Solution Overview

Problem

Existing beverage shaker assemblies are inefficient, messy, and require frequent cleaning due to unreliable seals, often preparing excess quantities and necessitating a transfer step from shaker to serving cup, leading to spills and inefficiency.

Innovation Solution

A shaker cup assembly that forms a watertight seal with various serving cup sizes, allowing beverages to be shaken and served in the same cup, reducing the need for transfer and cleaning by using a shaker cup with concentric ridges and a lid that forms a seal with the assembly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a traditional shaker assembly is used with separate serving cups, then beverage mixing function is achieved, but the assembly requires frequent cleaning and is messy due to unreliable seals

Engineering Contradiction:
Improveseal reliabilityVSAvoidcleaning frequency
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The shaker cup assembly is designed to work with multiple serving cup sizes through concentric ridges that accommodate different diameters. The seal mechanism universally adapts to various cup sizes while maintaining reliable sealing, eliminating the need for multiple specialized shaker assemblies and reducing cleaning frequency through consistent seal performance across all configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The serving cup is nested within the shaker cup assembly during the shaking process, with the serving cup's rim positioned between the concentric ridges. This nesting arrangement ensures the serving cup acts as both the container and sealing element, eliminating separate seal components that would require additional cleaning and maintenance.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Quantity of substance

If excess beverage quantities are prepared in traditional shakers, then sufficient beverage volume is ensured, but transfer steps are required leading to spills and inefficiency

Engineering Contradiction:
Improvebeverage volumeVSAvoidbeverage preparation efficiency
Core Design Contradiction:
Quantity of substanceVSProductivity

Solution Approach 1:

The shaker cup assembly merges the shaking container and serving cup into a single integrated system. The serving cup remains nested within the shaker cup throughout the shaking process, allowing the beverage to be shaken and served without transfer. This eliminates spill risk and improves preparation efficiency while ensuring accurate volume yields.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If a shaker cup accommodates multiple serving cup sizes, then versatility is improved, but the structure becomes more complex with multiple ridges

Engineering Contradiction:
Improveserving cup size compatibilityVSAvoidridge structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The shaker cup opening is segmented into multiple concentric ridges, each accommodating a specific serving cup size. This segmentation allows the single shaker cup to universally receive different cup sizes by positioning the cup rim between appropriate ridges, providing versatility without requiring multiple specialized assemblies.

Inventive Principle:
Principle #1Segmentation
