Solution Overview

Problem

Existing container carriers fail to consistently engage and stabilize containers of varying diameters and sidewall qualities, often resulting in a loose or skewed package.

Innovation Solution

A carrier with perforations across the inner web that forms a 'V' shape when applied, ensuring consistent contact with the containers' sidewalls and preventing skewing or inverting, constructed from a thermoplastic material with apertures arranged in rows and ranks, and a flap extending into each aperture to enhance friction and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional carrier design is used, then the carrier can be applied to containers, but the package becomes loose or skewed when containers of varying diameters and sidewall qualities are used

Engineering Contradiction:
Improvecompatibility with various container diameters and sidewall qualitiesVSAvoidpackage tightness and compactness
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The inner web is designed to be flexible and adaptable, allowing it to dynamically adjust its shape and contact points when applied to containers of varying diameters. The web can flex and conform to different sidewall qualities while maintaining consistent contact, enabling the carrier to adapt to various container sizes without compromising package stability or compactness.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the carrier is applied to smaller diameter containers, then the carrier can accommodate different container sizes, but the inner web may skew or invert

Engineering Contradiction:
Improveability to accommodate various container diametersVSAvoidinner web geometry stability
Core Design Contradiction:
Adaptability or versatilityVSShape

Solution Approach 1:

The inner web incorporates asymmetric features including a flap extending into the container aperture and a specific geometric configuration that prevents skewing. The web's asymmetric design allows it to maintain its shape and orientation when applied to smaller diameter containers, preventing the common problem of skewing or inverting while still accommodating various container sizes.

Inventive Principle:
Principle #4Asymmetry

3Stability of the object's composition

If the inner web is made rigid to maintain shape, then the package structure is stable, but the carrier cannot adapt to various container diameters

Engineering Contradiction:
Improvepackage structure stabilityVSAvoidadaptability to different container diameters
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The inner web is constructed as a flexible thin film or shell that can adapt to various container diameters while maintaining structural stability. The web's flexibility allows it to conform to different container sizes, and its thin film structure enables it to bend and flex without compromising the overall package structure or causing skewing.

Inventive Principle:
Principle #30Flexible shells and thin films

4Ease of manufacture

If the carrier uses a simple structure for easy manufacture, then production is straightforward, but the carrier cannot consistently engage containers of varying sizes

Engineering Contradiction:
Improvecarrier manufacturing simplicityVSAvoidconsistent container engagement
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The carrier is segmented into distinct functional components including the inner web, flaps, and container apertures, each designed to perform a specific function. This segmentation allows for straightforward manufacturing of individual components that can be assembled into a reliable carrier structure, enabling consistent engagement with containers of varying sizes while maintaining ease of manufacture.

Inventive Principle:
Principle #1Segmentation
