Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Refrigerators lack the ability to receive and execute voice commands effectively, limiting their functionality in providing personalized content and services to users, especially in tasks like internet shopping and user identification.
Innovation Solution
Incorporating a microphone, display, and controller with speech recognition technology, allowing the refrigerator to understand and execute voice commands, transmit data to servers for analysis, and provide relevant information or services based on user input, including identifying users and managing storage compartment contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If speech recognition technology is added to enable voice command input, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The refrigerator's display device serves multiple functions: it displays operational information, receives touch inputs, and now also functions as a speech recognition interface. By making the display multi-functional, the system enables voice command input without adding separate dedicated hardware components, thus improving ease of operation while minimizing the increase in device complexity.
Solution Approach 2:
The speech recognition functionality is merged with the existing display device rather than being implemented as a separate component. The controller integrates speech recognition processing with the display's existing control functions, combining multiple capabilities into a single unified interface that reduces overall system complexity.
2Adaptability or versatility
If multiple sensors and communication modules are integrated to provide personalized services, then adaptability is improved, but device complexity increases
Solution Approach 1:
The display device is designed as a universal interface that handles multiple types of user inputs (touch, speech) and provides multiple types of information (operational status, personalized recommendations, shopping lists). This multi-functionality enables the refrigerator to adapt to different user preferences and interaction methods without requiring separate dedicated components for each function.
Solution Approach 2:
The controller acts as an intermediary that receives data from various sensors and communication modules, processes this information, and presents it through the unified display interface. This mediator approach allows the system to integrate multiple data sources and communication protocols while maintaining a simple user-facing interface, thus improving adaptability without proportionally increasing complexity.

AI summary
A refrigerator comprises a storage compartment configured to store food, a temperature detector configured to detect an internal temperature of the storage compartment, a cooler configured to supply cool air to the storage compartment, a microphone configured to receive a speech, a display configured to display information, at least one processor configured to be electrically connected to the temperature detector, the microphone, and the display; and a memory configured to be electrically connected to the at least one processor. The memory stores at least one instructions configured to, when a first speech including a food name is recognized via the microphone, allow the processor to display a food list, which comprises food information corresponding to the food name and an identification mark identifying the food information, on the display, and configured to, when a second speech referring to the identification mark is recognized via the microphone, allow the processor to display food purchase information corresponding to the identification mark, on the display.
