Solution Overview

Problem

Existing technologies for preventing load collapse in stacked objects on pallets and trucks are inadequate in effectively securing corners and maintaining structural integrity during transportation.

Innovation Solution

A corner protector with two rectangular surface portions, a bent portion, a notch, and a folding line, allowing for various deformation modes to securely engage with corners of loaded objects, thereby preventing load collapse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing load collapse prevention technologies are used, then some protection is provided, but the corners are not securely engaged and structural integrity is not maintained

Engineering Contradiction:

Improvecorner engagement reliabilityVSAvoidstructural integrity

Core Design Contradiction:

ReliabilityVSStrength

Solution Approach 1:

The corner protector is divided into multiple functional segments: two surface portions for engagement, a bent portion for corner fitting, a notch for adjustment, and a folding line for deformation. This segmentation allows each part to perform its specific function optimally, enabling secure corner engagement while maintaining overall structural integrity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The corner protector incorporates a folding line that allows the structure to dynamically deform and adapt to different corner configurations. This dynamic capability enables the protector to securely engage with corners while maintaining structural integrity under varying loading conditions.

Inventive Principle:

Principle #15Dynamics

2Strength

If a rigid corner protector structure is used, then structural integrity is maintained, but adaptability to different loading configurations is reduced

Engineering Contradiction:

Improvestructural integrityVSAvoidloading configuration adaptability

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The folding line creates a hinge that allows the corner protector to dynamically adjust its shape and orientation. This enables the same structure to adapt to various loading configurations while maintaining structural integrity through its engineered fold geometry.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The corner protector allows for parameter changes in its geometric configuration through the folding line, enabling adaptation to different corner angles and loading scenarios while preserving the fundamental structural integrity of the design.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If a simple corner protector design is used, then manufacturing is easier, but the ability to securely engage corners and prevent load collapse is insufficient

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidcorner engagement reliability

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

By segmenting the corner protector into distinct functional elements (surface portions, bent portion, notch, folding line), the design achieves complex corner engagement capabilities while maintaining relative manufacturing simplicity through standardized forming processes.

Inventive Principle:

Principle #1Segmentation

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.
