Cooktop Interactive Display Assembly with Thermistor-Activated Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooktop systems fail to provide a satisfactory user experience due to the limitations of printed recipe materials and electronic devices, which are often cumbersome, prone to damage, and unsuitable for use near cooking environments, lacking real-time interaction and protection from heat and steam.
Innovation Solution
A system comprising an interactive assembly with a casing, an image monitor, an air handler, and a thermistor, where the controller activates the air handler based on temperature signals from the thermistor to move air across the image monitor, protecting it from heat and steam while allowing for real-time interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an electronic device (computer, tablet, smartphone) is used for recipe guidance, then real-time interaction and information access are improved, but the device is damaged by heat, steam, and condensation in the cooktop environment
Solution Approach 1:
The system separates the electronic components (monitor, controller) from the cooking area by placing them in a protected housing above the cooktop, while the thermistor remains in the cooking environment. This segmentation allows the electronic device to provide real-time information without being exposed to damaging heat and steam.
Solution Approach 2:
The thermistor acts as an intermediary sensor that monitors temperature in the cooking environment and transmits signals to the controller, which then controls the air handler. This intermediary approach allows the system to respond to cooking conditions without requiring the electronic components to be directly exposed to the harsh environment.
2Ease of operation
If a display is positioned near the cooktop for user engagement, then user interaction during cooking is improved, but the display becomes obscured by food, steam, and condensation
Solution Approach 1:
The display is extracted from the cooking environment and placed in a protected housing above the cooktop, removing it from direct exposure to steam and food particles that cause obscuration, while maintaining its accessibility for user interaction.
Solution Approach 2:
The air handler uses pneumatic airflow to create a protective barrier of air across the display surface, preventing steam and condensation from reaching and obscuring the display, thereby maintaining visibility during cooking operations.
3Reliability
If the air handler is activated continuously to protect the image monitor, then protection from heat and steam is improved, but energy consumption increases
Solution Approach 1:
The air handler operates periodically rather than continuously, activating when the thermistor detects elevated temperature conditions and deactivating when temperatures return to normal levels. This periodic operation maintains image monitor protection while significantly reducing energy consumption compared to continuous operation.
Solution Approach 2:
The thermistor provides continuous temperature feedback to the controller, which automatically activates or deactivates the air handler based on real-time temperature conditions. This feedback mechanism ensures the air handler operates only when necessary for protection, optimizing both reliability and energy efficiency.
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
The system enhances user engagement by providing a protected and functional display for viewing images and information near a cooktop, preventing damage from heat and steam, and maintaining visibility during cooking operations.
Implementation Method 1
a thermistor mounted to or within the casing. The controller is configured to: receive, from the thermistor, one or more signals indicative of a temperature level of air proximate the thermistor
Implementation Method 2
activate the air handler based at least in part on whether the temperature level has exceeded the predetermined activation threshold so that air is moved across or about the image monitor
Data Source
AI summary
A cooking engagement system and methods therefore are provided. The system includes a cooktop appliance and an interactive assembly positioned above the cooktop appliance. The interactive assembly includes an image monitor that presents various images and information to a user, e.g., recipes. The system includes a thermistor for detecting operation of the cooktop appliance. When the thermistor senses a temperature level that exceeds a threshold, a controller communicatively coupled thereto activates an air handler to move or motivate an airflow across or about the image monitor. In this way, the image monitor may be cooled and condensation is prevented from forming on the imaging surface of the image monitor.
