Full-Touch LCD User Interface for Network-Connected Washing Machines
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
3Loss of information
If comprehensive state information is displayed in real-time, then information availability is improved, but display complexity and energy consumption increase
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.
