Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing insulated beverage holders fail to efficiently hold multiple cans while maintaining the top can in a ready-to-drink position, prevent messes during consumption, and maintain can temperatures, due to structural limitations and inefficient sealing mechanisms.

Innovation Solution

A rigid can koozie with an internal spring mechanism that compresses and advances cans upward, allowing direct drinking from the top can while keeping multiple cans at desired temperatures, using a removable shoulder ring and insulated container.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a rigid holder is used to stack multiple cans, then multiple cans can be transported while stacked, but the device cannot allow direct drinking from the can without getting messy

Engineering Contradiction:

Improvenumber of cans heldVSAvoiddirect drinking convenience

Core Design Contradiction:

Quantity of substanceVSEase of operation

Solution Approach 1:

The holder is divided into multiple stacked receptacles (first receptacle, second receptacle, etc.), each capable of holding a separate can. This segmentation allows multiple cans to be held vertically while providing individual access to each can's opening, enabling direct drinking without mess while maintaining the ability to stack multiple containers.

Inventive Principle:

Principle #1Segmentation

2Quantity of substance

If aluminum cans are stacked in a holder, then multiple beverages can be carried, but the cans cannot be fully emptied without spilling

Engineering Contradiction:

Improvenumber of beverages carriedVSAvoidcomplete emptying capability

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The holder is designed to be tiltable, allowing the user to tilt the entire assembly to an inverted orientation. This dynamic positioning enables complete emptying of the cans by gravity, ensuring that even the last drops of beverage can be consumed without spilling outside the receptacle.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The cans are nested vertically within stacked receptacles, with each receptacle containing a can. This nested arrangement, combined with the tilting capability, allows systematic emptying of each can from bottom to top, ensuring complete utilization of all beverages without spillage.

Inventive Principle:

Principle #7Nested doll (Nesting)

3Ease of operation

If a flexible fabric koozie is used, then a single can can be held, but multiple cans cannot be stacked while drinking

Engineering Contradiction:

Improvesingle can holdingVSAvoidnumber of cans stacked

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The holder utilizes insulating material that provides both structural rigidity and thermal insulation properties. This composite structure enables the holder to maintain its shape while stacking multiple cans, unlike flexible fabric koozies, while still providing the insulation needed to maintain beverage temperature.

Inventive Principle:

Principle #40Composite materials

4Adaptability or versatility

If a removable base is used to swap can positions, then unopened cans can be consumed, but the consumed can is retained causing spills

Engineering Contradiction:

Improvecan position swappingVSAvoidbeverage spillage

Core Design Contradiction:

Adaptability or versatilityVSObject-generated harmful factors

Solution Approach 1:

The holder is designed with multiple receptacles arranged vertically, with the drinking opening positioned at the top. This preliminary arrangement of receptacles eliminates the need for base swapping to access unopened cans, as the top receptacle naturally provides access to the top can while maintaining proper drainage orientation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The holder can be tilted to an inverted orientation for complete emptying, reversing the normal drinking position temporarily. This inversion allows all cans to be fully emptied by gravity, preventing spillage that would occur with traditional swapping mechanisms.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A rigid plural beverage can holder has an internal spring to advance contained beverage cans upward to a selectively removable can shoulder ring. The can shoulder ring retains the top most beverage can top exposed while securing the beverage can within the can holder, thereby enabling a person to drink directly from the top of the top-most can. The can shoulder ring is selectively removable from the beverage can holder to permit beverage cans to be selectively inserted into and removed from the beverage can holder. The beverage can holder preferably has insulated walls to help to maintain a desired temperature of the beverages held within the beverage cans.
