Solution Overview

Problem

Existing carriers for containers lack efficient and stable structures for holding and transporting multiple containers of varying shapes, particularly bottles and cans, without compromising on stacking stability and ease of handling.

Innovation Solution

A system comprising an upper and lower construct formed from blanks with container retention features and panels that securely hold containers, allowing for multi-ply support and tear resistance, with optional handle integration for enhanced grip and stacking capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a simple carrier structure is used, then manufacturing cost is reduced, but container retention stability deteriorates

Engineering Contradiction:
Improvecarrier manufacturing costVSAvoidcontainer retention stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The carrier is divided into multiple panels (front panel, back panel, side panels) that can be independently formed and assembled. Each panel contains specific container retention features tailored to its location, allowing the structure to be both manufacturable from flat blanks and stable when assembled to hold containers securely.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple container retention features are integrated within each panel structure, with features nested at different levels and depths. The panels themselves are nested within the overall carrier framework, creating a hierarchical structure that provides stable container retention while maintaining manufacturing efficiency.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If multiple container retention features are added to each panel, then container holding capability is improved, but panel complexity increases

Engineering Contradiction:
Improvecontainer holding capabilityVSAvoidpanel structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each panel is designed as a multi-functional unit that simultaneously provides structural support, contains multiple container retention features for different container sizes and shapes, and maintains structural integrity. The panels serve multiple purposes: they form the carrier framework, provide container retention, and can be assembled in various configurations.

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

3Stability of the object's composition

If panels extend around the interior for receiving containers, then stacking stability is improved, but vertical profile increases

Engineering Contradiction:
Improvestacking stabilityVSAvoidvertical profile
Core Design Contradiction:
Stability of the object's compositionVSLength of moving object

Solution Approach 1:

The panels extend around the interior in a three-dimensional configuration rather than simply adding vertical height. The side panels and front/back panels create a enclosed structure that provides stacking stability through lateral support and interlocking geometries, while minimizing the overall vertical profile by utilizing horizontal and angular dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
