Solution Overview

Problem

Home and small environment brewers are limited in brew modes, often unable to switch between single serve and batch brewing without component exchange, lack a variable bloom phase, and suffer from inconsistent hot water temperatures, resulting in lower quality beverages.

Innovation Solution

A coffee brewer with a multimode showerhead and processing system that allows switching between single serve and batch modes without component exchange, incorporates variable bloom and brew phases, and maintains a constant hot water temperature through a processing component that controls water flow and temperature dynamically.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a home coffee brewer is designed for single serving brewing, then it cannot brew multiple serving batches, and vice versa

Engineering Contradiction:
Improvebrew mode versatilityVSAvoidcomponent exchange requirement
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The showerhead is designed with multiple nozzle configurations that can be selectively activated to perform different brewing functions. The same showerhead component can deliver water for single serving brewing, multiple serving batch brewing, and bloom phases by controlling which nozzles are open or closed, eliminating the need for component exchange while achieving multi-functionality.

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

Solution Approach 2:

The system dynamically controls the showerhead nozzle configuration during operation. A processing component selectively opens or closes different portions of the nozzle array based on the desired brew mode, allowing the static physical component to achieve dynamic functional adaptability between single serve and batch brewing modes.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If a coffee brewer provides a bloom phase feature, then it requires manual processing or primitive bloom capability

Engineering Contradiction:
Improvebloom phase capabilityVSAvoidmanual processing requirement
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs the bloom phase as a preliminary automated action before the main brewing process. The processing component automatically controls water delivery through specific nozzle configurations to create the bloom phase conditions, eliminating the need for manual intervention while providing sophisticated bloom capability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The showerhead dynamically switches between different nozzle configurations to automatically execute the bloom phase followed by the brewing phase. The processing component controls the timing and water flow patterns to provide automated variable bloom phases with different durations and water volumes.

Inventive Principle:
Principle #15Dynamics

3Reliability

If hot water temperature is maintained constantly, then brewing quality improves, but temperature fluctuation occurs in traditional brewers

Engineering Contradiction:
Improvetemperature consistencyVSAvoidhot water temperature stability
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The processing component monitors and controls water temperature during the brewing process, using feedback mechanisms to maintain constant temperature despite variations in water flow rates and environmental conditions. This ensures reliable temperature consistency for high-quality brewing.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system adjusts water flow parameters and heating parameters dynamically to maintain constant temperature. By changing flow rates and heating power in coordination, the system compensates for temperature fluctuations and maintains stable brewing conditions.

Inventive Principle:
Principle #35Parameter changes

AI summary

A coffee brewer can include a main body, water tank, filter box, and multimode showerhead. The water tank can provide water for brewing. The filter box can receive water and coffee brewing materials, brew coffee, and dispense brewed coffee from a filter box outlet. The multimode showerhead can be at the filter box and can operate in multiple different brew modes including a first brew mode for brewing a single serving of coffee and a second brew mode for brewing a multiple serving batch of coffee. The multimode showerhead can include nozzles that dispense water within the filter box. A first portion of the nozzles can be open and dispense water while a second portion of the nozzles can be closed and not dispense water when the showerhead operates in the first brew mode. All nozzles can be open when the showerhead operates in the second brew mode.
