Solution Overview

Problem

Existing beverage container insulation systems fail to effectively maintain the temperature of beverages by preventing heat transfer and condensation without requiring the containers to be removed from their original packaging.

Innovation Solution

An insulation system comprising an inner container with stacked beverage cans, a water-resistant layer, and an outer container with an airspace and spacers, allowing the inner container to be transported while maintaining the temperature of the beverages.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If beverage containers are placed in conventional insulation systems, then heat transfer is reduced, but the containers must be removed from their original packaging which reduces convenience

Engineering Contradiction:

Improveheat transferVSAvoidconvenience

Core Design Contradiction:

Loss of energyVSEase of operation

Solution Approach 1:

The inner container is nested within the outer container, creating a compact insulation system that maintains beverage temperature while keeping the containers in their original packaging configuration. The inner container holds the beverage cans in stacked prone configuration, and the outer container provides insulation layering around it.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The insulation system is divided into distinct segments: the inner container for holding beverages, the water-resistant layer for condensation protection, and the outer container for structural insulation. This segmentation allows each component to perform its specific function while maintaining overall convenience.

Inventive Principle:

Principle #1Segmentation

2Reliability

If insulation material is added to prevent condensation, then thermal resistance is improved, but device complexity increases

Engineering Contradiction:

Improvecondensation preventionVSAvoidinsulation system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The water-resistant layer is applied specifically to the inner container surface where condensation occurs, providing localized protection exactly where needed. This targeted approach prevents condensation without requiring complex insulation throughout the entire structure.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The insulation system uses composite material layering with the water-resistant layer on the inner container and insulation material in the airspace between containers. This composite structure achieves effective condensation prevention and thermal resistance through material properties rather than complex mechanical design.

Inventive Principle:

Principle #40Composite materials

3Loss of energy

If air space is created between containers for insulation, then thermal resistance is improved, but volume of the system increases

Engineering Contradiction:

Improvethermal resistanceVSAvoidsystem volume

Core Design Contradiction:

Loss of energyVSVolume of stationary object

Solution Approach 1:

The beverage containers are arranged in a stacked prone configuration, transitioning from vertical to horizontal orientation. This dimensional change allows air spaces to be created between containers in the insulation system without significantly increasing the overall volume, as the containers nest together more efficiently in the horizontal arrangement.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

An insulation system for beverage containers comprising: an inner container surrounding a plurality of cylindrical beverage containers contained in an inner container; a handle included in an inner container top panel; an outer container having a cavity defined in the outer container for receiving the inner container; a pair of lateral spacers disposed lengthwise along corresponding inner upper corners of the out container; an airspace defined between an inner container side panel and an external container side panel having a polygon cross-section; and, a handle access opening centrally defined in an outer container top panel allowing access to the handle of the inner container so that the beverage containers, inner container and out container can be transported using the handle wherein the width of the handle access opening is about one third the length of the outer panel top opening.
