Solution Overview

Problem

Existing electric tea makers lack user control over the brew process, particularly in adjusting water temperature and brew time, which is crucial for optimizing tea flavor, as different teas require specific conditions and users have varying preferences for brew strength.

Innovation Solution

A semi-automatic electric tea maker with a vessel that can heat water to various temperatures, features a tea brewing chamber with a perforated lower and unperforated upper portion, and a plunger that isolates tea from the water, allowing users to select brew temperatures and durations, with sensors and timers to prompt the brewing process initiation and termination, and maintain the tea at a drinking temperature.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single device is designed to provide both heating and brewing control functions, then device versatility is improved, but device complexity increases

Engineering Contradiction:
Improvedevice versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functions (heating, temperature control, brewing timing, and tea isolation) into a single integrated device. The vessel includes a heating element, temperature sensor, timer, and plunger mechanism all working together in one unit, eliminating the need for separate kettle and tea maker devices.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The device is designed to perform multiple functions: heating water to various temperatures, maintaining drinking temperature, timing the brewing process, and isolating tea leaves. This multi-functional design allows one device to replace several separate appliances.

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

2Ease of operation

If automatic temperature control and timing features are added to the device, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device automatically monitors its own state through sensors (temperature and chamber position) and autonomously controls the heating element and timer without requiring user intervention. The system self-regulates to maintain the brewing process according to pre-set parameters.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Temperature sensors and chamber position sensors provide continuous feedback to the control system, which adjusts heating and timing accordingly. This closed-loop control ensures accurate temperature maintenance and precise brewing duration without complex user input.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If the chamber design includes both perforated and unperforated portions, then brewing control precision is improved, but device complexity increases

Engineering Contradiction:
Improvebrewing control precisionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The chamber is designed with different properties in different regions: the lower portion has perforations for water flow and tea infusion, while the upper portion is unperforated to contain and isolate the tea leaves. This spatial differentiation of properties enables precise control over the brewing process.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The chamber is divided into functionally distinct segments (perforated lower portion and unperforated upper portion) that work together to achieve controlled brewing. The segmentation allows independent optimization of water flow characteristics and tea containment.

Inventive Principle:
Principle #1Segmentation

AI summary

An electric tea maker device has a vessel with a reservoir having an opening that removably receives a tea brewing chamber. The chamber has an upper portion and a lower portion. The upper portion lacks perforations and the lower portion has perforations. The device has a plunger for the chamber that, when in a depressed position within the chamber, isolates tea from the reservoir. The vessel has a sensor for detecting when the chamber is inserted into the reservoir in a brewing position, a brew countdown timer that is activated by the sensor, and an indicator for alerting a user that a brew countdown is complete.
