Method for controlling a cooking appliance with an external control device, cooking device and system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliance control systems lack effective measures to ensure operational safety, particularly when using external control devices for remote operation, as they do not adequately differentiate between manual and automatic control modes, leading to potential safety risks.
Innovation Solution
A method and system that classify external control devices as either manual or automatic, allowing for differentiated safety precautions, where manual control devices require operator presence and intervention, while automatic control devices can operate independently, with continuous monitoring to adjust safety measures based on classification accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If external control devices are used to operate cooking appliances remotely, then ease of operation is improved, but operational safety deteriorates due to inadequate differentiation between manual and automatic control modes
Solution Approach 1:
The patent segments external control devices into two distinct categories: manual control mode and automatic control mode. This segmentation allows the system to apply different safety measures and operational rules depending on the control type, thereby maintaining ease of remote operation while ensuring appropriate safety precautions are taken for each mode.
Solution Approach 2:
The patent changes the operational parameters and safety requirements based on the control mode parameter. When an external control device is identified as operating in automatic mode, the system applies stricter safety parameters and monitoring requirements compared to manual mode, thus adapting safety measures to the specific operational context.
2Adaptability or versatility
If multiple external control devices operate simultaneously, then adaptability is improved, but control reliability deteriorates due to potential conflicts and safety management issues
Solution Approach 1:
The patent implements dynamic safety management that adapts to the current operational context. When multiple external control devices are operating simultaneously, the system dynamically adjusts safety measures based on the combination of control modes active, the type of cooking process, and real-time operational status, ensuring control reliability is maintained despite multiple devices being involved.
Solution Approach 2:
The system continuously monitors the operational status and control mode of all external control devices, providing feedback to the control unit. This feedback mechanism enables the system to detect potential conflicts, verify operator presence when required, and adjust safety measures in real-time to maintain reliable operation across multiple devices.

AI summary
In a method for controlling a cooking appliance with heating elements and an internal cooking appliance control unit by means of an external control device located outside the cooking appliance (which may be a mobile phone), this external control device sends control commands to the cooking appliance control unit. The cooking appliance control unit classifies the external control device as either an automatic or a manual control unit, and its control commands are implemented by the cooking appliance control unit according to this classification. During operation of the cooking appliance, the classification is checked continuously or at intervals to ensure it is still valid.
