Solution Overview

Problem

Common drip coffee machines produce coffee with a single concentration, failing to meet diverse taste preferences.

Innovation Solution

A flow diverting adjustment apparatus with movable flow blocking members and channels that allow selective communication or blocking of output channels to control the flow of liquid onto ground coffee, enabling the brewing of beverages with varying concentrations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single stream of water is injected onto the ground coffee, then the brewing process is simple, but the concentration of brewed coffee cannot be adjusted

Engineering Contradiction:
Improvecoffee concentration adjustmentVSAvoidflow control structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The single water stream is segmented into multiple output channels (first output channel, second output channel, third output channel) with different flow rates. Each channel can be independently controlled to adjust the total water flow onto the coffee grounds, enabling concentration adjustment without overwhelming complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flow blocking members are designed to be movable rather than fixed, allowing dynamic adjustment of channel blocking. This enables the system to transition between different brewing modes (single stream, split streams, blocked channels) to achieve variable coffee concentrations

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple output channels are provided to adjust coffee concentration, then different taste preferences can be satisfied, but the device structure becomes more complex

Engineering Contradiction:
Improvetaste preference adjustmentVSAvoidchannel and blocking member structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple flow blocking members are integrated into a single adjustment member that can simultaneously control multiple channels. This merging approach allows concentration adjustment while reducing the number of independent components and simplifying the overall device structure

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The adjustment member serves multiple functions: it controls the blocking state of different output channels, adjusts water flow distribution, and enables various brewing modes (strong, medium, light coffee). This multi-functionality reduces the need for separate components for each control function

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

AI summary

This application relates to a flow diverting adjustment apparatus and a coffee machine. The flow diverting adjustment apparatus includes: a flow diverting member, where the flow diverting member includes an input channel and at least two output channels, the output channels are capable of being in intercommunication, and the input channel is capable of being in communication with at least one of the output channels; and a flow blocking assembly, where the flow blocking assembly includes at least one flow blocking member, and the flow blocking member is movably connected to the flow diverting member, to cause the output channels to be in a communication state or a blocked state.
