Automatic cooking pot notifying completion of cooking and having a power switch in sync with a closing wing or knob protrusion for selectively waterproofing a sound passage hole
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cooking pots lack an efficient method to automatically notify the completion of broth food cooking with broth remaining, requiring manual intervention and inconvenient timer settings, especially for broth-based dishes like ramen where the cooking material is inputted before water boils.
Innovation Solution
An automatic cooking pot with a menu selection unit that sets a 'boiling sustainment time' on a timer unit, a boiling detection unit to initiate the timer upon boiling, and an alarm system to notify cooking completion, allowing for automatic notification of cooking completion without manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a manual timer is installed in a conventional cooking pot, then the user can set a predetermined time for cooking, but the user cannot accurately know when the cooking is completed and must frequently check the pot
Solution Approach 1:
The cooking pot automatically detects boiling through a temperature sensor and autonomously manages the cooking timer, eliminating the need for manual timer setting and frequent user checking. The system serves itself by monitoring cooking progress and notifying completion automatically.
Solution Approach 2:
The system continuously monitors temperature to detect boiling and provides feedback to the timer unit, which then automatically calculates and manages the cooking duration. This closed-loop feedback mechanism eliminates the need for manual intervention.
2Extent of automation
If a manual operation switch is provided for starting the timer, then the timer can be controlled, but the user must remember to operate the switch after checking boiling, causing inconvenience if forgotten
Solution Approach 1:
The timer unit automatically starts counting when the temperature sensor detects boiling, without requiring any manual switch operation. The system performs the timer activation function on its own, eliminating the need for user intervention.
Solution Approach 2:
The temperature sensor is pre-positioned to detect boiling automatically, and the timer unit is pre-programmed to start automatically upon detecting the boiling signal, eliminating the need for subsequent manual switch operation.
3Loss of information
If the user must frequently visit and check if water is boiling, then the user can ensure proper cooking timing, but this causes a lot of inconvenience when in use
Solution Approach 1:
The temperature sensor continuously monitors the cooking status and provides automatic feedback to the user through the alarm system, eliminating the need for frequent manual checking. The system informs the user of cooking completion automatically.
Solution Approach 2:
The manual visual checking process is replaced by an automated temperature sensing and alarm notification system, which electronically detects and communicates cooking status without requiring user presence or manual intervention.
4Object-generated harmful factors
If a sound passage hole is provided for alarm output, then the alarm can be heard, but water can penetrate into the alarm component during washing
Solution Approach 1:
The waterproof cover is designed to be movable, automatically opening when the alarm operates to allow sound passage, and closing when the alarm is inactive to prevent water penetration. This dynamic behavior adapts to different operational states.
Solution Approach 2:
The waterproof cover is pre-positioned in a closed state to prevent water penetration during washing, and automatically opens only when the alarm needs to sound, providing preliminary protection against water damage.

AI summary
The present invention relates to an automatic cooking pot notifying the completion of cooking. More specifically, provided is an automatic cooking pot which has a function of automatically notifying the optimal completion of a broth-based food, which retains a broth even when cooking is completed. Furthermore, if a user puts ingredients into the pot before the water boils, and selects a cooking menu wherein the same boiling time duration is set for the same menu regardless of the amount of food, the automatic cooking pot provided herewith notifies the user when the cooking is completed. In another embodiment, the user may adjust the boiling time duration to be set on a timer unit for the same food within a certain time range according to the amount of the food, on the basis of the variation in data in the boiling time durations depending on the amount of the food which have been measured through experiments beforehand.
