Solution Overview

Problem

Existing washing machines lack user customization and real-time feedback, requiring users to replace machines or download new programs for additional features, and provide limited information on machine states, making it difficult for users to optimize energy and water usage.

Innovation Solution

A full-touch LCD user interface that allows network communication, displays various washing machine states, and adjusts display colors based on energy usage, providing customizable wash programs, real-time weather recommendations, and historical energy and water usage data, enabling users to select optimal wash cycles and receive stain removal advice.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a full-touch LCD with network communication is implemented, then user interface capability and information display are improved, but device complexity and manufacturing cost increase

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

Solution Approach 1:

The full-touch LCD screen serves multiple functions: it displays wash course information, shows real-time washing status, provides weather forecasts, displays energy consumption data, and enables network communication. This multi-functionality consolidates what would otherwise require separate components into a single integrated unit, improving ease of operation while controlling the increase in device complexity.

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

2Adaptability or versatility

If real-time weather information and network communication are added, then adaptability and user customization are improved, but device complexity and energy consumption increase

Engineering Contradiction:
ImproveadaptabilityVSAvoidenergy consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by fetching and storing weather forecast data and energy consumption information in advance. The full-touch LCD displays this pre-fetched data during operation, allowing the washing machine to adapt to weather conditions and provide energy-saving recommendations without requiring continuous real-time network communication, thus reducing energy consumption while maintaining adaptability.

Inventive Principle:
Principle #10Preliminary action

3Loss of information

If comprehensive state information is displayed in real-time, then information availability is improved, but display complexity and energy consumption increase

Engineering Contradiction:
Improveinformation availabilityVSAvoiddisplay energy consumption
Core Design Contradiction:
Loss of informationVSUse of energy by stationary object

Solution Approach 1:

The full-touch LCD updates display information periodically rather than continuously. It shows comprehensive state information including wash course details, real-time washing status, and energy consumption data at appropriate intervals during the washing cycle. This periodic updating provides users with necessary information while avoiding the excessive energy consumption that would result from continuous real-time display updates.

Inventive Principle:
Principle #19Periodic action
