Solution Overview

Problem

Conventional laundry machines and home appliances face challenges in extending their functions without modifying the existing control panel or hardware, due to space and cost constraints, and users often struggle to access and control these appliances remotely, especially when they are not in the same location.

Innovation Solution

A laundry machine equipped with a WiFi communication module and a separate display controller allows for remote management services through an external terminal, enabling communication with a server for extended functions and convenient operation without the need for physical access, using a setting mode for initial connection and a use mode for ongoing communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional functions are added to the laundry machine by modifying the control panel or hardware, then the functionality is extended, but the production cost increases and the device complexity increases

Engineering Contradiction:
Improvefunctionality extensionVSAvoidcontrol panel complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the system into three independent parts: the existing laundry machine (with its original control panel), a separate communication module (WiFi module), and an external terminal (smartphone). This segmentation allows the laundry machine to gain smart functions without modifying its original control panel or hardware structure, thus extending functionality while avoiding increased device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an external terminal (smartphone) as an intermediary between the user and the laundry machine. The terminal handles all interactions for extended functions, while the laundry machine only needs a simple communication module. This intermediary approach enables functionality extension without complicating the laundry machine's control system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If remote management service is implemented, then user convenience is improved, but the device complexity and production cost increase

Engineering Contradiction:
Improveremote access convenienceVSAvoidcommunication system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent implements a self-service remote management system where the external terminal (smartphone) autonomously handles all communication and control operations. The laundry machine's communication module only needs to provide basic network connectivity and receive commands, without requiring complex processing or interface capabilities. This self-service approach enables remote management while keeping the laundry machine's complexity minimal.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent uses inexpensive, widely available smartphones as the remote interface instead of building expensive dedicated remote control hardware into the laundry machine. The smartphone, being a common consumer device, provides all necessary communication and interface capabilities at minimal additional cost to the laundry machine system.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Adaptability or versatility

If the control panel is modified to support new functions, then the adaptability is improved, but the ease of manufacture deteriorates

Engineering Contradiction:
Improvefunction extension capabilityVSAvoidcontrol panel fabrication
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent separates the function extension capability from the original control panel by using an independent communication module and external terminal. This segmentation allows the laundry machine to be manufactured with its original simple control panel, while smart functions are added through the separate communication module, thus maintaining ease of manufacture while achieving adaptability.

Inventive Principle:
Principle #1Segmentation
