Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking appliances lack advanced control mechanisms that enhance operational safety and comfort while allowing for expanded functionalities through external control devices, which are not effectively integrated with existing safety protocols.
Innovation Solution
A method for controlling cooking appliances using an external control device that classifies itself as either manual or automatic, providing control commands to the appliance's internal controller, with continuous checks to ensure safety and adapt operation based on classification changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external control device is integrated with a cooking appliance to expand functionalities and improve operating comfort, then the ease of operation and adaptability are improved, but the operational safety and reliability may deteriorate due to lack of proper safety protocols
Solution Approach 1:
The patent introduces an intermediary classification mechanism that mediates between the external control device and the cooking appliance. The controller classifies the external device as either manual or automatic, and this classification acts as an intermediary layer that determines which safety protocols are applied. This resolves the contradiction by allowing expanded functionality through external devices while maintaining safety through classification-based protocol selection.
Solution Approach 2:
The patent changes the parameter of safety protocol selection based on the classification parameter of the external control device. When classified as manual, less restrictive protocols apply; when classified as automatic, more stringent safety protocols are activated. This dynamic parameter change allows the system to adapt safety levels according to the type of external device being used.
2Adaptability or versatility
If the cooking appliance implements new functions through external control devices, then the adaptability and functionality are expanded, but the device complexity increases
Solution Approach 1:
The patent makes the controller universal by enabling it to work with multiple types of external control devices (both manual and automatic). The classification mechanism allows the same controller to handle different device types and apply appropriate protocols, rather than requiring separate controllers for different scenarios. This reduces overall system complexity while maintaining expanded functionality.
Solution Approach 2:
The patent introduces dynamic classification that allows the system to adapt its behavior based on the type of external device connected. The controller dynamically determines whether an external device is manual or automatic and adjusts its operation accordingly. This dynamic approach allows the system to maintain simplicity while supporting multiple functions through different device types.
3Ease of operation
If the external control device is classified as automatic to enable program sequences, then the ease of operation is improved, but the need for continuous safety checks increases device complexity
Solution Approach 1:
The patent performs preliminary classification of the external control device as manual or automatic before operation begins. This preliminary action determines which safety protocol set will be applied throughout operation. By classifying the device type in advance, the system can prepare appropriate safety checks without needing complex continuous monitoring for all device types, thus reducing overall complexity while maintaining safety.

AI summary
In a method for controlling a cooking appliance having heating devices and an internal cooking appliance controller by means of an external control device which is arranged outside the cooking appliance and may be a mobile telephone, this external control device provides the cooking appliance controller with control commands. The external control device is classified by the cooking appliance controller either as an automatic control device or as a manual control device, wherein its control commands are implemented by the cooking appliance controller after the classification. A check is carried out continuously or at intervals during operation of the cooking appliance in order to determine whether the classification still applies.
