Solution Overview
Problem
Existing combination appliances with integrated cooking hobs and suction hoods lack user-friendly control and synchronization of cooking hob and extraction device operations, leading to suboptimal performance and convenience.
Innovation Solution
A combination appliance with a cooking hob featuring a recessed support surface, an integrated extraction device with controllable fans, and a control module that synchronizes fan operation with cooking hob parameters, allowing for adjustable suction and heat settings through a wireless interface and user-friendly voice control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the extraction device is integrated below the cooking hob support surface, then the appliance combines cooking and extraction functions in one unit, but the control of the extraction device becomes complex and not user-friendly
Solution Approach 1:
The patent combines the extraction device control with the existing cooking hob control unit. The control unit integrates both cooking hob parameters and extraction device parameters into a single interface, allowing users to control both functions through one unified system rather than separate controls, thereby simplifying the user experience while maintaining integrated functionality
Solution Approach 2:
The control unit is designed to serve multiple functions: it controls both the cooking hob operations and the extraction device operations. This multi-functional control interface eliminates the need for separate control systems, reducing complexity for the user while maintaining the versatility of having both cooking and extraction capabilities
2Productivity
If the fan sucks air through the recess in the support surface, then cooking vapors are effectively removed, but the support surface structure becomes more complex
Solution Approach 1:
The support surface is segmented by incorporating a recess that creates a dedicated air passage zone. This recess separates the structural support function from the air extraction function, allowing the fan to access cooking vapors through the recessed area without compromising the overall integrity of the support surface. The recess acts as a dedicated channel that simplifies the air extraction path while maintaining structural functionality
3Adaptability or versatility
If the extraction device operates independently, then it can function as an air filter, but it cannot synchronize with cooking hob operations for optimal performance
Solution Approach 1:
The extraction device is designed with dynamic control capabilities that allow it to adapt its operation mode. The control unit can switch between independent operation (for air filtration when cooking hob is not in use) and synchronized operation (when cooking hob is active). This dynamic switching enables the system to optimize extraction parameters based on whether the cooking hob is operating, thereby achieving both independent air filtration capability and synchronized optimal performance
