Packaging Plate for Honeycomb Body Impact Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging materials for honeycomb structured bodies, used in filtering exhaust gases, fail to adequately protect these components from external impacts during transportation, leading to potential damage such as cracks.
Innovation Solution
A packaging material comprising a plate member with an installation portion and a reinforcing portion, featuring grooves or concave portions, and surface irregularities, which sandwiches the honeycomb structured body to prevent bending and damage during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple plate member is used for packaging, then the device complexity is reduced, but the strength and protection against external impact deteriorates
Solution Approach 1:
The packaging plate has different structural characteristics at different locations: the installation portion has a specific shape (truncated cone or bottomed hole) to accommodate the honeycomb body, while the reinforcing portion has grooves or concave structures to enhance strength. This local differentiation allows the simple plate structure to provide both ease of installation and adequate protection.
Solution Approach 2:
The packaging plate is functionally segmented into two distinct portions: an installation portion for positioning the honeycomb body and a reinforcing portion for providing structural strength. The reinforcing portion includes multiple grooves or concave portions that segment the load-bearing structure, distributing impact forces more effectively.
2Ease of operation
If the installation portion has a large contact area, then the ease of operation is improved, but the strength deteriorates due to increased susceptibility to impact damage
Solution Approach 1:
The installation portion has a specifically designed shape (truncated cone or bottomed hole) that provides adequate contact area for easy installation while avoiding excessive contact that would increase impact susceptibility. The tapered or bottomed design ensures proper positioning without creating a large flat surface vulnerable to impact.
3Strength
If the plate member is made thicker to increase strength, then the strength is improved, but the weight increases
Solution Approach 1:
Instead of uniformly increasing plate thickness, the reinforcing portion is segmented into multiple grooves or concave portions. This segmentation creates a truss-like structure that provides high strength-to-weight ratio by distributing loads through the groove network without requiring excessive material thickness.
Solution Approach 2:
The packaging plate uses composite structural elements combining the base plate material with groove/convex reinforcement features. This composite approach allows the plate to achieve enhanced strength without proportionally increasing weight, as the grooves create structural efficiency rather than simply adding material.
