Solution Overview

Problem

Refrigeration appliances like ice makers, refrigerators, and freezers lack advanced interfaces for control and maintenance, making it difficult to efficiently interact with and manage their operating parameters without significantly increasing their cost.

Innovation Solution

A portable electronic device is used to connect with refrigeration appliances via wireless communication protocols like Bluetooth or Wi-Fi, allowing users to control, diagnose, and maintain these devices remotely, eliminating the need for costly full interfaces on each appliance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If advanced interfaces like keyboards and large displays are added to refrigeration appliances, then user control capability and maintenance ability are improved, but appliance cost increases to an uncompetitive level

Engineering Contradiction:
Improveuser control capabilityVSAvoidappliance cost
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent introduces a portable electronic device as an intermediary between the user and the refrigeration appliance. The portable device contains the complex interface elements (display, keyboard, processing logic) while the appliance itself remains simple with only basic control circuitry. This mediator approach allows rich user interaction capabilities without burdening the appliance with costly components.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The complex interface functionality is extracted from the refrigeration appliance and placed into a separate portable electronic device. The appliance retains only the essential control receiver and actuator components, while the display, input methods, and processing logic are removed to the portable device, reducing appliance complexity and cost.

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If sophisticated control interfaces are integrated into refrigeration appliances, then functionality and user experience are enhanced, but manufacturing cost and price increase significantly

Engineering Contradiction:
ImprovefunctionalityVSAvoidmanufacturing cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The portable electronic device serves multiple functions: it acts as a remote control, a diagnostic tool, a maintenance guide, and an information display device. By consolidating these diverse functionalities into a single universal interface device, the system achieves high adaptability without requiring multiple specialized components in the appliance itself.

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

Solution Approach 2:

The portable device serves as a universal mediator that can interact with various refrigeration appliance models through standardized communication protocols. This intermediary layer provides versatility and adaptability across different appliance types without requiring each appliance to have custom-built complex interfaces.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of manufacture

If simple interfaces are used in refrigeration appliances, then manufacturing cost is reduced, but user ability to control and maintain appliances is limited

Engineering Contradiction:
Improvemanufacturing costVSAvoiduser control capability
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The portable electronic device acts as an intermediary that compensates for the simplicity of the appliance interface. It provides the user with advanced control capabilities, diagnostic functions, and maintenance guidance that would otherwise require complex hardware integrated into the appliance, thereby maintaining low manufacturing costs while enhancing user capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Ease of operation

If extensive interfaces and control systems are built into refrigeration appliances, then user interaction capability is improved, but device complexity and price become uncompetitive

Engineering Contradiction:
Improveuser interaction capabilityVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The complex interface elements (display screen, keyboard, processing logic, diagnostic algorithms) are extracted from the refrigeration appliance and relocated to a portable electronic device. The appliance itself is left with a simple receiver and actuator system, dramatically reducing device complexity while preserving full user interaction capability through the portable intermediary.

Inventive Principle:
Principle #2Taking out (Extraction)
