A cooking device with a sensor device mounted elastically below the support device, using a damping system and magnetic shielding, allows for precise non-contact temperature measurement of cooking vessels while protecting against mechanical impacts and electromagnetic interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sensor device is arranged directly below the support device for accurate temperature detection, then measurement precision is improved, but the support device becomes vulnerable to mechanical damage from impacts
Solution Approach 1:
The patent applies beforehand cushioning by introducing a damping device between the sensor device and the support device. This damping device absorbs mechanical impacts before they can reach the sensor device, protecting it from damage while maintaining its close proximity to the support device for accurate temperature detection. The damping device acts as a protective buffer that is pre-positioned to cushion against potential impacts from cookware or other objects.
2Measurement precision
If the sensor device is positioned close to the support device for accurate measurement, then measurement precision is improved, but the sensor device becomes vulnerable to mechanical loads
Solution Approach 1:
The patent applies the intermediary principle by introducing a damping device as a mediator between the sensor device and the external environment. This damping device serves as an intermediary element that transmits thermal signals for accurate measurement while filtering out harmful mechanical impacts. The damping device acts as a protective intermediary that allows the sensor to remain close to the support device for accurate detection without being directly exposed to mechanical hazards.
3Measurement precision
If a rigid arrangement of the sensor device is used for stable positioning, then measurement precision is improved, but damage occurs during mechanical impacts
Solution Approach 1:
The patent applies parameter changes by transforming the mechanical coupling characteristics between the sensor device and the support device. Instead of a rigid fixed connection, the damping device introduces viscoelastic or viscous damping characteristics that allow the sensor device to maintain stable positioning for accurate measurement while accommodating mechanical impacts through controlled deformation. The damping device changes the mechanical parameters of the connection from rigid to compliant, enabling both stable positioning and impact resistance.
