Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing temperature measurement methods in kitchen appliances are limited to single appliance use, are complex to manufacture, and inconvenient for users, as they require wired connections or are restricted to local monitoring within the appliance.
Innovation Solution
A method and system that allows temperature data from one kitchen appliance to be transmitted to another or an external device for coordinated cooking processes, using wireless communication and surface acoustic wave sensors, enabling inter-appliance coordination for efficient food preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired temperature sensors are used in kitchen appliances, then temperature measurement is reliable, but the cable must be led through seals which increases production complexity and reduces user convenience
Solution Approach 1:
The patent replaces wired mechanical temperature sensors with wireless temperature sensors that communicate via radio frequency. This eliminates the need for physical cable connections through appliance seals, thereby reducing production complexity while maintaining temperature measurement reliability through wireless signal transmission.
Solution Approach 2:
The patent introduces a wireless communication intermediary (radio frequency transceiver system) between the temperature sensor and the control unit. This intermediary enables temperature data transmission without physical cable connections, solving the contradiction between reliable measurement and production simplicity.
2Device complexity
If wireless temperature sensors are used, then production complexity is reduced, but the measurement result is only available to the same kitchen appliance limiting inter-appliance coordination
Solution Approach 1:
The patent implements a universal wireless communication interface that enables temperature data from any kitchen appliance to be transmitted to and utilized by other kitchen appliances. This multi-functional communication system allows a single wireless sensor to serve multiple appliances, enhancing adaptability and coordination capabilities while maintaining production simplicity.
Solution Approach 2:
The patent extends the communication dimension from local (single appliance) to remote (multiple appliances via network). By adding the network communication dimension, temperature data can be shared across different appliances and even remote devices, transforming the system from isolated to interconnected while keeping the sensor design simple.
3Ease of operation
If temperature data is transmitted to external devices, then user convenience is enhanced through remote monitoring, but data transmission complexity increases
Solution Approach 1:
The patent implements automatic temperature data transmission where the wireless temperature sensor autonomously sends data to external devices without requiring complex user configuration. The system self-manages the communication process, reducing the perceived complexity for users while maintaining ease of operation through automatic connectivity.
Solution Approach 2:
The patent establishes preliminary communication protocols and network connections before actual temperature monitoring begins. By pre-configuring the wireless communication framework, the system reduces transmission complexity during actual use, allowing users to benefit from remote monitoring without dealing with complex setup procedures.

AI summary
The invention relates to a method for measuring a temperature inside a kitchen appliance (1), in particular the temperature of an item to be cooked (21) to be cooked inside a kitchen appliance (1), with the method steps: transmission of an electromagnetic excitation signal by means of a transceiver (2) , receiving the excitation signal by a temperature sensor (3) arranged in the kitchen appliance (1), in particular in the food to be cooked (21), sending a temperature-dependent response signal by the temperature sensor (3), receiving the response signal by the transceiver (2 ), determining the current temperature by comparing the response signal with temperature-dependent reference signals. In order to also enable interaction between several kitchen appliances (1, 4), it is proposed that the transceiver (2) transmit the response signal or partial information of the response signal and/or the amount of a determined current temperature to a control device of another kitchen appliance (4) or to an external computer (5). In addition, a system for carrying out a method according to the invention is proposed.
