A multifunctional stationary boiling pan
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunctional stationary boiling pans face issues with manual control of the waste outlet leading to hygiene and safety risks due to human error, particularly when handling hot food or oil, which can cause spoilage or damage to sewer systems.
Innovation Solution
The implementation of an electromechanical drain valve controlled by a servomotor, coupled to a control unit that automatically adjusts the waste outlet position based on pre-programmed rules, ensuring hygienic and safe operation, with a backup power supply to maintain closure during power disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual control is used for the waste outlet, then the device complexity is reduced, but the reliability deteriorates due to human error causing food spoilage or sewer damage
Solution Approach 1:
The patent replaces the manual mechanical control system with an electromechanical control system. An electromechanical drain valve controlled by a servomotor substitutes the manual valve operation, eliminating human error while maintaining controlled waste outlet functionality. The control unit receives signals and automatically adjusts the drain valve position based on cooking state detection.
Solution Approach 2:
The control unit automatically detects the cooking state (presence of food, temperature, cooking phase) and autonomously controls the drain valve without requiring manual intervention. The system serves itself by making intelligent decisions about when to open or close the waste outlet based on pre-programmed rules and sensor feedback.
2Reliability
If the waste outlet is kept closed during cooking, then hygiene and safety are improved, but the ease of operation deteriorates as manual opening/closing is required
Solution Approach 1:
The manual operation of opening and closing the waste outlet is replaced by an electromechanical system. The servomotor-driven drain valve automatically opens or closes based on electrical signals from the control unit, eliminating the need for manual mechanical operation while maintaining hygiene and safety standards.
Solution Approach 2:
The control unit autonomously manages the waste outlet state based on detected cooking conditions. When food is present in the cooking vessel, the system automatically keeps the waste outlet closed; when the vessel is empty, it automatically opens, eliminating the need for operator intervention.
3Productivity
If hot oil is discharged through the waste outlet, then productivity is improved by quick waste removal, but object-affected harmful factors worsen due to damage to waste lines and sewer
Solution Approach 1:
The control unit continuously monitors the cooking state through temperature sensors and other detectors to determine when the cooking process is complete and the cooking vessel is empty. This feedback mechanism ensures the waste outlet is only opened when appropriate, preventing hot oil from being discharged into the waste line while allowing efficient waste removal when safe.
Solution Approach 2:
The system performs preliminary detection of the cooking state before allowing waste outlet operation. The control unit verifies that no food or hot oil remains in the vessel before commanding the drain valve to open, preventing harmful discharge while maintaining productivity through quick waste removal when conditions are safe.
