Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing buffer materials formed through pulp molding are prone to deformation under large impact loads, requiring larger sizes to achieve sufficient buffering, which increases material and transport costs.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the buffer material size is increased to achieve sufficient buffering against large impact loads, then the buffering performance is improved, but the material cost and transport cost increase
Solution Approach 1:
The buffer material employs a nested structure where a first buffer portion and a second buffer portion are arranged concentrically. The first buffer portion has a first cylindrical shape extending from the outer circumferential edge, while the second buffer portion has a second cylindrical shape extending from the inner circumferential edge. This nested arrangement allows the buffer material to achieve sufficient buffering performance against large impact loads without increasing the overall material quantity, as the two portions work together to absorb impact energy efficiently.
Solution Approach 2:
The buffer material is divided into multiple functional portions: a first buffer portion and a second buffer portion, each with specific cylindrical shapes and positions. The first buffer portion extends from the outer circumferential edge in a direction opposite to the opening, while the second buffer portion extends from the inner circumferential edge. This segmentation allows each portion to be optimized for specific impact absorption functions, improving overall buffering performance without requiring excessive material quantity.
2Reliability
If the buffer material size is increased to achieve sufficient buffering against large impact loads, then the buffering performance is improved, but the transport cost increases
Solution Approach 1:
The nested arrangement of the first and second buffer portions allows the buffer material to achieve effective buffering performance within a compact footprint. The first buffer portion and second buffer portion are positioned concentrically, maximizing the use of internal space and minimizing the overall volume required for impact absorption, thereby reducing transport costs while maintaining reliability.
Solution Approach 2:
The buffer material utilizes three-dimensional spatial arrangement by extending cylindrical portions in opposite directions from the planar portion's edges. The first cylindrical portion extends from the outer circumferential edge in a direction opposite to the opening, while the second cylindrical portion extends from the inner circumferential edge. This dimensional optimization allows efficient impact absorption without increasing the overall material footprint, reducing transport costs.
3Device complexity
If the buffer material is designed with a single buffer portion, then the structure is simple, but the buffering performance against large impact loads is insufficient
Solution Approach 1:
The buffer material is segmented into a first buffer portion and a second buffer portion, each with distinct cylindrical shapes and positions. The first buffer portion extends from the outer circumferential edge while the second buffer portion extends from the inner circumferential edge. This segmentation enables the structure to maintain simplicity in terms of modular design while significantly improving buffering performance against large impact loads through the coordinated action of multiple portions.
Solution Approach 2:
The nested structure of the first and second buffer portions allows the design to maintain relative simplicity while enhancing buffering performance. The first buffer portion and second buffer portion are arranged concentrically, creating an efficient use of space that improves impact absorption capability without requiring a completely complex multi-component system.
