Container Carrier Handle Assembly Without Adhesives

Solution Overview

Problem

Existing carriers for holding and displaying containers lack efficient structural designs that allow for secure attachment of handle portions without the need for adhesives, limiting their versatility and ease of use.

Innovation Solution

A carrier design featuring a container receiving portion and a handle portion, where end flaps of the handle portion are positioned between panels of the container receiving portion to securely attach the two components, allowing for adhesive-free assembly and enhanced user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If adhesives are used to attach the handle portion to the container receiving portion, then the attachment strength is improved, but the ease of manufacture and environmental friendliness deteriorate

Engineering Contradiction:

Improveattachment strengthVSAvoidease of manufacture

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The carrier structure performs its own attachment function through the interlocking geometry of the handle portion and container receiving portion. The end flaps of the handle portion are positioned between the side panel and end flaps of the container receiving portion, creating a self-securing mechanism that eliminates the need for external adhesives or fasteners.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the chemical attachment mechanism (adhesives) with a mechanical interlocking system. The handle portion and container receiving portion are designed with complementary geometries that physically lock together through the end flap configuration, providing attachment strength without chemical bonds.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Strength

If adhesives are used to attach the handle portion to the container receiving portion, then the attachment strength is improved, but the environmental impact deteriorates

Engineering Contradiction:

Improveattachment strengthVSAvoidenvironmental impact

Core Design Contradiction:

StrengthVSObject-generated harmful factors

Solution Approach 1:

The carrier structure performs its own attachment function through the interlocking geometry of the handle portion and container receiving portion. The end flaps of the handle portion are positioned between the side panel and end flaps of the container receiving portion, creating a self-securing mechanism that eliminates the need for external adhesives or fasteners.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the chemical attachment mechanism (adhesives) with a mechanical interlocking system. The handle portion and container receiving portion are designed with complementary geometries that physically lock together through the end flap configuration, providing attachment strength without chemical bonds.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If a complex attachment mechanism is used to secure the handle portion, then the reliability is improved, but the device complexity increases

Engineering Contradiction:

Improveattachment reliabilityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The carrier is divided into distinct functional segments: the container receiving portion with its end flaps and the handle portion with its end flaps. This segmentation allows each component to be optimized independently while maintaining simple, reliable attachment through their interlocking geometries.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The carrier structure performs its own attachment function through the interlocking geometry of the handle portion and container receiving portion. The end flaps of the handle portion are positioned between the side panel and end flaps of the container receiving portion, creating a self-securing mechanism that eliminates the need for external adhesives or fasteners.
