Solution Overview

Problem

Existing carton designs lack effective reinforcement and protection for beverage containers, leading to potential breakage during handling and storage, especially when filled with fragile items.

Innovation Solution

A carton design incorporating a reinforcing insert and article protection features, such as flaps and handles, formed from a carton blank and insert blank, which provides structural support and cushioning to prevent container movement and breakage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a simple carton structure is used, then manufacturing cost and complexity are reduced, but protection and reinforcement of beverage containers deteriorate

Engineering Contradiction:
Improvecarton manufacturing simplicityVSAvoidcontainer protection capability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The carton is divided into two functional parts: a simple carton body for basic containment and a separate reinforcing insert for protection. The insert is segmented into end panels that fit into recesses at the carton ends, providing targeted reinforcement where containers are most vulnerable during handling and storage.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The reinforcing insert acts as an intermediary element between the simple carton structure and the beverage containers. It provides the necessary protection and reinforcement without requiring the entire carton structure to be complex, solving the contradiction by introducing a specialized component that mediates between structural simplicity and protection capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If reinforcement inserts are added to protect containers, then container protection improves, but device complexity increases

Engineering Contradiction:
Improvecontainer protection capabilityVSAvoidcarton structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Reinforcement is applied locally only where needed - at the ends of the carton where containers are most susceptible to damage. The end panels of the insert provide targeted protection without adding complexity to the entire carton structure, allowing protection enhancement with minimal increase in overall device complexity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The reinforcing insert is nested within the carton structure, with end panels fitting into recesses formed in the carton end walls. This nesting approach allows the insert to be integrated into the existing carton form without requiring a complete redesign of the carton structure, thus limiting the increase in device complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If article protection flaps are included, then container protection improves, but manufacturing complexity increases

Engineering Contradiction:
Improvearticle protectionVSAvoidcarton blank complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The article protection flaps are merged with the reinforcing insert as an integrated component rather than separate elements. The flaps are formed as part of the insert blank, which is then inserted into the carton as a single unit. This combining approach provides protection functionality while reducing the number of separate components that would need to be manufactured and assembled.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A carton for holding a plurality of containers. The carton comprises a plurality of panels comprising a top panel. A plurality of end flaps are at least partially overlapped with respect to one another to thereby 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 and at least one reinforcing end panel foldably connected to the central panel. At least one reinforcing end flap can be foldably connected to the at least one reinforcing end panel. A handle can comprise at least a first handle feature in the top end flap and a second handle feature in the reinforcing end panel. The second handle feature can be generally aligned with the first handle feature.
