Water-guiding domestic appliance and method for operating a water-guiding domestic appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dishwasher loading methods require manual arrangement based on intuition, often necessitating verbal instructions or supervision, and are not tailored to individual households, with general instructions being unsuitable due to reliance on standard place settings, and there is a risk of loading unsuitable items for cleaning.
Innovation Solution
A dishwasher equipped with a detection unit that identifies the type and position of items being loaded using sensors and image recognition, providing users with signal output for optimal placement, potentially assisted by a robot, and includes a memory unit for storing and comparing arrangements to suggest energy-efficient and environmentally friendly loading configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual arrangement based on intuition is used, then the appliance structure remains simple, but the ease of operation deteriorates and loading precision is poor
Solution Approach 1:
The detection unit automatically detects items and the control unit autonomously determines optimal positions and provides guidance, enabling the system to serve itself rather than requiring manual arrangement knowledge from the user
Solution Approach 2:
The patent replaces manual mechanical arrangement with an automated detection and guidance system using sensors, image recognition, and electronic output devices to determine and communicate optimal item positions
2Adaptability or versatility
If general instructions based on model standard place setting are used, then the device complexity remains low, but the adaptability to individual households deteriorates
Solution Approach 1:
The system automatically adapts to each household's specific items by detecting them and providing customized arrangement instructions, eliminating the need for pre-programmed standard place settings
Solution Approach 2:
The detection unit varies the detected parameters (item type, size, shape, material) to generate customized arrangement instructions specific to each household's unique set of items rather than using fixed standard settings
3Manufacturing precision
If verbal instruction or supervision is required, then the manufacturing precision of arrangement is improved, but the ease of operation deteriorates
Solution Approach 1:
The output unit provides immediate visual or acoustic feedback to the user about the correct position for each detected item, enabling precise arrangement without requiring external verbal instructions or supervision
Solution Approach 2:
The patent replaces the need for human-to-human verbal communication with an automated electronic communication system between the detection unit and output unit, providing precise arrangement guidance directly to the user
4Productivity
If automatic detection and positioning is implemented, then the productivity of loading is improved, but the device complexity worsens
Solution Approach 1:
The system automatically detects items, determines their optimal positions, and guides placement without requiring external assistance, thereby improving loading productivity despite the added detection and control components
