Solution Overview
Problem
Existing dishwasher control systems require manual selection of washing programs by users, which can lead to suboptimal performance due to the lack of automatic detection of load type and dirt type, potentially resulting in inefficient washing and drying.
Innovation Solution
A control method that uses a mobile device to record and process images of dishwasher contents, comparing them to prerecorded data on a server to automatically select the most suitable washing program based on load type and dirt type, while also providing layout suggestions and overload warnings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic image processing is implemented to detect load type and dirt type, then washing performance is improved, but device complexity increases
Solution Approach 1:
The patent introduces a server as an intermediary component that handles the complex image processing and program selection algorithms. The mobile device captures images and transmits them to the server, which then analyzes the images, determines load and dirt types, and selects appropriate washing programs. This mediator approach allows the dishwasher system to achieve automatic detection capabilities without embedding complex processing hardware directly in the appliance, thus improving washing performance while managing device complexity through distributed system architecture.
2Ease of operation
If manual program selection is replaced by automatic detection, then ease of operation is improved, but loss of information increases due to potential detection errors
Solution Approach 1:
The system implements feedback mechanisms where the server analyzes captured images using image processing algorithms to determine load type and dirt type, then selects washing programs accordingly. The system can provide feedback to users through the mobile device application, showing detected load characteristics and suggested programs. This feedback loop allows the system to operate automatically while maintaining information accuracy through continuous analysis and user verification capabilities, resolving the contradiction between ease of operation and information loss.
