Closed-Loop Cooking Power Cycle Selection for Adaptive Thermal Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional closed-loop cooking appliances have a fixed power cycle period, which limits their ability to adjust rapidly and appropriately to changing cooking conditions, leading to inefficiencies in power delivery, especially for foods with sensitive thermal properties.
Innovation Solution
A method where a controller in the appliance determines and adjusts the power cycle period based on input parameters such as food type, quantity, and cooking technique, allowing for dynamic control of the cooking operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed power cycle period is used, then the control system is simple, but the appliance cannot adjust rapidly and appropriately to changing cooking conditions
Solution Approach 1:
The patent applies dynamics by transitioning from a fixed power cycle period to a variable power cycle period that adapts based on cooking conditions. The controller dynamically adjusts the cycle period length based on feedback from temperature sensors and cooking stage detection, enabling the system to respond rapidly to changing cooking requirements while maintaining manageable complexity through algorithmic control.
Solution Approach 2:
The patent changes the parameter of power cycle period from a fixed value to a variable parameter that can be adjusted based on cooking conditions. The controller modifies the cycle period length according to detected cooking stages, food type, and temperature requirements, allowing rapid adaptation without requiring complete system redesign.
2Manufacturing precision
If a fixed power cycle period is used, then the control algorithm is simple, but the power delivery is not precise for foods with sensitive thermal properties
Solution Approach 1:
The patent implements feedback control by continuously monitoring cooking conditions through temperature sensors and detecting cooking stages. The controller uses this feedback information to adjust the power cycle period dynamically, achieving precise power delivery for temperature-sensitive foods while maintaining cooking efficiency through automated stage-based control.
Solution Approach 2:
The patent uses periodic action with variable period lengths to deliver precise power to the cooking element. By adjusting the cycle period and duty cycle based on detected cooking stages and food requirements, the system achieves precise thermal control for sensitive foods while maintaining overall cooking efficiency through structured periodic operation.
