Solution Overview

Problem

Conventional laundry machines and home appliances face challenges in extending their functionality without requiring hardware modifications or additional user interface components, which limits their ability to communicate externally for remote management and control, making it difficult to provide users with convenient and efficient operation.

Innovation Solution

Incorporating a WiFi communication module and a separate display controller into the appliance, allowing for remote management services through an external terminal, enabling communication with a server for extended functions like remote control, diagnosis, and firmware updates without altering the existing control panel.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional user interface components are added to extend functionality, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvefunctionality extensionVSAvoidhardware modification
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an external terminal as an intermediary device that provides the additional user interface components. The external terminal communicates with the laundry machine via WiFi, allowing functionality extension without modifying the laundry machine's hardware. The external terminal acts as a mediator that bridges the user and the laundry machine, enabling features like remote control, monitoring, and firmware updates through a smartphone or tablet application.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If communication modules are integrated into the appliance, then adaptability is improved, but manufacturing cost increases

Engineering Contradiction:
Improveremote communication capabilityVSAvoidproduction cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

Instead of integrating expensive WiFi communication modules into every laundry machine, the patent uses the user's existing smartphone or tablet as an intermediary communication device. This approach leverages the communication capabilities already present in the user's device, eliminating the need for additional communication hardware in the laundry machine and significantly reducing manufacturing costs.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent makes the user's smartphone or tablet serve multiple functions: it acts as a remote control, a monitoring station, a firmware update device, and a communication bridge. By utilizing the universal communication capabilities of the user's existing device, the system avoids the need for dedicated communication hardware in the laundry machine, thereby reducing production costs while maintaining remote communication functionality.

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

3Adaptability or versatility

If the control panel is modified to enable remote management, then adaptability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveremote management capabilityVSAvoiduser interface complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The external terminal serves as an intermediary that handles all the complexity of remote management operations. Users interact with a simplified application interface on their smartphone or tablet, while the external terminal manages the complex communication protocols, authentication, and control signal transmission to the laundry machine. This separates the user interface complexity from the user, maintaining ease of operation.

Inventive Principle:
Principle #24Intermediary (Mediator)
