Solution Overview

Problem

Containers often require improved packaging materials to effectively protect items during shipping, as existing solutions fail to provide adequate protection and customization for various product sizes and shapes.

Innovation Solution

A corrugated fiberboard blank is designed with a singlewall board and a hingedly coupled singleface board section, allowing for flexible configuration and customization to form containers with specific dimensions and shapes, enhancing protection and usability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional plastic or foam-based packaging materials are used, then protection during shipping is provided, but environmental sustainability and customization for various product sizes and shapes are insufficient

Engineering Contradiction:

Improveprotection during shippingVSAvoidcustomization for various product sizes and shapes

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The packaging is divided into multiple sections: a first section formed from a singlewall board that creates the main container structure, and a second section formed from a singleface board that can be received within the first section. This segmentation allows each section to be optimized for different functions while maintaining overall protection and enabling customization for various product sizes and shapes.

Inventive Principle:

Principle #1Segmentation

2Strength

If a singlewall board is used to form the container, then structural strength is provided, but flexibility in configuration and customization is limited

Engineering Contradiction:

Improvestructural strengthVSAvoidflexibility in configuration

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The invention combines a singlewall board section (提供 structural strength) with a singleface board section (提供 flexibility). The second section comprising a singleface board can be received within the first section, merging the advantages of both board types to achieve both structural integrity and configurational flexibility.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If packaging materials are added to protect items, then protection is improved, but device complexity and manufacturing complexity increase

Engineering Contradiction:

Improveprotection of itemsVSAvoidpackaging structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The second section comprising a singleface board is designed to be received within the first section, creating a nested structure. This nesting approach provides enhanced protection through multiple layers while maintaining relatively simple manufacturing processes and avoiding excessive structural complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A corrugated fiberboard blank has a first section that forms a container and a second section that is receivable within the formed container. The first section can be singlewall board and the second section can be singleface board that is hingedly coupled to the first section such that the second section can be received within the first section when the first section forms the container.
