Solution Overview

Problem

Existing brewing systems are unsuitable for cold water extraction methods, as they require hot water and are not portable or suitable for small-scale domestic use, making it difficult to prepare and store beverages like coffee using cold water extraction effectively.

Innovation Solution

A portable beverage preparation system comprising a cold water extraction chamber, a beverage storage chamber, and a drip band with a manual actuator to control liquid flow, allowing for the preparation and storage of beverages using cold water extraction, with features like a porous mesh and double-wall insulated container to maintain freshness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If traditional coffee brewing systems (coffeemakers, espresso machines, cafetieres) are used, then hot water brewing is achieved, but they are inappropriate for cold water extraction as they require hot water or boiling point temperatures

Engineering Contradiction:

Improvewater temperatureVSAvoidsuitability for cold water extraction

Core Design Contradiction:

TemperatureVSAdaptability or versatility

Solution Approach 1:

The system is specifically designed to operate with cold water (room temperature or below) rather than hot water, changing the temperature parameter from traditional brewing methods. The extraction chamber and filtration system are configured to enable effective extraction at lower temperatures through extended contact time and controlled flow rates.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If cold water extraction is used for 12-24 hours, then beverages with fewer chemicals and better flavor are produced, but traditional systems are not portable or suitable for small-scale domestic use

Engineering Contradiction:

Improvebeverage quality and health benefitsVSAvoidequipment complexity and portability

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system is divided into separate functional modules: an extraction chamber for cold water brewing, a portable filtration system, and a storage container. This segmentation allows the complex cold extraction process to be performed in stages using simple, transportable components rather than requiring a single complex appliance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A portable filtration system acts as an intermediary between the cold water extraction process and the final beverage storage. The filter enables effective separation of extracted beverage from grounds using simple gravity flow, making the system portable and suitable for domestic use without requiring complex pumping or pressure mechanisms.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Productivity

If filter coffee systems are used with cold water, then brewing is possible, but water passes through filters too fast for effective cold water extraction

Engineering Contradiction:

Improvebrewing speedVSAvoidextraction effectiveness

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The filtration system uses a dynamic flow control mechanism where water flow rate is automatically regulated by the filter medium itself. The porous structure and capillary action create variable resistance that maintains optimal flow velocity for cold extraction, preventing both too-fast and too-slow flow rates regardless of water volume or container orientation.

Inventive Principle:

Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables simple, effective preparation and storage of beverages using cold water extraction, maintaining flavor and health benefits, and ensuring the beverage remains fresh for extended periods due to temperature-dependent solubility of chemicals.

Implementation Method 1

a porous mesh dividing the granule compartment and the cold water compartment. Typically, the porous mesh has pores of a size selected such that cold water is able to pass there through to mix with granules within the granule compartment whereas granules contained within the granule compartment are not able to pass into the cold-water compartment

Methodology Applied

Scientific EffectFiltration: Filter (physical)

Implementation Method 2

In particular examples of the system, the beverage storage chamber comprises a double-wall insulated drinking container

Methodology Applied

Scientific EffectThermal insulation: Thermal Insulation

Implementation Method 3

Producing beverages by cold water extraction, for example at room temperature for say twelve to twenty-four hours, can naturally filter out high temperature soluble chemicals such as fatty acids, caffeine and oils

Methodology Applied

Scientific EffectTemperature-dependent solubility: Solvation
