Control method for a kitchen appliance system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complexity of kitchen appliance systems for preparing dishes, with multiple appliances requiring coordinated operation, leads to user difficulty in maintaining the correct sequence of steps, especially with limited display control, resulting in increased effort and potential errors.
Innovation Solution
A central control device with a user input interface and data interface that allows for the selection and adjustment of appliance functions, featuring a collapsible overview field to provide optimal control and visibility of all connected appliances, enabling automatic processing of recipe steps across multiple kitchen appliances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If multiple kitchen appliances are networked to form a kitchen appliance system for semi-automated preparation, then the automation capability and functionality are improved, but the system complexity and difficulty of control increase
Solution Approach 1:
The user interface is segmented into multiple selectable views (first view showing all appliances, second view showing single appliance details). This allows the complex system information to be divided into manageable portions, enabling users to overview the entire appliance system at once or focus on individual appliance controls as needed, thereby reducing perceived complexity while maintaining full automation capability
Solution Approach 2:
The user interface dynamically switches between different display modes based on user selection. The system can transition from a comprehensive overview mode showing all networked appliances to a detailed single-appliance mode, providing adaptability that simplifies interaction with complex multi-appliance systems while preserving full system functionality
2Area of stationary object
If a small display is used for controlling the kitchen appliance system, then the device portability and compactness are improved, but the overview capability and user control efficiency deteriorate
Solution Approach 1:
The interface uses temporal dimension to compensate for spatial limitations. Instead of showing all information simultaneously on a small display, the system provides different views that can be selected over time - a first view for comprehensive appliance overview and a second view for detailed single-appliance control, allowing full information access despite limited display area
Solution Approach 2:
The control interface is segmented into multiple discrete views or modes. The first view segments information to show all networked appliances in a compact format, while the second view segments focus on a single appliance with full control options, allowing the small display to efficiently present different levels of information hierarchy without overwhelming the user
3Adaptability or versatility
If manual intermediate steps are required between recipe steps on different kitchen appliances, then the flexibility and adaptability are improved, but the sequence maintenance difficulty and user effort increase
Solution Approach 1:
The system provides feedback by displaying the current recipe step status and the sequence of operations across multiple appliances. The user interface shows which appliance should be operated next and what step is currently active, giving users feedback about the expected sequence while still allowing manual intervention when needed, thereby reducing the cognitive effort required to maintain the correct sequence
