Honeycomb Paper Pad Shape Fixing to Prevent Elastic Springback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing honeycomb cell shock-protection paper pads revert to their original shape due to elasticity after stretching and extending, causing operational difficulties and inefficiencies.
Innovation Solution
A honeycomb cell shock-protection paper pad structure with uniformly distributed and spaced paper strips, featuring folded-edge and central bends, is formed through stretching, edge-collapsing, and rolling processes to fix the shape and prevent restoration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the honeycomb cell shock-protection paper pad is stretched and extended to provide shock absorption, then the shock protection effect is improved, but the paper pad restores back to its original shape due to elasticity, causing operational difficulties
Solution Approach 1:
The paper strips are pre-formed with folded-edge bend portions at their ends and central bend portions at connected sites before the stretching process. These pre-formed bends act as shape-fixing features that prevent the paper pad from restoring to its original shape after stretching, thereby maintaining operational stability while preserving shock absorption capability
Solution Approach 2:
The invention introduces localized structural features (folded-edge bends and central bends) at specific locations of the paper strips rather than uniformly modifying the entire structure. The folded-edge bend portions are located at unconnected sites while central bend portions are at connected sites, creating local structural differences that collectively prevent shape restoration
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 structure maintains a fixed shape, enhancing shock absorption and simplifying operation with a non-deformable, easy-to-use design.
Implementation Method 1
The paper-made cellular-form shock-protection pad is generally elastic, and after the paper-made cellular-form shock-protection pad has been stretched and extended, the paper-made cellular-form shock-protection pad so stretched and extended may restore back to the original shape by means of the elasticity
