Method, computer program and control device for controlling a cooking appliance and cooking appliance system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling cooking appliances via mobile devices are susceptible to interference and user-unfriendliness due to signal strength fluctuations, leading to unreliable operation.
Innovation Solution
A method that captures multiple sample values of wireless data connection signal strength, determines a test value, and compares it to a reference value to limit controllability, ensuring robust and safe control by preventing control at distances where signal quality is inadequate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If signal strength threshold control is implemented, then reliability of cooking appliance control is improved, but ease of operation deteriorates due to blocking of commands
Solution Approach 1:
The patent applies dynamics by making the control state adaptive rather than static. The system dynamically switches between blocked and unblocked states based on real-time signal strength evaluation. When signal strength exceeds the threshold, control is unblocked; when it falls below, control is blocked. This dynamic adaptation resolves the contradiction by allowing the system to maintain reliability (through blocking when signal is poor) while preserving ease of operation (by unblocking when signal is good).
Solution Approach 2:
The patent implements feedback by continuously monitoring signal strength and using this information to adjust the control state. The signal strength measurement feeds back to the control logic, which then determines whether to block or allow control commands. This closed-loop feedback mechanism resolves the contradiction by ensuring that control reliability is maintained through feedback-driven blocking only when necessary, rather than permanently blocking control.
2Ease of operation
If remote control via mobile device is enabled, then ease of operation is improved, but reliability deteriorates due to signal interference
Solution Approach 1:
The patent introduces an intermediary control mechanism that mediates between the mobile device and the cooking appliance. The control device acts as an intermediary that evaluates signal strength and selectively passes or blocks control commands. This intermediary resolves the contradiction by enabling ease of operation (remote control functionality) while protecting reliability (by blocking commands when signal interference is detected).
Solution Approach 2:
The patent implements a two-layer control structure where the control device creates a virtual representation or copy of the signal quality assessment to make control decisions. Instead of the mobile device directly controlling the appliance, the control device creates an intermediate control layer that copies the necessary control information only when signal quality is sufficient. This resolves the contradiction by maintaining ease of operation through remote interface while ensuring reliability through the copying/filtration layer.

AI summary
A method for controlling a cooking appliance of the basis of a control command transferred from a mobile device to a control device via a wireless data connection, comprising the steps of: capturing a plurality of the sample values correlating to a signal strength of the wireless data connection, determining a test value on the basis of the plurality of sample values, comparing the test value with a reference test value to determine a comparison result, limiting the controllability of said cooking appliance by means of the mobile device according to the comparison result.
