Solution Overview

Problem

Conventional refrigerators lack the ability to provide users with interactive and bidirectional information flow, limiting their functionality to mere storage and not offering a convenient user interface for managing stored items or providing additional information such as recipes and user memos.

Innovation Solution

A refrigerator equipped with a display unit on one of the doors that includes a memory for storing information about items and a controller to display icons indicating the types and quantities of items, allowing users to input and manage data through a touch screen interface, enabling features like food management, recipe suggestions, and temperature control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a refrigerator is designed to provide only basic storage functionality, then the device complexity is low, but the information provision capability and user interaction are limited

Engineering Contradiction:
Improveinformation provision capabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The refrigerator is designed to perform multiple functions beyond basic storage, including displaying stored item information, providing recipe suggestions, enabling user interaction through touch screens, and communicating with external devices. This multi-functionality approach allows the refrigerator to serve as both a storage device and an information hub, resolving the contradiction between versatility and complexity by integrating various functions into a single unified system

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

2Adaptability or versatility

If a unidirectional information system is implemented, then the device complexity is low, but the user interaction and information processing capability are limited

Engineering Contradiction:
Improveuser interaction capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The refrigerator implements a bidirectional information flow system where users can input information through touch screens and receive processed information in return. The system provides feedback by displaying stored item details, recipe suggestions based on stored items, and allowing users to interact with the system to modify settings or request information. This feedback mechanism enables meaningful user interaction while maintaining manageable system complexity through structured information exchange protocols

Inventive Principle:
Principle #23Feedback

3Ease of operation

If no visual information display is provided, then the device complexity is low, but the user accessibility and information availability are limited

Engineering Contradiction:
Improveuser accessibilityVSAvoidinterface complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The refrigerator introduces a display device as an intermediary between the storage system and the user. This intermediary component presents information about stored items in a user-friendly visual format, including item names, quantities, and expiration dates. The display acts as a mediator that translates raw storage data into meaningful visual information, improving user accessibility without requiring complex direct interaction with the storage mechanisms themselves

Inventive Principle:
Principle #24Intermediary (Mediator)
