Cooking Vessel Lid Release Based on Vortex Dissipation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooking vessels with agitators and heating devices pose a risk of hot food escaping and causing injuries when the lid is opened prematurely, due to pressure increases and slow vortex dissipation after operation.
Innovation Solution
A method where the lid is released based on recorded data, such as agitator speed and heating temperature, after a predetermined period to ensure safety, allowing the lid to be lifted only when the vortex has receded, with optional manual or motor-controlled release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lid is locked during agitator and heating operation to prevent hot food escape, then operator safety is improved, but the waiting time before lid can be opened increases
Solution Approach 1:
The control unit calculates the vortex dissipation time in advance based on recorded agitator speed and heating temperature data, and determines the lid release timing before the operator attempts to open the lid. This preliminary calculation allows the system to prepare for safe lid release without requiring the operator to wait unnecessarily long.
Solution Approach 2:
The system uses recorded data from agitator speed sensors and heating temperature sensors to continuously monitor the cooking process state. This feedback information is fed into the control unit to dynamically determine when the vortex has dissipated sufficiently and the lid can be safely released, optimizing the balance between safety and waiting time.
2Productivity
If the lid is released immediately after switching off the agitator to reduce waiting time, then productivity is improved, but the risk of hot food splashing and operator injury increases
Solution Approach 1:
The control unit performs preliminary calculations of the vortex dissipation time based on recorded agitator speed and heating temperature data before the lid release moment. This allows the system to determine the optimal release timing in advance, ensuring the vortex has dissipated sufficiently to prevent hot food splashing while minimizing unnecessary waiting time.
Solution Approach 2:
The system replaces manual judgment of vortex dissipation with an automated control unit that uses recorded sensor data to calculate the dissipation time. This substitution of mechanical/operator-based timing with electronic calculation and control ensures more precise and reliable determination of safe lid release timing.
3Speed
If agitator speed and heating temperature are increased to improve cooking performance, then cooking speed is improved, but the vortex dissipation time increases and safety risk increases
Solution Approach 1:
The control unit continuously monitors recorded data from agitator speed sensors and heating temperature sensors to determine the actual vortex dissipation time. When high cooking speeds and temperatures are used, the system automatically extends the calculated waiting period based on the recorded parameters, ensuring safe lid release timing that adapts to the intensity of the cooking process.
Solution Approach 2:
The system dynamically adjusts the lid release timing based on changes in operating parameters such as agitator speed and heating temperature. When these parameters indicate intense cooking conditions that prolong vortex dissipation, the control unit automatically modifies the release timing to account for the extended dissipation period, maintaining safety across different cooking intensities.

AI summary
The agitator and/or heating data of the cooking vessel (7) are detected and stored. The stored data is compared with preset data, and the release of the lid (12) is determined based on the comparison of stored data with the preset data in a specific period. An independent claim is included for a food processor.
