Solution Overview
Problem
Existing electric motor-operated food processors often fail to achieve consistent meal preparation quality due to deviations in food condition parameters such as humidity, temperature, and viscosity, which are not accurately accounted for in their processing programs.
Innovation Solution
The food processor incorporates sensors and environmental data to measure and adjust preparation parameters like mixing vessel temperature, agitator speed, and heating time based on real-time conditions, allowing for adaptive processing programs that account for initial and environmental values, ensuring optimal meal preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed preparation parameters are used in the processing program, then the device complexity is reduced and ease of operation is improved, but manufacturing precision and reliability deteriorate due to inability to account for variations in food condition parameters
Solution Approach 1:
The system continuously measures food condition parameters (temperature, humidity, viscosity) during processing and feeds this information back to the control unit, which automatically adjusts preparation parameters to maintain consistent quality despite initial variations in ingredients
Solution Approach 2:
The processing program dynamically changes preparation parameters (heating temperature, mixing speed, processing time) based on real-time measurements of food condition parameters, allowing the system to adapt to variations in ingredient state while maintaining preparation quality
2Reliability
If sensors and real-time measurement systems are added to measure food condition parameters, then manufacturing precision and reliability are improved, but device complexity increases
Solution Approach 1:
The food processor integrates multiple functions including mixing, heating, and sensing capabilities into a single device, with the control unit serving multiple purposes: program management, data processing, and automatic parameter adjustment based on sensor inputs
Solution Approach 2:
The system combines the measurement functions (temperature sensors, humidity sensors, viscosity measurement) with the processing functions (heating element, motor-driven mixer) and control functions into an integrated system where all components work together to achieve reliable meal preparation
3Manufacturing precision
If the system automatically adjusts preparation parameters based on measured values, then manufacturing precision is improved, but ease of operation may deteriorate due to reduced user control
Solution Approach 1:
The system performs self-adjustment of preparation parameters based on automatic measurements of food condition, eliminating the need for users to manually monitor and adjust settings, thereby maintaining high preparation accuracy while simplifying operation for the user

AI summary
The invention firstly relates to an electromotively driven kitchen appliance with a heatable stirring vessel formed to receive a stirring mechanism, the kitchen appliance being designed for automatic preparation of a dish according to a preset processing program. The invention also relates to a method for automatic preparation of a dish in an electromotively driven kitchen appliance having a heatable stirring vessel formed to receive a stirring mechanism. In order to provide an electromotively operated kitchen appliance and a method for automatic preparation of a dish, which appliance and/or method permit the greatest possible success in the preparation in respect of the properties and/or quality of the prepared dish, it is proposed that a device condition and/or environmental condition be measurable in respect of an environmental parameter such as stirring vessel temperature and/or air humidity or can be input as a value, that a measurement value thus obtained or input value can be compared with an initial value considered in the processing program, and that deviations from the initial value can be considered by automatic adaptation of preparation parameters contained in the processing program, such as heating time and/or heating temperature. In a subsequent step a change can be made, dependence on a change in a previous step.
