Solution Overview

Problem

Existing insulated beverage holders fail to effectively insulate multiple opened beverage cans and facilitate easy carrying without spilling, especially in warm outdoor conditions.

Innovation Solution

A sleeve with an insulated material and a design that allows stacking of cans, featuring a base wall, peripheral wall, and a lip with tabs to securely hold multiple cans, including a seal to prevent spilling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple beverage cans are carried in hands, then convenience of carrying multiple beverages is improved, but the cans become difficult to control and spill contents when opened

Engineering Contradiction:

Improveease of carrying multiple beverage cansVSAvoidstability of beverage can contents

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent combines multiple beverage cans into a single integrated holder structure where multiple cans are secured within one unit. The holder includes a body with multiple compartments and a common lid that seals all cans simultaneously, merging the function of carrying multiple separate cans into a single stable unit that prevents spilling when opened.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The holder structure serves multiple functions simultaneously: it carries multiple beverage cans, insulates them from external temperatures, prevents spilling through a common lid seal, and allows easy removal of individual cans while maintaining stability. This multi-functionality resolves the contradiction by providing both ease of carrying and content stability within a single device.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If beverage cans are carried in hands during outdoor events, then portability is improved, but the contents quickly get warm in warm weather

Engineering Contradiction:

Improveportability of beverage cansVSAvoidtemperature of beverage can contents

Core Design Contradiction:

Ease of operationVSTemperature

Solution Approach 1:

The holder incorporates insulating materials within its structure to create a thermal barrier between the external environment and the beverage cans. This composite construction includes the holder body, insulating layers, and sealing components that work together to maintain cool temperatures for the beverages while allowing easy portability.

Inventive Principle:

Principle #40Composite materials

Solution Approach 2:

The holder acts as an intermediary structure between the beverage cans and the external warm environment. It provides a protective enclosure with insulating properties that mediates the thermal interaction, keeping the cans cool during transport and storage at outdoor events while maintaining ease of carrying.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If vendors open all beverage cans at the point of sale, then service efficiency is improved, but the opened cans become difficult to carry and control

Engineering Contradiction:

Improveservice efficiency of beverage dispensingVSAvoidease of carrying opened beverage cans

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The holder merges multiple opened cans into a single organized unit with a common lid that remains sealed. This allows vendors to efficiently open multiple cans at the point of sale while the holder structure maintains an organized, stable configuration that is easy to carry and control, preventing the difficulty associated with carrying separate opened cans.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The holder is designed to receive and secure cans in a pre-organized configuration before the user needs to carry them. The structure includes pre-formed compartments and sealing mechanisms that prepare the cans for easy carrying immediately after opening, eliminating the need for the user to manually organize multiple opened cans.

Inventive Principle:

Principle #10Preliminary action

AI summary

A beverage insulation device for insulating and carrying a stack of beverage cans includes a sleeve having a base wall and a peripheral wall that is coupled to and extends upwardly from the base wall to define an interior space. The sleeve is cylindrical to receive a first can. The sleeve includes an insulated material for insulating contents of the first can from outside temperatures. A lip coupled to and extending downwardly from the base wall defines a cavity. The cavity is cylindrical to receive a second can. A plurality of tabs is coupled to and extends outwardly from the lip into the cavity. The plurality of tabs engage an outer perimeter of the annular lip of the second can to releasably retain the top surface of the second can within the cavity wherein the first can is stackable over the second can.
