Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Integrated vapor extraction devices in kitchen appliances are not intuitive for users due to the need for symbol or text-based parameter settings, making it difficult for users to understand the correlation between the display and the extraction device.
Innovation Solution
A kitchen appliance with a hob and integrated vapor extraction device featuring a display device that includes a lighting system with an output surface, where the output surface is arranged in the area of the vapor extraction device, allowing for intuitive information display and minimizing the number of parts required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a display element is provided in the hob plate for the extractor device, then information can be displayed to the user, but the correlation between the display and the extractor device is not intuitive and requires symbols or text
Solution Approach 1:
The patent uses LED lights that visually copy or mimic the appearance of the extractor device components (such as the chimney or housing) to display operational status. Instead of using abstract symbols or text, the display elements replicate the physical form of the extractor device parts, making the correlation immediately recognizable and intuitive for users.
Solution Approach 2:
The patent employs different colors of LED lights to indicate different operational states of the extractor device. By changing the color of the displayed elements rather than using text or symbols, the system provides intuitive visual feedback that is easily understood by users without requiring interpretation of text labels.
2Ease of operation
If the output surface extends over the edge of the extractor device, then information display is simplified and made more visible, but the structure becomes more complex
Solution Approach 1:
The patent merges the display function with the existing structural elements of the extractor device by extending the output surface over the edge of the housing or frame. This integration allows the display to utilize the device's own structure rather than requiring separate mounting components, thereby improving visibility while minimizing additional structural complexity.
Solution Approach 2:
The edge of the extractor device housing or frame serves multiple functions: it provides structural support for the extractor device and simultaneously acts as the mounting surface for the display output. This multi-functionality eliminates the need for separate display mounting structures, reducing overall device complexity while maintaining excellent visibility.
3Area of stationary object
If the extractor device is integrated into the hob, then space is saved and the appliance becomes more compact, but the display correlation becomes less intuitive
Solution Approach 1:
By integrating LED display elements directly into the extractor device housing that is embedded in the hob, the system creates visual copies of the extractor components within the compact hob structure. This allows the display to maintain direct spatial and visual correlation with the extractor device even in the integrated configuration, preserving intuitiveness while achieving space savings.
