Connected Oven Panel Cooling for Touchscreen Heat Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of touchscreens and high-computational control systems in ovens poses a thermal management challenge due to their heat sensitivity, as these components are exposed to thermal radiation from the cooking cavity, leading to potential damage and reduced lifespan.
Innovation Solution
A thermal management system is implemented using fluid channels and thermally insulative materials to separate heat-sensitive components from the cooking cavity, incorporating dual-panel designs and air gaps to facilitate cooling and reduce thermal exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If touchscreens and control systems are integrated into the oven structure to reduce footprint, then device compactness is improved, but thermal exposure to heat-sensitive components increases
Solution Approach 1:
The oven structure is segmented into multiple panels (primary and secondary panels) that define separate fluid channels. Heat-sensitive components are isolated in specific zones within these panels, physically separating them from the cooking cavity while maintaining overall compactness.
Solution Approach 2:
Fluid channels act as intermediary pathways between the cooking cavity and the exterior. These channels carry fluid that absorbs thermal radiation and transfers it away from heat-sensitive components, mediating the thermal interaction while allowing close integration of components.
2Reliability
If fluid channels are incorporated for thermal management, then thermal protection of components is improved, but device complexity increases
Solution Approach 1:
The thermal management function is merged into the structural panels themselves. The primary and secondary panels are designed to define fluid channels as an integral part of their construction, combining structural support with thermal management rather than adding separate cooling systems.
Solution Approach 2:
The fluid channels serve multiple functions: they provide thermal management for heat-sensitive components, enable aesthetic design variations through different configurations, and can be integrated with existing oven structures without requiring completely separate systems.
3Temperature
If dual-panel designs with air gaps are used to thermally insulate components, then thermal insulation performance is improved, but manufacturing complexity increases
Solution Approach 1:
The insulation structure is segmented into discrete primary and secondary panels that can be manufactured separately using standard fabrication processes. The air gap is created by the spacing between these standardized panels, simplifying manufacturing compared to monolithic insulated structures.
Solution Approach 2:
The air gap between panels provides automatic thermal insulation without requiring additional insulating materials or complex assembly procedures. The design uses the natural properties of air as an insulator, eliminating the need for separate insulation components.
