Solution Overview

Problem

There is no suitable way to pre-package cocktails, making it difficult to customize and efficiently prepare mixed drinks.

Innovation Solution

A dual-compartment shaker system consisting of a top can and a bottom can, where the top can contains a solute (such as alcohol or sweetener) and the bottom can contains a solvent (such as mixer or base ingredient), allowing for customizable mixing and consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Duration of action of stationary object

If cocktails are pre-packaged in separate compartments, then shelf life and portability are improved, but mixing customization and preparation efficiency are worsened

Engineering Contradiction:
Improveshelf lifeVSAvoidmixing customization
Core Design Contradiction:
Duration of action of stationary objectVSEase of operation

Solution Approach 1:

The cocktail is divided into multiple compartments within a single package, with each compartment containing a different ingredient (solute or solvent). This segmentation allows the ingredients to be stored separately to extend shelf life while still enabling the user to mix them in customizable ratios by controlling how much is transferred from each compartment.

Inventive Principle:
Principle #1Segmentation

2Weight of moving object

If cocktails are pre-packaged in separate compartments, then portability is improved, but preparation complexity is worsened

Engineering Contradiction:
ImproveportabilityVSAvoidpreparation complexity
Core Design Contradiction:
Weight of moving objectVSDevice complexity

Solution Approach 1:

Multiple compartments are nested within a single outer package, with each compartment containing a different cocktail ingredient. This nested structure improves portability by consolidating multiple ingredients into one compact unit while the user interface simplifies the preparation process, allowing users to mix cocktails by simply opening compartments and pouring, rather than managing multiple separate containers.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If dual-compartment shaker system is used, then mixing ratios can be customized, but device complexity increases

Engineering Contradiction:
Improvemixing ratiosVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shaker system includes dynamic elements such as movable partitions or adjustable pouring controls that allow users to customize mixing ratios on-the-fly. The partition can be moved to different positions to control the flow rate or volume transferred from one compartment to another, providing adaptability in mixing ratios while keeping the overall device structure relatively simple.

Inventive Principle:
Principle #15Dynamics

AI summary

A shaker for housing and dispensing food or drink items. The shaker has a top can sitting atop a bottom can. Each can contains a separate component. The top can is removed and its contents are added to the second can. This allows the user to control how much of the contents from the top can are added to the bottom can. A single multi-compartment vessel houses two separate ingredients and prevents their mixing.
