Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Kitchens are often under-ventilated, and existing range hood controls are not effectively automated, leading to inefficient ventilation, potential health hazards, and energy waste due to the lack of real-time monitoring and control over cooking processes on stovetops.
Innovation Solution
An integrated system combining sensors in stoves and range hoods with a shared controller that monitors air quality and burner activity, allowing for automated adjustments of ventilation and cooking parameters to prevent smoke, carbon monoxide, and energy inefficiencies, while providing user-selectable intervention levels for different cooking scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual range hood control is used, then users have full control over ventilation timing, but kitchens remain under-ventilated and air quality deteriorates due to delayed hood activation
Solution Approach 1:
The system uses sensors to detect cooking conditions (heat, smoke, steam) and provides feedback to the controller, which automatically adjusts hood operation. This closed-loop feedback mechanism resolves the contradiction by enabling automatic response to actual cooking needs while maintaining user-defined preferences through programmable cooking programs.
Solution Approach 2:
The range hood system performs self-service by automatically detecting when cooking is occurring through sensors and activating ventilation without manual user input. The system monitors cooking conditions and independently controls hood operation, eliminating the need for users to manually switch on the hood while ensuring proper ventilation.
2Productivity
If automatic range hood control is implemented, then ventilation responsiveness improves, but device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The system achieves multi-functionality by using a single controller that manages both stove cooking programs and range hood ventilation operations. Sensors serve multiple purposes by detecting various cooking conditions (heat, smoke, steam) that trigger different ventilation responses. This universal approach improves ventilation responsiveness while minimizing additional complexity through shared control infrastructure.
Solution Approach 2:
The patent combines the stove control system and range hood control system into a unified integrated system. The controller merges cooking program management with ventilation control, and the sensor array consolidates multiple detection functions into a single monitoring platform. This merging reduces overall system complexity while enhancing ventilation responsiveness through coordinated control.
3Reliability
If continuous monitoring of cooking processes is implemented, then safety and energy efficiency improve, but energy consumption by the monitoring system increases
Solution Approach 1:
The system employs periodic monitoring through programmable cooking programs that define specific monitoring intervals and activation conditions. Sensors operate continuously but the controller processes data periodically based on programmed cooking stages, triggering ventilation and alerts only when threshold conditions are met. This periodic action maintains high reliability for safety monitoring while reducing overall energy consumption compared to continuous full-system operation.
4Ease of operation
If pre-programmed cooking settings are provided, then ease of cooking operation improves, but adaptability to different cooking scenarios decreases
Solution Approach 1:
The system achieves dynamic adaptability by allowing users to programmably configure cooking parameters (temperature, time, ventilation levels) for different cooking scenarios. The controller dynamically adjusts ventilation and cooking parameters based on real-time sensor feedback and programmed settings. This dynamic configuration capability enables the system to adapt to various cooking needs while maintaining ease of operation through automated control once programs are set.

AI summary
System and method for improving the performance, safety, and energy efficiency of a cooking appliance with one or more heating elements operably connected with a burner controller controlling an amount of energy flowing to the one or more heating elements. First, a user or a system controller establishes one or more reference levels. The system controller is operably associated with one or more sensors, which measures levels of one or more emissions generated in the operation of the cooking appliance. Afterwards, the system controller compares the measured levels of the one or more emissions with the reference levels and in response to the measured levels of the emissions exceeding reference levels, sends an activation control signal to the cooking appliance. Then, an energy control mechanism associated with the burner controller adjusts the amount of energy flowing to the heating elements in response to the activation control signal.
