Solution Overview

Problem

Current beverage machines are not optimized for brewing tea, as the method of using hot water with coffee brew baskets results in immediate water flow-out, reducing tea or fruit tea concentration and failing to match traditional brewing methods.

Innovation Solution

A beverage machine with an adjustable brewing device that controls water outlet speed through a movable cover plate with a soft sealing layer, allowing for different brewing times and concentrations by opening or closing water discharge holes, enabling the same device to brew both coffee and tea effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the coffee brew basket is used to brew tea with the same method as coffee, then the brewing process is simple and quick, but the water flows out immediately and the tea concentration is too low

Engineering Contradiction:
Improvebrewing speedVSAvoidtea concentration
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The brewing device incorporates a movable cover plate that can dynamically adjust the number of open water discharge holes during the brewing process. This dynamic adjustment allows the system to control water flow rate in real-time, enabling both quick brewing when needed and extended steeping when high concentration is desired, thus resolving the contradiction between brewing speed and tea concentration.

Inventive Principle:
Principle #15Dynamics

2Speed

If the water outlet speed is fast, then the brewing process is efficient and quick, but the tea cannot infuse properly and concentration is reduced

Engineering Contradiction:
Improvewater outlet speedVSAvoidtea concentration
Core Design Contradiction:
SpeedVSQuantity of substance

Solution Approach 1:

The brewing device changes the parameter of water outlet speed by adjusting the number of open discharge holes through the movable cover plate. By varying this parameter during brewing, the system can optimize water flow rate to match different tea brewing requirements, allowing both fast effusion and proper infusion to be achieved as needed.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the same brewing device is used for both coffee and tea, then the device versatility is improved, but the brewing parameters cannot be optimized for different beverage types

Engineering Contradiction:
Improvedevice versatilityVSAvoidbrewing parameter optimization
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The brewing device is designed with a movable cover plate mechanism that provides multiple brewing modes, making it universally applicable to different beverage types including coffee and various tea varieties. The adjustable water discharge holes allow the single device to optimize brewing parameters for each beverage type, achieving both versatility and brewing precision.

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

AI summary

This invention provides a beverage machine which comprises a machine housing and a brewing chamber arranged on the upper part of this machine housing, a brewing device for receiving the brewing material being provided in this brewing chamber, characterized in that an adjustment device is provided on the brewing device with which the water outlet speed of this brewer is set when brewing a beverage. Because the adjusting device adjusts the water outlet speed of the brewing device when brewing a drink, the same brewing device can be used to brew different drinks, for example tea or fruit drinks, etc., and at the same time it can be realized that different brewing times for the brewed goods in the brewing device make drinks be produced with different concentrations to meet the different tastes of users.
