Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a temperature sensor is attached directly to the induction heating coil or cooktop plate, then temperature detection is achieved, but the mounting becomes complex and may interfere with the heating element
Solution Approach 1:
The patent introduces an intermediate holding device made of plastic that serves as a mediator between the temperature sensor and the cooktop structure. This holding device simplifies the mounting process by providing a pre-fabricated attachment mechanism with mounting sections that can be easily secured to the cooktop plate, eliminating the need for complex direct mounting arrangements while maintaining temperature detection accuracy.
2Reliability
If a temperature sensor is pressed against the cooktop plate with elastic elements, then secure attachment is achieved, but the structure becomes more complex and may affect heating efficiency
Solution Approach 1:
The patent combines multiple functions into the holding device: it integrates the sensor mounting function, the attachment to cooktop structure function, and the positioning function into a single plastic component. The holding device incorporates mounting sections that can be secured to the cooktop plate and simultaneously holds the temperature sensor in the correct position, eliminating the need for separate elastic pressing elements and complex holding structures.
3Measurement precision
If a sensor device is installed in the cooktop, then temperature monitoring is enabled, but the installation process becomes cumbersome and time-consuming
Solution Approach 1:
The holding device is pre-fabricated with integrated mounting sections and sensor positioning features before installation. The temperature sensor is pre-mounted in the correct orientation within the holding device, and the mounting sections are prepared with appropriate attachment mechanisms. This preliminary preparation allows for rapid installation by simply securing the entire holding device to the cooktop plate, significantly reducing installation time while ensuring correct sensor positioning for accurate temperature measurement.

AI summary
A sensor device for a cooktop comprises a sensor element and a plastic mounting device for it. The mounting device has an upper mounting area in which the sensor element is held in a precisely positioned position and a mounting section connected to the mounting area. The mounting section projects perpendicularly from a longitudinal direction of the mounting area and has mounting projections and recesses for a positive-locking attachment of the sensor device to the outer surface of a heating element of the cooktop. The at least one mounting projection extends laterally to engage with the heating element in order to be attached to it.
