Solution Overview

Problem

Existing cartons fail to effectively reduce the movement of beverage containers near the carton ends, leading to potential container instability and breakage during handling and storage.

Innovation Solution

A carton design featuring a reinforcing insert with a central panel, foldably connected reinforcing end and side flaps, and compression tabs that form a shoulder and inwardly folded structure to securely hold containers, reducing movement and enhancing stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a simple carton structure without reinforcing insert is used, then the device complexity is reduced, but the stability of containers near carton ends deteriorates

Engineering Contradiction:
Improvecontainer stabilityVSAvoidcarton structure complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The reinforcing insert is divided into multiple functional segments: a central panel for structural support, end flaps for securing containers at carton ends, and side flaps for lateral reinforcement. This segmentation allows each component to address specific stability issues without requiring complete structural redesign of the entire carton.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reinforcing insert is nested within the carton structure, with the central panel positioned inside the carton body and flaps extending to engage with container surfaces. This nested configuration provides reinforcement without adding external bulk, maintaining compactness while enhancing container stability.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Stability of the object's composition

If a reinforcing insert with multiple flaps is added to reduce container movement, then container stability improves, but the ease of manufacture deteriorates

Engineering Contradiction:
Improvecontainer stabilityVSAvoidcarton assembly ease
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The reinforcing insert is pre-assembled with the central panel and flaps connected through fold lines before insertion into the carton. This preliminary assembly ensures proper alignment and reduces assembly complexity during final carton construction, as the insert arrives as a pre-formed unit ready for installation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The flaps are designed with fold lines that allow dynamic adjustment during assembly, enabling workers to easily fold and position the flaps into their final configuration. This dynamic design simplifies the assembly process compared to rigid, pre-folded structures that would require complex tooling.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the distal portion of the reinforcing end flap overlaps the top end flap, then container movement restriction improves, but the device complexity increases

Engineering Contradiction:
Improvecontainer movement restrictionVSAvoidflap configuration complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The overlapping configuration is applied locally only at the distal portion of the reinforcing end flap where it engages with the top end flap and containers. This localized overlap provides targeted reinforcement at the critical container-end interface without requiring complex configurations throughout the entire flap structure.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The distal portion of the reinforcing end flap merges with the top end flap through overlapping, creating a combined structural unit that reinforces both the carton end and container simultaneously. This merging eliminates the need for separate reinforcement components, simplifying the overall configuration while enhancing movement restriction.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A carton can comprise a plurality of panels that extends at least partially around an interior of the carton and comprises a top panel, a bottom panel, a first side panel, and a second side panel. A plurality of end flaps are respectively foldably connected to respective panels of the plurality of panels and at least partially form a closed end of the carton. The plurality of end flaps can comprise a top end flap foldably connected to the top panel. A reinforcing insert can comprise a central panel, a reinforcing end flap, and a reinforcing side flap. The central panel at least partially overlaps the top panel, the reinforcing side flap is foldably connected to the central panel, and the reinforcing end flap comprises a proximal portion foldably, an intermediate portion, and a distal portion. The distal at least partially overlaps the top end flap.
