Foldable Corner Protector Structure for Stable Stacked Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corner protectors fail to effectively prevent load collapse and maintain stability during transportation of stacked loads, particularly when subjected to weight compression.
Innovation Solution
A foldable corner protector with notches and folding lines that allows deformation to fit snugly around corners, providing support and stability by being abutted on the corners of loaded objects, and utilizing packaging film to secure the protector in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid corner protector structure is used, then it provides strong protection against load collapse, but it cannot adapt to different corner shapes and sizes
Solution Approach 1:
The corner protector is divided into multiple surface portions (first surface portion, second surface portion, third surface portion, fourth surface portion) connected by folding lines. This segmentation allows each portion to be independently positioned and folded to match different corner geometries, providing adaptability while maintaining overall structural strength for load protection.
Solution Approach 2:
The corner protector transitions from a static rigid structure to a dynamic foldable structure. The folding lines enable the protector to change its configuration adaptively during application, allowing it to conform to various corner shapes and sizes while maintaining sufficient rigidity when deployed to prevent load collapse.
2Adaptability or versatility
If a foldable corner protector with multiple surface portions is used, then it can adapt to different corner shapes, but the structure becomes more complex
Solution Approach 1:
The corner protector consists of four surface portions connected by folding lines, creating a modular structure that adapts to different corners. This segmentation provides adaptability without excessive complexity, as each portion serves a specific function and can be independently positioned during application.
3Adaptability or versatility
If the corner protector is designed to be deformed by folding, then it can fit snugly around corners, but the manufacturing precision requirements increase
Solution Approach 1:
The folding lines are pre-formed during manufacturing at specific locations on the corner protector. This preliminary action ensures that when the protector is applied to corners, the folding can occur at the correct positions to achieve proper fit, reducing the need for high precision during the actual application process.

AI summary
A corner protector includes two surface portions having a rectangular shape and interposing a bent portion extending parallel to one side; a notch reaching the bent portion from one side of at least one surface portion of the two surface portions; and a folding line reaching one side of the other surface portion from a terminal end of the notch.
