Oven Door With Integrated Display, Camera, And Thermal Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional oven doors lack enhanced visibility of information and effective thermal insulation, which limits user interaction and efficiency during food preparation.
Innovation Solution
The oven door features a transparent first wall element with an electronic display and an image capturing device between the door elements, providing a larger display area and improved thermal insulation using materials like glass wool, while the image capturing device records and displays the oven cavity's contents, allowing for multimedia content and user control through a touch-sensitive interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the oven door is made transparent to enable user monitoring, then visibility is improved, but thermal insulation deteriorates
Solution Approach 1:
The oven door is segmented into multiple wall elements (first door wall element, second door wall element) with distinct functional zones. The first wall element provides transparency for visibility, while the second wall element and intermediate space provide thermal insulation, allowing both functions to coexist without compromising either.
Solution Approach 2:
An intermediate space containing thermal insulation material (glass wool or stone wool) is introduced between the first and second door wall elements. This intermediary layer acts as a thermal barrier while allowing the door to maintain overall transparency through the first wall element, thus resolving the contradiction between visibility and thermal insulation.
2Loss of information
If a display is integrated in a panel above the oven door, then information can be provided to the user, but the display area is limited
Solution Approach 1:
The display is moved from a separate panel above the door to the surface of the door itself, utilizing the two-dimensional surface area of the door. This dimensional relocation allows the display to leverage the much larger available surface area of the door compared to a small control panel, thereby significantly increasing the display area while maintaining information provision functionality.
3Loss of energy
If the oven door is made opaque to improve thermal insulation, then heat retention is improved, but user monitoring capability deteriorates
Solution Approach 1:
An image capturing device (camera) is introduced as an intermediary between the oven cavity and the user. The camera captures images through the transparent first door wall element, allowing users to monitor the cooking process without direct line-of-sight through the door, thus maintaining both thermal insulation (through the intermediate space) and monitoring capability (through the imaging system).
Solution Approach 2:
The image capturing device creates visual copies (images) of the oven cavity contents, which are then displayed to the user. This copying mechanism allows users to monitor the cooking process indirectly through displayed images rather than direct viewing, enabling the door to be more opaque while maintaining monitoring capability through the captured image copies.
4Measurement precision
If electronic display and image capturing device are placed close to the oven cavity for better imaging, then monitoring quality is improved, but heat impact on components increases
Solution Approach 1:
The intermediate space containing thermal insulation material serves as a protective intermediary between the hot oven cavity and the electronic components (display and image capturing device). This intermediary layer reduces heat transfer to the components, allowing them to be positioned closer to the cavity for better imaging while protecting them from excessive heat through the insulating barrier.
