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

The integration of a WiFi communication module and a separate display controller in the laundry machine allows for remote management services through an external terminal, enabling communication with a server for extended functions and convenient operation without requiring additional hardware changes or user access to the appliance.

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 and versatility are improved, but the device complexity and manufacturing cost increase

Engineering Contradiction:
ImprovefunctionalityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a server as an intermediary between the laundry machine and the user's external terminal (smartphone, tablet, or PC). The server handles complex processing, storage, and control logic remotely, allowing the laundry machine itself to remain simple while still providing advanced functionalities such as remote monitoring, control, and extended features through communication networks

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent extracts complex control panel functions and additional features from the physical laundry machine and relocates them to a remote server. This extraction allows the laundry machine to maintain its original simple hardware configuration while gaining access to extended functionalities through network communication, effectively separating the intelligence from the appliance

Inventive Principle:
Principle #2Taking out (Extraction)

2Adaptability or versatility

If additional hardware components are added to the laundry machine to enable remote communication, then the adaptability is improved, but the manufacturing cost increases

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

Solution Approach 1:

The patent utilizes existing universal communication infrastructure (WiFi modules, mobile communication networks, and standard network protocols) that are already present in modern laundry machines for basic operations. By leveraging these existing communication capabilities, the system can establish remote connections without adding specialized expensive hardware, as the same communication interfaces serve multiple purposes

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

Solution Approach 2:

The system leverages the user's existing personal terminal devices (smartphones, tablets, PCs) which already possess communication capabilities, processing power, and user interface functions. These personal devices perform many of the communication and control tasks that would otherwise require dedicated expensive hardware in the laundry machine itself

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the control panel is made more complex to provide extended functions, then the versatility is improved, but the ease of operation deteriorates due to excessive concentration and knowledge required

Engineering Contradiction:
Improveextended functionsVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The server acts as an intelligent intermediary that handles complex control logic, processing, and decision-making remotely. The user interacts with a simplified interface on their personal terminal, while the server manages the complexity of extended functions, thereby maintaining ease of operation while providing versatile capabilities

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

Instead of placing complex controls and interfaces on the laundry machine's control panel, the patent inverts the approach by providing the interface on the user's personal terminal device. This reversal allows the laundry machine to receive simple commands while the complex functionality is accessed and managed remotely through the user's familiar device

Inventive Principle:
Principle #13The other way round (Inversion)
