Solution Overview

Problem

Conventional corrugated fiberboard containers lack sufficient structural integrity and stacking strength, particularly when used for delivery and display purposes.

Innovation Solution

The development of corrugated fiberboard containers with a reinforcing portion that includes spaced-apart front wall reinforcement portions secured to the exterior portion, featuring removable panels that overlap for easy access and enhanced structural support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional corrugated fiberboard containers are used, then manufacturing is simple, but structural integrity and stacking strength are insufficient

Engineering Contradiction:

Improvestructural integrityVSAvoidcontainer structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The container is divided into an exterior portion and a separate reinforcing portion, allowing the reinforcement to be added as a distinct module rather than requiring complete redesign of the entire container structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The container combines the exterior corrugated fiberboard with an internal reinforcing portion made of similar material, creating a composite structure that leverages the strengths of both layers to achieve superior structural integrity

Inventive Principle:

Principle #40Composite materials

2Strength

If conventional corrugated fiberboard containers are used, then manufacturing is simple, but stacking strength is insufficient

Engineering Contradiction:

Improvestacking strengthVSAvoidcontainer structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The reinforcing portion is segmented into spaced-apart front wall reinforcement portions, allowing strategic reinforcement at critical load-bearing areas without requiring complete structural redesign

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The dual-layer construction with exterior and reinforcing portions creates a composite structure that significantly enhances stacking strength by distributing loads across multiple layers and attachment points

Inventive Principle:

Principle #40Composite materials

3Ease of operation

If removable panels are added for display access, then ease of operation improves, but structural integrity may be compromised

Engineering Contradiction:

Improvedisplay accessVSAvoidstructural integrity

Core Design Contradiction:

Ease of operationVSStrength

Solution Approach 1:

The front wall is segmented into removable panels and fixed portions, allowing selective removal for display access while maintaining the structural integrity of the remaining attached sections

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The removable panels are pre-configured with attachment mechanisms that maintain structural support when closed, and are designed to be removed only when display access is needed, preserving strength during storage and transport

Inventive Principle:

Principle #10Preliminary action

AI summary

A blank for use in forming a container, such as a corrugated fiberboard container, can include a reinforcement portion that provide improved structural integrity for a display ready container. The reinforcing portion can include at least a first front wall reinforcement portion and a second front wall reinforcement portion, with the first and second front wall reinforcement portions being spaced apart from one another. The front wall and a front top section can have removable panels when used as a display container.
