Solution Overview

Problem

Existing cartons lack efficient mechanisms for displaying and adjusting the orientation of articles while ensuring secure packaging and minimal material usage.

Innovation Solution

A carton design featuring a tubular structure with a display window and adjustable orientation, incorporating non-linear hinged connections and strategically placed openings to allow for the display and adjustment of articles, while preventing the main body of the article from being removed, and utilizing a complementary locking mechanism for secure assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If a display window is provided in the carton, then the article can be displayed for viewing, but the structural integrity and strength of the carton may be compromised

Engineering Contradiction:

Improvearticle visibilityVSAvoidcarton structural integrity

Core Design Contradiction:

Loss of informationVSStrength

Solution Approach 1:

The display window is formed by a displaceable flap that can be pushed inward, creating a flexible viewing aperture. This flexible membrane approach maintains the overall structural integrity of the carton while providing a clear display area for the article, resolving the contradiction between visibility and strength.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The displaceable flap creates a dynamic opening that can move inward when accessed. This dynamic feature allows the display window to maintain its structural role when closed while providing viewing access when needed, balancing the competing requirements of strength and visibility.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If openings are provided in the top and bottom walls for article adjustment, then the orientation of the article can be changed, but the security and containment of the article within the carton is reduced

Engineering Contradiction:

Improvearticle orientation adjustmentVSAvoidarticle containment security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The openings are strategically positioned and sized to allow preliminary insertion and orientation adjustment of the article during packaging, but are not designed to allow removal of the main body. This preliminary action approach enables orientation control while maintaining secure containment during the critical packaging phase.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Different regions of the carton have different properties: the top and bottom openings are localized features that permit limited access for orientation adjustment, while the rest of the carton structure maintains full containment. This local quality differentiation allows orientation flexibility without compromising overall security.

Inventive Principle:

Principle #3Local quality

3Loss of substance

If the carton is formed from minimal material for cost and environmental considerations, then material usage is reduced, but the strength and suitability for holding large weights is compromised

Engineering Contradiction:

Improvematerial usageVSAvoidweight-bearing capacity

Core Design Contradiction:

Loss of substanceVSStrength

Solution Approach 1:

The carton utilizes curved surfaces and rounded corners in its panel design, which distribute stress more effectively than sharp angles. This curvature approach allows the use of minimal material while maintaining the strength required to hold large weights, resolving the contradiction between material efficiency and load-bearing capacity.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The carton panels are designed to utilize the full potential of paperboard material through optimized thickness distribution and structural geometry. By concentrating material where structurally critical and using minimal material where less critical, the design achieves high weight-bearing capacity with minimal overall material usage.

Inventive Principle:

Principle #40Composite materials

4Ease of operation

If a displaceable flap with nonlinear fold line is used for the display window, then the flap can be easily displaced for access, but the manufacturing precision and assembly difficulty increase

Engineering Contradiction:

Improveflap displacement easeVSAvoidnonlinear fold line precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The nonlinear fold line is segmented into multiple linear or simple curved sections rather than a single complex curve. This segmentation makes the fold line easier to manufacture with standard scoring equipment while still achieving the desired nonlinear displacement behavior when the flap is pushed, balancing ease of operation with manufacturing feasibility.

Inventive Principle:

Principle #1Segmentation

AI summary

Aspects of the disclosure relate to a carton for packaging one or more articles, a blank for forming the carton and a method of packaging articles. The carton may have at least one display window for presentation of an article therein. The carton comprises a plurality of panels forming walls of a tubular structure including a top wall, a first side wall, a base wall, and a second side wall. The carton comprises an end closure structure for partially closing an end of the carton. The end closure structure comprises a top end closure flap hingedly connected to the top wall. At least one side end closure flap is hinged to a corner panel by a first fold line. The corner panel is hinged to one of the first and second side walls by a second fold line.
