Control- and operating device for a cooking appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control and operating devices for pressure cookers primarily focus on displaying actual temperature and pressure conditions, failing to account for individual taste preferences, which limits their ability to provide customized cooking results.
Innovation Solution
A control, regulation, and operating device for pressure cookers that integrates a setting device for multiple cooking degrees, incorporates a data memory for food-specific data, and utilizes sensors and a microcontroller to adjust cooking processes based on user preferences and the Reaction Speed Temperature (RGT) rule, allowing for precise temperature and pressure monitoring and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a spring mechanism is used to display internal pressure, then the user can influence the cooking process, but the display becomes inaccurate due to manufacturing tolerances and temperature fluctuations
Solution Approach 1:
The patent replaces the mechanical spring mechanism with an electronic pressure sensor and microcontroller-based display system. The electronic sensor provides accurate pressure measurement independent of temperature fluctuations, while the microcontroller processes the data to display precise pressure values, eliminating the inaccuracies inherent in mechanical spring systems.
Solution Approach 2:
The patent uses an electronic representation (digital display) to copy and represent the physical pressure state, rather than relying on the physical deformation of a spring. This electronic copy provides accurate information about the pressure state without being subject to the physical limitations of mechanical components.
2Adaptability or versatility
If a spring-loaded system is used for pressure display, then relative pressure values can be shown, but absolute pressure values are not available making it problematic under different weather conditions or altitudes
Solution Approach 1:
The electronic pressure sensor measures absolute pressure values directly, independent of external conditions. The microcontroller processes these absolute values and can display them accordingly, providing accurate pressure information whether the cooker is used at sea level or at high altitude, unlike mechanical spring systems that only provide relative measurements.
3Loss of information
If only actual temperature and pressure conditions are displayed, then the cooking process can be monitored, but individual taste preferences cannot be taken into account
Solution Approach 1:
The patent allows users to pre-set their preferred cooking parameters (temperature, pressure, time) before starting the cooking process. The microcontroller stores these preferences and automatically adjusts the cooking process to match the user's taste preferences, eliminating the need for users to manually adjust settings during cooking.
Solution Approach 2:
The system continuously monitors the actual cooking parameters via sensors and compares them with the user's preferred settings. The microcontroller adjusts the heating element and pressure regulation in real-time to maintain the desired cooking conditions, providing feedback control that ensures the cooking process matches user preferences.

Function Achieved in This Case
Enables cooking results tailored to individual taste preferences, ensuring reproducibility without requiring extensive user knowledge, and allows for customizable cooking levels and user profiles, accommodating diverse culinary needs.
Implementation Method 1
the internal pressure in the pressure cooker is displayed to him with the help of a spring mechanism, the springs of the spring mechanism usually being subject to both manufacturing tolerances and temperature fluctuations in their properties
Implementation Method 2
Via at least one sensor device, the control, regulation, and operating device is able to detect at least one parameter influencing a cooking process, such as pressure and/or temperature inside and/or outside the cooking appliance
Implementation Method 3
the control, regulation, and operating device can, for example, influence a valve device on the cooking appliance and/or influence the heating output
