Solution Overview

Problem

Existing tea machines for automatic tea preparation are cumbersome, difficult to manage, and prone to contamination, with complex handling and cleaning processes that often require partial disassembly and can impair the taste of tea.

Innovation Solution

A tea machine with a tea strainer insert that can be fully immersed in the brewing chamber, featuring a guide section and a scraping device to facilitate easy insertion and removal of tea leaves, and a spray head with adjustable outlet nozzles for effective cleaning, minimizing contamination and simplifying the brewing and cleaning processes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a tea machine uses a perforated base to support the cup during brewing, then the brewing process is simplified, but the perforated base becomes difficult to keep clean and contaminates the cup bottom

Engineering Contradiction:
Improvebrewing process simplicityVSAvoidcontamination of cup bottom
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the cup support function from the brewing chamber floor by introducing a separate, removable cup support element. This element can be easily removed and cleaned separately, preventing contamination of the cup bottom while maintaining the simplified brewing process. The support element is taken out as a distinct component that does not interfere with the brewing chamber's cleanliness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The brewing chamber is segmented into functional zones: the brewing chamber floor remains clean and dedicated to brewing, while the cup support function is provided by a separate, removable element. This segmentation allows the support element to be cleaned independently without affecting the brewing chamber's hygiene, thus eliminating contamination risks.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If tea machines have two chambers for brewing and separating tea leaves, then tea leaf removal is simplified, but the machine becomes very bulky

Engineering Contradiction:
Improvetea leaf removalVSAvoidmachine size
Core Design Contradiction:
Ease of operationVSVolume of moving object

Solution Approach 1:

The invention merges the brewing chamber and tea leaf separation functions into a single integrated chamber. The cup support element serves dual purposes: supporting the cup during brewing and facilitating tea leaf removal after brewing. This eliminates the need for a separate second chamber, reducing machine size while maintaining ease of tea leaf removal.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The cup support element is designed with multi-functionality: it supports the cup during the brewing process, enables easy tea leaf removal after brewing, and can be cleaned separately. This single element performs multiple functions that would otherwise require separate chambers, thus reducing the overall machine volume.

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

3Reliability

If tea machines require partial disassembly for cleaning, then thorough cleaning is achieved, but the handling becomes complex

Engineering Contradiction:
Improvecleaning thoroughnessVSAvoidcleaning process simplicity
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The cup support element is extracted as a removable component that can be easily taken out for cleaning. This allows thorough cleaning of all surfaces that contact tea or water without requiring disassembly of the main machine structure. The support element can be cleaned separately in the dishwasher or by hand, simplifying the cleaning process while maintaining thoroughness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The cup support element is designed to be preliminarily positioned in a way that facilitates easy removal and cleaning. Its structure allows it to be easily detached before cleaning is needed, and it can be placed in the dishwasher or cleaned by hand without requiring complex disassembly procedures.

Inventive Principle:
Principle #10Preliminary action
