Solution Overview
Problem
Existing cooking devices in kitchen furniture face challenges in improving heating behavior and ease of cleaning, particularly in maintaining effective distance between heating plates and preventing contamination of heating elements.
Innovation Solution
A device with upper and lower heating plates that can move to adjust distance, featuring an induction heater and a detachable intermediate plate made of glass ceramic for easy cleaning, with the upper heating plate being vertically flexible and mounted for adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the heating plates are fixed in position, then the device structure is simple, but the heating behavior and cooking versatility are limited
Solution Approach 1:
The upper heating plate is made movable relative to the lower heating plate, allowing dynamic adjustment of the distance between them. This enables versatile cooking modes (grilling, toasting, warming) by varying the plate separation, while the movement mechanism remains integrated within the housing to avoid excessive complexity
2Ease of operation
If the heating plates are fixed together, then the device structure is stable, but the cleaning process becomes difficult and time-consuming
Solution Approach 1:
The heating assembly is segmented into separable components: the upper heating plate can be detached from the lower heating plate and removed independently. This allows the upper plate to be taken out for easy cleaning in the dishwasher, while the lower plate remains in the device. The detachable connection simplifies cleaning access without requiring complex disassembly mechanisms
3Length of stationary object
If the heating plates are positioned close together, then the device compactness is improved, but the heating effectiveness and food cooking quality deteriorate
Solution Approach 1:
The upper heating plate can be dynamically positioned at different distances from the lower heating plate. During cooking operations, sufficient distance can be maintained for effective heat transfer and food processing. When not in use, the plate can be retracted or positioned closer to minimize the device's overall height profile, balancing compactness with heating effectiveness
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances cooking versatility by allowing adjustable heating distances and easy cleaning through reversible attachment mechanisms, maintaining efficient heating performance while preventing contamination and facilitating dishwasher use.
Implementation Method 1
A heater and preferably an induction heater is arranged behind the upper and/or the lower heating plate
Implementation Method 2
The induction heating is preferably a current-carrying coil. Induction-based heating plates are advantageous, among other things, because of their quick response behavior and good energy yield.
Implementation Method 3
Glass-ceramic plates have a high transmittance to thermal radiation or the electric field of induction heating
Implementation Method 4
It is preferred that the upper heating plate touches foodstuffs of different thicknesses. This can be achieved by a vertically flexible, for example vertically guided and/or spring-loaded mounting of one and preferably the upper heating plate.
