Cooking appliance with automatic timer and reminder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oven appliances lack automatic tracking of cooking time, leading to inaccurate cooking results when users forget to set a timer, resulting in undercooked or overcooked food.
Innovation Solution
A cooking appliance with a controller that automatically initiates a timer when the door is closed, allowing for accurate tracking of cooking time and providing notifications to the user if a manual timer is not set, ensuring proper cooking times are maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a manual timer is used, then the user can set a desired time, but the user may forget to activate it resulting in inaccurate cooking time tracking
Solution Approach 1:
The cooking appliance automatically initiates the timer function by detecting door closure, eliminating the need for manual user input. The system serves itself by autonomously starting time tracking when the door is closed, ensuring accurate cooking time measurement without requiring user intervention or memory.
2Measurement precision
If automatic timer initiation is implemented, then cooking time tracking accuracy is improved, but device complexity increases
Solution Approach 1:
The timer initiation function is merged with the existing door closure detection mechanism. The same sensor that detects when the door is closed for cooking is also used to automatically start the timer, combining two functions into one detection event without adding separate complexity.
Solution Approach 2:
The system is pre-programmed with the logic to automatically start the timer upon door closure detection. This preliminary programming allows the appliance to autonomously initiate time tracking without requiring additional hardware complexity or user intervention during operation.
3Measurement precision
If the timer is automatically initiated on door closure, then accurate cooking time is tracked, but the user loses control over when the timer starts
Solution Approach 1:
The system provides feedback to the user about the automatic timer initiation. When the door is closed and the timer automatically starts, the appliance notifies the user of this action, allowing the user to verify that the timer is running and to manually adjust or stop it if needed, thus maintaining user awareness and control.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution ensures accurate cooking times are maintained, reducing the risk of undercooked or overcooked food by automatically tracking cooking time and providing timely notifications to users.
Implementation Method 1
a heating element disposed within the cabinet and in thermal communication with the cooking chamber for cooking the food items received in the cooking chamber
Implementation Method 2
The controller is further configured for detecting an opening and a closing of the door of the cooking appliance
Data Source
AI summary
A method of operating a cooking appliance includes receiving an input from a user interface of the cooking appliance. The input includes a set temperature. In response to the received input, a heating element of the cooking appliance is activated. The method also includes detecting an opening and a closing of a door of the cooking appliance. The method further includes automatically initiating a timer when the closing of the door is detected.
