Cooking Oven Camera Cooling and Heat Isolation for Clear Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ovens with external cameras struggle to capture the inside of the cooking compartment clearly due to phase diffuse reflection caused by the glass on the oven door, leading to poor image quality and potential camera malfunction from heat exposure.
Innovation Solution
An oven design featuring a camera positioned above the cooking compartment with a camera cooling fan and multiple glass layers to block heat transmission, including a first glass at the opening and a second glass between the camera and the first glass, to prevent heat from reaching the camera, ensuring clear capture and maintaining the camera's temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an external camera is used to capture the cooking compartment through the door glass, then the camera can be positioned outside the cooking compartment, but phase diffuse reflection occurs due to the glass property causing poor image quality
Solution Approach 1:
A separate glass plate is introduced as an intermediary component between the camera and the cooking compartment. This glass plate is specifically positioned and configured to minimize phase diffuse reflection, thereby improving image quality while maintaining the external camera positioning advantage
Solution Approach 2:
The glass plate is positioned at a specific location and angle optimized for capturing images of the cooking compartment. By locally optimizing the glass placement rather than using the door glass directly, the system achieves both external camera positioning and reduced reflection interference
2Measurement precision
If the camera is positioned above the cooking compartment for clear capture, then image quality improves, but the camera temperature increases due to heat exposure causing potential malfunction
Solution Approach 1:
The glass barrier is divided into multiple layers (first glass and second glass) with the camera positioned between them. This segmentation creates thermal zones where the cooking compartment heat is blocked by the glasses, while the camera resides in a cooler zone, thus protecting the camera from excessive heat exposure
Solution Approach 2:
The first and second glasses act as intermediary thermal barriers between the hot cooking compartment and the camera. These glass layers block heat transmission while allowing optical transmission, thereby maintaining clear image capture capability while protecting the camera from thermal damage
3Temperature
If multiple glass layers are added to block heat transmission to the camera, then camera temperature control improves, but device complexity increases
Solution Approach 1:
The glass layers serve multiple functions simultaneously: they act as thermal barriers to block heat transmission to the camera, while also serving as optical windows that allow the camera to capture images of the cooking compartment. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity
