib 12 can be adjusted to lighten the acceleration of the impact that is applied to the object to be packaged at the time of falling or drop
Implementation Method 2
a desired function of shock absorbers is to lessen the impact of the shock on the object to be packaged when the packaged baggage drops or falls off during cargo handling

AI summary
A shock absorber and two packaging systems. The shock absorber is to be attached to an object to be packaged, and the shock absorber includes a first shock absorber including a first base structure having a frame shape and at least one first shock-absorbing rib disposed inside the first base structure, and a second shock absorber having a second base structure in a shape of a plate and at least one second shock-absorbing rib disposed on a plane of the second base structure. In the shock absorber, the first shock absorber and the second shock absorber are coupled to each other. One of the two packaging systems includes shock absorbers including the shock absorber, and two of the shock absorbers are used for each object to be packaged. In the other one of the two packaging systems, four of the shock absorbers are used for each object to be packaged.
