Method for voice control on microwave oven, and microwave oven

Solution Overview

Problem

Conventional microwave ovens lack the ability to smartly learn user habits, requiring repeated parameter settings for the same recipes, leading to inefficiency in cooking processes.

Innovation Solution

A method and apparatus for controlling a microwave oven by voice, which includes receiving voice instructions, searching for pre-stored default recipe parameters, and updating them based on user inputs, allowing the oven to learn and adapt to user preferences by acquiring and generating default recipe parameters through image recognition and tutorial guidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a microwave oven only provides basic heating functions with simple controls, then the device complexity is low and ease of manufacture is high, but the ease of operation deteriorates because users must repeatedly set parameters manually without smart learning capabilities

Engineering Contradiction:

Improveease of operationVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The microwave oven automatically learns and stores user-preferred cooking parameters for different recipes through voice interactions and operational data collection. The system performs self-service by autonomously updating its recipe database without requiring manual reconfiguration, thereby improving ease of operation while managing device complexity through automated functions.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical parameter setting with voice recognition and automated electronic control systems. Users can issue voice commands to set cooking parameters, and the system automatically processes and stores these preferences, substituting physical panel adjustments with intelligent voice-based interaction and electronic learning mechanisms.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If the microwave oven implements smart learning functions to remember user preferences, then the ease of operation improves by reducing repeated parameter settings, but the device complexity increases due to additional learning and memory components

Engineering Contradiction:

Improveease of operationVSAvoiddevice complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The microwave oven automatically learns and stores user-preferred cooking parameters for different recipes through voice interactions and operational data collection. The system performs self-service by autonomously updating its recipe database without requiring manual reconfiguration, thereby improving ease of operation while managing device complexity through automated functions.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system implements feedback mechanisms by monitoring user interactions, analyzing operational patterns, and automatically adjusting recipe parameters based on observed preferences. This closed-loop learning process enables the microwave to adapt to user habits over time, improving ease of operation through intelligent automation despite increased device complexity.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If the microwave oven collects and processes user interaction data to learn cooking habits, then the adaptability improves by personalizing recipe parameters, but the loss of information increases due to data storage and processing requirements
