Solution Overview

Problem

Conventional refrigerators lack a user-friendly interface for providing and processing information related to stored items and their storage conditions, limiting their ability to offer bidirectional communication and smart functionality.

Innovation Solution

A refrigerator equipped with a display device that includes a memory for storing item information, a controller for displaying icons representing items, and a communication unit for bidirectional information exchange, allowing users to input and retrieve data on stored items, recipes, and operational settings through a touch-sensitive interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a refrigerator is equipped with a display device and communication unit for bidirectional information exchange, then user accessibility and information processing capability are improved, but device complexity increases

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

Solution Approach 1:

The display device serves multiple functions: displaying storage chamber information, showing stored items, providing recipes, enabling bidirectional communication, and allowing user input through touch interface. This multi-functionality improves ease of operation while avoiding the need for multiple separate devices that would increase complexity.

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

Solution Approach 2:

The display device acts as an intermediary between the user and the refrigerator system, providing a touch-sensitive interface that simplifies user interaction. It mediates between the user's needs and the complex internal systems of the refrigerator, making operation easier without requiring the user to understand the underlying complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a display device with touch-sensitive interface and communication unit is added to the refrigerator, then information processing capability is improved, but manufacturing cost increases

Engineering Contradiction:
Improveinformation processing capabilityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The display device is designed to perform multiple information processing functions including displaying storage chamber data, showing stored items, providing recipes, enabling bidirectional communication, and accepting user input. This multi-functionality achieves high adaptability and information processing capability while avoiding the cost of implementing multiple separate systems.

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

Solution Approach 2:

The display device automatically receives and transmits information related to stored items, storage conditions, and operational settings without requiring manual intervention. It self-manages the information processing tasks, reducing the need for additional manual systems and lowering manufacturing costs.

Inventive Principle:
Principle #25Self-service

3Reliability

If a cover member is detachably provided to cover the display device, then protection of the display device is improved, but ease of operation is slightly reduced

Engineering Contradiction:
Improveprotection of display deviceVSAvoidease of operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The display device is segmented from the main refrigerator body by being detachably covered with a cover member. This segmentation allows the display device to be protected when not in use while remaining easily accessible when needed. The cover member can be independently attached or removed without affecting the rest of the refrigerator system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cover member is designed to be detachable rather than fixed, making the protection system dynamic. The cover can be attached to protect the display device and removed when the user needs to access or interact with the display, thus balancing protection with ease of operation.

Inventive Principle:
Principle #15Dynamics
