Solution Overview

Problem

Traditional French press coffee makers pour unwanted coffee oils and bitter-tasting foam into the cup, which can be detrimental to health and taste.

Innovation Solution

A brewing apparatus with a container featuring a sloped base and a spout located near the bottom, allowing the separation of coffee grounds from the liquid before pouring, thus preventing oils and foam from being poured into the cup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If coffee is poured from the top of the container, then the brewing process is simple and straightforward, but unwanted oils and foam are poured into the cup along with the coffee

Engineering Contradiction:
Improvesimplicity of pouringVSAvoidcoffee oils and foam in cup
Core Design Contradiction:
Ease of operationVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and removes the harmful elements (oils and foam) from the coffee stream by introducing a separate water injection system that directs a stream of water beneath the coffee surface, causing the oils and foam to separate and remain on the surface while only the purified coffee is poured into the cup

Inventive Principle:
Principle #2Taking out (Extraction)

2Ease of manufacture

If a traditional French press structure is used, then the device is simple and easy to manufacture, but it cannot prevent oils and foam from being poured into the cup

Engineering Contradiction:
Improvesimplicity of device structureVSAvoiddetrimental effects of coffee oils and foam
Core Design Contradiction:
Ease of manufactureVSObject-generated harmful factors

Solution Approach 1:

The patent introduces an intermediary substance (water) and an intermediary mechanism (injection system with nozzle) that acts as a mediator between the coffee in the container and the cup. This intermediary water stream separates the harmful oils and foam from the coffee, allowing the coffee to be poured without the harmful elements while maintaining a relatively simple device structure

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If coffee grounds are separated from liquid using a mesh filter, then the brewing process is efficient, but oils and foam still float on the surface and are poured into the cup

Engineering Contradiction:
Improveefficiency of separation processVSAvoidsurface oils and foam
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful floating oils and foam into a beneficial separation mechanism by injecting water beneath the coffee surface, which causes the oils and foam to rise and congregate on the surface in a controlled manner, allowing them to be easily left behind while the purified coffee is poured into the cup

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

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

The apparatus effectively separates coffee grounds from the liquid, preventing oils and foam from being poured, resulting in a healthier and more palatable beverage.

Implementation Method 1

The brewing apparatus also includes a spout for pouring the beverage out of the container, the spout having a tip and a bottom end. The bottom end of the spout is connected to the container generally above and near the upper point of the sloped base.

AI summary

An improved brewing apparatus for producing a French press beverage includes a container for a beverage material and a brewing liquid, which has a sloped base extending inwardly from an upper point on its sidewall to a lower point on its bottom wall. The brewing apparatus also includes a plunger assembly coupled to its lid that has a rod and a separation mechanism. A downward force on the rod advances the separation mechanism for separating the beverage material from the brewing liquid to produce the beverage. The brewing apparatus further includes a spout for pouring the beverage from the container that has a bottom end connected to the container generally above and near the upper point of the sloped base. The brewing apparatus also includes a stopper mechanism removably coupled to the spout tip for generally sealing the spout from the beverage material and the brewing liquid entering the spout.
