Solution Overview

Problem

Existing carriers for containers lack efficient and robust mechanisms for holding and displaying multiple containers while providing clear visibility and easy access, often resulting in materials waste and inefficient structural integrity.

Innovation Solution

A carrier design featuring foldable central panels with openings and attachment panels that allow partial face-to-face contact, combined with adhesive glue openings for secure container retention, enabling multiple points of attachment and easy access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If traditional carrier designs are used, then manufacturing is simpler, but structural integrity and container retention are insufficient

Engineering Contradiction:
Improvestructural integrityVSAvoidcarrier structure
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The carrier is divided into multiple panels (front, back, left, right, top, bottom) that are foldably connected along edges, creating a modular structure that provides both strength and controlled complexity. Each panel serves a specific structural function while maintaining overall coherence.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The foldable panel structure allows the carrier to collapse into a compact nested form when empty, and expand into a rigid structure when containers are inserted, optimizing both storage efficiency and structural integrity during transport.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Ease of operation

If carriers with limited openings are used, then container security is improved, but visibility and access are reduced

Engineering Contradiction:
Improvecontainer accessVSAvoidcontainer retention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The front and back panels each contain multiple separate openings positioned at different locations, allowing selective access to specific containers while maintaining security for others. This segmented approach enables both easy access and reliable retention simultaneously.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the carrier panels have different properties: areas with openings provide access and visibility, while solid areas maintain structural integrity and security. The local quality varies by location to optimize both access and retention functions.

Inventive Principle:
Principle #3Local quality

3Strength

If more material is used for carrier construction, then structural integrity is improved, but material waste increases

Engineering Contradiction:
Improvestructural integrityVSAvoidmaterial waste
Core Design Contradiction:
StrengthVSLoss of substance

Solution Approach 1:

The carrier transitions from a flat 2D blank to a 3D structured form through folding, maximizing the structural efficiency of the material used. The dynamic transformation allows the same material to provide both flat-pack efficiency and erected structural integrity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

By utilizing the third dimension through folding and panel elevation, the carrier achieves enhanced structural integrity without adding material in the horizontal plane. The vertical dimension created by folded panels provides structural strength while minimizing material consumption.

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

AI summary

A carrier for holding a plurality of containers includes a plurality of panels that includes a at least two central panels and at least one attachment panel configured to receive a portion of one or more containers of the plurality of containers. The at least two central panels include a first central panel foldably connected to a second central panel. The first central panel has at least one opening and a portion of the second central panel is exposed through the at least one opening when the first central panel and the second central panel are in at least partial face-to-face contact.
