Solution Overview

Problem

Existing packaging structures, such as edge protectors and corner boards, face challenges in optimizing the use of paperboard materials to achieve desired configurations while minimizing costs and material usage.

Innovation Solution

A method involving multiple plies of varying widths is used to form a packaging structure, where wider plies are wrapped around narrower plies to create a flat structure that is then bent, allowing for customizable configurations and efficient use of paperboard materials.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple plies of varying widths are used to form a flat paperboard structure, then customization of packaging configurations is improved, but manufacturing complexity increases

Engineering Contradiction:

Improvecustomization of packaging configurationsVSAvoidmanufacturing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The packaging structure is divided into multiple plies of varying widths that are stacked and wrapped together. Each ply can be independently sized and configured, allowing customization of the final packaging dimensions and properties while maintaining a systematic manufacturing approach.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The narrower plies are wrapped around and integrated within the wider plies to form a unified flat paperboard structure. This nesting approach allows multiple components to be combined in a hierarchical manner, achieving complex configurations through systematic assembly rather than intricate single-piece manufacturing.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Loss of substance

If wider plies are wrapped around narrower plies to create a flat structure, then material usage efficiency is improved, but manufacturing process complexity increases

Engineering Contradiction:

Improvematerial usage efficiencyVSAvoidmanufacturing process complexity

Core Design Contradiction:

Loss of substanceVSDevice complexity

Solution Approach 1:

The plies are prepared with predetermined widths and stacked in a specific sequence before wrapping. This preliminary arrangement optimizes material usage by ensuring that each ply is sized appropriately for its position in the final structure, reducing waste while maintaining a systematic manufacturing flow.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The width parameter of each ply is varied systematically based on its position and function in the packaging structure. By changing the width parameter across different plies rather than using uniform dimensions, the design achieves optimal material efficiency while the variation follows a predictable pattern that simplifies manufacturing.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method of manufacturing a packaging structure. The packaging structure includes a first ply having a first end, a second end, and a first width extending between the first and second ends, a plurality of second plies, and a third ply. The method includes adhering the first ply, the one second ply, the other second ply, and the third ply. The method further includes wrapping the one second ply around the first end of the first ply and not the second end of the first ply, wrapping the other second ply around the second end of the first ply and not the first end of the first ply, and wrapping the third ply around the first ply and the plurality of second plies to form a flat paperboard structure of approximately the first width. Moreover, the method includes bending the flat paperboard structure to form the packaging structure.
