Touch LCD Washing Machine Interface for Real-Time Program Customization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines lack user customization and information accessibility, requiring users to replace machines or download new programs for additional functions, and struggle to provide real-time information about their operational states.
Innovation Solution
A washing machine equipped with a full-touch Liquid Crystal Display (LCD) for network communication, displaying real-time weather information, recommending wash programs, and showing energy and water usage, along with a sensor to detect user presence and adjust screen colors based on energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a conventional washing machine with predetermined wash programs is used, then the machine structure remains simple, but the user cannot access real-time operational information and must replace the machine to add new functions
Solution Approach 1:
The patent introduces a display unit as an intermediary component that communicates with the washing machine's control system. This display unit provides real-time operational information (wash cycle progress, temperature, energy consumption) without requiring complex changes to the core washing machine structure. The display acts as a mediator between the machine's internal systems and the user, solving the information accessibility problem while maintaining structural simplicity.
2Adaptability or versatility
If the washing machine provides predetermined wash programs, then the device complexity is low, but the adaptability to user preferences and weather conditions is poor
Solution Approach 1:
The patent implements dynamic wash programs that can be adjusted based on real-time weather information and user preferences. The control system allows users to modify wash parameters (temperature, time, intensity) during operation, and automatically adjusts programs based on weather data received via communication module. This dynamic adaptability enhances versatility without requiring complete redesign of the control system.
Solution Approach 2:
The washing machine is designed with multi-functional capabilities including weather-based program selection, energy consumption monitoring, real-time information display, and network communication. These multiple functions are integrated into a unified system that can perform various tasks through a single device, reducing the need for separate specialized machines while maintaining manageable complexity.
3Loss of information
If the display shows detailed operational information continuously, then the user can monitor wash cycles in real-time, but the energy consumption increases
Solution Approach 1:
The display unit operates using periodic updating rather than continuous display. Information is refreshed at specific intervals (e.g., every 30 seconds or at key wash cycle milestones) rather than continuously. This periodic action maintains real-time monitoring capability for the user while significantly reducing the energy consumption of the display system compared to continuous operation.
Data Source
AI summary
A washing machine to provide a user interface environment using a full-touch LCD to perform communication over a network and a method of controlling the same. It is possible to provide a user interface by simple and convenient touch manipulation and display information regarding a user manipulation state and an operation state of the washing machine according to various visual/tactile tastes.
