Solution Overview

Problem

Existing cartons struggle to accommodate articles of different shapes and sizes efficiently, leading to inefficiencies in packaging and storage.

Innovation Solution

A carton design featuring multiple panels and lids that can be configured between two arrangements, allowing for adjustable interior space and closure mechanisms to accommodate various sizes and shapes, with optional handles for ease of handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single fixed configuration of carton is used, then the structure is simple and easy to manufacture, but it cannot accommodate articles of different shapes and sizes efficiently

Engineering Contradiction:
Improveability to accommodate different article shapes and sizesVSAvoidcarton structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The carton incorporates movable partitions that can be repositioned between different locations within the carton interior. These partitions are configured to be movable relative to the carton walls, allowing the internal configuration to be dynamically adjusted. This enables a single carton structure to accommodate articles of varying shapes and sizes by repositioning the partitions, thereby resolving the contradiction between adaptability and structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The carton is divided into multiple compartments by introducing partitions that segment the interior space. These partitions create separate sections within the carton, allowing flexible arrangement of articles with different dimensions. The segmentation approach enables a single carton design to serve multiple storage configurations, improving adaptability without requiring multiple different carton types.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple carton configurations are maintained for different article sizes, then adaptability improves, but inventory management complexity increases

Engineering Contradiction:
Improveability to accommodate different article sizesVSAvoidinventory management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single carton design is created that can serve multiple functions by incorporating movable partitions. This universal carton can be configured to accommodate different article sizes and shapes through the repositioning of partitions, eliminating the need for maintaining separate inventory for different carton configurations. The multi-functionality approach simplifies inventory management while preserving adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If excess packaging space is provided for all possible article sizes, then all article types can be accommodated, but packaging efficiency decreases

Engineering Contradiction:
Improveaccommodation of various article sizesVSAvoidpackaging material waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

Instead of providing fixed excessive space for all possible article sizes, the carton uses movable partitions that can be repositioned to create the exact amount of space needed for the specific article being packaged. This dynamic adjustment eliminates wasted packaging material while maintaining the ability to accommodate various article sizes, resolving the contradiction between adaptability and packaging efficiency.

Inventive Principle:
Principle #15Dynamics

AI summary

A carton for holding one or more articles. The carton can comprise a plurality of panels that extends at least partially around an interior of the carton, and at least a first lid and a second lid. Each of the first lid and the second lid can be respectively foldably connected to one or more panels of the plurality of panels, and at least one of the first lid and the second lid can extend along at least a portion of a top end of the carton when the top end of the carton is closed. The carton can be configurable between a first arrangement and a second arrangement, and the top end of the carton can be wider in the first configuration than in the second configuration.
