Solution Overview

Problem

Conventional cold brew coffee systems require manual water refilling, occupy valuable countertop space, and fail to maintain the brewing water at a cooled temperature, resulting in unsatisfactory coffee and the need for post-brew chilling.

Innovation Solution

A brewing assembly integrated into a refrigerator appliance, featuring a dispensing assembly for chilled water, a pitcher with an upper and lower reservoir, and a brew module with canisters for slow water infusion, allowing for automated cold brew coffee production within a chilled environment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a dedicated cold brew coffee system is used, then cold brewing capability is provided, but countertop space is occupied and manual water refilling is required

Engineering Contradiction:
Improvecold brewing capabilityVSAvoidcountertop space
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent combines the cold brew brewing system with an existing refrigerator appliance, integrating the brewing functionality into the refrigerator's existing structure. The brewing chamber is positioned within the refrigerator cabinet space, utilizing the refrigerator's internal volume rather than requiring separate countertop space. This merging of functions eliminates the need for a dedicated standalone cold brew system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The refrigerator appliance is designed to serve multiple functions: food storage and cold beverage brewing. The brewing assembly utilizes the refrigerator's existing cooling capability and water supply system, allowing the same appliance to perform both traditional refrigeration and specialized cold brew preparation without requiring additional dedicated equipment.

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

2Ease of manufacture

If conventional cold brew systems are used, then brewing is possible, but water temperature cannot be maintained at cold levels during brewing

Engineering Contradiction:
Improvebrewing functionalityVSAvoidwater temperature maintenance
Core Design Contradiction:
Ease of manufactureVSTemperature

Solution Approach 1:

The brewing system is integrated with the refrigerator's existing cooling mechanism. The brewing chamber is positioned within the refrigerator cabinet where it benefits from the ambient cold environment. The refrigerator's cooling system continuously maintains the brewing water at cold temperatures throughout the brewing process, eliminating the need for separate temperature control mechanisms.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If cold brew systems are used, then cold brewing is achieved, but post-brew chilling is required to reach desired temperature

Engineering Contradiction:
Improvebrewing capabilityVSAvoidchilling time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The system performs preliminary cooling by maintaining the brewing water at cold temperatures before and during the brewing process. The refrigerator's cooling system pre-cools the water and continuously maintains it at the desired temperature throughout brewing, eliminating the need for post-brew chilling and allowing immediate consumption of cold brewed beverages.

Inventive Principle:
Principle #10Preliminary action

4Ease of manufacture

If manual water refilling is used, then system operation is possible, but user convenience is reduced

Engineering Contradiction:
Improvesystem operationVSAvoiduser convenience
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The brewing system leverages the refrigerator's existing water supply infrastructure. The brewing chamber is fluidly connected to the refrigerator's water dispensing system, allowing automatic water supply during brewing. The system uses the refrigerator's existing water storage and dispensing capabilities, eliminating the need for manual water refilling operations.

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